Gasoline direct injection requires high pressure testing to truly diagnose operation faults. Speed Perf6rmanc3 once again provides the only complete testing solution in the market today, with the Revolutionary GDU.4r, GDU.2r and GD1r Test benches.
Below is a description of the various tests we perform when flow testing your DI Injectors using our state of the art GD1R Flow Bench. We use two separate pieces of equipment. The GD1R Flow Test Machine is used to measure all the flow characteristics of your DI Injector and a seperate machine is used for ultrasonic cleaning. We will continusouly clean each and every injector until it passes ALL TESTS with the GD1R and the injector meets OEM specifications as it would if the injector was new.
GD1R Flow Bench Machine Specs:
Tested at operating pressure up to 200 bar
R2LC - The R2LC Test is performance to check the impedance of the injector and make sure it is within OEM Specification
CFL - The CFL test is performed to test the injector for any fuel leakage both internally and externally while under pressure with the injector OFF.
NLT - The nozzle leakage test is performed to check that the injector doesn't leak fuel out for the nozzle tip while under pressure and injector is OFF. This test is done to see if you have what is stereotypically called "a leaking injector"
iVM (FL, PL, EM, LL, PI) - The iVM test is performed under various conditions such as full load, part load, etc. and is used to verify that the injectors flow rate and charactersitcs are within OEM Tolerances under all known conditions.
RSP - This test measures the fuel injector nozzle's response time (how long it takes for the nozzle to open when an electrical charge is applied) and that it meets OEM Spec.
SPR - This test is performed to ensure the injector's spray pattern has no abnormalities and that the shape of the spray pattern is how it should be when new.
