The method of cleaning a fuel injection type internal combustion engine wherein the engine has a block, a combustion chamber, fuel injectors operatively connected to a fuel tank and a fuel pump, an engine starting mechanism and a fuel supply line connecting the fuel tank and the fuel injectors with the fuel pump imposed in the fuel supply line, and a fuel return line connecting the fuel injectors and the fuel tank, wherein the fuel pump is rendered inoperative and the fuel return line is blocked. A combination of fuel and cleaning fluids is imposed under pressure into the fuel supply line. The engine is then started and operated on the supply of fuel and cleaning fluid which have passed through the fuel injectors. After the engine has been operated for a period of time, perhaps 15 minutes or so, the engine is shut off, the fuel return line is unblocked, and the fuel pump is restored to its original condition. The apparatus of cleaning a fuel injection-type fuel combustion engine is disclosed including a pressure tank or container having an inlet port for air under pressure. The tank has a pressure gage and an outlet pipe which leads to a filter mechanism. An outlet pipe from the filter mechanism has a fitting which is adapted to be connected to the fuel supply line of a fuel injection-type internal combustion engine.

The combination of an injection-type internal combustion engine having an engine block, a combustion chamber in said block, a fuel injection system including a fuel manifold and fuel injectors, a fuel tank, fuel supply return lines extending between said engine and said fuel tank, a fuel pump in said fuel supply line; and a device for cleaning the injection system of said engine, comprising, a closed container having a fluid inlet port, an air valve in the upper portion of said container for introducing air under pressure into said container, a fluid exit port in the lower part of said container for removing fluid from said container, fluid in the lower part of said container comprising a mixture of engine fuel and engine cleaning solvent, means connecting said fluid exit port and said fuel injection system, compressed air in the upper portion of said container in direct contact with said fluid for directly forcing said fluid into said injection system to operate said engine, said fuel pump being disconnected from said fuel injection engine, said closed container being free from connection with said fuel pump and said fuel tank so that only said mixture flows directly from said closed container into said injection system. The method of cleaning a fuel injection system of an injection-type internal combustion engine having an engine block, a combustion chamber in said block, a fuel injection system including a fuel manifold and fuel injectors, a fuel tank, fuel supply and return lines extending between said engine and said fuel tank, and a fuel pump in said fuel supply line, comprising, disconnecting the fuel tank from said fuel injection system by rendering said fuel pump inoperative, partially filling a closed container with a mixture of fuel and cleaning solvent so that an air-filled space exists in said container above said mixture, connecting the portion of said container containing said mixture to said injection system, charging said space in said container with compressed air to impose pressure directly on said mixture substantially equal to the normal operating fuel pressure provided by said fuel pump, to cause said mixture to flow towards said injection system, operating said engine by combusting said mixture to permit said cleaning fluid to clean said injection system as combustion is taking place; maintaining said closed container free from connection with said fuel pump and said fuel tank so that only said mixture flowing directly from said closed container will pass into said injection system.
