Abstract
A combustion chamber configuration and porting arrangement for a two-cycle crankcase compression diesel engine that improves scavenging. An exhaust port opens into one side of the engine cylinder bore and the scavenge ports and a precombustion chamber are configured so that they discharge their gases in an area diametrically opposed to the exhaust port for improving scavenging.
