ABSTRACT:
This specification teaches a method of operating an internal combustion engine having combustion chambers on a methanol fuel. In general, the method teaches the steps of heating the fuel to vaporize at least a portion thereof, thereafter heating at least a portion of the vaporized fuel to a decomposition temperature. At least a portion of the vaporized methanol fuel at the decomposition temperature is passed over a catalyst selected from the group consisting essentially of a palladium catalyst, a platinum/palladium catalyst, and a platinum/rhodium catalyst, thereby to decompose at least a part of the vaporized methanol fuel into hydrogen and carbon monoxide. The vaporized methanol fuel, along with the hydrogen and carbon monoxide, are injected into the combustion chambers of the internal combustion engine along with oxygen and, if desired, additional methanol fuel to be burned in the combustion chambers. The fuel and decomposition products thereof are burned within the combustion chambers and exhaust gases produced thereby exhausted from the combustion chambers. Additionally, the method teaches that the exhaust gases may be used in the heating of the fuel to its vaporized state and then to its decomposition temperature.
