Development of a High-Speed Solenoid Valve Measuring Bench

As the actuator of the high-pressure common-rail injector, the high-speed solenoid plays an important role in the fuel injection system of the diesel engines. This study introduced the high-speed solenoid valvepsilas prosperity and developed a test bench which could measure the magnetic force and response time of the high-speed solenoid. Finally, we tested a BOSCH solenoid with a Chinese made solenoid using the test bench for the relationship between the magnetic force, applying current and air gap which between the armature and the solenoid. With the test result, we can conclude that this test bench was fit to measure the prosperity of high-speed solenoid.
