About the product

The primary functions of the fuel injector in excavators encompass the following critical aspects:

1. **Precise Control of Fuel Injection Volume**: The fuel injector atomizes liquid fuel into fine mist-like particles with diameters ranging from 20 to 100 μm via a precisely engineered multi-hole nozzle (with hole diameters typically between 0.1 and 0.2 mm). This ensures that the volume of fuel injected is accurately controlled during each cycle, thereby meeting the demands of various operational conditions.

2. **Timing Function**: Modern high-pressure common rail systems employ either solenoid valves (in electronic fuel injection systems) or mechanical control mechanisms (in traditional diesel engines) to activate the fuel injector at precise moments, such as during the intake stroke of gasoline engines or at the top dead center of compression in diesel engines. This ensures optimal timing for fuel injection into the cylinder, enhancing combustion efficiency.

3. **Atomization Function**: The fuel injector transforms liquid fuel into a fine mist, increasing its contact area with air. This process not only improves combustion efficiency but also reduces pollutant emissions, addressing the dual requirements of modern engines for economic viability and environmental sustainability.

4. **Enhancement of Combustion Efficiency**: Through precise regulation of both injection timing and volume, the fuel injector ensures an optimal fuel-to-air mixture, promoting complete combustion and stabilizing engine power output.

5. **Reduction of Pollutant Emissions**: By atomizing fuel and increasing its interaction with air, the injector enhances combustion efficiency, thereby reducing harmful emissions and fulfilling the environmental protection standards expected of contemporary engines.

6. **Improvement of Engine Performance**: The precise control and atomization capabilities of the fuel injector enable the engine to operate efficiently across a range of working conditions, thereby enhancing overall engine performance and reliability.
