O2 Sensors


General description

Oxygen sensor is installed in the exhaust gas pile to measure the oxygen content and find out whether the combustion of gasoline and air is stoichometric A/F ratio.
And in this status the catalytic converter has maximum conversion efficiency on HC,CO and NOx in the exhaust gas.
When the inside and outside of the sensor element has different oxygen concentration, the oxygen sensor can detective it and transform to voltage signal.
