Abstract (en)
[origin: WO2005088105A1] The invention relates to a method for operating an internal combustion engine of a motor vehicle during engine braking. According to the invention, the internal combustion engine is operated with at least one unfired cylinder, and the internal combustion engine has variably controllable valve gears for intake valves and exhaust valves of each cylinder and has a supercharger device for increasing the pressure inside the intake tract of the cylinder. The aim of the invention is to improve the engine braking behavior and the response of the supercharger device of a motor vehicle. To this end, the invention provides that the intake valves and exhaust valves are controlled for setting a specified braking torque that can be set by compressing the air mass inside each unfired cylinder.
