Water-cooled two-stroke internal combustion engine

摘要

A two cylinder engine has a reverse scavenging system with exhaust ports positioned on either front end of the cylinder block and directed towards areas without any ports which are located next to each other in the center of the engine. Intake ports are directed towards either side wall of each cylinder where they open into charge compartments which are closed, e.g., with covers whose dimensions will permit milling and core-pulling tools to have access to the intake ports. Between the port-free areas of the cylinders a gap is provided which connects the water jackets of the cylinders in the upper part and the charge compartments in the lower part thereof.
