ABSTRACT:
A heating chamber seal is provided for a heating chamber combustion engine. A piston is provided with an extension on the flat bottom of the piston which towers upwardly and during the upstroke reaches into a pocket of the cylinder head. The extension has a slit at the bottom of the piston, an opening in the cylinder wall, opening a path to the heating chamber which is located near the cylinder head so that in the highest position of the piston the slit in the piston 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.
