Abstract: The invention relates to a method for operating an internal combustion engine, and air/gas mixture being introduced into the working chamber thereof and ignited by means of an ignition system. The above is carried out whereby the air/gas mixture is at least temporarily enriched. A channel (14a, 14b) is let into the cylinder head (1) from a cylinder head external wall into the working chamber (5) or a pre-combustion chamber and a gas or a gas/air mixture may be introduced in a controlled manner into the working chamber (5) or the pre-combustion chamber, by means of said channel (14a, 14b). According to the invention, the above embodiment or method permits the cycle variations in the combustion pressure to be avoided.

Abstract: The governor for a gasoline engine is a roller-shaped rotary slide valve (8a, 8b)which permits precise adjustment of the quantity of gas-air mixture supplied to the combustion chamber. The actuation forces for operating the rotary slide valve (8a, 8b) are lower than previously used throttle valves, which permits use of a smaller and less expensive control device for operating the valve.
