An internal combustion engine comprising - an exhaust valve (3, 4) for discharging exhaust gas from a combustion chamber, - a valve bridge (5; 5a) on which to mount the exhaust valve (3, 4), - a tilting lever for displacing the valve bridge (5; 5a), - an engine-braking device with a hydraulic valve-control unit, -- which is arranged between the exhaust valve and the valve bridge (5; 5a), -- which, for oil-provision purposes, is connected to an oil-providing channel, and -- by means of which the exhaust valve, with the engine-braking device actuated, can be retained in a partially open position, - an abutment for providing a stop for the valve bridge (5; 5a), - a control channel, which, for providing the hydraulic valve-control unit with oil, is connected to the oil-providing channel, characterized in that - a hydraulic valve-clearance-compensation mechanism (11; 11a) is provided for the exhaust valve (3, 4), -- said mechanism being arranged between the tilting lever and the valve bridge (5; 5a), and -- being connected, for oil-provision purposes, to the oil-providing channel, - the control channel, for compensating for the valve clearance of the exhaust valve (3, 4), can be closed by means of a closure element, and - the abutment, for adaptation of the stop to the position of the valve-clearance-compensation mechanism (11; 11a), is designed in the form of a hydraulic piston/cylinder unit. - an exhaust valve (3, 4) for discharging exhaust gas from a combustion chamber, - a valve bridge (5; 5a) on which to mount the exhaust valve (3, 4), - a tilting lever for displacing the valve bridge (5; 5a), - an engine-braking device with a hydraulic valve-control unit, -- which is arranged between the exhaust valve and the valve bridge (5; 5a), -- which, for oil-provision purposes, is connected to an oil-providing channel, and -- by means of which the exhaust valve, with the engine-braking device actuated, can be retained in a partially open position, -- which is arranged between the exhaust valve and the valve bridge (5; 5a), -- which, for oil-provision purposes, is connected to an oil-providing channel, and -- by means of which the exhaust valve, with the engine-braking device actuated, can be retained in a partially open position, - an abutment for providing a stop for the valve bridge (5; 5a), - a control channel, which, for providing the hydraulic valve-control unit with oil, is connected to the oil-providing channel, - a hydraulic valve-clearance-compensation mechanism (11; 11a) is provided for the exhaust valve (3, 4), -- said mechanism being arranged between the tilting lever and the valve bridge (5; 5a), and -- being connected, for oil-provision purposes, to the oil-providing channel, -- said mechanism being arranged between the tilting lever and the valve bridge (5; 5a), and -- being connected, for oil-provision purposes, to the oil-providing channel, - the control channel, for compensating for the valve clearance of the exhaust valve (3, 4), can be closed by means of a closure element, and - the abutment, for adaptation of the stop to the position of the valve-clearance-compensation mechanism (11; 11a), is designed in the form of a hydraulic piston/cylinder unit.
