Abstract
A composition is disclosed which cleans baked-on, carbonized sludges and varnish deposits from the internal surfaces of automobile, motorcycle and truck engines. The product comprises a mutually synergistic solution of selected cyclic compounds, aliphatic amines and water, preferably dissolved in a hydrocarbon or hydrocarbon and aliphatic lower alcohol fuel base. The solution or base product may be placed in a pressure resistant (aerosol) dispenser, and pressurized. When injected into an engine over a period of time, significant removal of deposited contaminants occurs, resulting in smooth and efficient engine operation and lower levels of unburned hydrocarbon fuel, carbon monoxide, and other air pollutants.
