ABSTRACT:
Several embodiments of fuel injected internal combustion engines having improved injection and induction systems for improving performance, particularly at low speeds. In each embodiment, the injection nozzle is disposed in a position so as to have its discharge spray directed against a throttle valve of the engine so as to improve fuel vaporization at low engine speeds. In each embodiment, an auxiliary induction system is also provided having a relatively small cross sectional area. The idle and low load charge requirements of the engine are supplied through this auxiliary induction system to further improve vaporization and also to promote turbulence in the chamber at the time of combustion. The fuel injection nozzles of the embodiment are disposed so that their discharge spray either intercepts the inlet opening to the auxiliary induction system or is diverted by the throttle valve toward this opening. In one embodiment of the invention, two fuel injection nozzles are employed which discharge alternately.
