The methods for improving the power performance of high-pressure common rail components in automobiles are as follows:
1. Optimize the high-pressure oil pump
      Increasing oil pump pressure: By improving the internal structure of the oil pump, such as using more efficient plungers and optimizing the drive mechanism, the output pressure of the oil pump can be increased. For example, increasing the pressure of the fuel pump from 1800 bar to 2000 bar can make the fuel atomize more thoroughly, burn more completely, and release more energy, thereby enhancing power.
      Correct control of oil pump speed: Utilize a superior electronic control system to adjust the oil pump speed correctly according to the real-time operating conditions of the engine. When the engine is running at high load, increase the speed of the fuel pump to increase the fuel supply; Reduce engine speed at low loads to avoid fuel waste, better match fuel supply with engine demand, and improve power performance and fuel economy.
2. Improve the common rail system
      Optimize the material and structure of the common rail tube: Use high-strength and highly corrosion-resistant materials to manufacture the common rail tube, reducing internal pressure loss. Simultaneously optimizing its shape and internal flow channels, such as adopting smooth inner wall design, reasonable pipe diameter and bending radius, reducing fuel flow resistance, enabling fuel to be distributed more quickly and evenly to each injector, improving injection efficiency and uniformity, and enhancing power.
      Increasing the volume of the common rail: Appropriately increasing the volume of the common rail can better store high-pressure fuel, stabilize fuel pressure, provide more stable fuel supply for injectors, ensure good fuel injection under different engine operating conditions, and improve the stability and sustainability of power output.
3. Upgrade the fuel injector
      Improve the quality of fuel injector spray: adopt more precise processing technology and excellent nozzle design, such as increasing the number of injection holes, reducing the diameter of injection holes, optimizing the angle of injection holes, etc., so that the fuel injection is more refined and uniform, fully mixed with air, improving combustion efficiency, and improving power.
      Shortening the response time of fuel injectors: By using high-performance solenoid valves and drive circuits, the time delay from receiving signals to starting fuel injection, as well as the closing response time at the end of fuel injection, can be reduced to achieve more accurate fuel injection control, allowing fuel to be injected into the combustion chamber at a better time and improving the engine's power performance.
4. Adjust the electronic control system
      Optimize sensor accuracy: By using higher precision pressure sensors, temperature sensors, speed sensors, etc., various operating parameters of the engine can be monitored in real time more accurately, providing correct data support for the electronic control unit (ECU), enabling the ECU to make more accurate control decisions, optimize the working status of the high-pressure common rail system, and improve power.
      Improve ECU control strategy: By upgrading the software program of the ECU, optimize the fuel injection strategy, such as adjusting the fuel injection advance angle, fuel injection quantity, fuel injection frequency and other parameters in real time according to engine load and speed. Increase fuel injection quantity and pressure at low engine speeds to enhance torque; Adjust the fuel injection time and frequency at high speeds to ensure continuous power output.
