This article was carefully studied the governors development at home and abroad and the status quo, found that the traditional mechanical-electronic governor, there are many shortcomings: the control of precision low, slow response, etc., without changing the fuel injection system and transmission system under the circumstances The traditional mechanical speed control system into the modern electronic speed control system is mainly directed against the governor electronic control circuit, control procedures and their implementation is designed to fundamentally solve the traditional mechanical governor of the many drawbacks For the realization of the traditional diesel engine lay the foundation for the excellent performance.
