Electrical system
It requires no external power but must reach a high
operating temperature (closed loop) to operate
properly: that is why there is a heating circuit in-
side.
Closed loop lambda control varies the mixture to
continuously oscillate the state of the probe be-
tween rich and lean and it is used throughout the
range of the emission cycle.
A stoichiometric air/fuel ratio allows the maximum
emission reduction efficiency of the catalyst; how-
ever, under certain operating conditions, the opti-
mum air/fuel ratio may deviate from the stoichio-
metric value. In particular, at full load, the ratio
must be very different to the rich value for reasons
of performance and reliability.
