Fuel pump FORD KUGA 2011 1.G Owner's Manual

whereby the broadband HO2S emits a clear,
constant signal.
The broadband HO2S consists of a Nernst
concentration cell and an oxygen pump cell, which
transports the oxygen ions.

Between the oxygen pump cell and the Nernst
measuring electrode, there is a diffusion gap which
acts as the measuring area and is connected to
the exhaust gas. The Nernst concentration cell is
connected via a duct with the ambient reference
air and the measuring area. It detects the mixture
composition in the measuring area. A concentration
of lambda = 1 is set in the measuring area using
the oxygen ion flow. This is done by applying a
reference voltage which results in a pump current.
When the exhaust gas is lean, the oxygen pump
cell is actuated in such a way that oxygen ions are
pumped out of the measuring area. This is detected
by the regulating switch, so that the flow can move
(positive direction).
If the exhaust gas is rich, then the current direction
is reversed, i.e. the cell pumps oxygen ions into
the measuring area. The regulating switch detects
this, so the flow is reversed (negative direction).

The pump current represents a direct measurement
of the mixture composition. With lambda 1 (14.7
kg air/1 kg fuel), the pump current is 0 mA. The
relatively small measured current is converted into
a voltage signal in the PCM using an evaluation
circuit. The heating of the broadband HO2S is
supplied with a reference voltage of 11 to 14V. The
operating temperature of the broadband HO2S is
650 - 900 °C.
The characteristic curve of the broadband HO2S
is constant (linear), without a lambda jump.
VCT (variable camshaft timing) solenoids
The camshaft adjustment solenoids are multi-way
solenoid valves that are actuated with a PWM
signal, thereby allowing the valve plungers to be
steplessly adjusted.

Installation position
The PWM solenoid valve for the TCC (SLU) is
located in the valve body on the front of the
transaxle.

The valve actuates the torque converter clutch as
well as the reverse gear brake (B3) and 2nd - 5th
gear brake (B2). The PWM control achieves
smooth engagement of the gears. The two brakes
are actuated in 1st and 2nd gear to guarantee
engine braking.
The valve also actuates the torque converter in
such a way that is works in three positions: 'open',
'controlled looping (slip lock-up mode)', and 'locked
(full lock-up mode)'. The hydraulic function of the
valve is linear.
In lockup mode the TCC is closed. The impeller
and the turbine of the torque converter are friction
locked. The engine torque acts directly on the
transmission input shaft. Fuel consumption is
reduced due to a reduction in the torque converter
pump losses.
In slip lock-up mode, slip in the TCC is permitted
in order to improve driving comfort. The hydraulic
pressure acting on the TCM varies in accordance
with the duty signal of the actuation signal
generated by the PWM for the TCC solenoid valve
for the TCC (SLU). The temperature of the
transmission fluid increases in slip mode.

The fluid pump operates on the principle of a
G-rotor fluid pump.
The fluid pump draws transmission fluid from the
fluid pan, builds up fluid pressure and then supplies
it to the valve body.
The fluid pump is driven by the crankshaft via the
torque converter housing.

Stator with roller-type one-way clutch
5 The torque converter transmits the output torque
hydraulically from the engine to the transaxle input
shaft.
The stator increases the torque up to the clutch
take-up point. At the clutch take-up point, the speed
difference between impeller and turbine is
approximately 90 %.
In order to improve the efficiency, the torque
converter features a hydraulically-activated TCC.
When the TCC is engaged, the torque is
transmitted directly from the crankshaft via the
torque converter housing to the transaxle input
shaft.
Installation position
The TCC is an integral component of the torque
converter.
Function
The TCM controls the PWM via the TCC solenoid
valve for the TCC (SLU). Based on the signals for
engine speed and accelerator pedal position as
well as vehicle speed, driving comfort is improved
by linear actuation of the TCC.
