ABSTRACT:
An improved combustion system particularly for a larger type diesel engine featuring a prechamber with a generally cup-shaped bottom tip portion facing the engine's main combustion chamber and with a central transfer passage substantially aligned with the centerline of the prechamber and a plurality of additional transfer passages circumferentially arranged about the centerline of the prechamber. The improved complete combustion system uses a piston with a deep bowl formed in the piston crown into which the central transfer passage directs a strong direct charge of products of combustion from the prechamber.
