ABSTRACT:
A hot slipstream from the exhaust of an internal combustion engine is used directly, that is without valving it, to heat and vaporize fuel as it is sprayed from the fuel nozzle of a carburetor having a booster venturi above the throttle plate, provided the ratio of the volume of slipstream to the volume of exhaust gases is self-regulated within narrow limits at all times during the engine's operation, in accordance with the physical considerations governing gas flow. The main jets of a conventional carburetor may be changed to provide decreased flow of gasoline by about 10% to give better mileage without sacrificing performance of the engine, and without adversely affecting the exhaust emissions which are otherwise controlled by a conventional emission control system.
