Diesel Injector Fuel Injector 095000-7060 Denso Injector for Ford Transit, Ford Transit Tourneo, Land Rover Defender

Shaft needle and throttle nozzle are mainly used in diesel engines with non-direct injection combustor, while hole nozzle is used in diesel engines with direct injection combustor.

The service life of the nozzle couple is related to the cleanliness of the fuel, and the fuel must be deposited 48h before it can be used. In recent years, direct injection combustor with good economy is the mainstream of large and medium-sized diesel engines. In order to improve the performance of diesel engine and reduce discharge, the injection system is developing towards increasing injection pressure, improving atomization and shortening injection time.

At present, the injection pressure of the diesel engine using direct injection technology is very high. Because of the characteristics of the injector nozzle structure, the cavitation phenomenon will occur when the fuel flows through. In recent years, a large number of studies have shown that the cavitation inside the nozzle can enhance the injection atomization, which has a significant impact on the performance of the diesel injector and the efficiency of the combustion process, and the spray atomization of fuel determines the working performance of the diesel engine and the generation of pollutants. Therefore, it is of great significance to study cavitation flow characteristics in diesel injector. In recent years, the study of cavitation flow characteristics inside the injector has been widely paid attention to. Some scholars have analyzed the influence of cavitation inside the nozzle on the atomization process and atomization characteristics, and carried out visualization research on cavitation phenomenon inside the transparent nozzle. However, due to the very high velocity and pressure of the fluid inside the injector nozzle, the very small orifice and the short injection duration, it is very difficult to observe cavitation flow phenomenon and study its generation mechanism by using experimental methods, especially under the real physical size model.
