Engine greasing

The oil pump is established on the crankshaft from a pulley of a cranked shaft. 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 cylinder block. On one channel, oil reaches the basic bearing of a cranked shaft. Oil from the basic bearing of a cranked shaft supplies the bearing of the top head of a rod with the help взаимопересекающихся the channels drilled in the crankshaft, and then is injected into the small opening provided on the bigger end of a connecting 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 a cam-shaft neck, a valve yoke, a cam-shaft etc., passing through the oil highway in a yoke axis.

To us the oil pump there is a reduktsionny valve of system of greasing. This valve starts to reduce pressure of oil if pressure exceeds 400 kPas (4.0 kg/cm2, 56.9 пси). The dumped oil arrives back in an oil pan.
