Note: The procedures for removing and installing the oil filter, changing the oil and filling capacities are given in the chapter "Maintenance and general check and adjustment procedures".
Description of the lubrication system
Lubrication system with full-flow oil cleaning and oil supply under pressure to the main moving parts and units of the engine. The lubrication system includes: an oil pan, an oil pump, an oil filter and various elements that provide oil supply to various moving parts of the engine.
Oil from the sump is pumped by the oil pump through the oil receiver into the oil filter. After passing the oil filter, some of the oil is fed through various channels in the cylinder block and through holes to the main bearings of the crankshaft. Through the holes in the crankshaft, the oil is fed to the connecting rod bearings of the crankshaft. Lubrication of the cylinder walls and the lower part of the piston bottom is carried out mainly by splashing from the oil holes of the connecting rods.
Some of the oil, after passing through the oil filter through the holes in the cylinder block, is directed to the cylinder head to the hydraulic compensators (GDI engines) and to lubricate the rocker arm shaft, each rocker arm, the camshaft and the valve stems.
After performing its functions, the oil returns to the sump under the force of gravity (by gravity). A dipstick is installed in the sump to monitor the oil level. In addition, an emergency engine oil pressure sensor is installed to monitor the oil pressure.
Oil filter - full-flow type with a paper filter element, mounted on a bracket, near the oil pump housing. Inside the filter, in front of the filter element, a bypass valve is installed, which opens when the pressure increases in front of the filter in case of clogging of the filter element with polluting particles.
The engine is equipped with a trochoid oil pump. Inside it are the leading and driven rotors with internal engagement, which rotate in the same direction.
