F. LANG INJECTION ENGINE Jan. 23, 1934.

Original Filed Dec. 1, 1930 l amp/2 I Jnvenzvn Fanz [cl/3g.

Patented Jan. 23, 1934 INJECTION ENGINE Franz Lang, Munich, Germany, assignor to Lanova Aktiengesellschaft, Vaduz, Liechtenstein Original application December 1, 1930, Serial No. 499,223, and in Germany January 21, 1929.

Divided and this application March 20, 1933.

Serial No. 661,730

3 Claims.

My invention relates to a fuel injection internal combustion engine of the type which embodies an air chamber in which fluid is compressed during the compression stroke of the piston and from which the fluid issues during the working stroke of the piston.

This application is a division of my copending application, Serial No. 499,223, filed December 1, 1930, for fuel injection internal combustion engines.

The purpose of the instant invention is to provide an improved construction wherein organized rotary turbulence of the mixture in the combustion chamber is secured.

Instead of providing a plurality of independent air storage chambers, the instant construction provides an annular chamber from which a plurality of passages lead into the combustion chamber, these passages being specially formed and located.

My invention is illustrated in the accompanying drawing, in which Figure 1 is a vertical axial sectional view ofthose portions of the engine with which my invention is concerned; and

Figure 2 is a horizontal sectional view taken on the plane of line 2-2 of Figure l.

The cylinder, formed with a water jacket and composed of one or two parts as convenience dictates, is illustrated at c. The piston, reciprocating in the cylinder, is shown at e and its position illustrated is its topmost position. In the construction shown, the head I) is a separable head, and the fuel nozzle d is mounted axially therein, this nozzle thus injecting fuel centrally into the combustion chamber defined by the piston, the upper end of the cylinder, and the head.

The top of the cylinder casting is provided with an annular groove, concentric with the cylinder, and the underside of the head is provided with a corresponding groove, so that when the head is placed upon the cylinder casting, the annular chamber a is formed.

The chamber a is connected with the combustion space by means of a plurality of regularly arranged passages 1, these passages having their axes disposed substantially tangentially relative cline slightly downwardly, and it will also be noted that the tops of the passagesf are made to coincide substantially with the roof of the combustion space, while the bottoms thereof are made to coincide substantially with the top of the piston when the piston is in its topmost position. The cross section of the passages 1 may be either circular or slotlike in shape.

Upon the compression stroke of the piston, fluid from above the piston is compressed in the chamber a, and upon the working stroke of the piston this fluid issues from the chamber at high velocity, the streams of fluid being so directed as to impart high turbulence to the the combustion space.

Suitable mechanism is of course provided to cause the nozzle d to inject fuel into the combustion chamber at the proper time in the cycle, beginning with the final compression. In the construction shown, the injection from the nozzle it takes placedownwardly into the combustion chamber.

I claim:

1. In combination in an injection engine, a

center of the cylinder, a cylinder head, and a piston opcrating in said cylinder, the piston when in its position of maximum compression defining with the adjacent end portion of the cylinder and the cylinder head a combustion chamber, said cylinder and head being provided with cooperating means defining a concentric air storage chamber and a plurality of passages opening therefrom through the cylinder wall into the combustion chamber substantially tangentially thereof, and

a fuel nozzle for injecting-fuel into the combus 9 tion chamber axially of the cylinder.

2. In combination in an injection engine, a cylinder, a cylinder head, and a pistonoperating in said cylinder, the piston when in its position of maximum compression defining with the adjacent end portion of the cylinder and the cylinder head a combustion chamber, said cylinder and head being provided with cooperating means defining a concentric air storage chamber disposed outwardly beyond the cylinder and extending below the top thereof and a plurality of passages opening from said storage chamber into the combustion chamber substantially tangentially thereof, and a fuel nozzle for injecting fuel into the combustion chamber.

3. In combination in an injection engine, a cylinder, a cylinder head, and a piston operating in said cylinder, the piston when in its position of maximum compression defining with the adjacent end portion of the cylinder and the cylinmixture in tangentially thereof, the'inner ends of said passages corresponding in height to the height of the combustion chamber at the periphery thereof, and a fuel nozzle for injecting fuel into the combustion chamber.
