VAPORIZEB.

Application filed March 14, 1921, Serial no. 452,053. Renewed June 9, 1524. i

To'all whom it mag concern:

Be it known that I, STANLEY M.UDALE, a

citizen ofthe United States, and residing at Detroit, in the county of Wayne and State of Michigan, have invented a new and Improved Vaporizer, of which the following is Fig. 1 shows diagrammatically the improved means for vaporization.

ternal combustion engine.

Description.

In Fig. A is the float chamber supplying fuel to the fuel nozzle B which delivers into the smaller conduit C. This conduit leads into the larger conduit F at the throat of the venturi D, and B when the rich mixture delivered from O isdiluted by air admitted. by the throttle E into the larger conduit F. The conduit C lies within the exhaust jacket G which ,ther'eby heats the fuel drawn through C and causes vaporiza- ,tionto take place before the fuel issues into D. Compensating means are provided in the form of the tube H which leads from the inlet manifold F to the float chamber A. The outlets L and L of the conduit C adapt the device for use with a four cylinder engine of orthodox design.

In Fig. 2 the same letters without the prime, refer to similar parts in Fig. 1. An inlet valve of the engine is shown at K and the exhaust valve at J.

Operation I On closing the throttle when running slowly considerable suction is developed in the tube C which causes fuel to be aspirated from the nozzle B. In order topreventexcessive fuel being aspirated the compensat- On openingthe throttle the pressure in the float chamber A increases as the vacuum in the inlet manifold F decreases and the increased flow of fuel through the venturi D causes an increased flow of fuel through the vapor tube C" thereby delivering an in creased quantity of vapor, thus compensat ing for the increased amount of vapor ad mitted by the throttle E.

bodying the present invention, by reason of the fact that'the pure air within the intake manifold is first drawn into the engine cylinder and is subsequently followed by Fig. 2 shows the device applied to an in the vaporized fuel and rich mixture from the rich-mixture outlet L. The beneficial results of stratification in increasing mileage are well known, the explanation generally adopted being that it enables a higher mixture which is'sufliciently dilutedby the air to be explosive. The increase in fuel economy thereby obtained is quite large.

1. In a vaporizer internal combustion engines, the combination of a fuel receptacle and a fuel nozzle connected thereto, means for mixing air with the fuel at said nozzle,'an exhaust passage for the engine,;an intake manifold for the engine having. discharge openings and an air inlet, a throttle valve in said air inlet, and

a fuel passage leading from the fuel nozzle through the exhaust passage and then forking, one branch extending to each discharge opening of the intake manifold.

2. In a vaporizer for supplying fuel to internal combustion engines, the combination of a fuelreceptacle and. a fuel nozzle'connected thereto, means for mixing air with the fuel at said nozzle, an exhaust passage for the engine, an intake manifold for the engine having discharge openings and an air inlet, a throttle valve in said air inlet, and a fuel passage leading from the fuel nozzle through theexhaust passage and then forking,one branch extending to each discharge opening of the intake manifold, said intake manifold being formed with venturis at the discharge ends of the branches of the fuel passage. 3. In a vaporizer. for supplying fuel to for supplying fuel to" internal combusion engines, the combination the outlets of the heated rich-mixture passage being located solely in each of the discharge openings of the inlet manifold 16 whereby the outlets for the heated rich mixture are subjected to the full suction of the engine.
