UNITED STATES- PATENT OFFICE.
ERNST SCHAEREN, F BERN, SWITZERLAND, ASSIGNOR, BY MESNE ASSIGNMENTS, TO BUSCH-SULZER BROS.-IDIESEL ENGINE CO., 01 ST, LOUIS, -HISSO'U'BJL HIGH-PRESSURE CRUDE-OIL Moron,
Application filed December 22, 1923, Serial No.
This invention relates to solid-injection high-pressure crude oil internal combustion engines of the kind in which the fuel is in: jected in a liquid condition without admix- 5 ture with atomizing air through a cooled auxiliary chamber into an opening which connects this chamber with the engine cylinder.
According to the present invention the opening connecting the auxiliary chamber with the engine cylinder is in the form ofa long narrow passage the length of which is many times its breadth while itis of substantially constant cross section throughout its length.
With this arrangement the hot gases generated under pressure .by the combustion of a part of the fuel in the auxiliary chamber not only considerably accelerates the speed of the unburned fuel, which enters the the auxiliary chamber, buta so atomizes and vaporizes it before it enters the combustion space, whereby the walls of the canal, firstly in consequence of their great length, favor the mixing of the fuel with the hot gases, and secondly, in consequence of their cooling effect, prevent combustion in the canal itself. The mixture of fuel and gases prepared in this maner will be injected into the charge of air in the combustion space of the engine cylinder at such a high speed that it mixes instantly with all parts of the air charge and at the same time burns, thus materially improving the combustion. I
One embodiment of the present invention canal at a good speed after assing through 682,166. and in Switzerland December 30, 1922.
is shown by way ofexample in the accompanying drawing.
space. e is the long, very contracted passage connecting'the working cylinder at with the auxiliary chamber I in which combustion of a part of the fuel takes place. The long, contracted passage 'in a-very simple manner prevents the remaining part-of the fuel from burning before it enters the working cylinder. It has been proved that theprocess of combustion may in this way be considerably improved. The change in cross section from the auxiliary chamber" 9 to the long contracted passage 0 is made gradual in order to facilitate the passage of the hot ases from tihe auxiliary chamber to the wor ing. cylin- I claim In a solid-injection internal combustion engine, the combination with the engine cylinder, of an auxiliary combustion chamber of a width considerably in excess of its length, means for injecting the fuel into said chamber in the direction of its length, a passage, of a length considerably in excess of its width and of substantial y uniform cross-section, connecting the chamber with the engine cylinder, and cooling means effective on said chamber and passage throughouttheir length.
In testimony whereof I have afiixed my signature. ERNST. SCHAEREN.
