Potential and pitfalls in the use of dual exhaust gas oxygen sensors for three-way catalyst monitoring and control

Although it is known that exhaust gas oxygen (EGO) sensors are sensitive to gas composition, even at a constant air-fuel ratio (AFR), its significance in dual EGO sensor based catalyst control and on-board diagnostic systems has not been fully recognized. The (time varying) difference in gas composi...
