ABSTRACT:
There is disclosed an apparatus for ensuring maximum vaporization of fuel before entry into the intake manifold of an internal combustion engine. The apparatus comprises an extension of the carburetor which separates vaporized fuel from droplets of fuel which remain unvaporized or which are condensed before entering the intake manifold. The unvaporized fuel is collected and subjected to heat generated at the engine exhaust pipe. In particular, heated ambient air heats and vaporizes the unvaporized fuel. The thusly vaporized fuel is then re-introduced into the fuel-air mixture exiting the carburetor, and subsequently enters the intake manifold.
