New High Quality Diesel Nozzle G3S12 for Injection Nozzle Diesel Engine Parts

The main function of the injector nozzle is to atomize the fuel and precisely control the injection of the fuel to achieve efficient combustion of the engine, as follows:

Fuel atomization: Through the precise structure inside the injector nozzle, the high-pressure fuel is ejected from the nozzle at high speed to form fine oil droplets, which increases the contact area between the fuel and the air, is conducive to the full mixing of the fuel and the air, and achieves rapid and full combustion, improves the power output and fuel economy of the engine, and reduces pollutant emissions.

Precise control of injection:
Control of injection direction and angle: The number of nozzle holes, aperture size and distribution angle of the nozzle are carefully designed to make the fuel spray in a specific direction and angle, matching the shape of the engine combustion chamber and the airflow movement, ensuring that the fuel is evenly distributed in the combustion chamber, avoiding the concentration of fuel in local areas, and ensuring the stability and efficiency of combustion.

Control of injection timing: Under the precise control of the engine control unit (ECU), the nozzle can be opened and closed at the right time, so that the fuel is accurately injected into the combustion chamber at the end of the engine's compression stroke, synchronized with the movement of the piston and the pressure change in the cylinder, to achieve the best combustion phase and improve the performance of the engine.

Control the amount of fuel injection: The ECU controls the duration of the nozzle opening by adjusting the power-on time (pulse width) of the injector solenoid coil, thereby accurately controlling the amount of fuel injected each time, so that the engine can obtain appropriate fuel supply under different operating conditions (such as idling, acceleration, full load, etc.), maintain an accurate air-fuel ratio, and ensure stable operation of the engine.
