APPARATUS FOR SUPPLYING- FUEL TO INTERNAL-COMBUSTION ENGINES.,
Application'led November 25, 1921. Serial No.'517,649.
To alZAw/Lom it may concern.'
Be it known that I, SAMUEL J. PINGREE,
a citizen ofthe United States, residing at the city of St. Louis and State of Missouri, have invented a certain new and useful Improvement in Apparatus for Supplying AFuel to Internal-Combustion Engines, of
which the following is a full, clear, and eX- act description, such as will enable others, skilled inthe art to which it appertains, to make and use the same, reference being had -to the accompanying drawings, formingpart of this application, in which- Figure l is a longitudinal sectional view of my improved apparatus.
Figure 2 is a top plan view of the same.
Figure 3 is a vertical cross-sectional view of the same.
Figure 4 is a longitudinal sectional view 2o of a modified' form.
Figure 5 is a top plan view of the modiiication shown in Figure 4.
Figure 6 is a vertical sectional view of the modification shown in Figure 4.
This invention relates to a new and useful improvement in apparatus for supplying fuel to internal combustion engines, and is designed particularly for use in connection with and 'as an improvement upon the apparatus disclosed in an application liled -by me February 19, 1921, Serial No. 446,333. My present invention relates particularly to the intake manifold of an internal combustion engine such as is commonly used in automotive units such as automobiles, aeroplanes, motor boats, and the like, and consists in dividing the manifold .into cham-K bers so arranged relative to each other as to prevent or mim'mize the action of 40 the fuelized gases as they are rawn into the engine c linders from different portions v of the mani old.
One object of my invention 'is to arrange the chambers inthe manifold in such a way as to prevent or minimize inactive spaces, and hence when the fuelized air passing ented, there will not bea temporary dea cylinder incident to the displacement of air in a dead or inactive airspace. Another object is to construct a manifold in which desired velocities may be created and maintained; and
also to 'construct a manifold in which varyin capacities may bereadily provided for.-
n the drawings, 11 indicates an intake manifold which is secured to an engine casing and through which the fuelized air is drawn into the engine cylinders, two, four,
six or more, in number, as the case may be, from two or more carbureters. These carbureters and their control may be similar to those disclosed in my aforesaid application.
In any event, a carbureter A supplies fuelfold. 5 indicates a partition wall dividing.
the manifold horizontally, this partition wall terminating at or short of the orts 3 and 4 and approximately at the en of the manifold.
6 indicates a port which may communicate with a second carbureter B, and from which fuelized air is delivered into the manifold above the partition wall 5, and which upper chamber or space is likewise in communication with the ports 3 and 4 before mentioned. e A v In operation, the carbureter A in communication with port 2, is used to sup ly fuelized air to the engine cylinders. 'Igus fuelized air is drawn through the ports 3 and 4 alternately and as these ports 3 and 4 'are connected by the chamber above the partition wall 5, constituting a by-pass, it is obvious that a ,partial vacuum created by the suction of the engine cylinders and which tends to produce a surging or pulsating action of the fuelized air, is minimized or prevented by the by-pass, which acts in effect as an expansion chamber or reservoir. The ports 3 and 4 through which the fuelized air is drawn from port 2 are connected by the bypass chamber and consequently the gas in the by-pass chamber is kept active and fuelized and can not become deadnor can it remain inactive for such a eri of time as would cause the vaporize fuel to condense on its walls.
'To facilitate the vaporization of the fuel, which might have a tendency to condense on the walls of the intake manifold, I ymay employ a stove, indicated at 7, through which the exhaust may enter through pipe 8 and be discharged through pipe 9.- This stove for heating the manifold is not absolutely essential, especially in warm climates, but is desirable in colder climates and winter weather.
As disclosed in my aforesaid application, the batteryof carbureters is designed to be operated in such manner that but one carbureter is brought into action in starting the engine. Such a carbureter would ,supply fuelized air to the port 2. Then as conditions require, a second carbureter (or a second and third, etc.) wouldbe brought into action to supply fuelized"` air through the port 6. Y
In Figures 4, and-6, I have shown a vmodified form of my invention in which the manifold is designed for a three cylinder engine or a six cylinder engine. In this form, the manifold 10 is provided with two by-passes 11 and 12 formed by the walls 13 and 14. The outlet portions leading to the engine cylinders are indicated at 15, 16 and 17 and the inlet ports from the battery of carbureters are indicated by the numerals 18 and 19.
The operation of this modication is substantially the same as the one shown in Figures 1 to 3, except that, by the provision of the central outlet port, the fuelized airis drawn in opposite directions from the ends of the manifold toward the center, when certaincylinders are being fuelized, and in this manner the inactive or dead air spaces are avoided. f
It will be readily understood that minor changes in the size, form and construction of the various parts of my improved apparatus for supplying fuel to internal combustion engines can be made and substituted for those herein shown and described, without departing from the spirit of my invention, the scope of which isset forth in the appended claims.
What I claim is: Y
1. An intake manifoldV comprising a single piece tubular member having a partition wall arranged therein for dividing the interior of said member into two compartments, said compartments having inter-comcommunicating with said ports, and having ,exit ports which connect the extremities of said passages, and an independently operable carbureter in operative relation to each inlet port, whereby when a single carbureter is in operation, the passage identified with the other carbureter serves as a by-pass to prevent surging of fueliZed air in the active passageway.
3. An intake manifold comprising a single piece casting provided with an integral partition wall which divides the interior of said casting in two separate passageways, said partition wall terminating short of the exit ports of said passageways thereby establishing communication therebetween independently of the cylinder chamber and said manifold being provided with inlet ports adapted to connect said passageways to the respective carbureters.
bureters adapted to be successively brought into action, an internal combustion engine and its cylinders, a single piece member having individual ducts leading from said carbureters to the chambers in the cylinders of said engine, said ducts having aA point of coniuence adjacent to their point of connectiony to said chambers.
In testimony whereof I hereunto affix my signal ure this 22nd day of November, 1921.
