Idle speed
The idle speed setpoint is dependent on:
–the coolant temperature,
–the emission control programs,
–air conditioning requirements,
–the position of the gear lever,
–any power-assisted steering operation,
–the passenger compartment heating resistors,
–the oil temperature (engine protection),
–and lastly, the electric power balance (engine speed is increased by a maximum of 160 rpm if the battery voltage
remains below 12.7 V).
Ignition
Advance is calculated for each cylinder, and is limited between - 23˚ to + 72˚, and includes possible corrections due
to pinking.
Anti-pinking correction is the maximum advance value taken from the advance of one of the cylinders. If none of the
cylinders is pinking, this correction is zero.
Richness
For the catalytic converter to operate correctly, adjust around richness 1.
The richness regulation controlled by the upstream sensor which ensures a richness of around 1.
The upstream sensor supplies a voltage according to the image of the average engine richness: the voltage supplied
to the computer represents a Rich-Lean signal.
For the upstream sensor to be operational very rapidly, it is heated. The heating works only when the engine is
running. It is deactivated at speeds above 84 mph (140 km/h) or when the engine is under load.
The downstream sensor is also heated. The command does not activate immediately after starting the engine. It is
activated when the engine is running and has reached its operating temperature. The downstream heating sensor is
deactivated at speeds above 84 mph (140 km/h) or when the engine is under load.
Torque management
The torque structure is the system for managing engine torque. It is required for certain functions such as the
electronic stability program (ESP), automatic transmission (BVA) or sequential gearbox (BVR).
Each computer (ESP, sequential gearbox, automatic transmission) sends a request for torque via the multiplex
network to the injection computer. This intervenes between the torque requests received and the driver's requests
(made via the pedal or the cruise control/speed limiter function). The result of this intervention is the torque setpoint
to be applied. Using the torque setpoint, the structure calculates the throttle position setpoint, the ignition advance
and if the turbocharging function is present, the turbocharging solenoid valve setpoint.

Engine coolant temperature management
1. Conventional type thermostat
Engine cooling is performed by one or two fan assemblies (depending on the vehicle equipment). The injection
computer requests the UPC to actuate them via the multiplex network.
To ensure cooling, with the engine running, fan unit 1 is activated when the coolant temperature exceeds 99˚C and
stops when it drops below 96˚C.
Fan assembly 2 starts when the coolant temperature exceeds 102˚C and stops when it drops below 99˚C.
With the engine off, only fan assembly 1 may be activated to provide the anti-percolation function (if engine is
stopped when very hot). The anti-percolation function is active with the ignition off for a determined period. During
this time, fan assembly 1 is activated if the coolant temperature exceeds 100˚C and is deactivated when the
temperature drops below 95˚C.
If ET672: Engine coolant temperature management has a fault, then the temperature is regulated at 90˚C.
If a fault on the coolant temperature sensor circuit is detected, fan assembly 1 is activated and remains on all the
time.
If the engine coolant temperature exceeds the warning threshold of 118˚C, the injection computer directly
commands the coolant temperature warning light to come on or requests this action from the instrument panel
computer via the multiplex network, until the coolant temperature drops back below 115˚C.
As well as managing the engine, the injection computer centralises cooling requests for the air conditioning,
automatic transmission and sequential gearbox functions.
2. Controlled type thermostat
D4F 764 engines (with a camshaft dephaser solenoid valve) are fitted with a controlled coolant thermostat that
manages the engine at much higher coolant temperatures in order to reduce fuel consumption.
Description of operation
A conventional thermostat fitted with a heating resistor inside the wax core is used. The resistor is controlled by the
engine management computer by opening cycle ratio*.
In nominal operation, high coolant temperatures are managed in the engine in order to:
–reduce friction,
–reduce fuel consumption.
Nevertheless, defect operation mode is used to overcome faults linked to:
–reliability: at high engine speeds and high loads the engine temperature must be below 100˚C,
–performance: a high temperature increases chattering and reduces torque.
OCR*: Opening Cyclic Ratio.
