Abstract

The invention is directed to an internal combustion engine, especially for a motor vehicle. The engine has a combustion chamber into which fuel can be injected in at least two operating modes. A control apparatus is provided with which a switchover between the operating modes can be effected. A desired value (rlmd$s) can be determined with the control apparatus for the air charge in the combustion chamber. The desired value (rlmd$s) defines a maximum value for the air charge in the combustion chamber which is not exceeded.
