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 is an Injector’s Static Flow rate?
ERIKC Answer: Manufacturers rate fuel injectors by the maximum amount of fuel that they can flow in a given amount of time at a given pressure. This measurement is known as Static Flow Rate and is normally taken at 100% duty cycle and a fuel pressure of 43.5 PSI.
Example: At 100% duty cycle a 55 pound (lb) injector at 43.5 PSI of fuel pressure will flow 55 pounds per hour.
Injector Flow Rates are expressed in pounds per hour (lb/hr) or cubic centimeter per minute (cc/min). Given the same pressure 1 lb/hr = 10.5 cc/min.
To convert lb/ hr to cc/min, multiply by 10.5
Sometimes injector flow rates are expressed in milliliter per minute (ml/min)
1 ml = 1 cc
Example: a 220 cc injector = 220 ml injector
