What is Injector’s Static Flow rate?
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.
