ABSTRACT:
A liquid propane injection system for a diesel engine includes a liquid propane fuel tank, a pump, a heat exchanger, a reservoir, and an injector. The pump receives liquid propane from the liquid propane fuel tank, and increases the pressure of the received liquid propane to a level suitable for use by the diesel engine. The heat exchanger receives liquid propane from the pump, and vaporizes the liquid propane. The reservoir stores vaporized liquid propane received from the heat exchanger, and has sufficient storage capacity to compensate for any time lag between instantaneous engine fuel demand and the supply of liquid propane by the pump. The injector receives vaporized liquid propane from the reservoir, and injects the vaporized liquid propane into a combustion chamber of the diesel engine.
