Abstract
A combustion chamber and scavenging configuration for a two-cycle internal combustion engine. The combustion chamber is comprised of an offset recess surrounded by a squish area. An exhaust port is formed on the side of the cylinder opposite to the area where the recess is offset while the intake or transfer ports are disposed on the side to which the recess is offset. The transfer or scavenge ports are configured so as to open progressively first diametrically opposite to the exhaust port and then in an area extending around the area toward the exhaust port.
