The oxygen sensor is the oxygen ion concentration sensing ceramic tube inside and outside the difference into
voltage signal output implementation. When the sensing ceramic tube temperature reaches 350 ℃, which has the
characteristics of solid electrolyte. Because of its special material, the oxygen ions can freely through the ceramic
tube. It is the characteristic, the concentration difference into potential difference, thus forming electrical signal
output. If the gas mixture of concentrated. The ceramic tube and oxygen ion concentration is high, the high
potential difference, oxygen ions from the medial to lateral, the higher output voltage (close to 800mV~1000mV);
if the original lean mixture, the ceramic tube and oxygen ion concentration is low, the potential difference is low,
only a small amount of oxygen ions from the medial to lateral, the output voltage is low (close to
100mV~200mV). Signal voltage in the theory of equivalent air-fuel ratio (λ =1) occurred near mutation, see
below.
