Chapter 1: Principle and Design of Intelligent Control Injector Fuel Nozzles
1.1 Inadequacy of traditional oil injection control
In the traditional fuel injector system, the timing and volume of fuel injection are mainly performed based on pre-set fixed parameters. However, the operating conditions of the engine are complex and variable, and in actual operation, it is difficult to accurately match the needs of the engine in real time with the traditional oil injection method. For example, under rapid acceleration, hill climbing and other conditions, the fixed injection strategy can not provide enough fuel in time, resulting in the engine's power response is slow, unable to give full play to its performance. Moreover, under different ambient temperatures, altitudes and other conditions, the traditional injection system can not be flexibly adjusted, so that the fuel economy and emission performance are affected.

1.2 Innovation of intelligent control injector nozzle
The intelligent control injector nozzle introduces advanced sensor technology and intelligent algorithms. The engine's operating parameters are collected in real time through sensors installed in various key parts of the engine, such as the crankshaft position sensor, intake pressure sensor, oxygen sensor and so on. These parameters are transmitted to the on-board computer, which, after being analyzed by complex intelligent algorithms, is able to accurately calculate the optimal fuel injection volume and timing required by the engine under the current operating conditions. For example, when the engine suddenly accelerates, the sensor quickly captures the change in crankshaft speed, and the intelligent system immediately adjusts the opening time of the injector nozzles and the injection pressure to increase the amount of fuel injected, ensuring that the engine can respond quickly and provide sufficient power. At the same time, the system can also automatically make adjustments under different environmental conditions to ensure that the engine is always in the best working condition.

Chapter 2: Application and Advantages of New Materials on Fuel Injector Nozzles
2.1 Limitations of traditional injector nozzle materials
Traditional fuel injector nozzles are mostly made of metal materials, such as stainless steel. Although these materials have a certain degree of strength and corrosion resistance, there are still some problems in the harsh working environment of high temperature and high pressure. For example, the thermal conductivity of metal materials is high, in the injection process, the fuel is easy to be heated and vaporized, the formation of air pockets, affecting the stability and accuracy of fuel injection. And long-term in the high-pressure fuel flushing, metal nozzle nozzle holes are easy to wear, resulting in changes in the size of the nozzle holes, which in turn affects the quality of fuel injection and the performance of the engine.

2.2 Application of new materials and performance improvement
New injector nozzles began to use new materials such as ceramic matrix composite materials. Ceramic matrix composite materials have low thermal conductivity, can effectively reduce the gasification of fuel in the injection process, to ensure the stability of fuel injection. Its high hardness, wear-resistant features, so that the nozzle nozzle after long-term use can still maintain a good shape and dimensional accuracy, greatly extending the service life of the injector nozzle. At the same time, the ceramic matrix composite material also has good chemical stability, in the face of a variety of fuel additives and corrosive substances, showing stronger corrosion resistance. Experiments show that the use of ceramic matrix composite material injector nozzle, in the engine running [X] hours, the wear of the nozzle hole is only [X]% of the traditional metal nozzle, which effectively protects the long-term stable operation of the engine.

In summary, the injector nozzle based on intelligent control and new materials shows a lot of advantages, whether it is the precise injection brought by intelligent control or the stability given by new materials, which has injected new vitality into the development of engine technology, and it is expected to be widely used in the future automobile, ship and other power fields, and to promote the technological progress of the industry.
