ABSTRACT:
A fuel delivery system for an internal combustion engine has a fuel tank with a piston movably mounted on a guide rod therein to separate the tank into two variable volumes, one for containing fuel and the other for containing pressurized air to act on the piston for compressably pressurizing the fuel, thus preventing fuel vaporization during normal fuel delivery. Pressurized air is provided to the pressure volume by an air regulator or a positive displacement pump, either of which can be controlled by a microprocessor based electronic engine control unit. A filler pipe attached to the tank has at least one anti-expulsion valve therein and pressure interlock means for preventing fuel expulsion through the filler pipe when the tank is pressurized. A pressure accumulator is connected to the fuel line to assist in providing a constant fuel pressure to the engine.
