Abstract

In an engine braking method for a supercharged internal combustion engine, wherein combustion air, which is under boost pressure and is supplied to the cylinders under the control of engine inlet and outlet valves, is compressed in the cylinders and is subsequently discharged into the exhaust tract, engine braking takes place in a two-stroke operating mode.
