The lubrication system consists of an oil pan, an oil pump, an oil filter and various channels.
The oil pump is driven by the crankshaft. The bypass valve in the oil pump maintains the pressure in the engine lubrication system at a certain level. When it is exceeded, the bypass valve opens and some of the oil flows back into the oil pan.
The filter has a bypass valve through which, in the event of severe contamination of the filter, unfiltered oil flows directly into the oil line. The oil, cleaned by the oil filter, enters the main oil line.
The oil flow then splits into two streams. One stream of oil is supplied to the main bearings of the crankshaft, and through drilled channels it also lubricates the connecting rod bearings. To cool the pistons, oil is sprayed through nozzles onto the lower part of the pistons.
The second flow of oil is supplied through the channels to the cylinder head to lubricate the camshaft bearings and to the hydraulic tappets.
After passing through the cylinder head and block, the oil drains into the oil pan.
