Fuel injection cleaning and testing system and apparatus

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

• a source of power;
• means for feeding either a cleaning liquid or fuel into said fuel supplying means of said engine, comprising
• an outlet conduit,
• means for storing a supply of said liquid or fuel,
• means for pumping said liquid or fuel from said storing means to said outlet conduit, and
• means for communicating said storing means with said pumping means;
• a control for said liquid or fuel feeding means, comprising
• means for operating said at least one electronically pulsed fuel injection valve disposed in operable association with said engine,
• switch means for determining the commencement or cessation of operation of said feeding means and said operating means, and
• means for operably associating said valve operating means and said feeding means with said source of power;
• means for operably associating said outlet conduit of said feeding means with said valve fuel supplying means to supply liquid or fuel to said at least one fuel injection valve from said storing means of said feeding means;
• means for measuring the flow through said at least one fuel injection valve during operation of the valve while the valve is operably secured to and associated with said engine, comprising
• flow meter means disposed at a location remote from said vehicle engine,
• first control valve means for permitting flow from said pumping means to said flow meter means, and
• second control valve means for permitting flow from said flow meter means to said at least one fuel injection valve;
• and
• a portable frame to which said feeding means, said control, and said measuring means are connected, and to which said flow meter means is mounted, to be transported to and from said engine.

An apparatus for 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 valve to feed fuel to said engine, and means for powering said controlling means, said apparatus comprising:

• means for feeding fuel into said fuel supplying means of said vehicle engine, comprising:
• an outlet conduit,
• a tank for storing a supply of said fuel,
• means for pumping said fuel from said storing tank to said outlet conduit, and
• means for communicating said storing tank with said pumping means;
• a control mechanism for said fuel feeding means, comprising
• means for operating said at least one electronically pulsed fuel injection valve disposed in operable association with said vehicle engine,
• first switch means for controlling the commencement or cessation of operation of said feeding means and said apparatus fuel injection valve operating means, and
• means for operably associating said valve operating means and said manual 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 an individual injector during operation of the testing apparatus while the injector is disposed on the engine, including second switch means for determining the commencement of flow measurement by said measuring means said measuring means being associated with and disassociated with said injector by means of the association or disassociation of said outlet conduit with said fuel supplying means;
• and
• a transporting device to which said fuel feeding means, said control mechanism and said flow measuring means are attached.

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

• a source of power;
• means for feeding fuel into said fuel supply means of said vehicle engine, comprising,
• an outlet conduit,
• means for storing a supply of said fuel,
• means for pumping said fuel from said storing means to said outlet conduit, and
• means for communicating said storing means with said pumping means;
• means for controlling said fuel feeding means, comprising
• means for operating said at least one electronically pulsed fuel injector disposed in operable association with said vehicle engine,
• switch means for determining the commencement or cessation of operation of said feeding means and said injector operating means, and
• means for operably associating said injector operating means and said switch means with said source of power;
• readily removable means for operably associating said outlet conduit of said feeding means with said injector fuel supplying means to supply fuel to said at least one fuel injector from said storing means of said feeding means;
• and
• means for measuring the flow through an individual fuel injector at a location remote from said injector during operation of the injector while the injector is operably associated with said engine, wherein said measuring means is associated and disassociated with said injector via the association and disassociation of said outlet conduit with said injector fuel supplying means.
