Under laboratory-simulated diesel exhaust conditions, this mixed-phase oxide material was superior to Pt in terms of cost, thermal durability, and catalytic activity for NO oxidation. Oxidation of engine-generated NO to NO 2 is critical in diesel engine emission control for reducing NO x and carbon soot from the tail-pipe exhaust.

Contribution of gasoline and diesel exhaust to SOA over 0% to 50% diesel fuel use. The study determined that, depending on a region’s fuel use, diesel exhaust is responsible for 65% to 90% of vehicular-derived SOA, with substantial contributions from aromatic and aliphatic hydrocarbons.

Some strategies to reduce emissions include running the engine highly dilute, with excess air or with recirculated exhaust gases as part of the combustion charge. Davis (UC Davis), R.Sankaran (ORNL). However, increased dilution leads to increased combustion instability resulting in reduced fuel-economy benefits. Description.
