Abstract
An apparatus for cleaning an electronic fuel injector having an inlet and an outlet wherein the fuel injector is supported in an ultrasonic bath of cleaning fluid such that at least the outlet tip of the fuel injector is immersed in the fluid while the bath is resonated with ultrasonic energy. The fuel injector is pulsed by an electrical signal, the combination of the ultrasonic resonance and pulsing action causing the fluid to flow through the fuel injector from the outlet tip to the inlet.
Claims2
In an apparatus for cleaning an electronic fuel injector having an inlet tip and an outlet tip, the apparatus being of the type including means for supporting the electronic fuel injector in an ultrasonic bath of cleaning fluid such that at least the outlet tip is immersed in the fluid, means for resonating the bath with ultrasonic energy, a controller comprising:
- means for generating an electrical signal for pulsing said injector when free of any connection to a source of pressurized fluid, at a rate which causes the cleaning fluid to flow in a direction from the bath, into the injector outlet tip, through said injector, and to of the injector inlet tip, as a result of the interaction of the ultrasonic resonance and said pulsing action of said injector, and
- means for coupling said signal to said fuel injector so as to pulse the same, and
- said apparatus being free of a fluid connection between the injector inlet and a source of pressurized fluid when said fuel injector is pulsed by said generating means.
