The increase in the number of automobiles leads to an increase in the emission of a large number of pollutants,which has a serious impact on the environment.This article investigates the emission performance of a vehicle under different test conditions using advanced measurement techniques with the aim of reducing pollutant emissions.The study examines in detail typical emissions in urban and high-speed driving,and points out that engine status,operation,and the surrounding environment significantly affect pollution levels.In this paper,the experimental design,data processing,and analysis methods are introduced,and suggestions for improvement are derived.
