An internal combustion engine includes a plurality of cylinders defining combustion chambers each having a roof provided in the cylinder head. Each roof is composed of first and second inclined roof surfaces meeting in a ridge line. Two gas intake openings terminate in respective free edges on the first roof surface and at least one gas exhaust opening terminates in a free edge on the second roof surface. Respective gas exchange valves are seatable in the gas intake and gas exhaust openings. A fuel injection nozzle and a spark plug are supported in the cylinder head in a region of the roof. The first roof surface has, adjacent the fuel injection nozzle, a shoulder covering a terminal edge of the cylinders and extending into each combustion chamber. The shoulder has a front face transverse to the nozzle axis. The free edge of the gas intake openings intersects the ridge line.
