In addition to the above methods, the injection pressure of the injector can be optimized by optimizing the injection pressure control algorithm and considering the engine operating conditions, thereby improving the engine performance, as follows:

Optimize the injection pressure control algorithm
Adopt advanced control strategies: such as model predictive control (MPC), adaptive control, etc. Model predictive control can optimize the injection pressure and other control parameters in advance according to the dynamic model of the engine and the prediction of future working conditions to achieve the best performance output. Adaptive control can automatically adjust the injection pressure control parameters according to the feedback information during the actual operation of the engine to adapt to the changes in engine characteristics, such as engine aging, different fuel quality and other factors.

Improve control accuracy and response speed: Optimize the hardware and software design of the electronic control unit (ECU) to improve the control accuracy and response speed of the injection pressure. For example, use higher-precision sensors to measure engine operating parameters, such as intake flow, cylinder pressure, etc., so that the ECU can more accurately calculate the required injection pressure. At the same time, optimize the signal processing algorithm and control command output speed of the ECU so that the injector can quickly respond to changes in injection pressure, ensuring that the appropriate injection pressure can be provided in time under different working conditions to optimize the combustion process.

Consider the engine operating conditions
Cold start condition: During cold start, the engine temperature is low, the fuel viscosity is high, and the atomization effect is poor. At this time, the injection pressure needs to be appropriately increased to improve the atomization and evaporation performance of the fuel, promote the formation of the mixture, and enable the engine to start quickly and run stably. At the same time, the adjustment of the injection timing can be combined, such as advancing the injection time, so that the fuel has more time to evaporate and mix in the cylinder, improve the cold start performance, and reduce emissions and fuel consumption during cold start.

High altitude conditions: At high altitudes, the atmospheric pressure is low and the air is thin. The engine intake volume is reduced. In order to ensure the performance and combustion efficiency of the engine, the injection pressure needs to be adjusted accordingly according to the altitude. Generally speaking, as the altitude increases, the injection pressure should be appropriately reduced to avoid incomplete fuel combustion due to insufficient air. At the same time, combined with control strategies such as adjusting the air-fuel ratio, the engine can maintain good performance and emission levels at high altitudes.
