Russian motorists were looking forward to the appearance of Renault Logan on the domestic market. The sedan became available for purchase in 2005, and two years later another modification of the car went on sale - a hatchback. If the appearance of Logan in dealerships was known in advance, as well as the debut of a car on Russian roads, then only a small part of the drivers knew about another family member - Renault Sandero Stepway. Nevertheless, the novelty was enthusiastically accepted by the Russian public of lovers of inexpensive and high-quality cars.
Formally, the Sandero Stepway is not part of the Logan family, but the model was designed specifically on the platform of the aforementioned car. The novelty appeared on the market in 2009, and in the shortest possible time won the love and trust of many fans of the Renault auto group. The appearance of an SUV, high ground clearance, an attractive set of options and a variety of trim levels - the manufacturer endowed the model with all these qualities and characteristics. Of course, a hardy power plant played a significant role in popularizing the hatchback. Next, we will tell you what is the resource of the Renault Sandero Stepway engine in practice.
What engine is worth?
Renault Sandero Stepway is an incredibly popular hatchback in Latin America. At first, the car was assembled in Brazil, and after that the first copy of the car rolled off the assembly line of a car factory in Argentina. Some time later, the Moscow Avtoframos plant also launched the assembly of the model. For a long time, the hatchback only came with a manual transmission. The fact that there was no modification with two pedals somewhat underestimated the sales of the car. But already in 2011, a version with an automatic transmission appeared, which significantly affected the overall sales dynamics of the Sandero Stepway. Now regarding the power plant. The base engine of the car is a 1.6-liter engine with two different boosts - 84 and 116 forces.
Other important engine features:
- in-line arrangement of cylinders;
- number of cylinders - 4;
- number of valves - 16;
- torque - 145 Nm;
- maximum speed - 165 km / h.
In 2012, the second generation of the model, the Renault Sandero Stepway 2, was presented at the Paris Motor Show. The appearance of the car has changed dramatically, the functionality has become more diverse and attractive. The range of power plants has remained virtually unchanged. You can buy a hatchback in three trim levels. The base, as before, remained a 1.6-liter engine with the H4M index. The Renault-Nissan H4M-HR16DE engine is an evolution of the “renoshny” K4M, the two aforementioned companies took up the modernization of the latter in 2004.
Design features of the motor
The H4M engine is maximally adapted to Russian operating conditions. Even the VAZ automobile plant adopted the motor, equipping the Lada X-Ray crossover with a similar power plant. To reduce the weight and dimensions of the engine, an aluminum cylinder block was taken as the basis for the new power unit. The aluminum construction allows you to accelerate the warm-up of the engine, reduce energy losses for fuel combustion. Thus, it can be noted that the manufacturer focused on increasing the efficiency of the installation by borrowing modern technologies for the production of resource-intensive engines from leading companies.
In the past "renoshny" K4M and K7M engines, a belt was used as a timing drive, but it was decided to equip the H4M with a high-quality chain. In the H4M-HR16DE, it is reliable, on average it lasts for 120-150 thousand kilometers. The timing drive may fail ahead of time, but for this the driver himself must create unfavorable operating conditions for the car: constant high loads, overheating of the motor, use of low-quality working fluids. The first symptoms of a faulty circuit are the appearance of a characteristic crack from the engine during operation.
Potential resource of the Renault Sandero Stepway 1.6 power unit - H4M
There are no hydraulic lifters in the H4M, so every 100 thousand kilometers you will have to independently adjust the valve clearances. The system has a phase regulator, it is installed on the exhaust camshaft. In general, the mechanism is characterized by stable operation and a large resource. There were no complaints about the phase regulator from the owners of Renault Sandero Stepway. Based on the experience of operating cars with a K7M and K4M engine under the hood, we can assume the probable service life of the evolved modification of the installation - H4M-HR16DE.
The network has information that supposedly this engine "walks" 200-250 thousand kilometers. Many sources claim the resource based on the manufacturer's claims. It is worth saying that the figure of 250 thousand kilometers is a guarantee. That is, this is the minimum mileage threshold that the Renault Sandero Stepway with the H4M engine can overcome. With timely and proper maintenance, the engine will easily pass 400-450 thousand km. For this, the following must be observed:
- Only use original engine oil prescribed by the machine manufacturer. The basis of the engine is aluminum, therefore, it is necessary to constantly monitor the quality and condition of the working fluids of the system. This number includes not only lubricant, but also coolant. Elf oil is best suited for a hatchback.
- During maintenance of the H4M-HR16DE, use only air and fuel filters suitable for this version of the engine. For preventive purposes, check the CVTC valves, it is absolutely impossible to allow the "starvation" of the fluid coupling. Air filters play a significant role in the development of the entire resource of the installation. Saving on elements that, at first glance, seem not so significant, can subsequently lead to serious damage.
Reviews of car owners
The H4M-HR16DE is better than the previous "reno" installations in all respects. This engine is lighter, rid of some "chronic" diseases, consumes less fuel, while the new version of the installation is torquey and economical. As mentioned above, the car is adapted to Russian operating conditions, however, in some cases, minor problems are inevitable. For example, in regions with a frosty climate, it may be difficult to start the engine. About how to deal with a difficult start, and what is the resource of the Renault Sandero Stepway 1.6 engine, the owners' reviews will tell in detail:
- Matthew. Moscow. I have a 2012 Renault Sandero Stepway 1 with a 1.6 liter Nissan engine. Passed on this machine for 140,000 kilometers. I travel a lot, several times I went on long trips around the country. I have no complaints about the build quality or engine performance. Stable power unit, pleasing economy and resourcefulness. There were also no problems with starting. The oil does not “eat”, I fill it with Elf. The car does not "suffocate" during overtaking, it feels confident on the highway, as well as in the city. In general, I give this model a solid five.
- Yaroslav, Yalta. Acquired Sandero Stepway in 2015, second generation car. During this time, passed 45 thousand kilometers. I do not recommend owners of a new hatchback to turn the revs and load the engine at first. Refuel only with high-quality fuel, I fill AI-95 myself. It's hard for me to talk about the quality of the engine, but so far I'm happy with everything. A small drawback - there is no special dynamics. Oil from replacement to replacement, if you turn 3500-4000 rpm, then, of course, the engine will “eat” oil. I am sure that with proper maintenance, the resource of the H4M-HR16DE is more than 400 thousand kilometers.
- Igor, Stavropol. Renault Sandero Stepway, second generation, 2016, 28 thousand kilometers on the odometer. The car was taken from the salon in the maximum configuration. After the break-in, the OD flooded the original Elf, the engine, it seems to me, began to work quieter, smoother. Iridium spark plugs, haven't changed yet. Since the mileage is small, I can not say anything about the condition of the circuit. Nothing rumbles - already pleases. The automatic transmission also works properly, but sometimes the car jerks are felt at the moment of gear shifting. No more complaints. Masters say that the hatchback engine is able to overcome about 500 thousand kilometers. I think that this is a very real figure, if you do not save on maintenance.
- Mikhail, Voronezh. I still have a new Sandero Stepway, I bought it in the cabin, basic equipment, five-speed mechanics, assembly in 2017. Everyone likes the car: interesting design, high ground clearance, which is relevant for the region in which I live. I measure the oil every 5-7 days, at the service station one master said that this engine can “eat” lubricant. But in reality, everything is in order. I have passed 20 thousand km in a year, now I am flooding Elf 5W30, it feels like the engine has become quieter. There are many examples and acquaintances who have traveled more than 400 thousand kilometers in a car with the same "Nissan" engine.
- Yuri, Kaliningrad. I used to drive Renault Logan, but already in 2010 I moved to Sandero Stepway. I like the car of the first generation. Now on the odometer 210,000 km. I replaced the chain, its resource was 150 thousand kilometers. The masters said that the timing drive could serve longer, but, apparently, I put a lot of load on the engine, because I can’t drive calmly. In terms of dynamics, the H4M is noticeably more cheerful than the K4M and K7M, no matter how 116 horses under the hood. For 15,000 kilometers traveled, I add about 1 liter of oil. Now about all the problems that were during my operation of the car: once, at a load of 2000 revolutions, the phase regulator began to knock. I ended up having to change the filter. The valve was correct. No more problems. According to the resource: a reliable engine, mileage is more than 200 thousand, and it is as good as new. The figure of 400 thousand does not seem so sky-high.
- Grigory, Moscow. In 2012, he became the owner of the Renault Sandero Stepway, most recently overcame the mark of 150,000 kilometers. Most of the run in the capital. After about 90 tyk began to add a little oil. Every 8-10 thousand km I change the lubricator, I prefer Elf 5W30. The driving style is neat: I don’t pull from a place, calm and measured movement. The engine did not cause any problems. I haven’t even changed the chain yet, although it’s already necessary in time, but I don’t hear clanging and knocking during the operation of the unit. What is the result? Easily and naturally passed 150 tyk, without problems and special breakdowns. Consumption pleases, as well as the dynamics of the machine. The car will go at least the same amount. Of this I am sure.
The hatchback with a motor installed under the hood, which was jointly developed by engineers from Renault and Nissan, fell in love with many drivers for a reason. Sandero Stepway is good not only for the price and variety of trim levels, the car engine is structurally simple and studied in detail by specialists. According to the manufacturer, its resource is 250 thousand kilometers, but do not confuse the warranty indicator with the actual one.
In practice, cars with an H4M engine cover 400 thousand kilometers. In order for the installation to fully exhaust its resource, it is necessary in every possible way to create optimal conditions for the operation of the engine. There is no need to save on car maintenance and, moreover, to postpone the regulated maintenance for later. It is also important to “feed” the car with high-quality gasoline.

On the left are: flywheel; crankshaft position sensor; thermostat; thermostat housing with coolant temperature sensor.
Coils and spark plugs are located on top; oil filler neck; a receiver with absolute pressure and intake air temperature sensors, a throttle assembly with a throttle position sensor.
In the lower part of the cylinder block there are five crankshaft main bearing supports with removable covers, which are attached to the block with special bolts. The holes in the cylinder block for the bearings are machined with the covers installed, so the covers are not interchangeable and are marked on the outer surface to distinguish them (the covers are counted from the flywheel side). On the end surfaces of the middle support, sockets are made for thrust half rings that prevent axial movement of the crankshaft. The shells of the main and connecting rod bearings of the crankshaft are steel, thin-walled with an anti-friction coating applied to the working surfaces of the shells. Crankshaft with five main and four connecting rod journals. The shaft is equipped with four counterweights cast integrally with the shaft. Channels are made in the necks and cheeks of the shaft to supply oil from the main journals to the connecting rod journals. At the front end (toe) of the crankshaft are installed: an oil pump drive sprocket, a timing gear drive pulley (timing) and an auxiliary drive pulley. The toothed pulley is fixed on the shaft with a protrusion that fits into a groove on the toe of the crankshaft.
Similarly, the auxiliary drive pulley is fixed on the shaft.
The crankshaft is sealed with two oil seals, one of which (on the timing drive side) is pressed into the cylinder block cover, and the other (on the flywheel side) is pressed into the socket formed by the surfaces of the cylinder block and the main bearing cover. A flywheel is attached to the crankshaft flange with seven bolts. It is cast from cast iron and has a pressed steel crown for starting the engine with a starter. In addition, a ring gear for the crankshaft position sensor is made on the flywheel.
Connecting rods - forged steel, I-section, processed together with covers. The covers are attached to the connecting rods with special bolts and nuts. With their lower (crank) heads, the connecting rods are connected through liners to the connecting rod journals of the crankshaft, and the upper heads are connected through piston pins to the pistons.
Piston pins - steel, tubular section. The pin, pressed into the upper head of the connecting rod, rotates freely in the piston bosses. The pistons are made of aluminum alloy. The piston skirt has a complex shape: barrel-shaped in longitudinal section, and oval in transverse section. Three grooves for piston rings are machined in the upper part of the piston. The two upper piston rings are compression rings, and the lower one is oil scraper.
cylinder head:
1 - inlet valves;
2 - exhaust valves
The cylinder head is cast from aluminum alloy, common to all four cylinders. The cylinder head is centered on the block with two bushings and secured with ten screws. A non-shrink metal gasket is installed between the block and the head. On opposite sides of the cylinder head are the intake and exhaust ports. Spark plugs are installed in the center of each combustion chamber.
The valves are steel, in the cylinder head are arranged in two rows, V-shaped, two intake and two exhaust valves for each cylinder. The intake valve plate is larger than the exhaust valve. Seats and valve guides are pressed into the cylinder head. Valve guides are fitted with oil caps on top of the valve guides. The valve closes under the action of a spring. Its lower end rests on a washer, and its upper end rests on a plate, which is held by two crackers. The folded crackers have the shape of a truncated cone on the outside, and on the inside they are equipped with thrust collars that enter the groove on the valve stem. Two camshafts are installed at the top of the cylinder head. One shaft drives the intake valves of the gas distribution mechanism, and the other drives the exhaust valves.
The cams are pressed onto the camshaft
Eight cams are made on each shaft - an adjacent pair of cams simultaneously controls the valves (inlet or outlet) of each cylinder. A design feature of the camshaft is that the cams are pressed onto the tubular shaft.
Supports (beds) of camshafts (six bearings for each shaft) are detachable - located in the cylinder head and in the head cover.
Camshaft with toothed pulley and oil seal
Camshaft drive - toothed belt from the crankshaft pulley. On the shaft next to the first (counting from the camshaft pulley) support neck, a thrust flange is made, which, during assembly, enters the grooves of the block head and cover, thereby preventing axial movement of the shaft. The camshaft pulley is not fixed on the shaft with a key or pin, but only due to the friction forces that occur on the end surfaces of the pulley and shaft when the pulley fastening nut is tightened.
The toe of the camshaft is sealed with an oil seal, put on the first neck of the shaft and pressed into the socket formed by the surfaces of the cylinder head and the head cover.
valve lever
The valves are driven from the camshaft cams through the valve levers.
To increase the life of the camshaft and valve levers, the cam of the shaft acts on the lever through a roller that rotates on the axis of the lever.
Valve lever hydraulic support
The hydraulic bearings of the valve levers are installed in the sockets of the cylinder head. A hydraulic compensator with a check ball valve is installed inside the body of the hydraulic support.
The oil inside the hydraulic support comes from the line in the cylinder head through the hole in the hydraulic support body. The hydraulic support automatically ensures backlash-free contact of the camshaft cam with the valve lever roller, compensating for wear on the cam, lever, valve stem end face, seat chamfers and valve disc.
With one end, the lever rests on the spherical head of the hydraulic support (gap gap compensator), and with the other it acts on the end of the valve stem
Engine lubrication - combined. Under pressure, oil is supplied to the main and connecting rod bearings of the crankshaft, camshaft bearings and hydraulic bearings of the valve levers. Other engine components are splash lubricated.
Oil pump:
1 - driven sprocket of the drive;
2 - pump housing;
3 - pump housing cover with oil receiver
The pressure in the lubrication system is created by a gear oil pump located in the oil pan and attached to the cylinder block.
Oil pump drive(sump removed):
1 - auxiliary drive pulley;
2 – a forward cover of the block of cylinders;
3 - drive sprocket of the pump drive;
4 - drive chain;
5 - oil pump;
6 - crankshaft;
7 - cylinder block
The oil pump is driven by a chain drive from the crankshaft. The drive sprocket of the pump drive is mounted on the crankshaft under the front cover of the cylinder block. A cylindrical belt is made on the sprocket, along which the crankshaft front oil seal works. The sprocket is mounted on the crankshaft without tension and is not fixed with a key. When assembling the engine, the drive sprocket of the pump drive is clamped between the timing gear pulley and the shoulder of the crankshaft as a result of tightening the package of parts with the accessory drive pulley mounting bolt.
The torque from the crankshaft is transmitted to the sprocket only due to the frictional forces between the end surfaces of the sprocket, the toothed pulley and the crankshaft. If the accessory drive pulley bolt is loosened, the oil pump drive sprocket may begin to rotate on the crankshaft and the oil pressure in the engine will drop. The oil receiver is made in one piece with the cover of the oil pump housing. The cover is fastened with five screws to the pump body. The pressure reducing valve is located in the cover of the pump housing and is kept from falling out by a spring retainer. The oil from the pump passes through the oil filter and enters the main oil line of the cylinder block. Oil filter - full-flow, non-separable.
From the main line, oil flows to the main bearings of the crankshaft and further, through the channels in the crankshaft, to the connecting rod bearings of the shaft.
Through two vertical channels in the cylinder block, oil from the main line is supplied to the cylinder head - to the extreme (left) supports (bearings) of the camshafts. Through grooves and drillings in the extreme bearing journals of the camshafts, oil enters the shafts and then through drillings in other shaft journals to the rest of the camshaft bearings. From the cylinder head, oil flows through vertical channels into the engine sump.
The crankcase ventilation system is closed, forced, with the selection of gases through the oil separator (in the cylinder head cover), which cleans the crankcase gases from oil particles. Gases from the lower part of the crankcase enter through the internal channels in the cylinder head into the head cover and then enter the receiver and the engine intake pipe. Control, power, cooling and exhaust systems are described in the relevant chapters.
Renault Sandero is a compact budget class car, produced since 2007, available as a five-door hatchback. This car is inexpensive, and the maintenance of the vehicle also does not hit the pocket. Outwardly, the Sandero resembles the Renault Logan, but the hatchback design is more attractive.
For the first time, the French model was presented in Brazil, and a little later it was shown at the Geneva Motor Show. In Romania, Sandero is known under the Dacia brand, in 2009 the car began to be sold in Belarus and Ukraine.
At the end of 2009, the assembly of the hatchback began to be carried out at the Moscow automobile plant "Renault Russia", a car based on the Nissan B platform. There is also a version of the Renault Sandero Stepway, which differs from the standard model in increased ground clearance (by 20 mm), more impressive wheel arches and roof rails.
Many of the parts installed on the Sandero are borrowed from the Logan, so typical characteristic diseases hatchback adopted from its prototype. In 2012, an updated version of the Sandero Stepway was presented to the world, and the second-generation Sandero debuted at the Paris Motor Show.
Body and paintwork
On Renault Sandero, the body is galvanized, the body iron itself is quite strong. These cars rarely rust, mostly corrosion occurs if the car has been in an accident. The paintwork of the body is not bad, chips first of all appear on the wheel arches, in the area of the thresholds.
What are the disadvantages of engines
There are no powerful engines in the Sandero powertrain lineup, and you can’t count on sportiness here. The most popular is a four-cylinder engine with a volume of 1.4 liters and a power of 72 or 75 horsepower (8 valves).
Also, a 1.6-liter internal combustion engine is installed on the car in two versions:
16-valve - 84 liters. With.;
8-valve - 106 liters. With.
The 1.4 liter engine is somewhat weak, its thrust is not enough for a relatively heavy car. Often this motor runs to the limit, and from the load power unit resource is noticeably reduced. The 1.6-liter 8-valve internal combustion engine also does not have much power, but it is enough for city trips. With a 16-valve engine, the Sandero has enough dynamics, but the car consumes much more fuel.
timing belt on 16-cl. It is recommended to change the internal combustion engine of the K4M model every 60 thousand kilometers, it is better to replace the parts of the gas distribution mechanism with a kit (belt, water pump, tension rollers).
The range of Renault Sandero engines also includes a 1.5 DCI diesel engine, depending on the modification, its power ranges from 80 to 90 hp. With. The K9K diesel power unit is highly economical and has good traction, but in Russia, cars Sanderos with diesel engines are rare.
The petrol engines installed on the Sandero are quite reliable, but they still have some problems. One of the characteristic "diseases"- jamming of the thermostat, with such a defect, the motor may overheat or, conversely, operate in low temperature conditions. Not too long to "live" candles and high voltage wires, they often pierce the mass from dampness.
Sandero gasoline engines have a very good resource, with proper care and careful operation serve for 500 thousand km and more before overhaul.
Weaknesses in the transmission units
Only two types of transmission are installed on the hatchback:
5-speed manual transmission;
4-speed automatic transmission.
The automatic transmission is paired with a 1.6-liter 16-valve engine, the "mechanics" is put together with an 8-valve engine.
mechanical box quite noisy, but at the same time, no defects are detected in it - the gears switch smoothly, without jerks, the speeds do not fly out. Even at engine speeds of three thousand or more, vibration appears on the body, it comes precisely from the manual transmission.
The manufacturer does not provide for an oil change in the “mechanics”, the lubricant should be enough for the entire life of the gearbox. But if the transmission already passed 100 thousand km, it is better to replace the oil in the unit, it will not be worse from this.
Four-speed "automatic machines" are not famous for their special reliability, automatic transmissions are mainly fail due to overheating. An automatic transmission often requires repair on a run of about one hundred thousand kilometers, an oil change in an automatic transmission should be done after 50 thousand km.
Chassis and sores in the suspension
The rear suspension on the Sandero is a beam type, the front is a standard MacPherson strut. The design of the chassis of the car is quite simple, so the suspension elements fail in general infrequently. Spare parts for the car are relatively inexpensive, repairing the chassis is not very difficult.
First on Renault Sandero “surrender” bushings and stabilizer struts, they serve an average of 50-60 thousand km. The rear and front shock absorbers are sensitive to the quality of the road surface, they begin to leak quickly if the car is often used on a bad road. But in any case, the resource of these parts is at least forty thousand kilometers, the original shock absorbers last longer (70-80 thousand km each).
steering rack not too "survivable", the plastic sleeve wears out first. The manufacturer did not provide repair kits for the rack, but parts can be supplied from another car model, for example, from BMW. Before repairing the steering gear, you should check the backlash in the tips and rods, the resource of which is 60-70 thousand km.
Life time front brake pads are standard - an average of about 30-40 thousand km. If you lubricate the guides of the front calipers, the pads can last longer, and the life of the parts largely depends on the driving style.
Vehicle interior
The interior of the Renault Sandero is nothing special - the interior looks gray and somewhat dull. But there is enough space inside the car, but the trunk of the car is small (320 liters), although if you expand the rear seats, it becomes quite roomy (1200 liters). The plastic interior is not very high quality, but the Sandero still belongs to the budget class, and therefore you should not expect the best from the interior trim.
Based on the universal platform B0. In the arsenal of the model there are three 1.6-liter engines: an 8-valve K7M with a return of 82 hp, a 16-valve K4M with a capacity of 102 hp. and 16-valve H4M 113 hp Available gearboxes are also three: 5-speed "mechanics", 5-speed "robot" and 4-band "automatic" DP2. Mechanical and robotic boxes rely on the “younger” 82-horsepower engine, the same manual gearbox and 4-speed automatic transmission are installed along with a 102-horsepower unit. The new 113-horsepower engine is offered only with "mechanics". In general, in terms of technical characteristics, the Renault Sandero Stepway is very close to the base Sandero hatchback and sedan, as well as some other Renault and Nissan platform models. You can distinguish the off-road version of Sandero from the usual one by the following features:
- 195 mm ground clearance (+40 mm);
- body length and height increased to 4080 and 1618 mm, respectively;
- 16-inch wheels with 205/55 R16 tires (Sandero has 15-inch wheels and 185/65 R15 tires);
- stiffer suspension settings and a different anti-roll bar;
- protective plastic lining around the perimeter of the body.
The fuel consumption of Renault Sandero Stepway 2 is approximately the same for all modifications - 6.9-7.3 liters per 100 km. Only the version with an “automatic” is knocked out of the general range, consuming an average of about 8.5 liters.
The volume of the hatchback trunk with the vertical position of the backs of all seats is 320 liters. Folded second-row seats increase the capacity of the cargo compartment to 1200 liters.
The full technical specifications of the Renault Sandero Stepway are summarized in the table:

The K7J and K7M engines are identical in design and differ only in displacement. The K7J engine has a displacement of 1.4 liters, while the K7M engine has a displacement of 1.6 liters. The increase in working volume is obtained due to the larger crank radius of the crankshaft and, consequently, the larger piston stroke.
Both engines are gasoline, four-stroke, four-cylinder, in-line, eight-valve, with an overhead camshaft.
Warning: The order of operation of the cylinders: 1-3-4-2, counting - from the flywheel.

The engine cylinder block is cast iron, the cylinders are bored directly in the block.
In the lower part of the cylinder block there are five crankshaft main bearing supports with removable covers, which are attached to the block with special bolts. The holes in the cylinder block for the bearings are machined with the covers installed, so the covers are not interchangeable and are marked on the outer surface to distinguish them (the covers are counted from the flywheel side). On the end surfaces of the middle support, sockets are made for thrust half rings that prevent axial movement of the crankshaft.
The shells of the main and connecting rod bearings of the crankshaft are steel, thin-walled with an anti-friction coating applied to the working surfaces. Crankshaft with five main and four connecting rod journals. The shaft is equipped with four counterweights cast integrally with it. The counterweights are made on the continuation of the "cheeks" of the engine crankshaft. Counterweights are designed to balance the forces and moments of inertia arising from the movement of the crank mechanism during engine operation. To supply oil from the main journals to the connecting rods, channels are made in the necks and cheeks of the shaft.
At the front end (toe) of the crankshaft are installed: an oil pump drive sprocket, a timing gear drive pulley (timing) and an auxiliary drive pulley. The toothed pulley is fixed on the shaft with a protrusion that fits into the groove on the crankshaft toe and prevents the pulley from turning. Similarly, the auxiliary drive pulley is fixed on the shaft.
1 - crown for the crankshaft position sensor;
2 - crown for starting the engine
A flywheel is attached to the crankshaft flange with seven bolts. It is cast from cast iron and has a pressed steel crown for starting the engine with a starter. In addition, a ring gear for the crankshaft position sensor is made on the flywheel.

Connecting rods - steel, I-section, processed together with covers. The covers are attached to the connecting rods with special bolts and nuts.
Piston pin - steel, tubular section. The pin, pressed into the upper head of the connecting rod, rotates freely in the piston bosses.
The piston is made of aluminum alloy. The piston skirt has a complex shape: in the longitudinal section it is barrel-shaped, in the transverse section it is oval. Three grooves for piston rings are machined in the upper part of the piston. The two upper piston rings are compression rings, and the lower one is oil scraper. Compression rings prevent the breakthrough of gases from the cylinder into the crankcase and contribute to the removal of heat from the piston to the cylinder.
The oil scraper ring removes excess oil from the cylinder walls as the piston moves.

10 - valve rocker;
11 – a bolt of fastening of an axis of yokes of valves;
12 - the axis of the rocker arms of the valves;
13 - thrust flange of the camshaft
The cylinder head is made of aluminum alloy, common to all four cylinders. It is centered on the block with two bushings and fastened with ten screws. A non-shrink metal gasket is installed between the block and the head. At the top of the cylinder head are five bearings (bearings) of the camshaft. The supports are made one-piece, and the camshaft is inserted into them from the timing drive side. The camshaft is driven by a toothed belt from the crankshaft.
In the extreme bearing neck of the camshaft (from the flywheel side), a groove is made, which includes a thrust flange that prevents axial movement of the shaft. The thrust flange is attached to the cylinder head of the camshaft with five bolts attached to the axis of the rocker arms. The rocker arms are kept from displacement along the axis by two brackets, which are fastened with bolts for attaching the rocker arm axis. Screws are screwed into the rocker arms, which serve to adjust the thermal gaps in the valve drive. The adjusting screws are secured against loosening by locknuts. Seats and valve guides are pressed into the cylinder head.
Valve guides are fitted with oil caps on top of the valve guides. Valves are steel, arranged in two rows, obliquely to the plane passing through the axis of the cylinders. In front (along the direction of the car) there is a row of exhaust valves, and at the back - a row of intake valves. The intake valve plate is larger than the exhaust valve.
The valve is opened by a rocker arm, one end of which rests on the camshaft cam, and the other, through an adjusting screw, on the end of the valve stem. The valve closes under the action of a spring. Its lower end rests on a washer, and its upper end rests on a plate, which is held by two crackers. The folded crackers have the shape of a truncated cone on the outside, and on the inside they are equipped with thrust collars that enter the groove on the valve stem.
Oil pump drive (sump removed):
1 - auxiliary drive pulley;
2 – a forward cover of the block of cylinders;
3 - drive sprocket of the pump drive;
4 - drive chain;
5 - oil pump;
6 - crankshaft;
7 - cylinder block
Engine lubrication - combined. Under pressure, the crankshaft main and connecting rod bearings and camshaft bearings are lubricated. Other engine components are splash lubricated. The pressure in the lubrication system is created by a gear oil pump located in the front in the oil pan and attached to the cylinder block. The oil pump is driven by a chain drive from the crankshaft.
Oil pump:
1 - driven sprocket of the drive;
2 - pump housing;
3 - pump housing cover with oil receiver
The drive sprocket of the pump drive is mounted on the crankshaft under the front cover of the cylinder block. A cylindrical belt is made on the sprocket, along which the crankshaft front oil seal works. The sprocket is mounted on the crankshaft without tension and is not fixed with a key. When assembling the engine, the drive sprocket of the pump drive is clamped between the timing gear pulley and the shoulder of the crankshaft as a result of tightening the package of parts with the accessory drive pulley mounting bolt. The torque from the crankshaft is transmitted to the sprocket only due to the frictional forces between the end surfaces of the sprocket, the toothed pulley and the crankshaft.
Warning: If the accessory drive pulley bolt is loosened, the oil pump drive sprocket may begin to rotate on the crankshaft and the oil pressure in the engine will drop.
The oil receiver is made in one piece with the cover of the oil pump housing. The cover is fastened with five screws to the pump body.
The pressure reducing valve is located in the cover of the pump housing and is kept from falling out by a spring retainer.
The oil from the pump passes through the oil filter and enters the oil line made in the cylinder block. Oil filter - full-flow, non-separable. From the line, oil flows to the main bearings of the crankshaft and further, through the channels in the crankshaft, to the connecting rod bearings. Through a vertical channel in the cylinder block, oil from the line is supplied to the cylinder head - to the middle bearing of the camshaft. An annular groove is made in the middle support neck of the camshaft, through which the oil passes to the hollow bolt of the rocker arm axle. Further, the oil, through a hollow bolt, enters the channel made in the axis of the rocker arms, and from there - to the rocker arms and through other hollow axle bolts - to the rest of the camshaft bearings.
Holes are made in the rocker arms through which oil is sprayed onto the camshaft cams.
From the cylinder head, oil flows through vertical channels into the engine sump.
The crankcase ventilation system is closed, forced, with the selection of gases through the oil separator (in the cylinder head cover), which cleans the crankcase gases from oil particles. Gases from the lower part of the crankcase enter through the internal channels in the cylinder head into the head cover and then, through two hoses (the main circuit and the idle circuit), enter the engine intake pipe. Through the main circuit hose, crankcase gases are discharged at partial and full load modes into the space in front of the throttle valve.
Through the idle circuit hose, crankcase gases are discharged into the space behind the throttle valve both in partial and full load modes, and in idling mode.
Control, power, cooling and exhaust systems are described in the relevant chapters.
