Abstract
An internal combustion engine has a combustion chamber, from which exhaust gas can be discharged by way of at least one exhaust valve. An engine braking device includes an hydraulic additional valve control unit is integrated into a connecting mechanism connecting the exhaust valve to a camshaft and holding the exhaust valve in a partially opened position when the engine brake is actuated. The connecting mechanism includes a rocker lever and an intermediate element between the rocker lever and the exhaust valve. The hydraulic additional valve control unit of the engine braking device has a first piston-cylinder unit for the temporary partial opening of one exhaust valve, and an hydraulic valve lash compensating mechanism has a second piston-cylinder unit for counteracting valve lash. The first piston-cylinder unit is arranged in or on the intermediate element. The second piston-cylinder unit is arranged in or on the rocker lever.
