Solenoid Valve 096600-0033 for Denso Pump Diesel Pump Parts

Solenoid valve consists of main body, spool, bellows, shell, magnetic isolation sleeve, coil and so on. Its development mainly includes the selection of magnetic materials, core structure design, armature structure design, electrical parameter design, control valve design and other aspects. Most of the injector solenoid valves are two-position two-way form, the solenoid valve is closed when the power is not energized, and the electromagnetic suction is generated after the power is energized, which makes the armature lift up and the solenoid valve open, and the injector starts to spray oil. From the principle of operation, it is clear that the speed at which the solenoid valve opens and closes has a significant impact on the response performance of the injector.

Most of today's diesel engines use time-pressure controlled electronically controlled injection systems to cope with increasingly stringent emission regulations, where the "time" control mainly involves the flexible adjustment of parameters such as injection timing, injection volume, and injection rate of the injector. As the main component for realizing the above adjustment functions, the characteristics of the solenoid valve is one of the key influencing factors for the performance of the injector and even the entire injection system.As a result, solenoid valve optimization and performance enhancement has been an important part of the major companies' electronically controlled injector updates.

From the point of view of the injector layout, the major manufacturers of the new generation of common rail injector solenoid valve are given priority to the use of built-in, sunken program to shorten the hydraulic response time at the same time to ensure that the injector to match the installation size of the engine is basically unchanged. In addition, the trend of miniaturization synchronized with the built-in program not only reduces the cost, but also conducive to the improvement of product life.
