Electronic control of the engine control unit

ENGINE PRE—HEATING ELEMENT CONTROL

Pre/post—heating is turned on even if just one of the water, air or fuel temperature sensors signals a temperature

≤ 5 °C.

PHASE RECOGNITION

The cylinder in which fuel must be injected is identified upon starting via the signals of the sensor on the camshaft and/or on the
crankshaft.

INJECTION CONTROL

The control unit, according to the information from the sensors, governs the pressure regulator and varies the injection modes.

INJECTION PRESSURE CLOSED CYCLE CONTROL

Depending on the engine load, determined by processing the signals from the various sensors, the control unit governs the
regulator to have the optimum pressure at all times.

PILOT AND MAIN INJECTION ADVANCE CONTROL

Depending on the signals from the various sensors, the control unit determines the optimal injection point according to internal
mapping.

PEAK SPEED LIMITATION

Appropriate engine speed thresholds are stored in the control unit according to the application. When the engine speed exceeds
these thresholds the control unit actuates suitable reductions in power by controlling the electro—injector energising time.

SMOKE CONTROL

With load requirements, depending on the signals received from both the engine speed sensor, air temperature and the pressure
sensors the control unit adjusts the air fuel ratio in order to avoid black smoke.

TROUBLESHOOTING
General information

This Troubleshooting guide has been written for first level
service engineers.

The initial part of this Section describes the procedure for
connection and diagnosis by means of equipment 99368550.

By jointly using the troubleshooting ”clues” and the
summarizing tables with the event and error codes, you will
get an exhaustive picture of the situation as well as the specific
instructions to remedy the main faults.

The connection of the two tools is different so that
they cannot be mixed up. The tags of tool
99368550 tool have DIAGNOSE written on them
and the ones for of tool 99368543 have LOCAL
CONTROL written on them.

Troubleshooting carried out with the 99368550 equipment
can be performed by using simulation tool ILC 99368543 with
which it is possible to pilot the power pack that is to be
monitored locally.

The description of the ILC simulator tool follow the diagnosis
procedure.
