ABSTRACT:
An easily installed modification is disclosed for selectively supplying fuel and air to all or only a fraction of the rotors in a multirotor rotary engine for substantially increasing the fuel economy efficiency of the engine while reducing the emission by-products produced by the engine. The modification system includes means for assuring normal engine idling and for assuring adequate lubrication of rotors during time periods when such rotors are not supplied with fuel or air for combustion.
