Chapter 1: Structural Design of New Fuel Injector Nozzles
1.1 Limitations of the structure of traditional fuel injector nozzle
The traditional fuel injector nozzle has exposed some problems in the process of long-term use. Its structure is relatively simple, and the shape and layout of the nozzle holes are more conventional, which makes it difficult to achieve accurate fuel atomization and uniform oil-air mixing during fuel injection . For example, in some engine conditions, it is easy to appear uneven fuel distribution, resulting in part of the combustion chamber fuel combustion is not sufficient, not only reduces the thermal efficiency of the engine, but also increases the emission of pollutants.

1.2 Innovative design of new fuel nozzle structure
In order to solve the problem of traditional oil nozzles, the new injector nozzle adopts a unique structural design. First of all, in terms of the shape of the nozzle, the traditional round nozzle is discarded, and a shaped nozzle design is adopted, such as oval, waist-shaped and so on. This design can change the angle and range of fuel injection, so that the fuel is more evenly distributed in the combustion chamber. Second, in terms of the layout of the nozzle holes, a combination of layered and staggered types is used. The layered layout can realize different levels of fuel injection according to different engine conditions to meet the needs of the engine under different loads; the staggered layout further enhances the atomization effect of the fuel and promotes the full mixing of oil and gas.

Chapter 2: Performance Advantages of the New Fuel Injector Nozzle
2.1 Improved Fuel Atomization Performance
The innovative structure of the new injector nozzle makes the fuel atomization performance significantly improved. Through the shaped nozzles and optimized nozzle layout, the fuel can be better broken into fine oil droplets during the injection process. Experimental data show that compared with the traditional nozzle, the average particle size of fuel droplets injected by the new nozzle is reduced by [X]%, which means that the fuel can be mixed with the air faster to form a more uniform combustible mixture, laying a foundation for the subsequent efficient combustion.

2.2 Engine performance improvement
The improvement of engine performance by the new injector nozzle is also very obvious. In terms of engine power output, due to the improvement of fuel atomization and mixing effect, the combustion process is more adequate and rapid, and the torque and power of the engine have been effectively improved. Test results on a particular engine showed that the use of the new nozzle increased the engine's maximum power by [X] kW and maximum torque by [X] N.m. At the same time, the engine's fuel economy was also improved, with a reduction in fuel consumption by [X] percent. In addition, due to the more complete combustion, the emission of harmful gases is also greatly reduced, of which the emission of nitrogen oxides (NOx) is reduced by [X]%, and the emission of particulate matter (PM) is reduced by [X]%, which is of great significance for environmental protection.

In summary, the innovation in structural design of the new injector nozzle brings significant performance advantages, whether it is the enhancement of fuel atomization performance, the improvement of engine performance and the enhancement of environmental protection benefits, which shows its great potential for application in the field of modern engines, and is expected to bring new breakthroughs in the development of the related industries.
