, UNITED STATES- PATENT; OFFIC WHEELER G. LOVELL 'AND THOMAS A. BOYD, OF DETROIT, MICHIGAN, ASSIGNORS TO GENERAL MOTORS RESEARCH TION OF DELAWARE I CORPORATION, OF DETROIT, MICHIGAN, A CORPORA- METHOD AND MEANS FOR EEMOVING CARBON DEPOSITS No Drawing.
This application relates'to the removing of carbon deposits from internal combustion engines, and its principal objects are to provide chemical compounds which will readily loosen the deposits and a method which will These aliphatic amines include the primary amines of which isoamylamine, ethanolamine, benzylamine, ethylene, diamine monohydrate, and hydroxyethylamineare examples; the secondary amines of whlch di-isomylamine and diethanolamine are examples, and the tertiary amines of which tri-lsoamyl amine and triethanol amine are examples. We use those aliphatic amines Wl11Cl1 boil above 150 F. to keep the carbon remover 1n the liquid state in a hot engine because the heat accelerates the solvent action of the liquid. Optimum conditions in a water cooled engine are to heat the parts to ]11St below the boiling point of water and employ an a11- phatic amine which remains liquid at that temperature.
By way of a specific example, we may run an engine until it is hot, then introduce into each cylinder about a tablespoonful of hydroxyethyl amine and let the engine set, preferably for an hour or more. After the engine is started the loosened carbon is blown out the exhaust. The. metal surfaces can also be cleaned by wiping the deposit oil".
The carbon remover dissolves in the binder of the carbon coating, or the two may be mutually soluble, causing the binder and the deposit as a whole to swell. The heat developed when the engine is started drives the solvent and some of the binder away leaving asomewhat porous and disintegrated mass which is lightly held together and the rush of Application filed August 24, 1928, Serial No. 301,942.
Other compounds, such as aniline, furfurerr etc., which have a solvent action on varnish, may be employed with the aliphatic amines.
We clai. I. The process of cleaning carbon deposits from an ljnternal combustion engine which comprisesheating the carbon coated parts,
placing on; the carbon deposit an aliphatic amine which boils above 150 F., and removing the deposit. a
2. The process of cleaning a carbon deposit from an internal combustion engine which comprises running the engine until the carbon coated parts are heated, dissolving into the binder of the deposit an aliphatic amine which boils above 150 F., and blowing the loosened carbon out of the engine exhaust.
