AI Technical Summary

Problems solved by technology

[0004] Due to the limitation of the drive current and size of the actuator of the electronic governor, the traditional mechanical-hydraulic governor is more widely used in high-power diesel engines. The measurement and amplification of the speed of the mechanical-hydraulic governor are all through mechanical components. Therefore, there are inevitably defects such as inertial hysteresis and frictional resistance, and the control method is single, and a more complex control algorithm cannot be realized. The adjustment accuracy is not high, and generally cannot meet the high-precision speed regulation requirements.
