Abstract
An internal-combustion engine includes a cylinder, a piston reciprocating therein, intake and exhaust ports, a fuel injection nozzle opening into the combustion chamber of the cylinder and an ignition device situated in the top wall of the cylinder. The top wall of the cylinder as well as the piston base oriented towards the top wall each has first and second surfaces being inclined to one another and meeting in a ridge, whereby the top wall and the piston base have an essentially V-shaped configuration when viewed in a sectional plane taken along the cylinder axis. The first surface of the top wall faces and is parallel with the first surface of the piston base and the second surface of the top wall faces and is parallel with the second surface of the piston base. A dished depression is provided in the piston base such that the depression interrupts the ridge and extends on either side thereof, whereby the dished depression is bounded by the first and second surfaces of the piston base.
