fETlEL-SAVING DEVICE.
Application filed May 31, 1927, Serial No. 195,492, and in Japan March 11, 1927.
This invention relates to new and useful. improvements in fuel. systems, for internal con'ibustion engines, and one of the objects of the invention is to supply a quantity of steam to the fuel charge from the carbureter, which steam is generated by heat contained in the burnt gases.
Another object of the invention is to supply a quantity of auxiliary atmospheric air to the fuel charge from the carbureter.
A further obj ect of the invention is to highly heat the fuel charge to form an extremely effective explosive mixture on itsway to theintake manifold.
A still further object is to intimately intermix and break up the fuel. charge into an extremely effective explosive mixture on its way tot-he intake manifold. v
The accompanying drawings illustrate the invention applied to internal combustion engines of motor vehicle by way of example, in which:
Fig. 1 is a front view partly in. section.
Fig. 2 is a side view partly in section, and r 3 is a sectional view showing steam inlet and auxiliary airinletin detail.
Referring to the drawings, we provide an intake manifold 1 and a mixingchamber 2 cast in one body, both coi'nmunicating 30 through a port 3. The intake manifold 1 is of the usual type adapted to be applied to existing types of motors in place of conventi onal intake manifold generally used. The mixing chamber 2 is preferably of a hollow spherical form and constructed. in two sections and connected together by belts or other suitable fastening devices, although it may be of any suitable forms and constructed in one body.
l Vithin the mixing chamber 2 is enclosed a heater 4 with an inlet duct 5 and an outlet duct 6. This heater substantially of hemispherical form with a depressed flat top, and is of such dimension as to provide an ample space on the top for causing the explosive mixture to be intimately intermingled and providing suitable heating chamber between the wall of the mixing chamber and the wall. of the heater as shown in Fig. 1, but it may be of any suitable forms corresponding to the formof the mixing chamber, the top being flatly depressed for the above said. purpose. An elbow 7 is connected to the exhaust 1n animold 8 by welding or other suitable means and provided with a regulating valve 9, whereby any desired heating of the explosive mixture may be attained so that it may be adjusted for changes in the weather conditions and different climatic conditions. The inlet duct 5 of the heater l connected with the elbow 7 by suitable means and the outlet duct 6 opens to atmosphere through suitable dischargepipe connected thereto, so that a portion of the burnt gas passing through. the exhaust manifold 8 from the motor will. enter into the heater 4 through the elbow 7, the regulating valve 9 and the said inlet duct, and will heat the explosive mixture in the mixing chamber 2, and then discharge to'atmosphere through the said outlet duct and the discharge p1pe.
Themixing chamber 2 is provided. at the bottom with an inlet conduit 10 extending downward and having a lateral branch 11 for the carbureter connection.
The steam and the auxiliary air will be introduced into the inlet conduit- 10 through any suitable means to intermixwith the fuel charge from the carburetor. In the example illustrated in Figs. 1 and 3, at the under side of the inlet conduit 10 is formed a casing 12 to which a cover 13 is tightly screwed. The cover 13 is provided with. an internally extending tube 14 with a number of perforations 15 at the under portion thereof.
A steam inlet 16 witlra regulating valve 17 and an internally extending tube 18 is connected to the cover 13 to connnunicate with the inlet conduit 10 by suitable means.
A steam generator 19 of suitable construction is so attached to the exhaust manifold 8 as to be heated by the burnt gas passing through the said exhaust manifold, and is supplied with some quantity of water through. a pipe 20 from a tank (not shown) located in suitable position and provided with such suit able means as a float control device in order to keep the water level constant, that is, to keep a constant water head. The steam gen erated in the steam generator 19 will enter into the inlet conduit 10 through a pipe 21, a three-way cock or valve (not shown) interposed in the pipe line or branches thereof and adapted to establish the pasage of the steam to the inlet conduit 10, or to discharge in at.- mosphere the steam and the steam inlet 16.
An auxiliary air inlet 22 with a regulating valve 23 is connected to the cover 13 to communicate with the casing The atmospheric air will enter into the casing 12 the inlet conduit through the perforations and the space 24 between the wall of the I internally extending tube 18 of the steam inlet 16 and the wall of the internallyextending tube 14 of the cover 13.
Thus, the above described means are adapted to introduce the steam and auxiliary aim-both at the'same time or either one as desired,iinto.the fuel charge'from the carbureter.
1 From the foregoing description, the operas tion and functionsof the improved fuel savcarbureters.
ing, device Will "be understood. With the heating and mixing system according to the invention, it will be seen that the fuel charge from the carbureter will be highly heated by means of the heater with the steam and, the
explosive mixture even with Well designed The fact .that the burnt gas passing through the exhaust manifold is ejected into atmosphere through the heater will have the same eflectas an increase of the diameter of the exhaustinanifold, so that back pressure in the motor cylinder will be reduced. Further, the carburetor Will be heated ,by radiation and conduction of heat from the' mixing chamber, the carbureter being connected adjacent the mixing chamber, so that the operation of the carbureter will be considerably im )roved. This improved system is extreme y economical and improvesoperation of the motor, more particularly starting of the motor, and may he applied to any type of motors now generally in use.
It will of course be understood that numerous details of the construction shown may be altered without departing from the spirit of this invention as defined by the appended claim.
Having now particularly described and ascertained the nature of our said invention and in what manner the same is to be performed, we declare that what we claim is:
A fuel saving device for internal combustion engines comprising an exhaust manifold an intake manifold, a heater substantially of hemispherical form with a flat top, a mixing chamber substantially of spherical form in outline connected to said intake manifold and enclosing said heater therein, means for supplying steam to the explosive mixture in the inlet duct of said mixing chamber and means with a regulating valve for drawing supplementary air into the inlet duct of said mixing chamber.
In testimony whereof We afiix our signatures.
