Abstract
A method for controlling a multi-cylinder combustion engine, wherein the combustion engine has a first operating state in which all cylinders are active, and a second operating state in which one of the multiple cylinders is active and one of the multiple cylinders is deactivated. The method comprises switching the combustion engine from the first to the second operating state, wherein, in the cylinder to be deactivated, an exhaust valve is deactivated after a combustion stroke and an intake valve is deactivated before an intake stroke following the combustion stroke in the closed state, and changing an ignition angle of the cylinder to be deactivated to an earlier ignition time and an optional change of the air/fuel mixture leads to a reduction in a temperature of an exhaust gas arising during the combustion stroke.
