ABSTRACT:
The invention relates to a method for operating an internal combustion engine of a motor vehicle in engine braking mode, in which the internal combustion engine is operated with at least one unfired cylinder, and the internal combustion engine has variably controllable valve drives for intake and exhaust valves of each cylinder, and a turbocharger device for increasing pressure in the intake tract of the cylinder. The object of the invention is to improve the engine braking characteristic and the response of the turbocharger device. The object is achieved by controlling the intake valves and exhaust valves for setting a specified braking torque that may be set by compressing the air mass in each unfired cylinder.
