ABSTRACT:
The method of cleaning internal combustion engine fuel injector structure, valves and combustion chambers, and employing a canister containing a liquid mixture that includes engine fuel and injector cleaning solvent, the steps that include charging pressurized gas into the canister to a selected high-pressure level; communicating the interior of the canister with a passage extending to the injector structure and operating the engine to provide pressurized fuel discharge delivered to the passage; terminating operation of an engine fuel pump; continuing operation of the engine and flow of the mixture in the canister to the injector structure until the mixture in the canister depletes; and re-charging pressurized gas into the canister to a selected high-pressure level, and continuing flow of the mixture to the injector structure while the engine is running.
