ETHOD OF AIR Jan. 12, 1932 Patented Jan. 12, 1932 PATENT. orrlc'a MAX GO'IH, OF MUNICH, GERMANY METHOD OF, AND MEANS FOR, INJEGTING FUEL WITHOUT AIR INTO INTERNAL COMBUSTION ENGINES v 1 Application filed February 28, 1928, Serial No. 258,190, and in Germany December 23, 1926.
Applications have been filed in Germany I December 23, 1926, Serial N 0, 102,275 and in jected into an internal combustion engine after the air has been compressed and forced throu h an inlet into a chamber outside the cylinrir, the fuel being then projected, from the cylinder side, against the dividin wall between the said chamber and the cy 'nder, in such manner that the greater part of the fuel is flung back by the said wall, but that a small part enters the said chamber and is ignited, the burning of this fuel serving to drive the remaining air back to the cylinder, where it is energetically mixed with the fuel, and completely burned.
Preferably I arrange that the air chamber referred to is made readily detachable; the dividing wall may be part of the detachable chamber or it may be a separate member, which is adjustable for varying or regulating the angle at which it is struck by the fuel. The opening or openings in the dividing wall may be regulatable.
The air chamber may be made in two parts, provision being made for charging the same easily, for example for the purpose of substituting a chamber of another size. The chamber may be insulated to maintain it at the proper temperature.
The invention is illustrated in theaccompanying drawings in which Fig. l isa fragmentary vertical section of an engine cylinder embodying the invention; Figs. 2 and 3 are vertical sections of two modified forms of means for controllin the entrance of fuel into the ignition cham er and Fig. 4 is a horizontal section through the main control wall z'.
An example of apparatus according to the invention is shown in Fig. 1 showing part of a water-cooled cylinder a, with a c linder head I) and piston 0. The piston pus es the compressed air from the compression chamber e of the cylinder into a globular chamber f'fitted to the cylinder head. The chamber 7 consists of two parts 9 and k, the part it having a neck, which is inserted into a hole in the c linder head, and in which there is. a per orated dividing wall '5. That part 9 is screwed into the cylinder head.
Fuel is injected by means of a water-- I cooled nozzle (13 set obliquely in relation to the wall 2', so that the greater part of the fuel is flung back towards the piston, and is vaporized, making a rich mixture in the chamber e. The small quantity of fuel penetrating into the body of compressed air in the chamber f becomes ignited, and drives out the air, which enters the chamber 6,
where complete combustion takes place. As
the combustion takes place mainly in the chamber e the chamber remains comparatively cool, and there is ittle or no carbonization therein. The perforations of the wall 2' are not liable to become clogged. The maximum temperature occurs closely to the wall 2', which is favorable to the progress of combustion. The combustion diagrams made with reference to various engines operating according to the invention have indicated very satisfactory conditions in regard to combustion.
Fig. 2 illustrates a modification of fuel control means for the ignition cylinder, wherein the perforated wall 11 is adjustably mounted by means of a spindle is associated with the wall at a nonrectilinear angle to the plane thereof, the, spindle passing through a bearing block or boss Z and being rotatable by means of a handle m. Figs. 3 and 4 illustrate a modificatiqn vherein the sizes of the perforations in wall '5 may be controlled by means of the auxiliary perforated wall '5 movably associated with the wall 71 and carried by the spindle passing through the block Z and rotatable by means of the handle m Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. In an internal combustion engine, a cylinder, an ignition chamber at the head thereof and having an opening directed toward said cylinder, means alongside of the cylinder for projecting fuel toward said opening, and means at said opening for allowingpassage of some of said fuel into said ignition chamber but deflecting most of said fuel into said cylinder; said last-named means comprising a perforated wallacross said opening and a 5 flange about said wall. a y
.2. In an internal combustion engine, a cyl-' inder, an ignition chamber at the head thereof and having an opening directed toward said cylinder, means alongside of the cylinder for projecting fuel toward said opening, and means at said opening for'allowing pamage of some of said fuelinto said ignition chamber but deflecting most of said fuel into said cylinder; said last-named means comprising a perforated wall arranged in said opening at a non-rectilinear an 1e to the direction 0 fuel rojection and a ange about said wall.
3. an internal combustion engine, a cylinder, an ignition chamber'at the head thereof and having an opening directed toward said cylinder, means alongside of the cylinder for projecting fuel toward said opemng, a wall at said opening for deflectin most of said projected fuel into said cylin er, and means for adjusting said wall to control the direction of deflection.

In an internal combustion engine, a cylinder, an ignition chamber at the head thereof and having an opening directed toward said cylinder, means alongside of the cylinder for projecting fuel toward said opening, a perforated wall at saidopening for deflecting most of said projected fuel into said cylinder while permitting some of the fuel to enter said ignition chamber, and means for varying the sizes of said perforations.
