Abstract

This lubrication system includes a pump feeding a main line which provides oil to a support interface for a crank shaft of oil engine and an auxiliary line connected to at least one piston cooling jet. The pump is a variable flow pump controlled on the basis of oil pressure in the main line. A proportional means is mounted on the auxiliary line. This means is adapted to control oil flow in the auxiliary line depending on the working conditions of the engine, e.g. oil temperature, torque to be delivered or rotational speed of the engine.
