(7) Knocking Control
A. Resetting the pilot injection
The knocking control is used to reset the pilot injection flow in closed loop for each injector. This
method allows the correction of any injector deviations over a period of time. The principle of use of the
knocking control is based on the detection of the combustion noises.
The sensor is positioned in such a way as to receive the maximum signal for all the cylinders. The raw
signals from the knock sensor are processed to obtain a variable which quantifies the intensity of the
combustion. This variable, known as the ratio, consists of the ratio between the intensity of the
background noise and the combustion noise.
A first window is used to establish the background noise level of the knocking control signal for
each cylinder. This window must therefore be positioned at a moment when there cannot be any
combustion.
The second window is used to measure the intensity of the pilot combustion. Its position is such
that only the combustion noises produced by the pilot injection are measured . It is therefore
placed just before the main injection. 1.

The knock sensor does not allow any evaluation of the quantity injected. However, the pulse value will
be measured when the injector starts injection and this pulse value is called the MDP (Minimum Drive
Pulse). On the basis of this information, it is possible to efficiently correct the pilot flows. The pilot
injection resetting principle therefore consists of determining the MDP, in other words the pulse
corresponding to the start of the increase in value of the ratio (increase of vibration due to fuel
combustion).

This is done periodically under certain operating conditions. When the resetting is finished, the new
minimum pulse value replaces the value obtained during the previous resetting. The first MDP value is
provided by the C3I. Each resetting then allows the closed loop of the MDP to be updated according to
the deviation of the injector.
B. Detection of leaks in the cylinders
The accelerometer is also used to detect any injector which may have stuck open. The detection
principle is based on monitoring the ratio. If there is a leak in the cylinder, the accumulated fuel self-
ignites as soon as the temperature and pressure conditions are favorable (high engine speed, high
load and small leak).
This combustion is set off at about 20 degrees before TDC and before main injection.
The ratio therefore increases considerably in the detection window. It is this increase which allows the
leaks to be detected. The threshold beyond which a fault is signaled is a percentage of the maximum
possible value of the ratio.
Because of the severity of the recovery process (engine shut-down), the etection must be extremely
robust.
An increase in the ratio can be the consequence of various causes:
Pilot injection too much
Main combustion offset
Fuel leak in the cylinder -
-
-
If the ratio becomes too high, the strategy initially restricts the pilot injection flow and retards the main
injection. If the ratio remains high despite these interventions, this shows that a real leak is present, a
fault is signaled and the engine is shut down.
C. Detection of an accelerometer fault
This strategy permits the detection of a fault in the sensor or in the wiring loom connecting the sensor
to the ECU.
It is based on detection of the combustion. When the engine is idling, the detection window is set too
low for the combustion caused by the main injection. If the ratio increases, this shows that the knock
sensor is working properly, but otherwise a fault is signaled to indicate a sensor failure. The recovery
modes associated with this fault consist of inhibition of the pilot injection and discharge through the
injectors.

2. CAUTIONS WHEN WORKING
Wear clean work clothes and gloves.
Any unauthorized modification or operational test is not allowed since the sunroof motor and control
unit are preset at the factory.
Pay attention not to drop the sunroof assembly when removing it and do not keep it right up. -
-
-
Even though the sunroof can be operated when the engine is not running, operating the sunroof
repeatedly with the engine turned off will run down the battery. Operate the sunroof while the engine
is running.
When the sunroof operation is completed, release the switch. Keeping pressing the switch can result
in malfunction.
Especially in winter, never operate the sunroof if operation areas are iced. Wait until melted.
To prevent a theft, make sure that the sunroof is completely closed when leaving the vehicle. In
addition, rain or snow can get into the vehicle through the open sunroof.
When the sunroof is fully open, wind buffeting symptom can be worse. In this case, try to adjust the
sunroof position manually or open the sunroof until the wind buffeting is disappeared
Parts of the body can be trapped in the sunroof and can be struck by passing objects. Do not stick
hands, head or anything else out of the openings.
Remove any dirt and foreign material stuck on the edge of the sunroof glass periodically. -
