Development of a High-Speed Solenoid Valve. Experimental Results under Actual Loads.

We have developed a high-speed solenoid valve with a 1ms switching time to control a diesel engine electronically. We have already published our study concerning the circuit method for energizing the solenoid, and solenoid itself for fast switching. However, experiments of those studies are performed under simulated and light load conditions. In this paper we describe the test results of the high-speed solenoid valves under actual load conditions. Moreover, we used these solenoid valves as fuel-injection control tools for an electronically controlled diesel engine, and its performance is discussed.
