Two-stroke internal combustion engine

摘要

The scavenging of a two-stroke internal combustion engine is decisively improved and simplified in that the control device for the scavenging is a spin controlling the transfer port or the exhaust ports. This spin may be arranged on the cylinder head or also on the piston, the transfer port being arranged in the head of the piston in the former case and the exhaust port(s) being assigned to the cylinder head in the second case. <IMAGE>
