ENGINE TORQUE CONTROL
System DescriptionINFOID:0000000001162540
The torque structure is the system which translates the driver's request into a torque supplied by the engine. It
is required for certain functions such as the electronic stability program (ESP), the automatic gearbox or the
sequentialgearbox if fitted).
Each inter-system (ESP, automatic gearbox, sequential gearbox) sends the ECM a torque request viathe CAN
communication. The computer arbitrates between the inter-system torque requests and the driver's request
(comprised of the accelerator pedal or the cruise control/speed limiter function). The result of the arbitration
gives thetorque setpoint.
From this torque setpoint, the computer determines the quantity of fuel to be injected (injection duration and
numberof injections) and the amount of air required (turbocharging pressure and EGR rate) so that the engine
is able toprovide the torque required in the best possible conditions (in terms of smooth running performance,
pollutantemissions, etc.).

GLOW CONTROL
GLOW CONTROL
System DescriptionINFOID:0000000001162542
Glow control involves controlling the glow plugs and the glow plugs "on" indicator light on the instrument panel
(via the can communication). The glow plugs are activated by a relay box and the power is provided by the
battery.
After the ignition is switched on. Preheating is activated for a period of time. The indicator light comes on for
the activation period which is dependent on the battery voltage, barometric pressure and engine coolant tem-
perature. When the engine coolant temperature is below a certain threshold, a postheating function enables
combustion stability, and thereby engine operation, to be improved (reduction in unburnt fuel and pollutant
emissions).
