OILPAN
This engine lubrication system consists of oil filter 1 (strainer), oil pump, relief valve, oil filter
cartridge and oil switch. The oil pump suctions lubrication oil from the oil pan through oil filter
1,
and the oil flows down to the filter cartridge, where it is further filtered. Then the oil is forced to
crankshaft, connecting rods, idle gear, camshaft and rocker arm shaft to lubricate each part.
Some
part of oil, splashed by the crankshaft or leaking and dropping from gaps of each part, lubricates
these parts: pistons, cylinders, small ends of connecting rods, tappets, pushrods, inlet and exhaust
valves and timing gears.
