Diesel Fuel Injector 2057401 for Scania DC09 DC13 DC16 Engine for Cummins Injector

Fuel injection pressure refers to the pressure of fuel inside the injector, which directly affects the injection amount and injection time of the injector, thereby affecting the power and fuel economy of the engine. Optimizing injection pressure can be achieved in several ways:

(1) Adjust the parameters of the fuel pressure regulator

By adjusting the parameters of the fuel pressure regulator, such as the spring force and the opening of the regulating valve, the control of the injection pressure can be realized.

(2) Adopt high-pressure common rail fuel injection technology

The high-pressure common rail injection technology can increase the injection pressure and achieve precise control of the injection pressure through the high-precision electronic control unit, thereby improving the fuel economy and performance stability of the engine.

(3) Direct injection technology is adopted

Direct injection technology enables fuel injection directly into the cylinder, which can achieve more precise injection control by increasing injection pressure and injection speed, thereby improving fuel economy and performance stability of the engine.

Optimization of injection time

Fuel injection time refers to the duration of fuel injection when the injector injects fuel, which directly affects the combustion process of fuel and the power and fuel economy of the engine. Optimizing injection times can be achieved in several ways:

(1) Adjust the shape of the injector and the number of nozzles

By adjusting the shape and number of injection holes, the angle of injection and the injection time can be controlled, so as to realize the control of the injection time.

(2) High-precision electronic control unit is adopted

The high-precision electronic control unit can control the injection time and amount of fuel injected into the injector more precisely, thereby improving the fuel economy and performance stability of the engine.

(3) Adopt advanced fuel injection technology

For example, high-pressure common rail fuel injection technology and direct injection technology can control the fuel injection time and injection amount more accurately, and improve the fuel economy and performance stability of the engine.
