Augmenter For Compound Compression Engine

摘要

A rotary engine has a first rotary unit and a second rotary unit. The first rotary unit has a chamber containing a remaining compressed air charge. After combustion in the second rotary unit, the resulting second unit exhaust is in fluid communication with said remaining compressed air charge via a second passageway. An injector is in fluid communication with said remaining compressed air charge in the first rotary unit. The injector injects fuel into the mixture containing the remaining compressed air charge in the first rotary engine and the second unit exhaust from the second rotary engine. This mixture is combusted either with a spark or via auto (diesel) ignition. In this way, the engine produces additional useful work by combusting the remaining compressed air charge and additional fuel. Alternatively, the injector described in the first rotary unit may be located in the second passageway. The injector in the first rotary unit or in the second passageway may be selectively activated throughout the engine's mission.
