초록 ▼

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.

대표청구항 ▼

A propane injection system for a diesel engine comprising: a source of liquid propane; a pump having an inlet and an outlet, wherein the inlet of the pump is connected to the source of liquid propane, wherein the pump is arranged to pump liquid propane from the source of liquid propane through the inlet of the pump to the outlet of the pump, and wherein the pump is arranged to increase the pressure of the liquid propane to the level at which fuel is injected into a combustion chamber of the diesel engine; a heat exchanger having an inlet and an outlet, wherein the inlet of the heat exchanger is connected to the outlet of the pump so that the heat exchanger receives liquid propane from the pump, and wherein the heat exchanger is arranged to vaporize the liquid propane received from the pump in order to provide propane gas at its outlet; a reservoir having an inlet and an outlet, wherein the inlet of the reservoir is connected to the outlet of the heat exchanger so that the reservoir receives propane gas from the heat exchanger, and wherein the reservoir stores propane gas received from the heat exchanger; and, an injector having an inlet and an outlet, wherein the inlet of the injector is connected to the outlet of the reservoir so that the injector receives propane gas from the reservoir, and wherein the injector is arranged to supply propane gas through its outlet to a combustion chamber of the diesel engine.
