Abstract

The invention relates to an internal combustion engine (M) comprising a first cylinder to be operated when fuel is supplied, a second cylinder to be operated without fuel being separately supplied thereto, and an overflow connection (20; 21) that is formed between the cylinders and is fitted with a blocking member (22, 23) which can be maintained in an open position during the power stroke of the first cylinder. The pistons (10-12) in the cylinders move substantially in a synchronous fashion in relation to the top and bottom dead center, the dead volume (17) of the second cylinder is smaller than the dead volume (15, 16) of the first cylinder, and the second cylinder encompasses a discharge valve (27) that is to open during the compression phase of the first cylinder. According to the invention, the discharge valve (27) of the second cylinder can be closed by the piston (12) thereof before the top dead center is reached such that a compressive force which is applied when the blocking member (22, 23) is opened can be generated in the second cylinder.
