Asnu

Asnu manufacture servicing and testing equipment for electronic petrol injectors.  This test equipment allows us to perform accurate testing of flow rates and spray patterns under control conditions.  This equipment also allows us to ultrasonically clean the internal components of the injectors to remove rust, carbon and lacquer deposit from the injector, all of which can cause flow and spray pattern problems.

Some of the symptoms listed below could indicate that your injectors are faulty and not working to their full potential.

Starting Problems...                          Difficult to start, hot or cold or will not start at all.

Poor Fuel Economy...                      Vehicle has good performance, but excessive fuel consumption.

Excessive Exhaust Emissions...  MOT failure on exhaust emissions, no adjustment
                                                               available. Lambda or Catalyst exhaust failure.

Idling Problems...                              Erratic and un-even idling, surging, misfiring, ‘pinking’and
                                                               adjustment fails to resolve problem.

Lacking Performance...                   Lack of power, flat spots, poor throttle response, car not
                                                               performing like it should or use to.

Poor Driveability...                           The car hesitates, ‘pinks’ under load, erratic performance and
                                                              throttle response.

ECU Error Warning Codes...         Error code shows fault with Lambda or Air/Fuel mixture and 
                                                              checks show no fault.

There are three main faults that can cause you to suffer from the above problems.  These are indicated below along with the knock on effects that these faults can have on you vehicle.

Leaking Injector Valves will cause:  Wetting of the manifold walls, that can cause Starting problems, Bore Wash, Lacquering of the Lambda Sensor & Clogging or Failure of the Catalyst Exhaust .

Poor Fuel Distribution & Atomisation will cause:  Excessive Exhaust Emissions, Poor Fuel Economy, Idling Problems, Lack of Power, Poor Driveability, Gumming or Sticking of the Inlet Valves, Lacquering of the Lambda Sensor & Clogging or Failure of the Catalyst Exhaust.

Un-even Fuel Delivery Rates will result in:  Incorrect Exhaust Emissions, Lambda Sensor & Catalyst Exhaust Problems, Idling Problems, Lack of Power, Poor Driveability.

This illustration shows six injectors all with varying spray patterns and a explanation of their condition.
