Abstract
An internal-combustion engine has an engine braking device which has brake valves by way of which the combustion chamber content of the cylinders can be diverted in the engine braking phase. In the engine braking operation, the brake valves are changed into the opening position. In order to increase the operational reliability of the engine braking device, a blocking device is provided which acts upon the brake valves and which can be adjusted between a holding position and a release position. In the holding position of the blocking device, the brake valves are held in the opening position.
