Product Description
Products Description
Common rail injector is one of the most important fuel injection systems in modern diesel engines. Based on the common rail fuel supply system, it can precisely control the fuel injection amount and fuel injection time to improve the combustion efficiency and power performance of the engine and reduce exhaust emissions and noise The working principle of the common rail injector is to transport high pressure fuel through a common rail to the fuel injector, and the fuel is injected into the combustion chamber by the injector to achieve high pressure fuel injection.
The specific working process is as follows:
1. Fuel supply: The fuel pump
pumps the low-pressure fuel from the fuel tank and pushes it to the high-pressure fuel pump. The high pressure fuel pump further pressurizes the fuel and delivers the high pressure fuel to the common rail through a pressure regulating valve.
pumps the low-pressure fuel from the fuel tank and pushes it to the high-pressure fuel pump. The high pressure fuel pump further pressurizes the fuel and delivers the high pressure fuel to the common rail through a pressure regulating valve.
2. High pressure oil storage: The common rail is an oil storage pipeline that can store high pressure fuel. The pressure provided by the high pressure fuel pump stores the fuel in the common rail for use by the nozzle. The pressure in the common rail can reach hundreds to thousands of bars.
3. Control valve operation: The common rail system also includes a component called a control valve. The control valve is controlled by the ECU(electronic control unit), which can accurately control the injection amount and injection time of the fuel injection nozzle according to the working condition and demand of the engine.
4. Nozzle injection: The nozzle in the common rail system is controlled by the control valve, and the fuel is injected into the combustion chamber at high pressure according to the instructions of the ECU. By controlling the opening time of the valve and the design of the injection hole, different injection quantity and injection Angle can be realized to adapt to the combustion requirements under different working conditions.
1. High pressure control: The common rail system can provide high pressure fuel supply, so it can achieve more precise control of fuel injection volume and timing, thereby improving engine combustion efficiency and power performance. 2. Energy saving and emission reduction: The common rail system allows multiple fuel injection and each injection can be adjusted as needed to reduce fuel consumption and exhaust emissions. Moreover, precise fuel injection control can also reduce fuel waste during cold starts and restarts after stopping. 3. Noise reduction: The high pressure injection of the common rail system can achieve a smaller injection particle size and reduce the injection noise. At the same time, the stable injection pressure reduces the fuel gasification and unstable combustion. 4. Adaptable: The common rail system can adjust the injection parameters according to different working conditions and requirements, such as the injection amount, injection time and injection Angle, so as to adapt to different engine needs and operating environments.
