ASNU at Work

 

 

 

 

 

After the ultrasonic cleaning of injector, the serviceable items are replaced. The injectors are refitted with new filter baskets, pintle protection caps, spacers and O-Ring seals.


Then the injectors are re-tested for leaks, spray pattern shape and atomization, fuel delivery volumes and correct electronic operation. When the operator is satisfied that the injectors are performing as a properly matched balanced set, they are ready to be returned to the engine.

Report Pad


All results, before and after, are recorded on the ASNU Service Report Pad.

Requirements

In all cases it is essential that the electronic injectors perform as a matched and balanced set. Injectors are tested and checked for the following requirements:

·        A balanced fuel delivery at all operating points

·        Correct fuel distribution (Required point of atomization can vary)

·        Effective fuel atomization (create very small even droplets of combustible fuel)

·        Reliable valve seat sealing - no leaks

·        Retain all its functional values throughout its minimum service

·        Once the injectors have been tested, the pintle protection caps, filter baskets, spacers and O-rings are removed using ASNU's purpose built tools. The injectors are then placed in ASNU's purpose built ultrasonic cleaning bath for cleaning.

·        ASNU's patented ultrasonic cleaning process and variable cycle program cleans the inside of the injector, the pintle valve head, pintle seat and pintle needle guides, all back to their original manufactured condition.
