Objective:
The objective of this project was to improve emission inventories of gas-phase low-volatility organic compounds (LVOCs) from mobile sources, providing inputs to microphysical/ chemical modules important for air quality predictions. Present inventories of LVOCs are limited to total mass, or concentrations of only a few species, with little information about the chemistry or volatility of the total emissions, both of which are important for understanding their influence on the formation of new particles and/or secondary organic aerosol. The specific objectives were (1) the development and demonstration of a novel technique for the volatility-resolved measurement and characterization of LVOCs; (2) the application of this technique towards the measurement of LVOCs from diesel engines, as a function of engine load, engine power, and emissions control technology; and (3) the use of this technique for characterizing LVOC emissions under real-world (in-use) conditions.
