Engine cleaning system

Abstract

An internal combustion engine purging system cleans out deposits of carbon and other substances that accumulate over time in the fuel system by delivering a mixture of fuel and cleaning solution into the fuel intake ports while the engine is running, so that the engine pulls the mixture through the carburetor jets or injectors. This purging system is characterized by its virtual universal application with substantially any commercially produced gasoline or diesel engine. It is in part comprised of two separate but overlapping systems, one for gasoline and one for diesel, which are selectable by the operator. Engines as small as a lawnmower and as large as a locomotive diesel can be purged by the system due to a combination of a high-capacity diesel pump motor which can deliver two gallons of fuel per minute at a pressure of 50 pounds per square inch, and a flow control system which can meet the needs of substantially any engine in terms of the flow rate and pressure of the fuel that it requires for its fuel intake, and a separate gasoline pump.
