An internal combustion engine has a camshaft (23) which acts on inlet and outlet valves (5, 7), wherein the lift curve (EV, AV) of the inlet and outlet valves (5, 7) is determined by the shape of the cams (24, 25) of the camshaft (23). Arranged on the camshaft (23) is an additional auxiliary cam which acts on the outlet valve (7), as a result of which a phase-offset auxiliary lift curve (AVz) is imparted to the outlet valve (7).
