。[Scope of Claim for Utility Model Registration] A plurality of cylinders are arranged in a staggered manner left and right along the axial direction of the crankshaft, and two cylinders are arranged along the axial direction of the crankshaft in a single cylinder head provided above the combustion chamber of each cylinder. A book camshaft is installed side by side,
In a double overhead camshaft engine with a crossed valve arrangement structure, in which each camshaft drives the valves of the cylinder located directly below it and the valves of the cylinder located on the opposite side, reciprocating motion occurs within each cylinder. The top surface of each piston is formed approximately perpendicular to the straight line that bisects the angle formed by the two valves driven by different camshafts corresponding to that cylinder, and all intake ports are located above the combustion chamber. A double overhead camshaft engine characterized in that the exhaust ports are directed from the wall to one side of the cylinder head, and all exhaust ports are directed from the upper wall of the combustion chamber to the other side of the cylinder head.
