Abstract
A fuel injection system for engines for improving performance and fuel economy. The fuel injector controlled along with an exhaust port timing control mechanism so that fuel injected into the engine will not pass out of the exhaust port under most engine running conditions. The invention is disclosed particularly in conjunction with a two cycle crankcase compression engine wherein it has particular utility. The timing of the opening and closing of the exhaust port is changed by means of an exhaust control valve that obstructs the exhaust port under certain running conditions so as to delay its opening and closing.
