Abstract:
Disclosed is a liquefied petroleum fuel system for internal combustion engines that improves fuel economy by mixing vaporized liquid petroleum gas (LPG) and ambient air at substantially equal random kinetic energies. The system maintains a certain vapor pressure in the LPG tank and delivers the LPG in a gaseous phase to an LPG burning device at a set pressure and temperature. The cycle repeats as necessary to maintain the desired pressure in the tank.

Claim (Index 2):
The liquefied petroleum fuel system of  claim 1  further comprising:\n wherein the pump is an electric pump; \n a pressure sensor that is integrated with the pressure switch, wherein the pressure sensor monitors the vapor pressure in the fuel tank and activates the electric pump whenever the vapor pressure in the fuel tank is below the set pressure so that said pump (a) circulates liquid propane through the first line, the second line, and the heat exchanger wherein heat from engine coolant is used to vaporize the liquid petroleum gas and (b) returns the vaporized liquid petroleum gas to the fuel tank through the third line so that liquid petroleum gas and vaporized liquid petroleum gas occupy the fuel tank; and \n wherein the pressure switch eliminates power to the electric pump to stop the circulation of liquid propane and opens the fourth line from the fuel tank for vaporized liquid propane in the fuel tank whenever the vapor pressure in the fuel tank is above said set pressure; and, \n wherein the set pressure is in a range of approximately forty to approximately one-hundred pounds per square inch; and, \n wherein said engine has 16.1 brake horsepower per hour and a cold start Carbon Dioxide Emission of 752.3 grams per brake horse power hour.
