NOx Sensors - DieselNet

As with O 2 and NOx sensors, the NH 3 sensor relies on O ion conductivity. An NH 3 sensing electrode is selective to NH 3 so that only the amount of O ions required to oxidize NH 3 will be conducted from the reference electrode through the yttria doped zirconia solid electrolyte. The current is then proportional to the amount of NH 3 …

Selective Catalytic Reduction

The tendency of NH 4 NO 3 formation can also be minimized by supplying into the gas stream less than the precise amount of NH 3 necessary for the stoichiometric reaction with NOx (1 to 1 mole ratio). When the flue gas contains sulfur, as is the case with diesel exhaust, SO 2 can be oxidized to SO 3 with the following formation of H 2 SO 4 upon reaction with H 2 O. These reactions are the same ...
