機関。In an internal combustion engine in which the cross-sectional shape of the cylinder hole formed in the cylinder block is formed into an elliptical shape or an elliptical shape with a large ratio of the major axis to the minor axis, there is a protrusion on the upper surface of the piston in the direction of the central minor axis. What is claimed is: 1. An internal combustion engine characterized by providing a smooth guide surface extending from the protruding strip to the outer periphery of an upper surface corresponding to each port provided on the cylinder block.
