    Abstract: A system and a method of operating the system are presented. The system includes a first sensor, a second sensor and a catalyst. The catalyst is located between the first sensor and the second sensor in the path of an exhaust stream from an engine. The first sensor and the second sensors include noble metal electrodes, and are configured to measure concentration of a gaseous species and produce first and second sensor signals respectively. The system further includes a sulfur detector that is configured to receive the first and second signals, and configured to determine a sulfur concentration in the exhaust stream with a lambda value less than 1. The sulfur detector is configured to detect the concentration of sulfur by performing a calculation involving the first and second sensor signals; and by producing an output signal based on the determined sulfur concentration.

    Abstract: A passive mid bed air injection apparatus for an engine includes a three way catalyst positioned in an exhaust stream of the engine. The three way catalyst reduces NOx, CO and HC from the exhaust stream. The three way catalyst includes an ammonia slip catalyst positioned in the exhaust stream of the engine. The ammonia slip catalyst is positioned downstream from the three way catalyst and oxidizes NH3 and CO from the exhaust stream. The three way catalyst includes an oxygen input disposed between the three way catalyst and the ammonia slip catalyst such that the oxygen input delivers air downstream from the three way catalyst and upstream from the ammonia slip catalyst. The oxygen input receives the air from a charged side of a forced induction device and delivers the air to the exhaust stream entering the ammonia slip catalyst. An associated method also provided.
