Product type
Common rail fuel injectors are precision-engineered components used in modern diesel engines to deliver fuel into the combustion chamber. They operate under high pressure, allowing for precise control of fuel injection timing and quantity, which enhances engine efficiency and reduces emissions. Typically made from high-grade materials such as stainless steel and engineered plastics, these injectors are designed to withstand harsh operating conditions.
| Material | Stainless steel and engineered plastics |
| Operating pressure | Up to 2000 bar |
| Nozzle type | Multi-hole or single-hole |
| Fuel type | Diesel |
| Electrical connection | Solenoid or piezoelectric |
| Typical lifespan | 200,000 to 300,000 kilometers |
When selecting common rail fuel injectors, consider the specific engine model and manufacturer requirements. Key specifications include the injector's operating pressure, nozzle type, and compatibility with the fuel system. It's also important to specify the desired lifespan and any necessary certifications or standards that the injectors must meet. Quantities can vary based on the application, so be prepared to discuss your needs with suppliers.
