into vaporous ,fuel, superheated fuel vapor,
or gas, and in which either a mixture of two or more different kinds of fuel orone kind of fuel canbe' used, means being provided to change directly from this to another lighter or heavier fuel-oil. r
. This invention difi'ers essentially from those devices (certain carburetors), in which the vaporization of the fuel-oil takes place by heating in the very air sucked inlbythe motor. According to this invention, the va porization of the fuel-oil takes place independently of the air, the fuel oil being mixed with the air after its vaporization. Thus the air can be directly sucked in as cold air through an automatic valve, which, with relation to the feed-pipe of the motor, is disposed parallel to the fuel-oil vaporizer. This does not prevent, however, that a small quantity of air may be sucked into the Va.- porizer together with the fuel-oil, in order to facilitate the passage of the oil through the vaporizer. 7 Furthermore, this invention essentially differs from other devices of this kind in which floats, pumps, or the like, are used, in that the effect of the apparatus here set forth depends directly upon the. suction of the motor, which actuates both the air-valve and (parallel thereto) the vaporizer, causing the fuel-oil to be sucked into the vaporizer, and the fuel-vapor to be sucked from there to the mixing chamber with the air.
The accompanying drawings show, by way I, of example, one form of construction of the said apparatus, which may be directly attached to an ordinary automobile or motor boat.
Figure 1 represents an elevation, partly in .section of one embodiment of this apparatus.
Fig. 2 represents a transverse section of the vaporizer on line 22 of Fig. 1. Fig. 3 represents a vertical transverse section on line Specification of Letters Patent.
' In the central pipe 6 the collecting chamber 7,-a pipe 10 opens Patented J my 4, 1916.
' Application filed February 15,1915. Serial No. 8,834.
3+3 of Fig. 1 showing the duplex cock for centrolling and varying the plural feed-sup- The air-valve 1, which is furnished with a short spring 2, the tension of whichrapidly increasesdurin' the opening movement, is disposed 1n a va ve-casmg' 3, which in a suitable manner, not shown on the drawing,
is connected with the motor or. its various cylinders, and is also 7 connected with the vaporizer by means of a pipe 4, which opens into the valve-casing above the valve 1. The vaporizer consists of a number of pipes 5 disposed in a circle, a central pipe 6, and two collecting chambers 7 and 8, the vaporizer being entirel or partially disposed in the exhaust pipe 9 of the motor. which projects through which, by means of a junction box 11, is con- .nected with pipes 12 and 13 rising from two fuel tanks 14 and'l5. These pipes are regulated together by a hand-actuated member such as a cock 16, with two ways 17 and 18 bored at an angle to each other. The mouth 19 of the pipe 10 opening into junction box 11 has dimensions corresponding to those of the narrowed opening usual in fuel-oil suction-pipes. The pipe 6, surrounding the other end of the pipe 10 is provided with fine air-openings 20.
The motor is started by means of benzin, or some other light volatile oil fed, for instance, from the tank 14.' a The cock 16 is then turned so that the conduit 17 is open and the conduit 18 is. entirely closed. Through the turning'of the motor-shaft, the suction caused thereby will actuate the airvalve 1, which will, however, only be slightly opened, owing to the resistance of the spring 2 and the slow speed, and through the pipe 4., the vaporizer 58, the pipe 10 and the pipe 11,.Wlll cause the liquid to rise in the pipe 10 and flow into the vaporizer. At the same time a slight quantity of air will be pipe 9 will have considerably warmed the pipes 5, and if then the cock 16 be turned so that the conduit 18 is open and the conduit 17 is nearly closed, the suction will also and to a higher degree influence the less volatile and heavier fuel-oil,gpetroleum, crude oil, or the like, in the tank 15, so that a mixture poor in benzin is sucked into the hot vaporizer, where it practically acquires the same vaporizing capacity (owing to the heat of the vaporizer) as that of the benzin when the vaporizer was cold. After a short time the cook 16 can be turned so that the conduit 17 is entirely closed, and only the conduit 18 is left open, and then the motor will continue Working, consuming only'the fuel-oil in the tank 15. By simply turning the cock 16, the driver may now at any time change from the consumption of only heavy, slightly volatile fuel-oil to the consumption of the light volatile oil, or
vice versa, or to the consumption of a mixture of both kinds of fuel-oil in a desired proportion, without in any Way interfering with the running of the motor. Owing to the nathre and adjustment of the spring 2', the supply of fuel-oil is regulated automatically, so that, no matter What is the'number of revolutions, the proportion of the mixture of air and fuel-oil is always correct. Notwithstanding the ready vaporization of the liquid in the vaporizer, the suction will always remain constant in the pipes 10 and 12 or 13, since the vaporization takes place during the transition from a smaller space (the pipe 6 and the collecting chamber 8) to a much greater space (the pipes 5, the
' collecting chamber 7 and the pipe 4), so
that it is not accompanied by any perceptible increases in pressure.
