Another contribution in the field of automotive engineering has been made by the Packard Automobile Company. Its engineers have perfected a device which is at once simple and solves the problem of heating the present low-grade of gasolene to insure complete combustion. The Fuelizer, as it is called, consists of a chamber surrounding the intake manifold, in which a small amount of gasolene is exploded and then drawn into the manifold thus raising the temperature of the gas to a high degree. The gasoline is drawn into the Fuelizer chamber by a small pipe leading from below the butterfly valve, is circulated at high velocity in the chamber by the explosion caused by the spark plug in the chamber, and then goes through a small opening into the manifold where the usual wet and cold mixture from the carburetor is converted into superheated gas which explodes entirely upon ignition.
The benefits of this small device are many. Due to the complete combustion, the danger of unburned kerosene cutting away the lubricant from the cylinder wall, resulting in scoring, is done away with. It is ideal as an aid in cold weather starting; experiments made with a motor banked with snow, the air temperature being 11 degrees Fahrenheit, showed that an instantaneous start was made possible by the Fuelizer, perfect response to the throttle being gained in ten seconds. Another advantage is its automatic action; as the feed to the Fuelizer chamber is below the butterfly valve, suction through the pipe will be strong when the value is closed, as at low speeds, and will be less and less as the valve is opened and good running conditions result. Thus the Fuelizer helps when it is most needed, and is shut off when the motor is hot.
