Claims

[Scope of utility model registration request]

A combustion chamber is provided on the inner surface of the cylinder head, facing the upper surface of the piston that slides into the cylinder, and two intake valves are arranged in parallel on one side of the roof surface of the combustion chamber, and one exhaust valve is arranged on the other side. placed on the combustion chamber, 1
Two valve drive camshafts are rotatably supported, and the valve drive cam on the valve drive camshaft and the upper ends of the two intake valves and one exhaust valve are pivotably supported on a rocker arm shaft. In a valve train for a cross-flow type three-valve internal combustion engine, which is connected by a rocker arm for intake and exhaust, the valve drive camshaft is disposed substantially on the axis of the cylinder, and the valve drive camshaft is arranged approximately on the axis of the cylinder, and Two rocker arms for intake are arranged in parallel on the combustion chamber adjacent to each other, and one rocker arm for exhaust is arranged adjacent to the rocker arm for intake near the center of the cylinder on the combustion chamber. 1. A valve operating system for a three-valve internal combustion engine, characterized in that the three rocker arms for intake and exhaust are arranged to be biased toward the other side and are formed in the same manner so that they are interchangeable.
