Improvements in a gas powered engine. Said improvements include use of a piston with a fixed piston arm that extends through a seal in the lower portion of the cylinder. In this pro-posal of a four-stroke engine, the down chamber is used as supercharger for the upper chamber cylinder engine. In this proposed two-stroke en-gine the down chamber is used as a compressor chamber and the compressed air passes to the up-per chamber. The piston arm operates on an ellip-tical crank that drives the output shaft. Valves that move air and exhaust into and out of the pistons are lifted by a cam located on the crank. A unique oil injector passes oil between the rings when the piston is in at the bottom of the stroke.

Linvention concerne des améliorations dun moteur essence. Lesdites améliorations comprennent l'utilisation d'un piston doté dun bras de piston fixe qui s'étend à travers un joint dans la partie inférieure du cylindre. Dans ce projet de moteur à quatre temps, la chambre inférieure est utilisée comme compresseur volumétrique pour le moteur doté dun cylindre à chambre supérieure. Dans le moteur à deux temps proposé, la chambre inférieure est utilisée comme chambre de compresseur et lair comprimé passe dans la chambre supérieure. Le bras de piston fonctionne sur une manivelle elliptique qui entraîne l'arbre de sortie. Les soupapes qui déplacent l'air et léchappement dans et hors des pistons sont soulevées par une came située sur la manivelle. Un injecteur dhuile unique fait passer lhuile entre les segments lorsque le piston est à lintérieur au fond de la course.
