Characteristics of fuel injector circuit

According to the inherent characteristics of the solenoid valve, the intensity or duration of the strong excitation current and the holding current are adjusted, which can reduce the power consumption and prolong the life of the solenoid valve while realizing the accurate control of the fuel flow. The static protection is realized by using the transient suppressor tube, and the high frequency filtering is realized by using the combination of inductor and capacitor, which can suppress the interference signals in the complex working environment of the engine. The high side switch drive circuit and the low side switch drive circuit control the fuel injector work, can ensure that the fuel injector only at the right time to open, to ensure that the engine is not damaged. The current of the power supply and the winding output are collected to ensure that the circuit can be effectively monitored. When the injection is opened with a relatively high voltage, when the maintenance of the normal working voltage while using a relatively low current, can ensure that the injector quickly open and close. The addition of a diode in the output end and loop of the fuel injector can ensure that the high voltage induction electromotive force is generated when the fuel injector is opened and closed to play a continuation clamp and protect the internal chip from being damaged.
