DIESEL ENGINE.
.. Application filed August 1,8, 1924. Serial No. 732,857.
To all whom it may concern: 4
Be it known that I, FRANz SoHfim'Z, a citiresiding at Colo e-Mul sia, Germany, have invented certain new and useful Improvements in Diesel Engines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to Diesel engines and especially to engines of the type working without a compressor and having the fuel nozzles arranged laterally of the combus-, tion chamber and oppositely one another.
With Diesel engines of the above-mentioned type, one has tried to obtain a suitable spreading of the fuel jets by arranging the nozzles in recesses of the. cylinder head and by separating the cylinder chamber from the combustion chamber by a contracted portion. This arrangement has the disadvantage of a considerable loss of heat during the compression and the combustion. the one hand, by the air having to be pressed from the cylinder chamber into the combustion chamber, during which movement the airflows at a hi h speed along the cooled walls, and, on the other hand, by .the large surfaces cooled of the recesses arranged n thecylinder head.
Now the present invention has for its primary object to provide an engine of the character stated, in which the combustion chamber has a simple and suitable construction. 'Another ob'ect of the invention consists in giving the uel 'et injected the possibility of a natural sprea ing, i e., a nearly conical spreading, in such a manner as to allow the fuel particles to pass unhinderedly a sufliciently lon way in the combustion chamber, thereby bein thoroughly mixed with the mass of air fore they come into contact and relative influence with the fuel particles injected by the other nozzle. v
With these and other ends in view my invention consists'in the arrangement, construction and combination of the parts to be hereinafter described and'shown In the drawing:
Fig. I is a partial sectional view of the piston and the cylinder of an engine constructed in accordance with the invention,
in the 'acthe piston,
Fig. 2 is a section on the line AA-of Fig 1, ig. 3 is a section on the line B--B of Referrin now to the drawings in particular, a designates the engine cylinder, b the cylinder head, d the piston and f the piston head. Mounted in the cylinder wall near the cylinder head are two or more fuel injecting nozzles c, c. The injecting nozzles c, c are arranged oppositely one another. The piston head has a deep hollow depression 9 increasing in depth from the sides of the piston to its center.
With the arrangement above specified, the mass of air in the combustion chamber is held together. As the cylinder head is simple and smooth and as it possesses but little surfaces cooled, due to the openings of the valves, the losses of the charge by cooling are minimized' Thereby a great partof the combustion heat is directly converted into useful piston work. Therefore the compression of the air may be lower and the ignition is always secured.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is
A Diesel engine without a compressor, comprising a cylinder, a piston movable in the cylinder, a flat cylinder head, a combustion chamber between the cylinder head and fuel injecting nozzles arranged op osite one another and inclined to the axis of the cylinder, the inner surface of the cylinder head being plain andv the top surface of the piston formed with a comparatively deep hollow depressioncon'stituting the combustion chamber, the nozzles directing the fuel into the ends of said depression,
with the depression increasing in width and depth from each nozzle in substantial correspondence with the spread of the fuel delivered by the nozzle, whereby said fuel is permitted a natural spreading and also permitteda substantially uninterrupted travel in the combustion chamber for a thorough mixing with air prior to contact.
In testimony whereof have signed my name to this specification.
FRANZ SCHULTZ.
