Denso fuel injector

As mentioned above, Denso has installed a pressure sensor in the fuel inlet section of the fuel injector for some high-end models to directly measure the pressure fluctuation of the fuel injector. The actual fuel injection quantity is compared with the calibrated fuel injection quantity map, the relevant parameters are corrected, and the real-time compensation of the injector is realized through several cycles of correction. Since the system realizes real-time detection and compensation, it can significantly improve the injection accuracy of the injector, not only can compensate the error between individual injectors and batches, but also can compensate for the amount of oil caused by wear and tear after long-term work Changes, so that the injector can achieve accurate fuel injection throughout its life cycle. Although Denso has launched its fourth-generation common rail system on the market, the maximum working pressure of the fourth-generation products currently on the market is only 250 MPa, and its 270~300 MPa products are still in the research and development stage and have not been put into the market. According to relevant literature, Denso's next-generation injectors (G4.5S, G4P) will have three important features.
The first feature: to achieve a high degree of rectangularity of the main spray. Denso intends to improve the orifice plate structure mentioned in the first point, increase the flow rate of the oil outlet orifice and improve the electromagnet material, so that the main spray shape of its next-generation injector is closer to a rectangle, so as to realize the fuel injection. a high degree of liberalization.
