G. M. BALL INTAKE MANIFOLD Filed May 11 1925 Guy Patented Nov. 30, 1926.
GUY M. BALL, OF DAYTON, OHIO.
INTAKE MANIFOLD.
Application filed May 11,
This invention relates in general to internal combustion engines and more particularly to intake manifolds adapted for use in connection with such engines.
This application is on an invention constituting an improvement in my manifold as disclosed in my Patent No. 1,454,596.
It is an object of this invention to provide means for positively insuring the circulation of fuel gas through my intake manifold and more thoroughly breaking up the fuel conibustion ingredients.
Other objects will appear in the accompanying specification and claims and will be disclosed in the drawings in which- Fig. 1 is a side elevation, partly in section of my device as applied to internal combustion engines;
Fig. 2 is a similar view of a modification thereof.
Referring with greater particularity to the drawings, the internal combustion engine 1 is provided with a carburetor 2 and a branched intake manifold 3, each branch leading to a second manifold intake part l adapted to supply fuel to half the engine cylinders employed. The manifold section 4c, is, as shown, substantially elliptical in de sign being so constructed at its lower portion as to provide a restricted internal diameter, as shown at 6, the purpose of which will be hereinafter described. The manifold section 3 is adapted to extend into the lower portion of the manifold section 4 and tcr1ninate in an outlet 5 at a point approximately the point of the smallest cross sectional area of the restricted portion 6 and in a direction parallel to the lower portion of the manifold 4 at this point. At 7 are shown suitable inlet pipes for the admission of the fuel from the intake manifold into the cylinder's. At 9 are shown suitable heating elements mounted on the manifold 3 and adapted to heat the gases before their entrance into the cylinders.
From the foregoing, my device seems to operate as follows: The fuel leaving the 1923. SeriaI NO. 638,311.
outlet 5 of the manifold 3 at a point at approximately the most restricted part of the intake manifold 1, will act as an injector and insure the circulation of gases within the intake manifold in the direction indicated by the arrow. The pulsation in the intake manifold will thus be avoided.
In the embodiment of my device, as shown in Fig. 2, similar numerals refer to similar parts. A slightly modified form of my in vention is illustrated in Figure 2.
The force of gases rushing through the manifold 3 pass through the venturi 5 and the aerodynamic forces created thereby in sure the motion of gases through the intake manifold extension in the direction as indicated by the arrow.
Having thus described my invention what I claim is- 1. In an internal combustion engine, an intake manifold comprising two sections. one section being essentially elliptical in shape and adapted to conduct the fuel to the engine intake ports, said section being pr Vided with a port-ion having restrictive interior cross sectional area, the second section being adapted to extend into the interior of said first named section and having its outlet at approximately the smallest cross sectional area of the first named section, for the purpose described.
2. In an internal combustion engine, an intake manifold comprising two sections, one section being essentially elliptical in shape and adapted to conduct the fuel to the engine intake ports, said section being provided with a portion having restrictive interior cross sectional area, the second section being adapted to extend into the interior of said first named section and having its outlet at approximately the smallest cross sectional area of the first named section, and a heating element around said second named section.
In testimony whereof I affix my signature.
GUY M. BALL.
