ABSTRACT:
A multi-fuel gasifier system for internal combustion engines comprising a hollow casing having heat conducting plates therein in thermal contact with a heat exchange duct passing through the casing through which hot exhaust gas passes from the exhaust manifold to the exhaust pipe, a gasifying chamber substantially centrally located within the casing and surrounded by the heat conducting plates and defined by inner wall portions of the plates. An inlet in the casing wall communicates with one end of the chamber and the outlet of the carburetor. An outlet through the casing wall communicates with the other end of the chamber and the intake manifold of the engine. Adjacent the inlet end of the chamber is a first perforated vaporization cap through which fuel-air mixture from the carburetor passes and thereafter contacts a second conically shaped vaporization cap which deflects and sprays the fuel mixture into the vaporization chamber. Downstream of the conical vaporization cap is a second high temperature vaporization section of the chamber which is defined by that portion of the chamber surrounded by the inner walls of the heat conducting plates. An auxiliary fuel tank is provided and is connected to a pre-heating fuel line extending through the heat exchange pipe and coiled around the second high temperature vaporization section of the chamber so that fuel fed through one end is heated before passing to the carburetor inlet where it is mixed with the primary fuel prior to being mixed with air in the caburetor and passed into contact with the vaporization caps and through the gasification chamber of the gasifier. This invention is particularly useful for gasifying lower grade fuels such as diesel oil, or kerosine, for use in IC engines and for mixing lower grade fuels with gasoline for increasing power, efficiency, and economy of operating IC engines.
