On the latest generation of Lambda controlled, Fuel Injected, Engine Management Systems, correct diagnosis of thecomplete 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 enginescorrect and efficient running, then the correct diagnostic programme should cover all the components related to thecomplete 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 whendiagnostically analysing any system for “combustion related” problems, especially if problem is related to EnginePerformance, Fuel Economy, Exhaust Pollution and Lambda or Catalyst failure.

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

Without “Injector Diagnostics”, it is impossible for garages to correctly, economically or efficiently, solve problems withFuel Injected engines. Servicing Injectors will also save time and money on Service and Repair bills, prolong the life ofInlet & Exhaust Valves, Piston Compression Rings, Lambda/Oxygen Sensors and the Catalytic Exhaust System.
