Diesel Injectors and Injection Systems

Our specialist test equipment enables us to thoroughly test common rail diesel injectors and systems, including low pressure and high pressure fuel pumps.

Mechanical diesel injectors can also be examined on our test rig, for leaks, opening pressures and spray patterns.

Injector Problems

On most rail diesel systems, many components need to be correctly programmed to the vehicle and we at Central Garage Carcroft are able to adjust all calibration settings to their correct settings.

If your diesel vehicle suffers from any of the following contact us and rest assured we at Central Garage Carcroft will pinpoint the fault correctly and fix or replace the necessary part at the most cost-effective rate.

Petrol Injector Testing, Cleaning & Calibration

Electronically-controlled fuel injectors are durable and precise metering systems capable of pulsing for millions of cycles.

The most common problem we at Central Garage Carcroft come across with injectors is that they accumulate a build up of wax, tar, and olefins inside the injector and on the pintle/seat area.

We Fix Injector Problems

these types of debris will restrict the flow of fuel through the injector. Injectors are made to such close tolerances that a 5-micron buildup ( a human hair measures 40 to 90 microns) will reduce the flow by up to 25 per cent.

We at Central Garage Carcroft operate the only cleaning method recognised to clean these precise devices without damaging components.

Ultrasonic waves break up the contaminates while the injector pulses. The debris is then carried out of the injector by a biodegradable chemical.


Properly cleaned and maintained fuel injectors offer:

  • Savings to the motorist with improved fuel consumption
  • Lowered repair bills
  • Prolonged oxygen sensor life
  • Prolonged life of the Catalytic Converted Exhaust System
  • Preserves the environment from exhaust pollution by reducing CO pollution by an average of 36 per cent
