INTERNAL COMBUSTION ENGINE COLD RUNNING-IN METHOD Russian patent published in 1998 - IPC

Abstract RU 2105892 C1

FIELD: mechanical engineering; running-in of internal combustion engine after manufacture or repair. SUBSTANCE: in process of running-in lubricating conditions corresponding to most intensive running-in are maintained by decreasing oil pressure in main oil gallery from maximum to minimum tolerable values for operation at no load, depending on degree of alignment of engine friction surfaces which is evaluated by crankshaft rotational speed. Oil pump drive operates independently from internal combustion engine. EFFECT: improved quality of running-in. 2 dwg
