BMW Engines - Buyer's Guide

AT this review showcasing BMW petrol and diesel engines that have been in use for the past 15 years. Due to the huge range of power units of the Bavarian company, we cannot cover all engines and their options. Nevertheless, we will dwell in detail on the most famous and popular motors.

BMW is one of the world's leading manufacturers, offering the most modern and advanced powertrains on the market. Therefore, you need to be prepared for large bills for maintenance and repairs. You don’t have to look far for examples - for many owners it comes as a surprise that the need to periodically replace the timing chain drive used in all modern BMW engines comes as a surprise. The chain and tensioner, as a rule, take care of about 200-300 thousand km. This creates noise, and the engine runs unevenly. To replace the timing chain, it is necessary to prepare about 20-30 thousand rubles. In the case of old copies, difficulties arise when trying to overhaul - the materials used to make the cylinder liners do not allow them to be restored.

What expenses await you after buying a used BMW depends on the condition of the car and the version of the engine under the hood. Our review will certainly help to make right choice.

The N42 and N46 engines, produced from 2001 to 2007, are among the most popular four-cylinder BMW units in the world. secondary market, mainly due to the "troika" E46 and the Compact version based on it. These motors can be found in the "ones" E87 and "triples" E90 of the initial production period. It is believed that a BMW with a 4-cylinder engine is not a real BMW. But honestly, these little engines are unique. technical masterpieces. Both are equipped with a timing chain drive, both have the Double VANOS system - a system for adjusting the valve timing of the intake and exhaust valves, as well as the Valvetronic system - an original solution for smoothly changing the lift height intake valves replacing usual work throttle valve.

The main advantage of having the Valvetronic system is the significantly lower fuel consumption (1.5 l/100 km on average) compared to conventional engines.

Interestingly, the N42 and N46 engines perfectly perceive the transition to work on liquefied gas. The main thing is the right choice and professional installation of LPG.

Well-maintained 4-cylinder engines are low maintenance. Having picked up a copy with a real mileage of less than 200,000 km, you will be satisfied with your choice.

Faults due to LPG

Despite the fact that motors perceive the transition to liquefied gas operation without consequences, an unprofessional approach to selection and installation leads to sad consequences. Valvetronic does not tolerate amateurism, the result of which is damage to the cylinder head and burnt valve seats. Before buying a car with LPG, you need to visit a car service and check the condition of the engine.

Models of the middle, upper class and sports

Engines of the M52 family debuted in 1994 on BMW 3 series E36 cars. M52 - further development reliable and powerful M50. The main difference is the use of an aluminum block, which reduced the weight by almost 20 kg. Together with lightweight connecting rods, chain tensioner and exhaust manifold the new engine has become lighter than its predecessor by almost 30 kg.

The M52 engine family is represented by engines with a working volume of 2.0, 2.5 and 2.8 liters, developing 150, 170 and 193 hp. respectively. S52 with 243 hp volume of 3.2 liters, installed on the M3 and intended for the market North America, is closely related to M52.

Released in 1998 year bmw 3 series E46, an updated M52TU engine appeared. It is distinguished by the use of a variable valve timing system for intake and exhaust valves (Double Vanos system). In the first engines, the valve timing was changed only on the intake shaft. Engine power has not changed, but performance at low and medium speeds has improved.

Operation and typical faults

Engines of the M52 family are classics of the genre. It enjoys a good reputation for being durable and reliable, but does not tolerate harsh use and careless maintenance.

Breakdown of the cylinder head gasket and cracks in the cylinder head

Inline six-cylinder engines are sensitive to overheating: the long head can burst. At best, it will break cylinder head gasket. Frequent problems with the cooling system pump and the radiator fan drive contribute to trouble. Ignoring the symptoms of overheating can lead to disastrous results when the most effective and cost-effective profitable way repair will be the acquisition of another motor in working order.

Camshaft Position Sensor Malfunctions

The defect is manifested by uneven operation of the engine and sluggish unwinding of the engine after warming up. Failure can also be accompanied by difficult starting - you have to turn the starter for a long time. Inexpensive analogues will cost less than 1,500 rubles, Siemens products are more expensive - about 3,000 rubles. Replacement is not difficult even for a non-specialized mechanic.

High oil consumption

In old age, the degree of wear of most engine elements increases. A considerable contribution to oil consumption is brought by exhausted valve stem seals.

Ignition coils

One coil for the M52 engine costs about 2000 rubles.

Application

Engines of the M52 family were installed both in small cars of the 3 and Z3 series, and in the flagship BMW 7 series.

Distributed injection fuel

Gasoline engines of the M54 series are one of the best inline sixes bmw. They got under the hood of many Bavarian models.

The R6 M54 debuted in 2000 in three versions: 2.2, 2.5 and 3.0. All variants received a variable valve timing system for intake and exhaust valves (Double Vanos).

Owners praise not only the pleasant sound and good performance of engines (especially 2.5 and 3.0), but also reliability. However, don't rely on fuel economy.

The M54 engine disappeared from the list of proposals in 2007, along with BMW convertible E46.

Operation and typical faults

Serious malfunctions are rare and most often due to very high mileage, careless maintenance and unprofessional repairs.

The only problem is over high flow oils. Losses occur as a result of oil waste and due to the specific design of the oil separator, which leads to clogging of the crankcase ventilation valve. As a result, excess pressure in the engine increases, which contributes to even higher oil losses.

Application

The N52 engine family debuted in 2004 with a 3-litre engine in the BMW 630i E63. In 2005, its modification appeared with a working volume of 2.5 liters. To save weight, the engine block is made of an aluminum-magnesium alloy. The Valvetronic valve stroke control system and the Double Vanos valve timing system are also used here. The engine that replaced in 2011 is a direct successor to the N52, but with a turbocharger and 4-cylinders - typical example downsizing.

Operation and typical faults

Noise of hydraulic lifters

The problem primarily concerns engines manufactured at the initial stage of production - before November 2008. Subsequent engines received a redesigned cylinder head.

Coolant pump failure

There are failures in the operation of the electric pump of the cooling system, leading to serious consequences. Replacement costs about 15,000 rubles.

Diesel engines

Short description:

Turbocharging

4-cylinder

16 valve

Common rail injection system

The power unit with the code designation M47 is a 2-liter diesel engine used from 1998 to 2007. It is interesting that two generations of 2-liter diesel engines are hidden under the M47 code: the first generation - until 2003 with a working volume of 1951 cm3, and since 2001 a new generation with a working volume of 1995 cm3. The first M47 was with a high-pressure fuel pump, and the second with a Bosch Common Rail injection system.

The 2-liter M47 can be found both in models marked "18", for example, the BMW 318d, and marked "20", for example, the BMW 320d. With the same working volume, they differ in equipment and developed power. M47 1951 cm3 was also used by the English Rover in the Land Rover Freelander, MG ZT and Rover 75.

Along with the increase in capacity, the engine received balance shafts. The turbocharger, instead of vacuum control, acquired a more accurate electric one. A good torque curve was obtained thanks to the use of variable intake manifold geometry: flaps regulate air flow depending on engine speed. Each version of the M47 has chain drive Timing, and in this series of engines, unlike the N47 receiver, it is placed in an easily accessible place - in front of the engine. All M47s have a dual mass flywheel, and the latest examples can be equipped with a DPF filter.

Operation and typical faults

The M47 engine is technically advanced and sometimes causes difficulties for mechanics with the correct conclusions when diagnosing. However, compared to the successor to the N47, it should be seen as a less problematic and more successful engine. Versions with power from 143 hp provide excellent performance, and at the same time quite economical. For example, a 163-horsepower 320d consumes an average of about 6.6 l / 100 km.

Destruction of the intake manifold flaps

This is a typical failure of many BMW diesel engines, including those with six cylinders. The dampers responsible for changing the geometry of the intake manifold can become loose and fly off the axles, hitting directly into the engine. This leads to damage to the cylinder head (destruction of the combustion chambers), the turbocharger, and sometimes the pistons.

Premature failure of the turbocharger

Longer oil change times are often blamed for low turbocharger life. To prolong its life, it is better to shorten the prescribed oil change intervals. Since the turbocharger is electrically controlled, not all turbine remanufacturers can adjust it correctly after repair. However, it is technically possible.

Pulley wear

The source of suspicious knocks from the engine is often a delaminated damper pulley, which is responsible for driving attachments. However, sometimes a dual-mass flywheel located on the other side of the engine makes a similar noise.

Application

Among similar turbodiesels of its age, the M47 excelled technically and in terms of performance. This is a very successful engine, although you should not count on the cheap cost of operation. He has whole line technical solutions that require high costs for service. However, the engine cannot be described as very problematic.

Alternative

Among diesel BMW engines, basically, large selection no, except perhaps for the 2-liter M47. The rest of the engines are much more powerful.

Turbocharging

4-cylinder

16 valve

Common rail injection system

Compact, mid-range and SUV models

In March 2007, BMW launched a new generation of two-liter N47 diesel engines on the market. The design of the engine has changed fundamentally: the cylinder block is made of aluminum alloy, which saved 17 kg, the timing drive was moved from the front of the engine to the rear - to the flywheel. Most of the engines in this series were equipped with a braking energy recovery system, the so-called Efficient Dynamics.

All N47 series engines from 163 hp have a piezoelectric Common Rail injection system with an operating pressure of 1800 - 2000 bar. More weak engines equipped with electromagnetic nozzles with a working pressure of 1600 bar. Since the new engine has more torque than the M47, the crankshaft had to be reinforced. Of particular interest are the 204-218 hp versions, which are supercharged sequentially with two different sizes of turbochargers. This is the most powerful 2-liter turbodiesel in the world. In 2013, the N47 appeared with a working volume of 1598 cm3 with a reduced pitch and cylinder diameter and a different block design. He received the designation 14d, and his power is 95 hp.

Operation and typical faults

Diesel N47, given the performance, is a very economical engine. Performance, minimal vibration and pleasant sound deserve high marks. The powerful torque available from low rpm means that even large and heavy vehicles such as the 520d and X3 will not experience any problems with dynamics. The BMW 520d F10, weighing over 1600 kg, is content with an average of just over 7 l/100 km, which is very good result. N47 in terms of fuel consumption is more economical than its predecessor M47.

Timing imperfection

Located in an inconvenient place for maintenance, the timing chain drive proved to be extremely unreliable. A poor-quality lower sprocket quickly wore out the teeth, which led to chain damage. Noise from worn parts could appear after 60,000 km. In extreme cases, it came to jumping the chain or breaking it. Theoretically, the manufacturer resolved the issue in 2010, but opinions about achieving a positive result are contradictory. There are cases when, after a warranty replacement of the timing chain, the alarming noise reappeared - approximately after 150,000 km.

intake manifold flaps

The problem is similar to the one that exists in the M47: the flaps become loose, fly off and fall into the engine, damaging it and the turbocharger.

Piezoelectric nozzles

They are used in high power engines. Nozzles of this type cannot be restored, therefore, in the event of a malfunction, the owner will face high costs. Under normal operating conditions, the nozzles confidently go more than 200,000 km.

Application

Since March 2007, the engine has gradually replaced its predecessor. In the new version of the “five”, a 2-liter biturbo replaced the 6-cylinder diesel 525d.

Common rail injection system

Turbo or biturbo

Models of the middle class and above, and SUVs

The M57 engine family with common rail injection system debuted in 1998, i.e. less than a year after the introduction of the first diesel engine with a CR system for stock car Alfa Romeo 156. The BMW diesel has received numerous engine of the year awards in its category. Other manufacturers also used this power unit: the 2.5-liter version of the M57D25 fell into Opel Omega, and a more powerful version in the Range Rover.

Diesel with the designation M57 has a cast iron block, 6 cylinders in a row and an aluminum head with two overhead camshafts. Power supply pump high pressure, fuel rail and nozzles - depending on the year of manufacture, electromagnetic or piezoelectric.

During the production process, its design changed several times: in later models, designated M57N and M57N2, the timing chain drives only one camshaft, and the moment is transmitted to the other camshaft through a gear reducer. Modifications with electrically controlled turbine blades, a new generation Common Rail injection system with higher operating pressure and a particulate filter were also introduced in succession. The top version M57TU2D30 has two turbochargers and 286 hp.

Operation and typical faults

The first versions of the M57 engine are considered not to be killed. There are cases when a BMW 5 Series with this engine drove 1,000,000 km without overhaul.

flaps in the intake manifold

More powerful versions of the M57 engine are equipped with a system for changing the length of the intake manifold. Weakening of the dampers and their "spanking" is the most common ailment of the M57. An experienced mechanic will determine the presence of a defect by ear. Many resort to the removal of dampers, but this is not recommended. The prevailing opinion of the majority that after the removal of the shutters the engine works the same way is not entirely accurate. The engine reacts worse to gas in the lower rpm range. The cost of restoration of dampers is from 5000 rubles and more.

M57N pulley damage

In the upgraded version of the engine with index N, the attachment drive pulley mounted on the crankshaft fails relatively quickly. This may cause damage to units such as the air conditioning compressor.

Common rail fuel injectors

In early versions of the engine, they were durable, but later, from about 2003, the resource was significantly reduced and amounted to just over 100,000 km. In older versions, Bosch solenoid injectors are remanufactured. In later ones, especially biturbo, only a replacement. The price of 12,000 rubles apiece is quite reasonable, especially since we are talking about a car of an expensive and prestigious brand.

Intake manifold rupture

Met only in the engines of the very first batches.

Application

The M57 engine is mounted longitudinally at the front, and the torque is transmitted to the rear wheels or two axles in xDrive versions, where the front wheels receive the necessary traction through cardan shaft.

Each engine has its own drawbacks, but in the M57 they are not too significant, and malfunctions can be detected and eliminated at the very beginning of their development. Six-cylinder BMW diesel guarantees sporty dynamics with reasonable fuel consumption. How older engine the more reliable it is. Recommended versions 184 and 218 hp

Alternative

The naturally aspirated 3.0-litre petrol engine also has excellent dynamic characteristics, is exceptionally reliable, but consumes 15% more fuel.

High end models and SUVs

The advanced N57 engine debuted in 2008. The new letter designation is fully justified, since the power unit was completely developed from scratch. Its block is made of aluminum, which is likely to affect its durability in the future. The common rail injection system operates at pressures up to 2000 bar. N57 is the first serial engine triple supercharged: this version of the engine, developing 381 hp, was designated N57S. After such a supercharged biturbo engine, you will not surprise anyone. N57 engines are very often combined with all-wheel drive. Only an 8-speed "automatic" is installed in a pair of the motor. All N57s have a particulate filter.

Operation and typical faults

chain rattle

This problem is becoming more and more acute, and BMW does not cover the costs in the post-warranty period. Long intervals between oil changes adversely affect the condition of the tensioner and the chain itself.

The appearance of soot

Owners report that the N57 engine is prone to carbon deposits in the intake ducts. In some cases, already at 70-80 thousand kilometers, it was necessary to disassemble the engine to clean it.

Application

Aluminum N57s are gradually replacing the old M57s. The engine is not used in cars of other brands.

The N57 is not an engine to save money on. It has great performance, but it costs a fortune to maintain.

Alternative

Such characteristics are provided only by the 4.4 Turbo V8 engine, designated N63.

Conclusion

General rule concerning engines BMW simple: all engines, both gasoline and diesel, are quite durable and have relatively little weaknesses. However, if a malfunction occurs, then it is necessary to prepare for the high costs of its elimination. You should avoid buying a cheap car with a dubious past. Such savings will quickly go sideways. It is also impossible to neglect the regular monitoring of the technical condition of the engine.

The year 2008 was marked by the release of another inline 6-cylinder N57 turbodiesel, which was supposed to replace everyone's favorite BMW M57. New engine used closed aluminum block cylinders with cast-iron liners and with an intercylinder distance of 91 mm, a forged crankshaft with a piston stroke of 90 mm is installed inside the block, the cylinder diameter is 84 mm, and the piston height is 47 mm. As a result, we have a working volume of 3 liters.

They covered the block with an aluminum cylinder head, which is slightly lower than that of the M57 predecessor. Twin-shaft head, 4 valves per cylinder, intake valves diameter 27.2 mm, exhaust valves 24.6 mm, valve stem diameter 5 mm. To ensure the safety of pedestrians and increase the distance between the engine and the hood, the timing drive was moved to back engine. The timing chain on the N57 is single-row and lasts longer than on the 4-cylinder counterpart N47. The chain resource exceeds 200 thousand km. The N57 uses a 3rd version common rail injection system, a CP 4.2 injection pump and, of course, a turbocharger with an intercooler is installed. The turbine here is a Garrett GTB2260VK with variable geometry that inflates to 1.65 bar.

This engine matches environmental standards Euro 5.

Like the M57, it uses a swirl flap intake manifold and an EGR exhaust gas recirculation system. The engine is controlled by a Bosch DDE7.3 ECU.

In September 2009, BMW 740d cars with the N57 TOP engine went on sale. It is equipped with a modified exhaust, piezo injectors and a two-stage turbocharging system, where the second stage has a variable geometry turbine and a boost pressure of 2.05 bar. Turbines here are BorgWarner K26 and BV40. Drives a Bosch DDE 7.31 motor.

Since 2011, the production of modified N57TU diesel engines began, which became a little more economical, received slightly modified combustion chambers, Garrett GTB2056VZK, solenoid injectors, and also began to comply environmental regulations Euro 6. The control unit here is Bosch DDE7.41. In 2012, the top version of this series was released - N57TU Super or N57S, which was developed based on the N57 TOP. It was distinguished by a reinforced cylinder block, new pistons for a compression ratio of 16, a different crankshaft, an improved cylinder head cooling system, the strength of which was also increased. Inlet and exhaust valves(29.2/26 mm), the camshafts have not changed. There is also a new short intake system, piezo injectors and a modified fuel system with increased injection pressure, and the exhaust complies with Euro-6 standards. The N57S uses a Bosch DDE7.31 ECU. The most important thing that distinguishes the N57S is three-stage supercharging: there are two BorgWarner BV45 and one B2 turbines, which allow you to get 381 hp. at 4000-4400 rpm and a torque of 740 Nm at 2000-3000 rpm.

In parallel with the N57, a related 4-cylinder diesel N47 was produced, which is a smaller copy of the N57 and, in addition to the absence of two cylinders, differs mainly in turbines, intake and exhaust.

Starting in 2015, the N57 is gradually being replaced by the newer B57 diesels.

BMW N57D30 engine modifications

1. N57D30O0 (2008 - 2014) - the very first N57 diesel. Its power is 245 hp. at 4000 rpm, torque 540 Nm at 1750-3000 rpm. They put this motor on the BMW 530d F10 and F07, 730d F01, X5 E70 and X6 E71. For the BMW 325d E90, the torque has been reduced to 520 Nm. 2. N57D30U0 (2010 - 2013) - the weakest modification of the N57 with a Garrett GTB2260VK turbine. Engine power 204 hp at 4000 rpm, torque 450 Nm at 1750-2500 rpm. This motor is found on the BMW 325d E90 and 525d F10. This internal combustion engine was replaced with a 4-cylinder N47.3. N57D30T0 (2009 - 2014) - the most powerful engine N57, which replaced the M57TU2 TOP. It develops 306 hp. at 4400 rpm, torque 600 Nm at 1500-2500 rpm. They put N57 TOP on BMW X6 E71, X5 E70 and 740d F01. For the 535d F10 and 535d GT F07 vehicles, power has been reduced to 299 hp4. N57D30O1 (2011 - present) - an engine from the N57TU series, which replaced the N57D30O0. Power 258 hp at 4000 rpm, torque 560 Nm at 1500-3000 rpm. There is such a modification on the BMW 530d F10 / F07, 730d F01, 330d GT F34, 330d F30, 430d F32, X3 F25, X4 F26, X5 F15 and X6 F16. 5. N57D30T1 / N57TU (2011 - present) - replacement for the N57D30T0 model. Power reached 313 hp. at 4400 rpm, and a torque of 630 Nm at 1500-2500 rpm. This motor pleases the owners of 335d F30, 335d GT F34, 435d F32, 535d F10, 535d GT F07, 640d F13, 740d F01, X3 F25, X4 F26, X5 F15 and X6 F16. 6. N57D30S1 (2012 - present) - N57 engine with three turbines, which allow you to get 381 hp. at 4000-4400 rpm and a torque of 740 Nm at 2000-3000 rpm. Such an engine can be found in the BMW M550d F10, 750d F01, as well as the X5 F15 / E70, X6 F16 / E71 with the designation M50d.

Problems and disadvantages of BMW N57 engines

1. Swirl flaps. Unlike the M series, here they cannot fly into the engine, but they are able to coke so much that they stop moving, as a result of which the car will start to run unevenly and produce errors. The reason for this is the EGR valve, which needs to be periodically cleaned or programmatically removed, because often already at 100 thousand km the collector can be completely clogged with dirt. 2. Noises, extraneous sounds. As on the N47, the crankshaft damper fails here early (after about 100 thousand km) and needs to be replaced. After 200 thousand km, an extraneous sound from the back of the engine indicates the need to pay attention to the timing chain, it may need to be replaced.

The turbine resource is normal and is approximately 200 thousand km or more. In order for the engine to serve as long and trouble-free as possible, you should not delay changing the oil and use only high-quality engine oils, as well as regularly service your engine and pour good fuel. In this case, the resource N57 can greatly exceed 300 thousand km.

BMW N57 engine tuning

Chip tuning

Simple versions of the engine with one turbine of the N57 series (204 hp and 245 hp) with one block firmware are tuned up to 300 hp, and with a downpipe up to 320 hp. N57TU engines give 10-15 hp. more. These are the most profitable internal combustion engines for tuning. The power of the N57 diesel with two turbines can be raised to 360+ hp. firmware and downpipe. Models with N57TU allow you to get about 380 hp. with the same set.

The most evil and perfect diesel engine N57S with firmware and downpipe can show 440 hp. and 840 Nm.

History of BMW diesel engines

Mechanical components and parts of a BMW diesel engine

Strong foundation

Even today, mechanical components and parts form the basis of any engine operating on the Diesel principle. The task is to convert the chemical energy present in the fuel into motion using a thermodynamic process. As a result of the combustion of the fuel-air mixture, the piston receives acceleration. This rectilinear up and down movement of the piston is converted by the crank mechanism into rotational movement. The block crankcase limits the combustion chamber and it also contains crank mechanism. In the cylinder head, gas exchange is exclusively controlled by valves and channels. The physical principle of operation does not differ from gasoline engine. The main difference from a gasoline engine operating on the Otto principle is the combustion process. In a diesel engine, fuel is injected directly into the combustion chamber (internal mixture formation). Due to the high degree of compression fuel-air mixture becomes very hot and its temperature reaches the ignition temperature. Combustion starts without the aid of a spark plug (self-ignition). Rudolf Diesel and his engine Rudolf Diesel patented his first self-ignition internal combustion engine in 1892. This large, slow-running engine was originally conceived for stationary use only. The labor-intensive design of the engine, the complex injection system resulted in a high production cost. The first simple engines were not very comfortable and high-speed units. The harsh combustion process made the diesel engine, especially when cold, quite loud (due to knocking). Compared to a gasoline engine, it had poor power density and dynamics, and, in addition, a low liter power. Only after using trucks and a number of improvements in the properties of materials and the manufacturing process managed to miniaturize it. Although the first car with a diesel engine was made already in 1936, it was necessary to wait until the 70s, until the diesel engine began to be used as a real basis for a car drive. The breakthrough came in the 80s when it was finally fully developed. The diesel engine has become an alternative to gasoline. At this time, BMW decided to use it on their production models cars due to the improvement of its dynamics and acoustics.

BMW has been producing cars since 1929, and since then the demands on engines have been constantly increasing. BMW has always been innovative and technical details who were unparalleled in the world. This tradition continues in the field of diesel engines. The era of diesel engines began with the first production BMW engine in 1963.

First introduced on the E28, the M21D24 was turbocharged on the 524td and had a displacement of 2.4 liters. Its prototype was the M20 gasoline 6-cylinder engine, and it developed a power of 85 kW / 115 hp. With. In this case, both engines could be assembled on the same conveyor. Dynamic performance with a top speed of 180 km/h and acceleration from 0 to 100 km/h in 13.5 seconds set new standards for diesel vehicle dynamics at the time. Therefore, the 524td received the title of "Sport Diesel". Since September 1985, they began to assemble the M21, an atmospheric diesel engine. This made it possible to offer a cheaper "base engine". This engine on the 324d (E30) has made a name for itself as the smoothest running self-ignition engine. BMW becomes the first car manufacturer to offer an electronic engine management system, the so-called Digital Diesel Elektronik (DDE). Electronics adjust faster and more accurately than mechanical control

• operation of the exhaust system
• fuel consumption
• acoustics
• running quality

BMW 525tds with M51 engine

engine Introduction of the all-new M51D25 engine, turbo-cooled with 105 kW/143 hp. s, debuting as the most powerful diesel engine in its class. At the same time, he replaced the M21 engine and received a completely new block crankcase. The engine was offered in 115 hp variants. With. and 143 l. With. Thanks to the V-shaped main combustion chamber in the piston, it is possible to improve exhaust emissions and smoke at full load. The M41 engine was the first 4-cylinder diesel engine in a BMW car. It was developed on the basis of the M51D25 engine and had 56% of common parts with it, only 14% of the parts had to be created anew. Innovations included, for example, a hollow cast camshaft on 5 bearings, as well as a soundproofed cylinder head. This engine was installed in various models E36 series. BMW 320d with M47 engine The M47 direct injection engine, created by BMW in 1998, was the most powerful 4-cylinder diesel engine. 100 kW from 2 liters of displacement became the peak value, which until then was common only for gasoline engines. This corresponded to a liter power of 50 kW or 68 hp. With. BMW 320d with M47 engineMotorsport provides the best proof of the power and reliability of new diesel engines. And BMW is celebrating a historic success at the Nürburgring. The diesel-powered 320d in 1998 wins the 24-hour race for the first time in motorsport history. And not only because it needs to fill up less often, but also because BMW has the best lap times.

BMW 740d with M67 engine

The first V8 diesel engine, the M67D40 engine, with a displacement of 4 liters, is introduced on the E38 model and has a power of 175 kW. The world's most powerful passenger car diesel engine at the time, with common rail injection and 2 exhaust gas turbochargers, proves BMW's technical prestige. The engine has a ductile graphite gray iron (GGV) crankcase, an aluminum cylinder head and a two-piece oil pan. BMW 530 with M57 engineThe M47TU engine with the second generation common-rail injection system and DDE5 control system achieved an output of 110 kW/150 hp. With. A further upgrade of the M51D25 engine is the M57D30 engine, it has a gray cast iron crankcase, light alloy cylinder head with 4 valves per cylinder. M57 was the world's first diesel inline 6-cylinder engine for passenger cars, equipped with a promising common rail injection system. This new sophisticated electronically controlled injection system perfectly fulfills the requirement of high and constant fuel pressure throughout the entire injection time. At any time, a noticeable reduction in fuel consumption is provided compared to engines with swirl-chamber mixture formation, high driving performance and flawless operation of the engine in extreme conditions.

BMW X5 3.0d with M57TU TOP engine

The production of the most powerful diesel engine - M57TU TOP with 2-stage turbocharging (E60 and E61) has begun. For 2-stage turbocharging, 1 small and 1 large turbochargers are used. The diesel engine on the 535d delivers 40 kW/54 hp. With. larger than an engine of the same displacement (3.0 liters) on the 530d. Power is 200 kW / 272 hp. With. The maximum torque of 560 Nm is reached at 2000 rpm. This outstanding engine brought Luc Alphand victory in the Paris-Dakar Rally not only in the diesel car class, but also placed him in fourth place in the overall classification.

BMW 730d with M57TU2 engine

On the E65 model, the M57TU2 engine is installed. Along with the increase in power and torque, the following technical features should be noted:

• less weight due to aluminum block crankcase;
• 3rd generation Common-Rail injection system with piezo injectors and a pressure of 1600 bar;
• compliance with EURO 4 emission standards and standard diesel particulate filter;
• Optimized electric boost pressure regulator for exhaust turbocharger with variable turbine geometry.

BMW 745d with M67TU engine

The M67 engine on the E65 model in the same 2005 underwent a significant upgrade. Its goal was a noticeable improvement in dynamic performance by increasing power and reducing weight. Power has been increased by as much as 16% while reducing engine weight by 14%, and that's without increasing fuel consumption.

This was achieved, among other things, thanks to a new lightweight aluminum crankcase, as well as an increase in displacement to 4.4 liters.

History of diesel engines

Historical facts from world bmw, bmw history AG of her unit models and much more.

They are one of the best in the line of BMW powertrains. The M57 series has been repeatedly awarded at international competitions. The cylinder block was produced from gray cast iron, and later cast from aluminum alloy and had dry cylinder liners, which reduced the overall weight. The cylinder head is cast from aluminium. The crankshaft is designed with 12 counterweights. Drive two camshafts comes from a single row roller chain. There are 24 valves of the gas distribution mechanism, 4 per cylinder. Pressing the valve is not direct, but through a lever. The pistons are made with a conical recess to improve the mixing of the working mixture. The camber angle of the connecting rod journals of the crankshaft is 120 degrees. The movement of the masses is balanced in such a way that the running engine is almost stationary. The injection pump is driven by a chain. The engine was produced with two cylinder capacities, 2.5 and 3 liters. All engine modifications are equipped with a turbocharger, and some of them with two turbochargers. Turbochargers have electronic adjustment impeller geometry. The engine has been equipped fuel system direct injection Common rail with pressure accumulator. The intercooler helps increase the amount of air supplied. Engine oil level control electronic. The use of a piezo injector in the injection ensures accurate fuel delivery, reduced fuel consumption and increased environmental friendliness exhaust gases. The average weight of the engine is 132 kg.

Problems

The engine is very demanding diesel fuel. The use of low-quality diesel fuel of dubious origin leads to premature failure of the injectors of the injection system and the fuel pressure regulator. The injection pump has become more reliable and does not require frequent intervention, unlike the M51 series engines. Turbines are ready to blow for a very long time, subject to use quality oil and a good exhaust system. Before changing the oil, it is worth purchasing an oil filter housing cover. It is plastic and most often cracks when replacing the filter element. Like its predecessor, the M57 engine is sensitive to overheating, which causes a lot of trouble and expensive repairs. A common problem for BMW engines is the gas recirculation valve. Rarely do air flow meters fail. Electrovacuum hydromounts of the motor die by 200 thousand km. run. A tricky problem that immediately pushes to replace the turbine is the oil sweating of the pipes from the turbine to the intercooler, or from the crankcase ventilation valve to the turbine. The oil separator does not perform its function of cleaning crankcase gases. Permanent oil vapors settle on the nozzles and appear through loose connections and worn flanges. To ensure that the air supplied is clean, the crankcase gas cleaning roller is changed at each oil change. It does a better job of cleaning oil than a cyclone, which you must remember to flush. In general, the engine before overhaul at timely service able to calmly reach 500 thousand km.

The same question is often asked on the topic "what about diesels in BMW?", or "what kind of diesel should I buy"?
Instead of an answer, accept a short essay on the topic "diesel in BMW".

Diesel engine has more high efficiency in the mode of full return and noticeably higher - in the mode of partial loads and idling. The principles of its operation interfere with the gasoline engine - the presence of a throttle, the formation of a mixture outside the combustion chamber, the inability to work on lean mixtures. Partial load mode for him is uncomfortable and extremely harmful. In this sense, the advantage of the diesel engine is absolute.

- its average temperature is noticeably lower, and in the mode of partial loads and idling, a modern diesel engine may not even warm up to the nominal operating temperature. Thanks to these features, the diesel engine is almost not afraid of traffic jams, and even more so - idling: it’s not so scary to stop it with an everyday plug start-stop. The heat dissipation of a diesel (turbodiesel) is not only lower, but also "smarter" - the presence of a turbine is almost a guarantee that in a cork crush you do not load the engine with excessive power - on low revs she barely works.

In the dry residue, in terms of the load on the oil, which, by the way, in diesel engine always more by about 20% than in a gasoline counterpart of a similar displacement, a diesel engine qualitatively outperforms a gasoline engine.

It is also possible to recalculate, for example, the power dissipated on average per volume of oil, etc. - in all this, the diesel internal combustion engine wins with a margin and "for a clear advantage." And if we also recall the "traditionalist" conservative manners and fads to change the oil in a diesel engine every 7-10 thousand kilometers (well, we have "dirty diesel fuel" - and advertising is blatantly lying about EURO5, and the oil is already " black" is), then the diesel engine, in terms of the expected resource, is almost eternal even under conditions Russian exploitation. Let's add here a few more possible factors that characterize the likely favorable conditions for the movement of such cars - diesel engines are often bought by those who travel far and at a high average speed ...

Total: a modern diesel engine is significantly different from a modern gasoline engine in terms of the expected resource precisely due to a successful combination of technological features. I'll tell you how much below.

Now questions that are often asked on this topic:

How modern are BMW diesel engines?
BMW makes some of the highest quality and most modern diesels - they are economical, high-torque and reliable. In the most modern versions, they are also very quiet, which can not be said about most competitors. For the past 20 years, BMW has been doing nothing but turning its successful gasoline engines "into diesels", trying to get "ecology and economy" out of them through monstrous technological tricks. The results, if you do not take into account the victory in the "engine of the year" competition, are actually deplorable. But in the design of a diesel engine, it is deprived of a huge amount of technological and environmental debris: VANOS, Valvetronic, a controlled thermostat, and so on. Diesels are just improving in technology, with minimal environmental troubles. At the time of 2012, in the battle of gasoline / diesel, diesel unconditionally wins.

What can be said about specific models?
M21 - never seen.
M51 - I saw a couple of times, an ordinary tractor.
M57 is a great option for X5. On a sedan, it seems strange to me, although this is a matter of taste.
The N57 is a quiet, almost "gasoline" diesel engine. If not for the short rev range, it would be difficult to distinguish from a gasoline turbo engine.
N47 / M47 - loud, but very economical motors. There are seemingly already solved problems with the timing, which are not at all easy to solve if you still encounter them. In any case, this is a choice for savings.

Are there any statistics?
Complete measurement and inspection diesel internal combustion engines requires removal of the injectors. This is not a quick or cheap procedure. I do not have measurement statistics for these motors, and there are few requests for them in principle. The reasons are explained in the next paragraph.

Resource?
Even with unsuccessful "recommended" oil and equally unsuccessful analogues of this oil, you run the risk of leaving without problems 200-250 thousand km and even more. And this is practically without oil consumption and on almost any of the BMW diesels. With the condition, of course, that the motor did not overheat and was operated normally. Subsequently, problems will arise about the same as those of gasoline counterparts. The processes in the CPG there are completely similar, they just happen more slowly and the threshold of visibility, thus, is pushed back by guaranteed 5-7 years of completely comfortable operation. The greater your annual mileage and the higher the average speed, the further the start of problems with oil consumption is pushed back. What the owner of a gasoline engine should worry about already on a run of 40-60 thousand (!), His diesel counterpart may not be disturbed at all during the entire time of owning a car.

Problems?
I consider the fuel equipment to be the main problem - it is really expensive for a diesel engine. One gas station "with sand" and repair can unpleasantly surprise you with its cost. However, if you use "regular" oil, problems will definitely appear in the above interval, it's just that most will not even consider them problems. The vast majority of owners of gasoline BMWs show no signs of anxiety at all up to an oil consumption of 1 liter per 1000 km.
In the case of a diesel engine, which during the first years of operation, most likely, will not consume oil at all, the owner will not be afraid of even 1, 2 or even 3 liters per 10,000 km. Most likely, the logic “well, thanks for holding out for 5 years, and now you can forgive” will work, instead of the reasonable logic “I didn’t eat at all, why did I start now?”.

The Bavarian concern completes its crossovers and sedans, station wagons with diesel power units. The range of these BMW engines is one of the best in the world. One of the main advantages is the reliability of the unit, excellent wear resistance of the catch. But as practice shows, the repair of diesel BMWs is not uncommon. Among the vulnerable parts of the engine are liners and piston rings, which rarely withstand more than 300 thousand km. Timely diagnostics will allow postponing engine repairs for a long time, because not only mileage affects the condition of the engine, but also the specifics of operation, timely maintenance and the quality of the oil used.
