Injector Body: The injector body is typically made of durable materials to withstand the high pressure and temperature conditions within the engine.
It houses various internal components and is designed for reliable long-term performance.
Solenoid: A solenoid controls the timing and duration of fuel injection. It opens and closes in response to signals from the engine control unit (ECU). This precise control ensures accurate fuel delivery.
Nozzle: The injector nozzle plays a crucial role in atomizing the fuel into fine droplets. This atomization facilitates efficient combustion within the engine cylinders, contributing to reduced emissions and better fuel economy.
High-Pressure Rail Connection: Common rail injectors are designed to connect to a high-pressure fuel rail, ensuring consistent fuel pressure and precise control over fuel delivery to each cylinder.
Working Principle: The Delphi 28466774 injector, like other common rail injectors, operates based on the common rail direct injection (CRDI) system.
Fuel is pressurized by a high-pressure fuel pump and stored in a common rail. The injector opens in response to signals from the ECU, delivering fuel at the precise moment and duration required for efficient combustion.
Benefits: Common rail diesel injectors offer several advantages, including enhanced fuel efficiency, reduced emissions, and smoother engine operation. The precise control over fuel delivery and fuel atomization result in cleaner and more environmentally friendly engine operation.
Durability and Reliability: These injectors are engineered to withstand the harsh conditions within an engine bay and resist wear and tear, ensuring a long service life. Quality control and testing processes are typically in place to ensure consistent performance.
