Deutz Engine Control Units EMR4 Instruction Guide

With the launch of theDEUTZ Tier4engines (interim and final) the engine management system EMR4 with the control units EDC17CV52,CV54,CV56 (depending on the needed functionality) will be established.

 

AlI DEUTZ DCR engines(DEUTZ Common Rail System for TCD4.1,TCD6.1,TCD7.8,TCD12.0) are equipped with one EDC17controller, except the TCD16.0 with two controllers (master and slave).

 

The engine management system allows a precise control of the fuel injection depending on the engine operating parameters. It contains functions, which are necessary for achieving a high system security level and the required exhaust quality.

A detailed description of the control units can be found in the EMR4 System Description.

 

Functional description EMR4

The control unit EMR4 is compatible to the EMR3 with regards to the interface functions.

The following standard functions (depending on the availability in the ECU) are provided:

1 Ambient pressure-depending filling limit

2 Monitoring and engine protection functions: fuel filter, fuel pre-pressure, charge air temperature,

rail pressure,oil pressure, coolant temperature, speed

3 Engine start controlled by ECU ( activation starter and starter protection function as restart lock, etc.)

4 Engine stop by switch.

5 Activation control and monitoring of the exhaust aftertreatment (EAT) components (DPF and/or SCR)

 

In addition the following optional functions are provided:

1 Velocity control and limitation

2 Multiple State Switch1 (up to 4 fixed speeds selectable)

3 Extendable monitoring and engine protection functions:

coolant level, air filter differential pressure and monitoring of the EAT componets

4 Extended test functions

5 Override Function (delay of engine shutdown)

6 automatic engine shutdown (engine protection) or only shutdown request (for special applications)

 

System elements EMR4

The EMR 4 system consists of at least these elements:

1 Control unit (ECU)

2 Speed sensors for the crankshaft and the camshaft

3 Rail pressure sensor,rail pressure control valve(MPROP,PRV)

4 Temperature sensor (coolant)

5 Combined charge air pressure and charge air temperature sensor

6 Oil pressure sensor

7 Ambient pressure sensor (integrated in the control unit)

8 Speed setpoint transmitter, accelerator pedal

9 Signal light for warning,diagnostics,error message etc.

10 Diagnostic button

11 Engine wire harness and vehicle wire harness

12 Monitoring fuel pre-filter (water in fuel)

13 Controlling and monitoring of the EAT-system(Exhaust After Treatment)
