Abstract
A rotary piston internal-combustion engine adapted to operate on a hydrogen fuel gas mixture injected into the intake chamber of the engine through a plurality of spaced intake ports in the engine housing designed to distribute the flow of the fuel gas mixture evenly along the width of the intake chamber. The exhaust gas outlet of the engine includes a plurality of spaced small exhaust ports so as to decrease the dwell of the apex seal of the rotary piston as it passes over the exhaust gas outlet. The fuel supply system to the engine includes a plurality of mixing chambers to ensure thorough and uniform mixing of the fuel gas mixture, an intake header for distributing the fuel gas mixture to the intake ports, and means for preventing back-fire of the fuel gas mixture in the system. Lubricant may be supplied to the interior of the engine through the fuel intake ports in the form of a lubricating vapor in admixture with the fuel gas mixture. In an alternative embodiment, the engine housing is provided with an inlaid strip of hard porous material designed for passage of lubricating oil.
