Engine with two port fuel injectors

The invention provides a system for an engine, comprising of a cylinder located in the engine, a first port injector for injecting a first fuel into the cylinder, and a second injector outside the cylinder for injecting a second fuel into the cylinder. In this manner, the improved air inlet cooling...

Beschreibung
Zusammenfassung:	The invention provides a system for an engine, comprising of a cylinder located in the engine, a first port injector for injecting a first fuel into the cylinder, and a second injector outside the cylinder for injecting a second fuel into the cylinder. In this manner, the improved air inlet cooling operation can be realized so as to increase compression and/or increase pressure while reduce the engine knock limit, and the weakness of the direct injection system can be also avoided. In addition, by employing a plurality of injectors, one of the injector can be designed to inject when the valveis open while the other injector can be designed to inject when the valve is close, so that the air inlet cooling can be improved.
