MOTOR-CAR IFOLD.
Specication of Letters Patent. Patemgqjlsep, 4L, 119170 Application led August 4,- 1913, Serial No. 782,812. Renewed February 8, 1917. Serial No. 147,492.
To 'whom t may concern:
Be it known that I, MARTIN L. WILmAnrs, a citizen of the United States, residing 1n the city of South Bend, county of St. Joseph, v
and State of Indiana, have invented certain new and useful Improvements in Motor-Car Manifolds, of which the following is a` specification.
This invention relates to improvements 1n ymotor` car manifolds, and has among its -salient objects to provide' a constructlon 1n which the heat from theexhaust is utilized to vaporize the fuel in the inlet manifold, v
whereby the fresh fuel is vaporized in the inlet manifold -instead of in the carbureter;
' to provide a construction in which the fresh vaporized gases pass directly to the cylinders v without being subjected to the `condensmg fuel entering the inlet manifold s exposed to a maximum vaporizing surface heated by the exhaust gasesbefore it enters the cylinders; to provide a construction in which the action of a relatively cold inlet manifold; to provide' a construction in which the relatively cool fuelJ and air are lirst mixed in the carbureter and then' completely vaporized in the inlet manifold, just before the gases enter the cylinders; to provide a construction .which is particularly adapted for use with standard types of motor cars and automobiles now on the market, and without necessitating a reconstruction or rie-arrangement ofV the lengines now in use on motor cars; to provide a construction in which the exhaust gases by reason of their heat units being utilized as aforesaid are ldelivered from the exhaust manifolds -to a relatively low temperature; to provide a construction in which 'the inlet and exhaust manifolds are preferably made 1n a single casting; to provide a construction which permits of the use of poor and cheaper fuel than is now practical '1n the present constructions, and at the same time obtains a large efficiency, and in general-to provide an improved construction of the character.` referred to.
The invention consists in the matters hereinafter described and more particularly pointed out in the 'appended claims.
In the drawings- Figure 1 is aside elevation of a four cylder gas engine equipped with my invention' Fig. 2 is a top plan lview of the same;
Fig. 3 is a vertical view, partly in side elevation and dition the crank casing;
the direction of the arrows;
Fig. 5 is a vertical sectional view taken on lines 5-5 of Fig. 1 and looking in the direction of -the arrows.
Referring to the drawings-- l designates the four cylinders of a gas engine, 2 the crank case, 3 the crank shaft, 4: thepistons and 5 the piston rods.4 6 designates the valve stems of the inlet valves and 7 the .valve stems of the exhaust valves. 8 designates the spark plugs, 9 the priming cups. n The foregoing is all of well known construction, and need not vbe further described in detail.
The essence of the present invention consists in the manifold construction proper. It comprises an inlet manifold l0, and exhaust manifold 11, both of which are formed as a single casting, and extend longitudinally along side of each other, being divided bya partition wall 12. The exhaust manifold 11 communicates directly with each cylinder by means of a throat or conduit 13,
partly section, showing in ad-v formed integral with the manifold. It will be understood that there is one of these throats or conduits 13 for each of the cylinders. The inlet manifold 10 communicates with the inlet ports of the cylinders by means of throats or pipes 14. It is to be noted thatthe conduits for the inlet and exhaust manifolds are -alternately arranged and lie in the same horizontal planes. They are formed by staggering the vpartition wall 12 in the manner shown in'the'jdrawings. The intake manifold is connected to'- the carbureter (not shown) by means of an inlet or feed pipe 15. The manifold casting is" secured to the cylinders as followsg-on the cylinders are studs 16 which go through apertured bosses or lugs 17 on the manifold, and are secured thereon by nuts 18.
The operation of the manifold is as follQws;-assuming that the engine is running, the relatively cool fuel and air after being mixed in the carbureter inthe usual manner pass through the inlet pipe 15 into the inlet manifold 10. This fresh charge passing through the inlet manifold is heated by the hot outcoming exhaust gases, and the radiation of the heat unitsfrom the latter gases completely vaporizes the fresh charge of fuel. It is to be noted that this vaporization takes place substantially at the points Where the vaporized charge enters the cylinders. The exhaust gases are of course, cooled by the incoming fresh gases and discharge from the exhaust manifold at relatively low temperatures. y
The invention is not limited to the details of construction shown, except as set forth in the appended claims.
I claim as my invention: f v y 1. In a gas en e, the combination with a plurality of cy inders, of a manifold construction therefor comprising inlet and exhaust manifolds lying along side of each other and divided by a-partition Wall, conb duits leading alternately from the intake and exhaust manifolds tothe inlet and ex'- haust ports of the cylinders, lying substantially in the same horizontal planes and formed by staggering said partitiomwall.
2. In a gas engine, the combination with a plurality of cylinders, of a manifold construction therefor comprising inlet and exhaust manifolds lying alongside of one anothery and divided by a single partition wall, conduits arranged in. pairs adjacent each other and leading alternately from the intake and exhaust 'manifolds to the inlet and exhaust ports'of the cylinders, said conduits .lying in the same horizontal planes and forlrlned by staggering the single partition Wa 4. The combination with an internal combustion engine provided with a plurality of cylinders having valve controlled inlet and exhaust ports, of a manifold associated withv thecylinders and arranged at one side of the same and comprising elongated inlet and exhaust chambers lying along side of each other, the major portions of their Walls being non-opposed and exposed to the atmosphere and their minor ortions throughout the major portions of t eir length being in close-juxtaposition, whereby heat will be transferred from the exhaust to the mixture Within the inlet chamber, said manifold having a plurality of inlets and outlets leading from the non-opposed sides, of said chambers, said inlets and outletsbeing substantially in alinement and coperating with the valu controlled inlet and exhaust ports of the engine cylinders.
