摘要

A fuel system adapted for use as the primary fuel source with a conventionally fueled and spark ignited internal combustion engine having a fuel tank for the primary fuel, a fuel pump for the primary fuel for pumping the primary fuel out of the fuel tank; a primary fuel vaporizer connected in communication with the pump and in heat conductive communication with a heat source for vaporizing the primary fuel, a vapor regulator means in vapor communication with the fuel vaporizer and the internal combustion engine for supplying fuel in varying amounts in response to varying conditions of demand on the engine and means connected to the system for sensing the conditions in the system and for switching said conventional fuel supply off and said primary fuel on when the conditions are sufficient for said primary fuel to operate the engine. Further in one embodiment only the primary fuel is used but it is used in liquid phase to inject the liquid primary fuel into the engine to start and operate the engine until conditions are sufficient for use of the vaporized primary fuel when said injectors are shut off.
