ABSTRACT:
Internal combustion engine constituted such that two inlets are provided to a sub-suction path which is provided separately from the main suction path and serves to inject gas such as air or air-fuel mixture at high velocity in the peripheral direction of a combustion chamber at the suction stroke; one of said inlets is located upstream of the throttle valve, the other located in the air path of the carburetor at a position where the throttle valve can be shut in time of idling, wherein the effective opening area of the throttle valve can be enlarged through appropriate number and form of the inlets to be shut by the throttle valve and the downstream side inlet of the two inlets is set to be within the range of an angle, i.e., the downstream side inlet is located within the range of 60.degree.-120.degree. in terms of the angle which is made by the rotational axis of the throttle valve and an imaginary line which links the downstream side inlet and the center of the main suction path where the throttle valve is located.
