Lubrication method for internal combustion engine and device for implementing it

摘要

Lubrication method for internal combustion engine, particularly equipping motor vehicles, using pressurised circulation of lubrication liquid (lubricant) such as oil, supplying the engine through the various lubrication galleries (ramps) (7, 9) and particularly the main gallery (7) serving the crankshaft bearings, characterised in that the pressure of the lubrication liquid is adjusted so as to generate minimum hydrodynamic friction during operation of the said engine. <IMAGE>
