ABSTRACT:
A vaporized fuel injection system for an internal combustion engine includes a housing adapted to be mounted on the engine and having a vaporizer heat shell therein connected to the engine for receiving hot exhaust gases. Air is compressed by means of compressor blades mounted at the tips of the conventional fan blades for the engine. The compressor blades travel in a shroud whereby the air is compressed and supplied to the housing where it passes over the vaporizer heat shell. A fuel vaporization chamber is formed directly on the heat shell and liquid fuel is injected directly onto the heated shell for vaporizing the fuel. When the engine is cold, the liquid fuel may be injected directly onto glow plugs disposed in communication with the chamber. The heated compressed air is delivered to an outlet passage having a throttle valve therein and the vaporized fuel is delivered through the outlet passage downstream of the throttle valve to provide an air/fuel vapor mixture which is delivered to each combustion chamber of the engine. A liquid coolant is injected directly into each combustion chamber to control the combustion temperature.
