Abstract

An internal combustion engine includes an exhaust valve for removing exhaust gas from a combustion chamber and an engine braking device with a hydraulic valve control unit by which the exhaust valve can be held in an intermediate open position when the engine braking device is actuated. A hydraulic valve lash compensation mechanism for the exhaust valve and a control channel formed between the hydraulic valve control unit and the valve lash compensation mechanism for feeding oil to the hydraulic valve control unit that can be closed by a closure element to compensate for the valve lash of the exhaust valve. A counter-holder is constructed as a piston-cylinder unit. The counter-holder forms a variable stop for a valve bridge cooperating with the valve lash compensation mechanism.
