Product Knowledge: Common Rail Injector

The Common Rail Injector (CRI) is the centerpiece of modern diesel engine fuel systems. Unlike older, mechanical systems, the Common Rail system stores fuel at extremely high pressure (up to 2,000 bar or more) in a common rail that feeds all injectors. The injector, like the Caterpillar 320-0680, is electronically controlled (via a solenoid or piezoelectric actuator) to precisely regulate the timing, duration, and quantity of fuel sprayed into the cylinder. This precision is what allows engines like the C4.4 to achieve lower emissions, improved fuel economy, and higher power output.
