For better automotive fuel economy and environmental quality in an engine, a mixture heating chamber is attached to an engine exhaust manifold. A U-shaped air tube is connected to the mixture heating chamber for supplying heated air to the chamber. A vapor supply fuel line supplies the mixture heating chamber with liquid fuel, the liquid fuel being sprayed from the vapor supply fuel line into a portion of the U-shaped air tube located inside the mixture heating chamber resulting in the vaporization of the liquid fuel. The mixture heating chamber is partially filled with copper pads for fire retarding purposes. The interior of the mixture heating chamber is lined with a felt-liner which retains the liquid fuel present and also acts as a wick. A fuel selector switch allows fuel to be channelled through a vapor supply fuel line and into the mixture heating chamber or alternatively into a main fuel line which connects directly to the carburetor of the vehicle. An outlet tube connects to the mixture heating chamber and allows fuel vapors to travel to a carburetor adaptor located on top of the carburetor.
