A fuel can be introduced directly into the combustion chamber, and at least one gas exchange inlet valve and one gas exchange outlet valve are provided for a gas exchange. An intermediate compression can be set in the combustion chamber at a gas exchange top dead center and a main compression can be set at an ignition top dead center.
