System Description
3 System Description
3.1 Utilization of the EMR 2
The purpose of the electronic engine governor (EMR 2) is the regulation of the speed of revolution of DEUTZ
Diesel engines of the model series 1012/1013/2012/2013/1015 for applications in agricultural and con-
struction machinery as well as in generating sets. It is designed for heavy duty also under difficult environ-
mental conditions and possesses the corresponding protection classes.
The governor fulfils all the functions of the mechanical governor (variable speed governing, torque limitati-
ons, LDA function) and makes further functions available.
3.2 System overview
Basically, the EMR 2 consists of the sensors, the control unit and the actuator.
Engine-side as well as vehicle-side or plant-side installation are connected by means of separate cable har-
nesses to the EMR control unit. The cabling on the plant side is carried out by the vehicle or plant manufac-
turer.
For arrangement on the engine and plant/vehicle side, see the following figure.
