WEIFU ECU56 ELECTRONIC GOVERNOR
Technoparc du Brégadan - 13260 Cassis / France –Tel. +33 488 688 500
1 Preface
This manual mainly introduced the working principle, composition, adjustment, operation, maintenance
and some simple fault elimination methods of the electronic speed control system.
It is applicable to the staff who have knowledge of the engines andelectronic speed control unitsand those
who do some daily installment, connecting wires, using and maintenance.
We suggest You shall put the manual in the workplace and strictly follow the methods provided here.
2 Warning
Speed sensor to the electronic control system shall not be shared with other systems, or they may cause
serious consequences.
You can't rely on the electronic speed control system to prevent engine overspeed, and overspeed
protection device installed independently, effectively in the engine system.
Before starting the engine should confirm the fuel injection pump rod in oil cut-off position, push and pull
the fuel rack should be flexible and no jam.
3 Working principle
The electronic governor is based on the working principle of the mechanical governor but electronic
governor is better than mechanical governor. The electronic governor permit to the diesel engine to have
a prominent steady state speed regulation and a good transient speed regulation performance that can
quickly and accurately respond to the change of the engine state.
This electronic governor is a full digital control of electronic governor, the system structure diagram as
shown in the following figure.
The electronic governor collects the throttle position and the engine speed, and then sends out the
instruction of tension bar’s position to control the supply of oil pump.
In the power generation mode, the throttle device becomes a switch to control idle speed to operating
speed. Governor control the working speed by PID controller to ensure that the steady speed and the
transient speed of engine meet requirements.
