INTERNAL-COMBUSTION ENGINE.
Specification of Letters Patent. Patented Sept. 20,1921.
Application filed January 25, 1919. Serial No. 272,996.
To allwhom it may concern:
Be it known that I, FRANCIS WALTER GUI- BERT, a citizen of the United States of America, residing at Detroit, in the county of lVayne and State of Michigan, have invented certain new and useful Improvements in Internal-Combustion Engines, of which the following is a specification, reference being had therein to the accompanying drawings.
The invention relates to internal combustion engines and hasv for its object the prevention of accumulation of carbon. To this end the invention consists in the'meansemployed as hereinafter set forth.
The drawing represents diagrammatically a portion of an internal combustion engine to which my improvement is applied.
In the operation of internal combustion engines with hydrocarbon fuel great difliculty is experienced in the depositing of carr bon on the walls of the clearance spaces and also on the valves and valve-seats. Usually the surfaces on which the carbon is deposited are formed of iron or of an alloy contaming a large ferrous constituent. Thus when such a metal is heated its strong aflinfor carbon will cause the breaking down of hydrocarbon vapors in contact therewith, leaving the solid carbon deposit. Further more, after an initial deposit of carbon upon the surface more carbon will be accumulated thereby, soon resulting in pre-ignition, abrasion of the valves and seats and other Q objections incident to the presence of carbon.
The principle underl in the present ine mitial deposit of carbon and consequently to avoid accumulation of the same. This is accomplished by forming the ex osed surfaces of material which has no a nity or less aflinity for carbonthan ferrousmetal; one such substance is copper or alloys containing a relatively large copper constituent; but it is obvious that there may be other materials equally well adapted for the purpose.
It is immaterial to the invention whether the structure having the exposed surface is formed in its entirety of the selected mate rial or whether there is simply a surface coating of such material. In either case the exposed surface will have little or no afiinitfy for the carbon, and thus breaking down 0 the hydrocarbon vapors is avoided. The protecting material may also be applied either to the entire exposedsurface or to only portions thereof which are most liable to receive carbon deposits.
In the drawing I have represented diagrammatically an internal combustion engine, in which A-is the cylinder, B the clearance space or explosion chamber, C, the piston, and D the valves. The walls of the clearance space B are coated with the protectin material, as indicated b the heavy line which may be deposited y any suitable means, such as electroplating, sprayingg etc, In the same manner the exposed end 0 Y the piston and exposed surfaces of the valves ma (go similarly coated, as indicated at F What I claim as my invention is:
1. In an internal combustion engine, a-
wall exposed to carbon gases or'vapors having an exposed lining formed of material with arelatively large copper content.
2. In an internal combustion engine, the combination with an ex losion chamber including a cylinder wal and a piston and valve, of linings u on said wall, piston and valve, exposed to t e carbon gases or vapors and formed of material with a relatively lar e copper content.
n testimon whereof I aflix m signature. .FRAN IS WALTER G IBERT.
