An alcohol fuel and apparatus for modifying a conventional diesel or detonation engine having an intake manifold. The engine modification apparatus consists of a fuel delivery system and a fuel injector having a probe which projects into the airstream of the intake manifold. A fuel regulator of the fuel delivery system supplies fuel to the injector under pressure. The fuel pressure changes with changes in the load condition and operating speed of the engine. Fuel supplied to the injector is fumigated into the airstream of the intake manifold through a tapered needle valve. The metering position of the tapered needle valve is adjusted in the injector also in response to changes in the load conditions and operating speed of the engine. By selecting the taper of the needle valve, the response of the regulator, and the response of the injector, the horsepower of the engine can be significantly increased using a hydrous alcohol fuel mixture containing between 30% and 60% water by volume. A small quantity of synthetic oil is added to the hydrous alcohol fuel for enhanced lubrocity and fumigation and for reduced corrosive effect. |
