Injector Cleaning and Testing

Vesseys Classic and Performance Services have invested heavily into the tools needed to get the results they need for performance motoring. ASNU are the world leaders in injector testing and cleaning.

For any serious engine builder, it's essential to match the flow of your injectors and this can be done easily inhouse

On the latest generation of Lambda controlled, Fuel Injected, Engine Management Systems, correct diagnosis of the complete system is no longer an option, it's a requirement.

As these systems are "Closed Loop" a design where all the components in the system contribute to the engines correct and efficient running, then the correct diagnostic programme should cover all the components related to the complete Engine Management System, not just some of them.

The Fuel Injectors and their individual performance are now one of the major components to be considered when diagnostically analysing any system for "combustion related" problems, especially if problem is related to Engine Performance, Fuel Economy, Exhaust Pollution and Lambda or Catalyst failure.

Injector Diagnostics

Injector cleaning

ASNU have created a concept called "Injector Diagnostics", a Testing & Servicing programme where the injectors Fuel Distribution, Fuel Droplet Formation, Fuel Atomisation and Fuel Delivery, are all visually and physically checked and tested as an starting point, rather than a last resort. The injectors are then Ultrasonically cleaned and the rubber sealing rings, plastic protection caps and filter baskets are replaced, before re-testing, ensuring all the injectors are performing as a matched, balanced set.

Without "Injector Diagnostics", it is impossible for garages to correctly, economically or efficiently, solve problems with Fuel Injected engines. Servicing Injectors will also save time and money on Service and Repair bills, prolong the life of Inlet & Exhaust Valves, Piston Compression Rings, Lambda/Oxygen Sensors and the Catalytic Exhaust System. ASNU is approved World Wide by Robert Bosch GmbH.

Diagnosing injector performance

  • Before and after testing
  • Adjustable pressure
  • ASNU patented ultra-sonic cleaning process
  • Fuel SPRAY Management - spray pattern shapes and fuel atomisation are easily inspected in the ASNU display window.
  • Fuel delivery Volumes - the precise quantity of fuel delivered can be measured and compared for up to 6 top feed injectors or 6 side feed injectors at one time
  • Electronic operation - ASNU examines the injectors performance during a 10 programe option milliseconds and RPM simulation programme
