Secondary aerosol formation from engine exhaust emissions

该项目旨在研究使用替代燃料的车辆产生的活性挥发性有机化合物在二次有机气溶胶（SOA）形成和演变中的作用。项目的预期结果包括对SOA形成的机制和前体的极大改进的理解。这些好处应该提供制定车辆排放法规所需的知识，这些法规可以适当地控制城市空气污染事件，因为其形成的机制和前兆将得到更好的了解。该项目还将提供一个实验性框架，指导政策的制定，并提供制定改善空气质量和健康战略所需的科学。

This project aims to investigate the role of reactive volatile organic compounds from vehicles using alternative fuels in the formation and evolution of secondary organic aerosols (SOA). Expected outcomes of the project include greatly improved understanding of the mechanisms and precursors of SOA formation. The benefits should provide the knowledge needed to set vehicle emission regulations that can properly control urban air pollution episodes because the mechanisms and precursors of its formation will be better understood. The project will also provide an experimental framework that will guide policy formulation and provide the science needed for development of strategies to improve air quality and health.
