In the above-identified patents, cooling apparatus is disclosed which utilizes a gasoline vaporizer connected to the fuel system of a vehicle for vaporizing gasoline in a heat exchanger to cool air or liquid outside the vaporizer. The vaporized gasoline is ultimately fed to the engine of the vehicle for combustion.
The present invention is directed to an improved air conditioning apparatus utilizing a gasoline vaporizer of the type disclosed in the aforesaid patents. One of the problems encountered in experience with the apparatus of the patents has been that excess gasoline in the air-gasoline mixture can disrupt the carburetion and combustion of the engine of the vehicle. Unless the gasoline-air mixture is proportioned properly, combustion may be inefficient resulting in pollution. A great deal of emphasis is being placed at the present time on reducing pollution of the atmosphere by automotive vehicles. Accordingly, one of the primary objectives of the present invention is to improve air conditioning apparatus utilizing a gasoline vaporizer in such a way as to reduce pollution caused by improper combustion.
