A heating-chamber is provided for a heating-chamber combustion engine. A piston is provided with a detachable extension on the flat bottom of the piston, which towers upwardly and reaches during the upstoke into a pocket of the cylinder head. The detachable extension has a slit located close to the bottom of the piston. An opening in the cylinder wall is provided, opening a path to the heating-chamber. The path is located near the cylinder head so, that in the highest position of the piston the slit in the detachable extension and the opening in the cylinder wall line up with each other, keeping the opening in the cylinder wall closed in all but the highest position of the piston.
