Abstract
The invention is an improved piston and cylinder arrangement for a loop charged two-stroke engine wherein all input passages are open channels in the cylinder wall and the top annular edge of the piston is rounded. The rounded edge on the piston cooperates with the described scavenging and input passages to reduce drag and, cause the incoming charge to flow more horizontally over the piston head; thereby improving scavenging and volumetric efficiency.
