Abstract

Abstract:

In order to investigate the ammonia emission characteristics of road motor vehicles, the Motor Vehicle Emission Simulator (MOVES) model was used to localize the model parameters with Taiyuan City as the research object, and the calculation method of the emission standard percentage of different models was proposed while improving the accuracy of parameter localization, and finally the ammonia emission inventory of motor vehicles was obtained and the ammonia emission characteristics of motor vehicles in Taiyuan City were analyzed from four perspectives of models, time, speed and space, respectively. The results show that the ammonia emissions of motorcycles, private cars, large buses, minivans, and large trucks in Taiyuan in 2021 were 4.2, 441.8, 5.05, 130.4 tons, and 49.4 tons, respectively; the order of the average ammonia emissions per unit mileage of different vehicle types was large trucks > large buses > minivans > private cars > motorcycles; the lower ammonia emissions can be obtained when the driving speeds of on-road motor vehicles is in the range of 25 to 65 km/h. The research results can provide a theoretical reference for regulating ammonia emissions from road motor vehicles.

Key words: ammonia emission, motor vehicle emission simulator (MOVES) model, parameter localization, emissions inventory
