Abstract
A method and a device for operating an internal combustion engine are provided which make it possible to implement different deceleration requests to the internal combustion engine by switching over between half engine operation and full engine operation. A deceleration request is received particularly in a nonoperating state. A switchover is made between a first operating state and a second operating state of the internal combustion engine as a function of the magnitude of the deceleration request. The first operating state and the second operating state differ, in this instance, in the number of cylinders whose charge changing process is interrupted.
