Mercedes 1.7-liter DOC+LNT Sulfation/deSulfation study with intracatalyst speciation
Shean Huff, Oak Ridge National Laboratory
Category: Engine and Vehicles Data
Technology: DOC (Diesel Oxidation Catalyst), LNT (Lean NOx Trap)
Exhaust speciation of a DOC+LNT system including intracatalyst samples. The catalyst was examined in the following Sulfur loaded states: (1) Fresh, (2) Mildly Sulfated [i.e., 2900 miles], (3) Moderately Sulfated [i.e., 5300 miles], (4) Heavily Sulfated [i.e., 9100 miles], and (5) deSulfated. Mercedes 1.7l engine operated with in-cylinder rich mode for LNT regeneration. Data from two strategies ("DEM" and "P80"). Exhaust speciation includes NOx, NO, CO, CO2, HC, H2, and O2. Experiments conducted at ORNL as part of DOE sponsored "Measurement and Characterization of NOx Adsorber Regeration and Desulfation" project.
