METHOD OF COLD RUNNING-IN OF INTERNAL COMBUSTION ENGINE Russian patent published in 1996 - IPC

FIELD: mechanical engineering; engines; running-in if engine parts after manufacture and repair. SUBSTANCE: during cold running-in of engine repeated ring circulation of air mixture with special additive is provided by connecting exhaust manifold with carburetor venturi. Invention provides cutting down consumption of additive and running-in time, enhanced quality of running-in of cylinder-piston group parts which contributes to realization of selective transfer of metal from additive to friction surfaces of parts. EFFECT: enhanced quality of running-in. 1 dwg
