ABSTRACT:
A motor vehicle internal combustion engine having a pair of heat risers on the exhaust manifold and a plenum chamber positioned about the carburator fuel reservoir. Air from one of the heat risers is directed into the front of the air cleaner assembly. Air from the other heat riser is directed into the plenum where it preheats the fuel in the reservoir, and then exhaust into the air cleaner assembly where it is mixed with the air received from the first heat riser. Significant savings in fuel consumed by the engine have been noted by thus preheating the air and the fuel without vapor lock occurrences.
