In preparation for compliance with California's SULEV standard and the Euro STEP-4 standard, which will take effect in 2004 and 2005, respectively, planar exhaust gas sensors (oxygen sensor and air/fuel ratio sensor), required for fast light-off and high detection accuacy for engine exhaust feedback control, have been developed. For fast light-off time, the integration of sensor and heater elements was applied using the Alumina/Zirconia joining technique. In addition, a low temperature dependence on air/fuel ratio sensor was obtained to form the diffusion resistance layer controlling the micropore diameter and mixing chamber on the exhaust electrode. With these developments, the air/fuel ratio sensor provides high detection accuracy for a wide range of air/fuel ratios from rich to lean.
