Today, the popularity of Toyota Camry for Russian car enthusiasts is undeniable. It has been a sales leader for more than three decades. It is understandable, comfortable and roomy sedan with a price like a budget Korean in the most best configuration, makes such a purchase very attractive. And the 2.4-liter 2AZ-FE engine, released at the turn of the century, economical and not so boosted, made it possible to get closer to business class.

Engine Features

The cheap and technologically advanced 2AZ-FE has an open cooling jacket and is made of pressurized aluminum alloys. The engine is equipped with a chain drive, the intake camshaft is equipped VVT-i system responsible for timely change phases The intake manifold is made of plastic and is located at the rear of the engine, which protects it from severe deformation in accidents. Plastic gears significantly reduce the weight of the motor balance shaft coupled with a plastic intake manifold.

The FE engine oil pump has a separate chain drive, which allows it to instantly create the desired pressure upon startup.

Such features of the 2AZ-FE engine, with its low power, help to equalize traction characteristics and economical consumption fuel - about 11.5 liters in the urban cycle.

Typical malfunctions of the power unit

The following factors indicate that the 2AZ-FE engine will soon fail:

1. Floating idle speed followed by stopping the engine.
2. Transient modes with characteristic power dips.
3. Deteriorating startup with multiple attempts.
4. Appearance in expansion tank exhaust smell.
5. Antifreeze leak detection under the intake manifold.
6. Curvature of the landing cylinder head plane due to stretching of the fastening bolts.

The reasons for all these consequences are the exhaustion of the service life of consumables, early malfunctions of components and parts of the 2AZ series engine and an offensive design miscalculation by Toyota engineers. We list the most typical of them:

1. Sprocket production intake camshaft(VVT-i mechanism drive).
2. Failure of the coolant pump.
3. Failure of the generator overrunning clutch when its service life is reached.
4. Occurrence of rings and wear of pistons.
5. Resource development piston rings and valve stem seals.
6. Design miscalculation by engineers - thin cylinder head mounting bolts Toyota Camry and, as a consequence, their stretching and warping of the head plane.

If the first five reasons are resource development various nodes and FE engine parts, which is quite acceptable and understandable, then the sixth reason requires expensive repairs engine.

Block head repair

After establishing the cause, we partially disassemble the engine: remove the pulleys, valve cover, disconnect the intake and exhaust manifolds. We disassemble the gas distribution mechanism together with its drive. The camshafts show an emulsion (a mixture of antifreeze and oil) formed as a result of the bolts being pulled out. Unscrew the bolts securing the head of the 2AZ-FE engine and remove the head from the block. Checking the plane of fit. If it fails, then we send it to the workshop, where the part is leveled on special grinding machines.

After restoring the cylinder head geometry, there are two ways to improve the cylinder head mounting. The first is to drill holes, cut threads into them and screw in the studs on which the head will be attached; in this case, the nuts are installed with engravers for reliability. The second is to put repair kit, which was released by Toyota after admitting its design flaw.

It consists of threaded bushings with longer threads, and, imagine, after installing the kit, the defect no longer appeared. Then, for Toyota Camry produced after 2004, the threads in the cylinder head were lengthened by 6 mm, and “heads falling off” no longer occurred.

Let's return to our engine repair - after restoring the mounting, we wash the cylinder head, carefully grind the valves and replace them valve stem seals. We put the head in its place in the 2AZ-FE engine with a new gasket and tighten the fastening to the torque specified in the instructions. Camshafts insert into the head and tighten seats, after which we assemble the gas distribution mechanism. We connect the intake and exhaust manifolds to the head, and install the valve cover.

As for the motor resource Toyota engine Camry 2.4, then dealers promise that the car will easily withstand 400 thousand kilometers, but the exact mileage before major repairs is still unknown.

Conclusion

Toyota Camry is very reliable car and after engine repair it will last for a long time. Everything depends not only on the car, but to a greater extent on the personal qualities of the owner: both on driving style and on the degree of car care.

This car, with its elegance, reliability, and efficiency, won the hearts of car enthusiasts in many countries around the world, including the Russian Federation and the CIS. Toyota Camry occupies an intermediate place between vehicles middle and business classes.

IN various configurations power unit can be installed with a working volume from 2 to 3.5 liters. Many drivers, both those who already own this car and potential car buyers, will be interested in learning more about specifications car and its engine, fuel consumption in various modes movement, engine life.

The power units of this model have performed well, as evidenced by reviews from experts and car owners.

The engine design is high-tech; high-pressure aluminum alloy is used to manufacture the main components.

For drive camshaft a chain is used, and the shaft itself is equipped with a VVT-i system, which is designed to change phases. Plastic gears in the drive, polymers for intake manifold made the engine lighter.

Two-liter engine

The seventh generation Camry, until 2014, was equipped with the XV50 engine, later it was replaced by the more improved 6AP-FSE. The working volume for them is the same and equal to 2.0 liters. The upgraded engine received distributed direct injection. The engine power was 147 hp. s., then it was possible to increase it by 3 horses. Timing chain drive, 4-way step automatic A six-speed automatic transmission was replaced.

The service life of the engines is at least 300 thousand km, and with competent, timely and high-quality maintenance, more than 450 thousand km.

Camry V40 with 2.4-liter engine

The end of the last century was marked by the appearance of the V40 2.4-liter 2AZ-FE engine, its design did not belong to highly accelerated units, it was economical engine, which made it possible to bring the car closer to business class.

Important! The motor has a separate chain drive oil pump, this ensured an instant supply of lubricant to the rubbing pairs.

Fuel consumption Toyota car A Camry with such a “heart”, when traveling in the urban cycle, is within 11–12 liters per hundred km. The service life is at least 300,000 km.

Engine 2.5 l

In 2012, a 2AP-FE engine with a displacement of 2.5 liters was designed and launched into production. The engine has four cylinders, which are arranged in one row. It is still considered by experts to be the most successful design in terms of dynamic performance and fuel consumption. Competent service, use of quality Supplies allow the owner to drive 500 thousand kilometers or more without much stress. The cylinder block is cast from aluminum, in which there are cast iron liners.

Main disadvantage motor, which is indicated in the description of the machine, the power unit is not repairable.

Engine 3.5 l

The company's designers managed to achieve high reliability, manufacturability, and simplicity of power units that are not equipped with complex systems to reduce harmful emissions into the atmosphere. A working volume of 3.5 liters allows you to produce almost 250 horses, and after the 2GR modernization it is already more than 270 hp. With.

The cylinder block is cast from aluminum, in which cast iron liners are installed. The block design is V-shaped and has six cylinders. Engine specialists tune it and get almost 400 horses.

The timing mechanism is driven by a chain, which without special problems serves 200 thousand km or more mileage. The engine life is about 450 thousand km.

Toyota Camry is still one of the best-selling car brands in the world, in its own class. This is largely due to reliable, economical power units.

The first generation of the Toyota Camry was introduced in Japan in 1982, and exports to the USA and Europe soon began. Front wheel drive model was produced with sedan and hatchback bodies and was equipped gasoline engines 1.8 and 2.0, as well as a two-liter turbodiesel. In the Japanese market the car was also sold as .

2nd generation (V20), 1986–1992

Appeared in 1986 Camry second generations. It was produced at factories in Japan, the USA and Australia with sedan and station wagon bodies. The range of power units included engines of 1.8 and 2.0 liters, as well as a 2.5-liter V6 engine, their power ranging from 82 to 160 hp. With.

3rd generation (V30, XV10), 1990–1996

The third generation Toyota Camry with the factory designation V30, which debuted in 1990, was intended only for Japanese market. The export version of the XV10 was similar in design, but it was larger, heavier and had a different design, and in Japan such a car was sold under named after Toyota Scepter.

The “Japanese” Camry had versions with sedan and hardtop bodies (sedan without a central pillar). The car was equipped four-cylinder engines 1.8, 2.0, 2.2, as well as V-shaped “sixes” with a volume of 2 and 3 liters. There was also an all-wheel drive version in the range.

Introduced in 1991, the “American” version of the model was offered in sedan, station wagon and coupe body styles. Basic version The Camry was equipped with a 2.2-liter engine (130 hp), and more expensive versions were equipped with V6 3.0 engines with a power of 185–190 hp.

4th generation (V40, XV20), 1994–2001

In the fourth generation, the division into Japanese and export versions of the model was maintained.

Toyota Camry for local market with the index V40 began to be produced in Japan in 1994. The car was offered only with a sedan body, but as before it had a platform model. The cars were equipped with 1.8 and 2.0 petrol engines, as well as a 2.2-liter turbodiesel. All-wheel drive transmission was available in combination with 2 and 2.2 liter engines.

The export Camry XV20 model of 1996 was sold, including on the Russian market, in my homeland I was known under the names Toyota Camry Gracia. Technical part has not undergone any changes compared to cars previous generation: 2.2 and V6 3.0 engines with 133 and 192 hp. With. accordingly. In the late 1990s, coupes and convertibles began being offered to American buyers.

5th generation (XV30), 2001–2006

The fifth generation Toyota Camry sedan, well known in Russia, was produced from 2001 to 2006 only with a sedan body. We sold cars with engines 2.4 (152 hp) and V6 3.0 (186 hp), paired with less powerful motor a four-speed automatic was an option, and in the second case it was included in standard equipment. In other markets, such as the American one, a version with a 3.3-liter power unit was also offered, and in Japan Toyota Camry was sold only with a 2.4-liter engine and an automatic transmission, but it could have four-wheel drive. Sales of this model in Western Europe were discontinued in 2004.

6th generation (XV40), 2006–2011

The sixth generation of the model was introduced in 2006, and in 2007, the assembly of Camry sedans began at a plant near St. Petersburg. Basic version for Russian market was equipped with a 2.4-liter engine (167 hp) paired with five-speed gearboxes transmissions, manual or automatic. Have more expensive option there was a V-shaped “six” with a volume of 3.5 liters (277 hp) and a six-speed automatic transmission transmission As a result of restyling 2009 Toyota of the Year Camry has received a slightly updated appearance.

In other markets, a version with a 2.5-liter engine with a capacity of 169–181 hp was also offered. With. and option with all-wheel drive transmission. Another modification - Toyota Camry Hybrid with a 188-horsepower hybrid power plant, the electromechanical part of which was borrowed from "", and gasoline engine had a volume of 2.4 liters. In China and the countries of Southeast Asia, a slightly different model was sold under the name Camry - a larger sedan created on the same platform.

The legendary Toyota Camry was equipped at different times various types motors. All engines had, depending on the volume, similar characteristics, but in terms of reliability they had their own characteristics. One of the most common motors supplied to domestic market, became Camry 2 - engine size. This engine is not the most positive side was quite well known to domestic repairmen in the past, but its new reincarnation in last body partly trying to rectify the situation.

Why two-liter?

The technical characteristics of the Toyota Camry-2 are quite simple for this class (in Russia, the model is considered the entry-level model in the business class and has the index D). Equipping the Camry with a 2-liter engine was caused by purely practical considerations - it erupted economic crisis, the ruble collapsed, and the solvency of citizens collapsed along with it. And although the model did not lose leadership positions in the classroom, sales dropped noticeably, so marketers had to urgently look for options to get out of the situation.

And the solution turned out to be installing a new engine. An engine with a similar displacement was familiar to owners of the Camry in the V30 body, but that engine had several main differences and fewer horses. Also new unit has many technical and design differences compared to its predecessor.

Description of the power unit

In general, the description of the motor must begin with the internal filling. Like its other brothers, the 2.0 unit is equipped with a timing chain. This mechanism is considered more reliable than a belt drive; its second advantage is its service life, which averages 200,000 kilometers.

Also, as an environmental addition, the engine has an improved neutral catalyst that filters out soot and other deposits in accordance with Euro 6 standards. Also, in comparison with other options, 2.0 is equipped with an improved piston group, which allows, as a result of flashing, to obtain noticeably more power than stated.

Since the nameplate power is set to 149 Horse power, sum transport tax in any region of the country will be small compared to cars of a similar class.

The 2.0 engine is equipped with a phase change system, which allows optimal distribution of traction while driving. low revs. Not all cylinders can carry out work, but with an increase, all are connected to it. Compared to its competitors, 2.0 has a fairly modest gasoline consumption, consuming mixed cycle about 10 liters (according to the manufacturer, about 8 liters, but measurements are carried out in ideal “greenhouse” conditions, which are quite difficult to achieve in practice).

Disadvantages of the unit

However, like any technically complex unit, these engines are not without some disadvantages. It is unknown for what reason, but the manufacturer has reduced the service life and replacement of some components (most likely due to lower volume), which affects the passage technical inspection big expenses. The main disadvantage is the insufficient level of acceleration dynamics for this class. How much is it?

The car accelerates to the “cherished” hundred in more than 10 seconds, which is enough in city traffic, but for confident overtaking on the highway this is not an outstanding result.

Bottom line

This engine is a combination of relatively high reliability, maintainability and low consumption fuel, which will be very pleasant for practical car enthusiasts without racing habits.

Engine Toyota Camry 2.5 liters of the 2AR-FE series began to be installed on Camry after 2008. IN different modifications the power unit produces from 154 to 181 hp. Today in our country, dealers offer Camry 2.5 with a power of 181 hp. Read more about this motor read further.

Camry 2.5 engine design

Inline 4 cylinder 16 valve atmospheric unit It has aluminum block cylinders and timing chain drive. For ease of maintenance in the cylinder head, the camshaft bearing housing is made separately. There are also hydraulic compensators. The engine has a variable valve timing system on both shafts. Cast iron sleeves are fused into the block material, and their special uneven outer surface contributes to the most durable connection and improved heat dissipation. Unfortunately major renovation motor with boring or liners is not provided. That is, after the allotted service life, or loss of block geometry (due to engine overheating), the cylinder block can be thrown into the trash.

The VVT-i system (DVVT - Dual Variable Valve Timing) allows you to change the valve timing within 50° for intake and 40° for exhaust, which allows you to make the most efficient use of the resources of the Toyota Camry 2.5 liter engine. The EFI engine management system includes distributed, sequential fuel injection, throttle valve With electronically controlled. What is interesting is that the control of engine operating modes takes into account the presence traction control system and takes over some of the functions of the stabilization system and cruise control.

A feature of the engine can be considered the displacement of the crankshaft relative to the piston axis to reduce the load on piston group. The crankshaft has 8 counterweights on the cheeks, reduced width journals and traditional separate main bearing caps. From crankshaft using a gear drive, a balancing mechanism with polymer gears is driven. Look at the picture below.

Toyota Camry 2.5 cylinder head

The cylinder head is made of aluminum alloy and is made of -
1 — bearing cap, 2 — camshaft housing, 3 — cylinder head, 4 — spark plug hole, 5 — Exhaust valve, 6 — inlet valve. look at the picture above.

Camry camshafts are installed in a separate housing, which is then mounted on the cylinder head - this simplifies the design and processing technology of the cylinder head itself. The valve drive uses hydraulic compensators valve clearances and roller tappets/rockers.

Camry 2.5 engine timing drive

The gas distribution mechanism is driven single row chain(step 9.525 mm). Hydraulic chain tensioner with locking mechanism is installed with inside covers, but has access through the service hole. The chain is lubricated using a separate oil nozzle. The Toyota Camry 2.5 timing drive diagram is shown below.

Timing chain drive and consists of the following elements.
1 - intake camshaft sprocket
2 - damper
3 - intake camshaft
4 - exhaust camshaft
5 - rocker
6 — tensioner shoe
7 — chain tensioner
8 — exhaust camshaft sprocket
9 - damper, 10 - inlet valve
11 — exhaust valve
12 — hydraulic compensator
13 - chain.

There is actually another small chain that transmits torque from the crankshaft sprocket to the oil pump sprocket.
