Fuel Injector Flow Testing in Florida

Fuel Injector Flow Testing and Diagnostic Equipment:

Manufacturer approved fuel injector cleaning, flow testing services and specialized computer controlled testing equipment allow Adriatic Boatworks to restore most dirty, clogged, gummed up or leaking fuel injectors to operate at the same level and standard as a new one.

Note: Reconditioned or remanufactured fuel injectors are used injectors that have been ultrasonically cleaned, flow tested and fitted with new O-rings, filter baskets and pintle caps.

Ohm Testing Fuel Injectors

Fuel injector cleaning and flow testing services begin with fuel injectors being Ohm tested for resistance. Those that fail the resistance test are not cleaned, deemed not repairable, and set aside.

Injectors are externally cleaned then inspected for external damage. Injectors with visual cracks and exposed coil winding are rejected and will not be serviced. Rejected or bad fuel injectors cannot be reused because they pose a fire hazard. Injectors are numbered and ready for the next step.

Note: We do not charge for any diagnostics performed on injectors that are not serviceable.

Fuel Injector Flow Testing:

Injectors are now installed in the Adriatic Boatworks computer controlled testing machine where they are evaluated for reluctance. If they fail the reluctance test they are deemed irreparable.

Fuel injectors are pressurized to +/- 45 psi /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 conducted to determine the amount of fuel delivered.

GDI or direct injectors are tested at 73.5 PSI (5 bars). Our test procedures for direct injectors are factory approved.

The Ultrasonic Fuel 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 approximately 25,000 – 30,000 times. Cleaning fluid enters the injector nozzle and in conjunction with the ultrasonic sound waves start to break loose the dirt inside of them. Once this process is completed, they are back flushed to remove all traces of dirt and contaminants.

Dynamic Injector Flow Testing:

Cleaned injectors are reinstalled in the injector flow bench where they are once again checked for leaks. After the leak test, the injectors are evaluated for atomization and distribution. Then, by means of dynamic flow testing, volume is assessed 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 the Adriatic Boatworks 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.
