2011 FORD KUGA fuel consumption

reprogrammed. However, if the engine hasn't been
run since the last programmed start, the fuel-fired
booster heater will not start up the second time so
as to prevent the battery from being discharged.
The length of time required to pre-heat the vehicle
is calculated in the control unit of the fuel-fired
booster heater and is based on two temperature
values:
• Ambient air temperature: this message is taken
from the GEM via the CAN bus.
• Coolant temperature: this is determined via an internal sensor in the fuel-fired booster heater.
The maximum heating time is 30 minutes at an
outside air temperature of -10 °C or lower. The
heating time decreases proportionally with
increasing ambient temperature until the ambient
temperature is between +15 °C and +20 °C. Then
the minimum heating time is 10 minutes. The
parking heater is deactivated at temperatures
above +20 °C.
The sequence for a programmed start of the
booster heater is as follows:
• Two minutes before the start of the maximum heating time the driver information
system/instrument cluster sends an activation
message to the fuel-fired booster heater via the
CAN bus.
• The fuel-fired booster heater calculates the required heating time and, if necessary, sends
a delay request on the CAN bus.
• At the calculated time, the fuel-fired booster heater starts up. The conditions for start-up are:
engine not running and amount of fuel in the
fuel tank is above 14% of maximum.
• When the coolant temperature reaches +30 °C, the control unit of the fuel-fired booster heater
sends a request to switch on the passenger
compartment blower.
• Eight minutes after the programmed switch-off time, the booster heater stops heating mode
and starts a run-on operation to clean the
system's spark plugs.
• Ten minutes after the switch-off time, the post-cleaning operation is complete. The
additional ten minutes run-on time provides
some leeway in case the driver is late arriving.
After a programmed start-up of the booster heater
it is switched off again after the heating time has
elapsed (or if the fuel level in the fuel tank drops
below 8%). The booster heater stops within 2 minutes of the engine starting. This leaves enough
time to check whether the switch-on conditions for
boost heat mode have been met, thus preventing
the booster heater from having to switch off and
switch back on again. The heater can be switched
off manually at any time from the menu.
Whilst the fuel-fired booster heater is in additional
heating mode and/or parking heating mode, the
instrument cluster receives a fuel consumption
signal; this is used to re-calculate the vehicle's
remaining range and fuel consumption data.
Emergency shutoff
In the event of an accident in which the airbags
are deployed, the control unit of the fuel-fired
booster heater receives a message on the CAN
bus from the restraints control module (RCM).
When this message is received, the booster heater
system switches off immediately.
The booster heater control module deactivates the
system and does not respond to further messages
on the CAN bus. The booster heater control module
needs to be activated with WDS.
Component Description
Electric Booster Heater
The electric booster heater consists of three
individual heating elements, which are incorporated
into a single housing. It is controlled by the generic
electronic module (GEM), taking into account the
following factors:

Engine – System Operation and Component Description
System Operation
The variable camshaft timing occurs
electro-hydraulically and individually for both
camshafts.
The camshaft adjusters work according to the vane
cell principle and have an adjustment range of 52°
crank angle on the intake side and 47° crank angle
on the exhaust side. On starting the engine and
during idling, both camshafts are mechanically
locked in their starting positions. The exhaust
camshaft is in the early position and the intake
camshaft is in the late position. The camshaftadjuster on the exhaust side has a torsion spring
which compensates the camshaft drive torque.
This ensures that the assembly can return to the
starting position under all operating conditions and
when the engine is turned off.
Internal exhaust gas recirculation can be realized
through continuous adjustment of the timings. This
results in better fuel consumption and more
favorable combustion temperatures which produce
less pollutants. This means that pollutant level IV
can be adhered to with a 3-way catalytic converter.
The variable timings also make it possible to
optimize performance with wide open throttle.
