1. An apparatus for cleaning and testing the fuel injection valve system of a vehicle engine, said valve system including at least one electronically pulsed fuel injection valve operably secured to and associated with said engine, means for supplying fuel to said at least one valve, means for controlling said at least one electronically pulsed valve to feed fuel to said engine, and means for powering said controlling means, said apparatus comprising:

  • means for feeding a liquid into said fuel supplying means of said vehicle engine, comprising;

    an outlet conduit,means for storing a supply of said liquid,means separate from said fuel supplying means for pumping said liquid from said storing means to said outlet conduit, andmeans for communicating said storing means with said pumping means;

    means for controlling said liquid feeding means, comprising;

    means for operating said at least one electronically pulsed fuel injection valve disposed in operable association with said vehicle engine,switch means for determining the commencement or cessation of operation of said feeding means, andmeans for operably associating said valve operating means and said switch means with said powering means;

    means for operably associating said outlet conduit of said feeding means with said valve fuel supplying means and disabling said valve fuel supplying means to permit said feeding means to be the source of the fuel supply for said at least one fuel injection valve;

    means for measuring the flow through one fuel injection valve at a remote location during operation of the injection valve while the injection valve is operably secured to and associated with said engine, said measuring means being integrated with said fuel supplying means;

    a device for transporting said control, said communicating means, said pumping means, said storage tank, said outlet conduit and said measuring means to and from operable association with said engine; and

    valve means disposed on said transporting device for actuating said measuring means when said valve means is disposed in a first position and for bypassing said measuring means when said valve means is disposed in a second position, said measuring means being readily removable from operable association with said valve system by operably disassociating said outlet conduit operably associating means from said feeding means.
