An internal combustion piston engine based on a four-stroke process, including a crankcase in which at least one cylinder/piston assembly is arranged, a piston is guided via a connecting rod connected to a crankshaft, at least one cylinder head for closing the cylinder, each of whose intake and exhaust channels are controlled by at least one intake valve and one exhaust valve (11, 11a). The intake and exhaust valves are actuable by a rocker arm (2, 3) or a finger lever driven by a camshaft, the rocker arms or finger levers are guided on at least one axle (4). A brake control device is provided including at least one hydraulic adjusting piston that engages a component that opens at least the one exhaust valve additionally and intermittently, a pressure source for a hydraulic fluid is associated to an adjusting piston, and the supply to the adjusting piston is controlled by at least one electrically operable switching valve (21). A compression relief cam per cylinder/piston assembly of the internal combustion piston engine is arranged on the camshaft, with the cam being operatively connected to a compression relief rocker arm (1) or a compression relief finger lever, and the adjusting piston (15) is configured as a coupling pin for connecting the compression relief rocker arm (1) or compression relief finger lever, to the rocker arm or arms (2) or finger lever or levers of the exhaust valve or valves (11, 11a). |
