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.
