FUEL SYSTEM

The fuel system is designed, to store liquid gasoline and to deliver it to the engine cylinders on the intake strokes in the form of vapour mixed with air. The fuel system must vary the proportions of air and gasoline vapour to meet the requirements of the various operations conditions. The fuel system consists of a tank in which the liquid gasoline is stored, a fuel line, or tube, through which the gasoline can be brought from the tank to the engine, a pump, which pulls the gasoline through the fuel line, and a carburetor, which mixes the gasoline with air. The carburetor is designed to mix each pound of gasoline with 9 to 15 pounds of air under various operating conditions.
