With the latest 3 Cavity Design.
The sensing element is a ceramic chip that consists of a heating circuit, small passage leading into 3 cavities, oxygen pumping circuit and NOx decomposition circuit.
1st Cavity: Exhaust gas under the first cavity through diffusion barrier
2nd Cavity: NO2 present in the exhaust gas is replaced with NO
3rd Cavity: NO enters the third cavity and 2NO→N2 + O2 at M2 electrode
