Abstract
Systems and methods provide for cleaning the air intake valves and surrounding areas of an engine. A gravity-fed cleaning-fluid dispenser may feed cleaning fluid into a hose through a metered device that meters a rate at which the cleaning fluid flows into the hose. A second fluid meter connected to a distal end of the hose further meters the rate at which a mixture of the cleaning fluid and air from is dispersed into the running GDI engine. Cleaning fluid may be distributed to the engine at a gradually decreasing rate as a volume of cleaning fluid in the dispenser decreases as the service progresses.
