ESG2002 SERIES ELECTRONIC GOVERNOR INSTRUCTION

1 The Principle Of The Electronic Governor System Electronic governor, with its simple structure, high reliability, convenient operation, easy function extension and high cost performance, applies to all kinds of diesel generating sets, vehicles and marine diesel engines. Its normal type is all-electronic single pulse speed and close loop position structure, provided with functions of non-corresponding or corresponding control, speed and rated speed during running maximum fuel supply control, emergency stop and etc. It is also capable of adding other control functions according to the customer’s particular requirements.
