Abstract

A port for a cylinder of a two-stroke cycle engine includes at least one generally circumferential array of port openings. Port openings have a shape that reduces ring clipping during engine operation. The port opening shape is defined at a bore surface by opposing top and bottom edges joined by side edges. Each of the top and bottom edges is characterized by rounded corner transitions to the side edges, a rounded peak, and inclined ramp portions extending from the rounded corner transitions to the rounded peak.
