Zusammenfassung:	PURPOSE:To improve volumetric efficiency of a cylinder for supercharge through utilization of a phenomenon of direct blow from an intake port to an exhaust port by forming the bottom of a cylinder head in a recession. CONSTITUTION:An intake port 13 and an exhaust port 14 are respectively positioned, in a plane view of an engine 1, on both the left and the right sides with respect to the longitudinal center line of the engine. On the other hand, in a part where the intake port 13 and the exhaust port 14 open into a cylinder chamber, a partition wall part 36 partitioning said ports 13 and 14 forms a recession as much as a dimension H from the bottom 19 of a cylinder head, to the side reverse to the cylinder chamber. This reduces turnabout of air when it flows out of the exhaust port 14 after flowing into the cylinder chamber from the intake prot 13, and the air flows through said port 14 as shown by an arrow A.
