Method of using fuel in an engine

Abstract

A method of using a petroleum based fuel in an internal combustion gasoline engine. The fuel has a flash point of at least 5° F. and the fuel is heated, within the engine, to a temperature above 5° F. The electrodes of the spark plugs are continually energized until the electrodes are at a temperature above the flashpoint of the fuel. The electrodes of the spark plugs are then energized intermittently and the fuel is introduced into the heated cylinders to ignite the fuel in the cylinders in a selected sequence. An alternate embodiment of a heated electrode is disclosed.
