ABSTRACT:
A fuel air injection system for a two cycle crankcase compression internal combustion engine wherein a pressure accumulator is provided in the injector and the accumulator is charged with a compressed charge from the combustion chamber into which the injector injects during a phase of operation. In one embodiment of the invention, the accumulator chamber is charged during a compression stroke when ignition does not occur and in another embodiment of the invention, the accumulator chamber is charged during the same stroke of the engine when ignition occurs.
