Abstract

The present invention relates to a combustion engine which incorporates an engine braking function. The combustion engine incorporates a camshaft (1) with a peripheral guide surface (2) which includes a first cam (3) which, when a non-compresssion state prevails in the combustion chamber (20), is designed to initiate a control movement for opening the exhaust valve (18), and a second cam (4) which, when a compression state prevails in the combustion chamber (20), is designed to initiate a control movement for opening the exhaust valves (18, 19) against a compression pressure in the combustion chamber (20) so that engine braking is provided, and a motion-transmitting mechanism (5-17) designed to transmit said control movements. The motion-transmitting mechanism (5-17) incorporates a first clearance (11) for eliminating the action of the second cam (4), and a variable-length clearance-adjusting device (13) which, in an engine-braking state, is designed to bridge a second clearance (14) in the motion-transmitting mechanism (5-17.
