The Development Trend of Common Rail Injector Technology in Denso Corporation
- Electronically controlled high-pressure common rail is one of the core technologies for diesel engines to achieve energy saving and emission reduction, and the fuel injector is the core technology for electronically controlled high-pressure common rail. According to the development history of fuel injectors for more than 30 years, improving injection pressure, fuel injection accuracy and improving spray effect are the three main technical development directions of fuel injectors. During the development of fuel injectors, the two technical routes represented by Denso and Bosch are the mainstream development directions of fuel injectors.
Denso Corporation launched its 120 MPa common rail injector used on large commercial vehicles in 1995, and then launched the 145 MPa common rail injector for passenger cars in 1999. These two injectors In terms of key technical features, they all belong to Denso's first-generation injectors. The second-generation injector launched in 2002 has been improved as follows: the diameter of the control piston has been reduced, and the original double-orifice structure of the first-generation injector has been changed to a single-orifice structure; the contact area of the armature has been increased ;Replacing the original electromagnet iron core with a composite soft magnetic integral iron core, canceling the fuel injector transition block; reducing the weight of the armature After the above improvements, the second generation injector is compared with the first generation injector. The response speed has been doubled, so the time interval between pre-injection and main injection has been shortened to 0.4 ms, making the injector capable of 5 injections; at the same time, due to the increase of injection pressure to 180 MPa and the control of pre-injection precision Within the range of (10.5) mm/str, the injector meets the Euro IV emission standard!
