ASNU Fuel Injector Testing
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 car’s system for "combustion related" problems, especially if the problem is related to Engine Performance, Fuel Economy, Exhaust Pollution and Lambda or Catalyst failure.
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.
