The engine lubrication system is designed to:
- for lubrication of engine units and assemblies. Creation of an oil film between rubbing surfaces (pistons and cylinders, main bearings, valve drive and other parts) ensures their minimal wear;
- eliminating gaps between the piston, piston rings and cylinder bore;
- cooling of parts such as pistons, crankshaft bearings.
The lubrication system uses a rotary oil pump driven by the crankshaft. The pump is mounted directly to the front of the crankcase.

Oil nozzles (Fig. 86), located on the inside of the crankcase, are designed to cool the pistons.
