FAQ: How Does a fuel injector work?

ERIKC Answer: Fuel under pressure is sprayed in a very fine mist from the tip of the injector. To achieve this, a current must flow through the injector. Contrary to popular belief, this is NOT done by sending power to the injector. Fuel injectors are normally fed power whenever the ignition key is on, but the circuit is not completed and therefore the injector is still closed. The computer controls the ground side, of the circuit. When the computer provides the ERIKC injector with a ground, the circuit is completed and current is allowed to flow through the injector. This energizes an electromagnetic coil inside the injector, which pulls a sealing mechanism such as a pintle, ball, or disc away from its seat. This makes it possible for fuel to flow through the injector and into the engine. When the computer removes the electrical ground to the injector, the electromagnetic coil becomes demagnetized and a spring forces the pintle, ball, or disc shut to cut off fuel flow.

FAQ: What does the term static means?

ERIKC Answer: If an ERIKC injector stays on all the time, 100% duty cycle, it is said to be static. Injectors should never go static because control of fuel delivery is lost and this can cause catastrophic engine failure. Static injectors, or 100% IDC is normally an indication that the injector is too small for the engine. Injector duty cycle should usually not exceed 80%. Once 80% IDC is reached a bigger injector should be installed.

In some instances low fuel pressure or a failing fuel pump can cause injectors to become static. On the other hand, there are some injectors that will go static if the fuel pressure is too high.
