Speed Governor - EFC 4914090 is an injection system component: it meters and atomises fuel, or builds the pressure that makes that metering possible.
Injectors clog before they break: black smoke, rough running, power loss and high consumption. On common-rail engines, running an injector with excess return flow contaminates the oil and shortens pump life.

Frequently asked questions
Can injectors be cleaned instead of replaced?
If the problem is dirt and not wear, ultrasonic cleaning on a test bench restores flow. If needle or seat are damaged, no cleaning will fix it.
Why does the engine smoke black after an injector change?
Wrong calibration or air in the line. Verify bench calibration and purge the circuit before blaming anything else.
