Note: The procedures for removing and installing the oil filter, changing the oil and filling containers are given in the chapter "Maintenance and general inspection and adjustment procedures".
Description of the lubrication system
Lubrication system with full-flow oil cleaning and pressurized oil supply to the main moving parts and assemblies of the engine. The lubrication system includes: an oil pan, an oil pump, an oil filter and various elements that provide oil to various moving parts of the engine.
The oil from the sump is pumped by the oil pump through the oil receiver into the oil filter. After passing through the oil filter, part of the oil is fed through various channels in the cylinder block and through the holes to the crankshaft main bearings. Drillings in the crankshaft supply oil 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 spraying from the oil holes of the connecting rods.
Part of the oil after passing through the oil filter through the drillings in the cylinder block is sent to the cylinder head to the hydraulic lifters (GDI engines) and for lubricating the rocker shaft, each rocker arm, camshaft and valve stems.
After performing its functions, the oil under the action of gravity (by gravity) returns to the tray. A dipstick is installed to control the oil level in the sump. In addition, an emergency engine oil pressure sensor is installed to control the oil pressure.
The oil filter is a full-flow type with a paper filter element, mounted on a bracket, near the oil pump housing. Inside the filter, a bypass valve is installed in front of the filter element, which opens with an increase in pressure in front of the filter in case the filter element is clogged with contaminants.
The engine is equipped with a trochoid type oil pump. Inside it are the driving and driven rotors with internal gearing, which rotate in the same direction.
