1. After being unpacked, each injector is cleaned
externally. All o-rings, pintle caps, and inlet screens
are removed at this time.
2. Next, each injector is etched with its own serial
number to assist in tracking its history and performance
through the cleaning and testing process.
3. Injectors then undergo an electrical resistance
4. Each injector is also subjected to a voltage drop
or current draw test as another means of determining if
the coil windings are in good condition.
5. Next, the injectors are given a pre-cleaning flow
test, leak check, and spray pattern examination.
6. All injectors are then placed in the ultrasonic
bath and allowed to clean for a period of time.
7. Each injector is then individually backflushed to
remove any contaminants remaining inside.
8. The injectors are then placed back on the flow test
machine and subjected to a battery of static and dynamic
flow tests at various simulated RPM’s and
pulsewidths. All test information is recorded and a copy
of this information is returned to the customer.
9. Finally, the injectors are removed from the
machine, fitted with new o-rings, pintle caps, and inlet
screens and carefully packaged for return shipping.
