  1. Finally, because high - speed power solenoid valve is one of the most important executive parts in the electronic control diesel engine and the performances of diesel engine are strongly related to the solenoid valve, the response performance of the solenoid valve is investigated. the response performance of the solenoid is influenced by many factors, such as driving voltage, electric driving unit etc. in order to have high excitation voltage and in low maintaining voltage, a high - low voltage electric driving unit is designed, and in order to make the solenoid valve close more rapidly, an active free - wheeling circuit and a bootstrapping circuit are designed in the electric driving unit, too. in the high - low electric driving unit, high voltage and low voltage are supplied by the dc - dc device and by the accumulator respectively
