| Fuel flow rate through an injector is affected by a number of different things. This page focuses on the fact that even with nicely matched sets down to 2ms (0.002 seconds) pulsewidths, there can still be significant differences in your typical operating range. | Fuel flow rate through an injector is affected by a number of different things.

| - | Most injector testing places will not typically test below 4ms or if they do, certainly not below 2ms. For the most part, that's usually fine. Testing from 4ms up to 16ms (with a total time of 20ms, for example) provides a pretty good idea of the general behavior of the injector. As the chart below illustrates, injectors are almost always very linear in this area. | + | Most injector testing places will not typically test below 4ms or if they do, certainly not below 2ms.
