Abstract
An internal combustion engine including at least one exhaust valve for withdrawal of exhaust gas from at least one combustion chamber, and an engine brake device having a hydraulic valve auxiliary control unit by means of which the exhaust valve can be held in a temporarily open position when the engine brake device is actuated. The engine also includes a hydraulic valve play compensation mechanism for the exhaust valve, and an oil channel that for supplying oil to the valve auxiliary control unit is formed between the latter and the valve play compensation mechanism. For compensation of valve play of the exhaust valve, the oil channel can be closed off via a closure unit.
