ABSTRACT:
A fuel delivery system employs an evaporation chamber which preheats the fuel by means of exhaust gases prior to injection of the fuel into a carburetor. A solenoid valve operates to control the amount of fuel introduced into the evaporation chamber and the valve is controlled in operation by means of a selector circuit which controls the operation of the valve and hence, the flow of fuel according to the speed of the engine, the pollutant content of the exhaust gases, and the temperature at which the engine is operating at.
