The exterior of the injectors are then cleaned to allow for a closer inspection of the overall condition of the injector.
The injectors are next mounted onto the flow test bench and are pressure tested up to 80psi depending upon the conditions the injectors will be operating under when installed in the vehicle. Any injector(s) that leak or drip during this test are noted on the data sheet and will be checked again for leakage after the cleaning process has been completed.
The next test is a visual test of the injectors while being flowed under pressure. The injector spray patterns are checked for uniformity. Any injector that has an abnormal pattern is recorded.
Next, multiple flow volume tests are performed. First, all of the injectors are flow tested in both a static (wide open) and a dynamic (pulsed) mode. These are “timed” tests and range from 15 to 30 seconds. The results are noted for comparison after the cleaning process. As you can see from this illustration, the injectors can have a wide range of flow volume. This shows that these injectors are in need of cleaning and the engine they came from would not have been running as smoothly or efficiently as it would have if all of the injectors were flowing the same volume.
The final step is individually bagging up the injectors ready for return shipment.
