Study on Exhaust Emission Test of Diesel Vehicles Based on PEMS
Guor et al. (2020) carried out a study of the macro-model of vehicle exhaust emissions. The study tested the gas emissions of three different types of diesel touring vehicles using the PEMS system, and it examined the relationship between their emission characteristics, vehicle speed, and acceleration. The findings indicated that the emission factor has a high positive association with vehicle speed and acceleration, indicating that raising driving speed and decreasing the frequency of acceleration may both significantly lower pollutant emissions.
