Abstract
The emission ratio of a modern fleet with a higher percentage of diesel vehicles was measured and the impact of the new emission control technologies on nitrous acid (HONO) were evaluated. The emission ratio measured was approximately 50% higher than the most commonly used 0.8%. Positive correlation between HONO and black carbon (BC) suggests that HONO and BC were emitted together, while the lack of correlation between HONO/NOxand BC, suggests that the BC-mediated conversion of NO2to HONO in the dark was insignificant immediately after emission. Modeling studies handle the BC-mediated HONO formation in the atmospheric chemistry module rather than make correction at the emission source.
