FUEL INJECTOR REFURBISHING
Injector Cleaning Machine
FUEL INJECTOR FLOW TESTING
The injectors are now installed in our computer-controlled testing machine where they are tested for reluctance. If they fail the reluctance test they are deemed irreparable.
The fuel injectors are pressurized to +/- 45psi /3 bar and visually checked for pintle, ball, or disc seat leaks. Spray patterns are checked for atomization and distribution. Finally, a flow test is done to determine the amount of fuel delivered.
FAULTY FUEL INJECTORS
Faulty fuel injectors will cause check engine light to display. Faulty injectors that are gummed up, clogged, leaking, or dirty have the potential to cause expensive and catastrophic engine failure. Proper maintenance will help and cleaning should always be considerate as part of your maintenance plan especially on older engines.
CLEAN FUEL INJECTORS
Clean fuel injectors will:
Improve fuel economy
Reduce exhaust pollution
Increase engine performance
Reduce service and repair costs
Save you money
THE ULTRASONIC INJECTOR CLEANING PROCESS
Where applicable, components such as O-rings, filter baskets, and pintle caps are removed. The injectors are now ready for the ultrasonic injector cleaning process and placed in an ultrasonic bath containing a hot biodegradable environmentally friendly cleaning fluid.
The injectors are opened and closed at various speeds for approximately 25,000 – 30,000 times. Cleaning fluid ultrasonic sound waves start to break loose the dirt inside of them. Once this process is completed, they are backflushed to remove all traces of dirt and contaminants.
DYNAMIC INJECTOR FLOW TESTING
The cleaned injectors are now reinstalled in the injector flow bench where they are once again checked for leaks. After the leak test, the injectors are tested for atomization and distribution. Then by means of dynamic flow testing, volume is tested under a set fuel pressure and various rpm. Finally, a static flow test is performed. Flow testing results are compared to see if they match those in our database.
Once all the required tests are passed, new O-rings, filter baskets, and pintle caps are installed, (if and when available). The cleaning process is now complete and the reconditioned fuel injectors are lubricated and placed in a plastic bag. A comprehensive report is prepared for the owner and included.
Note: We don’t easily give up on leaking injectors or the ones that prove difficult to clean. In most instances, we will keep on trying until the injectors work the way they should. When we service fuel injectors and cannot restore them to function like new, we will not charge you for the extra time spent.
