Fuel Injection Pressure: Common rail injectors operate at extremely high pressures, typically ranging from 1,000 to 2,500 bar (14,500 to 36,000 psi).
The exact pressure rating can vary depending on the engine's design and requirements.
Flow Rate: The injector's flow rate, measured in cubic centimeters per minute (cc/min) or milligrams per stroke (mg/stroke), determines how much fuel it can deliver in a single injection cycle.
Nozzle Design: The injector nozzle design is critical for achieving efficient fuel atomization and combustion. Different nozzles are designed for specific engine applications.
Fuel Compatibility: Injectors are designed to work with different types of diesel fuel, including standard diesel, biodiesel blends, and more. Compatibility with the fuel type is essential for long-term performance.
Response Time: This specification indicates how quickly the injector can open and close in response to signals from the engine control unit. Faster response times can lead to more precise fuel delivery.
Solenoid Type: Common rail injectors can use different types of solenoids or actuators to control fuel injection.
The type of solenoid can impact injector performance.
Injector Compatibility: The injector should be compatible with the specific make and model of the diesel engine it's intended for. This ensures proper fit and performance.
Operating Voltage: The voltage required to actuate the injector's solenoid is an important specification, typically around 12V or 24V for automotive and industrial applications.
