Abstract

The invention relates to a method for operating an internal combustion engine, in which the internal combustion engine has at least one first combustion chamber, in which combustion processes take place during fired operation of the first combustion chamber, at least one second combustion chamber, in which combustion processes take place during a fired operation of the second combustion chamber, a first knock sensor assigned to the first combustion chamber, by means of which irregular combustions in the first combustion chamber can be detected, and a second knock sensor assigned to the second combustion chamber, by means of which irregular combustions in the second combustion chamber can be detected. The internal combustion engine is operated in a first operating state in which channel switching is carried out. A switch is made from the first operating state to a second operating state in which channel switching does not take place.
