Trends of NO-, NO_2-, and NH_3-emissions from gasoline-fueled Euro-3- to Euro-4-passenger cars

摘要

Vehicular emissions of reactive nitrogen compounds (RNCs) such as nitric oxide (NO), nitrogen dioxide (NO_2), and ammonia (NH_3) have a substantial impact on urban air quality. NO and NO_2 support the photochemical formation of ozone, and NH3 is involved
