Abstract
A method of using a petroleum based fuel in an internal combustion gasoline engine. The fuel has a flash point of at least 100.degree. F. and the fuel is heated, within the engine, to a temperature above 100.degree. F. The heated fuel is introduced into the cylinders in the engine and ignited within the cylinder to start the engine. The heat source is removed after the engine has become warm. In an alternate embodiment, 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.
