ABSTRACT:
A system for improving the fuel economy of internal combustion engines comprises a thermostatically controlled heater located in the fuel line between the fuel tank and the carburetor for heating the fuel to a temperature just below its vaporization temperature. This temperature is controlled to result in a more complete vaporization of the fuel upon entering the carburetor. Another part of the system supplies a fuel additive in the form of a xylene/oil mixture into the carburetor by way of the vacuum advance line to add approximately one ounce of the additive mixture to every fifteen to twenty gallons of fuel. Significant fuel economy has been realized along with a cooler exhaust temperature of the combustion products and a reduction in the amount of pollutants in the engine exhaust.
