Development of NOx Sensors for Heavy Vehicle Applications

Description: The primary gaseous pollutants (excluding CO{sub 2}) produced by combustion of low-sulfur diesel fuel oxides of nitrogen (NO{sub x}), carbon monoxide (CO), and hydrocarbons (C{sub y}H{sub z}). The last two of these can be readily ameliorated by an oxidation catalyst in the O{sub 2}-rich environment of diesel exhaust but NO{sub x} can not.[1] For this reason NO{sub x} remediation strategies such as selective catalytic reduction (SCR) [2, 3] and the lean NO{sub x} trap (LNT) [4, 5] are being acti… more

Real-Time, In Situ Sensor for Control of Ammonia Slip in SCR Installations

Description: In this program, we proposed to demonstrate a compact, rugged, low-cost ammonia sensor with better than {+-}0.2 ppmv lower detection limit and resolution. Extensive design and trade studies indicated that this measurement could be made by exploiting the infrared absorbance of ammonia at 1527 nm to determine concentration. Key features of the design were (1) a electronically-tunable, wavelength-agile diode laser-pumped fiber laser, (2) a unique, low-cost folded path optical cell, and (3) an InGa… more
