DEUTZ Engine and Machine Control

Home / Technical Articles / Details ...

Engines with DCR® communicate with the machine via a CAN-Bus protocol. This enables functions such as “drive by wire” and the full integration of the engine control in the electronically controlled hydrostatic powertrains of vehicles or machines. Another advantage of these fully automatic, electronic controllers is the integrated engine diagnosis and safety system. If the engine controller registers an unusual state, such as engine overheating, during operation, the engine performance is reduced to emergency mode and is necessary down to shutdown. This avoids cost-intensive repairs and increase the operational reliability/operating availability of the work machines.

We will use our present mechanical control systems for engines in the lower performance range as far as possible. These systems feature the simplest mechanical centrifugal force controllers and closed, torque-controlling centrifugal force controllers which are partly common in engines up to 7 litre capacity nowadays.

Cases exist in which a machine benefits from the uncomplicated nature of a mechanical injection system but still requires the control complexity of an electronic engine controller. We satisfy this need by using the DEUTZ EMR® control system. EMR® is a programmable speed controller which imitates the functions of fully automatic electronic controllers but without the ability to change the ignition time. Functions such as “drive by wire”, continuous speed control, multiple saved torque curves, torque control and engine safety control are also provided by the EMR® control system.
