actuated) or opened (actuated). Each cylinder has
its own injector. The injection is accurately dosed
and takes place at a time determined by the PCM.
Injection takes place immediately in front of the
intake valves of the cylinder. The injectors are
actuated ground side via end-stages integrated
into the PCM and using the signal calculated by
the engine management system. Power is supplied
via the Powertrain Control Module relay in the BJB.
The injected fuel quantity depends on the opening
time, the fuel pressure and the diameter of the
nozzle holes.
The fuel metering is determined via open or
closed-loop control.
The open control loop differs from the closed
control loop in that the lambda control is
deactivated.
The PCM switches from closed to open-loop control
if the HO2S cools down to below 600°C or fails, as
well as when accelerating, coasting and at full load.
Regulation of injected fuel quantity via the PCM
involves:
• controlling the fuel pump,
• calculating the required quantity of fuel forengine starting,
• observance of the desired air/fuel ratio,
• calculating air mass,
• and calculating the fuel quantity for the different operating states and corresponding fuel
adjustment measures.
Open loop control
Open loop control is used primarily for fuel
injection, as long as the signals of the HO2S are
not involved in the calculation of the PCM.
The two most important reasons that make it
absolutely essential to run the engine without
lambda control (open-loop control) are the following
operating conditions:
• Cold engine (starting, warm-up phase)
• Full-load operation (WOT (wide open throttle))
Under these operating conditions the engine needs
a rich air/fuel mixture with lambda values below λ
= 1 in order to achieve optimum running or
optimum performance.
It is possible to keep this unregulated range very
small by using a broadband HO2S.
Closed-loop control
Closed loop control ensures strict control of
exhaust emissions in conjunction with the TWC (three-way catalytic converter) and economical fuel
consumption. With closed loop control, the signals
from the HO2S are analyzed by the PCM and the
engine always runs in the optimum range of λ = 1.
In addition to the normal HO2S, the signal from the
monitoring sensor for the catalytic converter is also
included in the control. The lambda control is
optimized on the basis of this data.
Certain factors such as wear, component
tolerances or more minor defects such as air leaks
in the intake system are compensated for by
lambda control. If the deviation occurs for a longer
period of time, this is recorded by the adaptive
(self-learning) function of lambda control. In this
instance, the entire map is shifted by the
corresponding amount, to enable control to
commence once again from the virtual baseline.
These adaptive settings are stored in the PCM and
are also used in open-loop control conditions.
If the adaptive value is too high or too low, an error
is stored in the fault memory of the PCM.
Oxygen sensor (HO2S) and catalyst monitor
sensor
A broadband HO2S is used as the HO2S. The
HO2S is located in front of the TWC. The catalyst
monitor sensor is located in the center of the TWC
so that it can detect any deterioration in the
cleaning performance of the TWC more quickly.
The HO2S measures the residual amount of
oxygen in the exhaust before the TWC.
The catalyst monitor sensor measures the amount
of oxygen in the exhaust gas after or in the TWC.
Both the HO2S and the catalyst monitor sensor
transmit these data to the PCM.
The broadband HO2S works at temperatures of
between 650°C and 900 °C. If the temperature
rises above 1000°C, the oxygen sensor will be
irreparably damaged.
To reach optimum operating temperature as quickly
as possible, an electrically-heated oxygen sensor
is installed. The heating also serves to maintain a
suitable operating temperature while coasting, for
example, when no hot gases are flowing past the
oxygen sensor.
The heating element in the HO2S is a PTC
(positive temperature coefficient) resistor. The
heating element is supplied with battery voltage as
soon as the Powertrain Control Module relay
engages. The HO2S is earthed via the PCM. As
the heating current is high when the element is
cold, it is limited via PWM in the PCM until a certain
