FUEL INJECTOR TEST DATA REPORT
Each Fuel Injector will be returned with a Test Data Report that will detail the testing results of the fuel injector cleaning service. The Test Data Report will include the following:
Fluid Temperature – The temperature of the test fluid during testing.
Test Machine Number – An ID number that allows the test machine to be identified.
Test Pressure – The injector test is performed at 43.5 psi which is the industry standard for fuel injector flow.
Resistance – The coil resistance at the room temperature of the shop.
Leak Test – Each fuel injector is tested for leaks at 10, 40 and 100 psi. This test is performed three times before cleaning and three times after cleaning to ensure that any leak is detected.
Spray Pattern – A visual check of the spray pattern is performed and recorded as good, fair or poor.
Static Flow – The fuel injector is subjected to wide open testing and the volume of the flow is measured.
Pulsed Flow – The fuel injector is subjected to pulsating flow (on/off) to simulate normal operation.
CC/Min – The CC/Min value is determined from the static flow data and indicates that flow rate of the fuel injector at a specific test pressure.
Static Variance – The Static Variance is the difference between the lowest and highest flowing fuel injectors during the Static Flow Test. Typically, a low number is desired and will usually be less than 5%. The Static Variance is recorded before and after the cleaning process.
Pulsed Variance – The Pulsed Variance is the difference between the lowest and highest flowing fuel injector during the Pulsed Flow test. Typically, a low number is desired and will usually be less than 5%. The Static Variance is recorded before and after the cleaning process.
