Abstract

A loop scavenge two-cycle internal combustion engine that includes a partial wall partition disposed between a scavenging path and a cylinder bore, with a cooling port formed in the partial wall partition for enabling fresh gas in the scavenging path to contact directly with a peripheral wall of a piston in the cylinder. The fresh gas in the scavenging path directly contacts and efficiently cools the peripheral surface of the piston to prevent heat rise and distortion within the engine. The partial wall partition and cooling port maximize both cooling efficiently and cylinder strength and durability.
