ABSTRACT:
A housing located between a conventional carburetor and the intake manifold inlet on a conventional internal combustion engine (such as that used in an automobile) has internal compartmentation to receive a volume of fuel and air mixture from the carburetor and to direct same through an outlet compartment and thence through a conduit to a fuel mixture heat exchanger mounted on the engine. The heat exchanger comprises one or more heat exchanger units each having a closed cylindrical housing with a plurality of closed, individual fuel mixture conduits therein (such as copper tubing). Each cylindrical housing is connected by a conduit, such as a hose, to the hot air exhaust manifold of the engine so that the heated air from the manifold is directed through each housing and around the heat exchanger tubes therein. A filter unit comprises a closed housing which receives the heated fuel through a porous screen baffle and a series of conventional ceramic or foam plastic or other types of filter material. The method comprises the procedure of directing the fuel mixture from the carburetor through the above system and apparatus and back into the engine.
