An apparatus is provided for cleaning residue fuel varnish and carbon from the fuel nozzles and guide vanes of a jet engine. The apparatus is constructed to dispense a detergent and water solution under sufficient pressure through the nozzles themselves to scrub residue fuel varnish and carbon from the fuel nozzles and from the guide vanes of a jet engine of an aircraft without the need for removing the same from the engine. In its operation, the apparatus serves to wet down the surfaces of the nozzles and guide vanes with a detergent solution for a period of time (i.e. about twenty minutes), then to scour the surfaces with a pulsating detergent spray, and finally to purge the surfaces with a pressurized air stream. The apparatus is conveniently mounted on a vehicle, so that it can be moved to the work site.

Apparatus for cleaning residue fuel varnish and carbon from the fuel nozzles and guide vanes of a jet engine including: an inlet for receiving compressed air; an outlet configured to be coupled into the fuel system of a jet engine so that fluid emitted by the outlet may be discharged through the fuel nozzles of the jet engine to perform a cleaning function; air receiver means; first compressed air operated pump means coupled to the inlet for introducing compressed air into the air receiver means so as to achieve a predetermined air pressure in the air receiver means; a first liquid accumulator means coupled to the air receiver means; a reservoir for a cleaning solution; a second compressed air operated pump means coupled to the inlet and to the reservoir and to the first liquid accumulator means for introducing cleaning solution from the reservoir into the first liquid accumulator means against the pressure of compressed air from the air receiver means; first conduit means coupling the first liquid accumulator to the outlet; a first valve included in said first conduit means; and control means coupled to said first valve for controlling the flow of the cleaning solution through said first conduit means from the first liquid accumulator means to the outlet.
