Engine greasing

The oil pump – the pump of trokhoidny type established under the crankshaft. Oil is soaked up through a grid of the oil pump and arrives via the pump to the oil filter. The filtered oil arrives on two channels in the block of cylinders. On one channel, oil reaches basic bearings of the crankshaft. Oil from basic bearings of the crankshaft supplies rod bearings with the help взаимопересекающихся the channels drilled in the crankshaft, and then is injected from a big head of a rod for greasing of the piston, piston rings and a cylinder wall.

On other channel, oil rises to a head of the cylinder and greases valves and cam-shafts etc., passing through an internal lubricant flute of cam-shafts.

On the oil pump there is a reduktsionny valve of system of greasing. This valve starts to reduce pressure of oil if pressure exceeds 420 kPas (4.2 kg/cm2, 59.7 пси).
