(i311. litt-midi) The present invention relates to internal combustion engines and embodies, more specihcally, an improved head for internal combustion en-l gines by means oi which high compression operation can be accomplished in' an emcient manner. The present application relates to subject matter somewhat akin to that described in applicants copending .pplication'Serial No. 694,043, now Patent No. 2,011,642.
ternal .combustion engine heads which are formed in such fashion that a combustion chamber is provided which may conveniently be made with a desired volume and which is oi such character that,lupon the compression stroke of the engine, a combustible mixture is directed into the cham ber and circulates therein with great turbulence.
llt is generally lrnown that satisfactory opera;
tion ci high compression engines can only be had 2c where a head is provided oi such character as to produce a high turbulence of the combustible mixture. In order that a head of this character may be provided, the present invention has been developed and an object thereof is to provide a head for internal combustion engines by means ci which great turbulence is produced in the cornbustible mixture.
A further object oi the invention is to provide a head oi the above character wherein the 30 elements thereof are formed and assembled in such fashion that a head having the desired volume may be formed and assembled edectively. A further object of the invention is to provide a head for internal combustion engines having a 35 combustion chamber so disposed within the head that the compression stroke of the engine forces the combustible mixturethereinto with great velocity and high turbulence. her objects, not specihcally enumerated m abovefwillbe apparent as the invention is described in greater detail in connection with the accompanying drawing, wherein:
Figure 1 is a viewvin section, taken through a `head. constructed in accordance with the present invention.
Figure 2 is a view in section, taken on line 2-2 oi' Figure 1, and looking in the direction oi' the arrows and showing the combustion chamber of i 50 the present invention.
Referring to the above drawing, a head I0 of an internal combustion engine is shown as being formed o f a bottom plate Il and top plate I2. A side plate i3 is welded thereto and an opposite side plate I4 also secured thereto, said plate Il More particularly, the invention relates to in" 'i ally parallel to the plane of the plate il.
the high velocity stream of the combustible mixa ture strikes the lower inside surface of the section being formed with a recess it within which sparit plugs may be received.
Bottom plate ii is formed with a chamber forming recess it and is adapted to be secured to a decir il formed upon a suitable'cylinder block it. A het it spaces the deck il and plate il apart. Cylinder wall it and sleeve ti co.- operate with the chamber forming recess to form a closed cylinder in which reciprocates the piston ci' the engine.
s. fuel mixture inlet pipe it communicates between a suitable inlet manifold and the recess I it while exhaust pipe tt communicates between the recess it and an exhaust manifold. Valve guides it are provided between the top plate i2 and the respective pipes il and it to receive the valve stems oi suitable valves and the above described elements form a hollow head through which circulates a suitable cooling fiu'ld for eiiecting the cooling or the head. f
At the right hand side of the recess it, as viewed in Figure l, an aperture it is formed, this aperture being adapted to receive cooperating combustion chamber sections tt-and ti. Section 2li is formed with apertures it which cooperate with sparh plug bushings i, welded between .as indicated by the dot and dash line tt, the por- `tions so cut away beingremoved land the remainder of the section tt welded at tu to the section 2li. Obviously, an insert could be placed between the sections to adord a larger volume if desired.
The foregoing structure aiiords a combustion chamber which produces high turbulence in the combustible mixture. Upon the compression stroke oi the piston the combustible mixture is directed with high velocity in a direction gener- When 1. An engine head adapted for use with enf gines having cylinder blocks with cylinders formed therein, the head being formed Yof,top, bottom and side plates secured together, one of the side plates having a spark plug recess formed therein,
inlet and exhaust ducts mounted between the top and bottom plates, said bottom -plate being formed with a recess cooperating with the engine cylinder and having an aperture formed therein` at one side of the recess, cooperating combustion chamber 4forming members secured at adjacent edges and mounted between the top and bottom plates, said members being formed with' an opening, the edges of which are secured to the edges of the aperture in the bottom plate, and a bushing extending between one of the chamber forming members and the said recess in the said side plate and forming a spark plug mounting means.
2, An engine head adapted for use with engines having cylinder blocks with cylinders formed therein, the head being formed of top, bottom and side plates secured together, one of the side plates having a spark plug recess formed therein,
the chamber being formed with curved walls and 'i a curved deecting entrance adjacent the aperture in the bottom plate adapted to form a vortex of fluids directed thereinto.
3. An engine head adapted for use with engines having cylinder blocks with cylinders formed therein, the head being formed of top, bottom and side plates secured together, one of the side plates having means therein for mounting a spark plug, inletand exhaust ducts mounted between the top ,and bottom plates, saidbottom plate being formed with a recess cooperating with the enginey cylinder and having an aperture formed therein at one side of the recess, means forming a Icombustion chamber over the engine cylinder and between the top and bottom plates and secured to the edges of the aperture in the bottom plate; the chamber being formed with curved walls and a curved deflecting entrance adjacent the aperture in the bottom plate adapted to form a vortex oi' fluids directed thereinto.
