Abstract
Abstract Hot water is transmitted from an automobile's cooling system to a fuel vaporizer wherein it is utilized to heat gasoline to a vapor state. Air is drawn into the fuel vaporizer utilizing carburetor vacuum and is added to the vapor and drawn into the carburetor. Vaporized fuel and outside air are mixed in a separate dry vapor section within the vaporizer and the amount of air allowed to enter the fuel vaporizer is controlled utilizing a valve system. In this manner, the fuel-air vapor is more efficiently burned in the engine and improved gas mileage is achieved.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
152 words
A fuel vaporizer system comprising: a vapor compartment for vaporizing liquid fuel; a heat exchanger disposed within said vapor compartment; a liquid fuel supply means coupled to said vapor compartment; input means for introducing ambient air into said vapor compartment, said input means including an air manifold having a plurality of small apertures disposed in the upper surface thereof and a plurality of larger apertures disposed in the lower surface thereof; a check valve located at said input means for ceasing the introduction of ambient air into said vapor compartment in response to positive pressure therein; and a vapor mixture compartment located above said vapor compartment having a plurality of apertures located therein to permit entry of vaporized fuel from said vapor compartment, a control valve for selectively controlling the entry of ambient air into said vapor mixture compartment, and vapor outlet means adapted to be connected to an internal combustion engine.
Claim 2
Dependent Claim
