Heated Oxygen Sensor

•

The HO2S is located behind the DPF and detects the oxygen concentration in the
exhaust gas. The HO2S is a wide range type oxygen sensor and uses the same
operating principle as the wide range oxygen sensors on petrol engines. It generates a
clear electrical signal in a wide range from

λ

= 0.7…

∞

(

∞

= air with 21 % oxygen). As a

result, the sensor is also capable of detecting the oxygen concentration in the exhaust
gas of a diesel engine, which generally works with an excess-air factor of

λ

∼

1.4 (at full

load) to

λ

∼

3.4 (at idle).

•

The information of the HO2S is used for the calculation of the soot amount burnt off in
the DPF.
