  • Process and apparatus for flushing carbon deposits and contaminants from the fuel and air intake systems of an internal combustion engine
    Patent number: 5826602
    Abstract: This invention comprises an improved process and apparatus for flushing carbon deposits and contaminants from fuel and air intake systems of an internal combustion engine. The process includes replacing the regular fuel supply with a mixture of fuel and a cleaning agent, operating the engine at idle speed and introducing another cleaning agent through the air intake system. The first and second cleaning agents can be of the same or different composition. By simultaneously introducing cleaning agents through the fuel supply system and the air intake system, the process combines the two cleaning agents on the surface area around the intake valves, the combustion chambers and other critical areas to remove stubborn carbon deposits.
