摘要： A throttle valve is positioned at the entrance to a swirl type of suction passage near to the corresponding intake valve of a cylinder in an internal combustion engine. The valve is designed so that when it is opened only slightly (e.g. 30.degree.-40.degree.), the flow of intake gas passing therethrough converges to flow eccentrically along one side of the suction passage. This arrangement provides full control of the intake gas in the suction passage before it reaches the combustion chamber, even when the volume of flow is small, thereby producing an effective swirl within the combustion chamber for all operating conditions of the engine.

摘要： A helically-shaped intake port comprising a helical portion and an inlet passage portion which is tangentially connected to the helical portion and extends so as to be slightly curved. The intake valve is arranged at the outlet open end of the helical portion. The first side wall of the inlet passage portion, which is located near the axis of the intake valve, has on its upper portion an inclined wall portion which is arranged to be directed downwards. The inlet passage portion has an open inlet end formed on the flat side wall of the cylinder head. The inlet passage portion is so arranged that the longitudinal axis thereof obliquely intersects with a straight line passing through the center of the valve head of the intake valve and extending parpendicular to the outer side wall of the cylinder head. The inlet end of the inlet passage portion is arranged at a position remote from the straight line so that the inlet end does not include the straight line.

摘要： A cam lobe is formed as a single part, not formed together with a shaft body. The shaft body penetrates through bearing holes, as well as a mounting hole provided in the cam lobe, which is arranged in between adjacent bearing holes. The bearing holes each in a perfect circular shape can be achieved, since there is no need to divide the bearing holes into two semi-circular arc shaped concave portions. Consequently, a camshaft can be supported so as to rotate smoothly.
