AbstractCO, THC, NOx, and PM emission factors of 51 light-duty gasoline vehicles (LDGVs) spanning the emission standards from Euro 2 to Euro 5 were measured by a chassis dynamometer. High frequencies of high-emitting vehicles were observed in Euro 2 and Euro 3 LDGV fleet. 56% and 33% of high-emitting vehicles contributed 81%–92% and 82%–85% of the emissions in Euro 2 and Euro 3 test fleet, respectively. Malfunctions of catalytic convertors after high strength use are the main cause of the high emissions. Continuous monitoring of a gasoline vehicle dominated tunnel in Shanghai, China was conducted to evaluate the average emission factors of vehicles in real-world. The results indicated that the emission factors of LDGVs were considerably underestimated in EI guidebook in China. The overlook of high-emitting vehicles in older vehicle fleet is the main reason for this underestimation. Enhancing the supervision of high emission vehicles and strengthening the compliance tests of in-use vehicles are essential measures to control the emissions of in-use gasoline vehicles at the present stage in China.
Highlights51 in-use LDGVs were tested using a chassis dynamometer in Shanghai, China.Continuous monitoring in a gasoline vehicle dominated tunnel were conducted in Shanghai, China.Emission factors of LDGVs were determined based on dynamometer test and tunnel experiment.High-emitting vehicles contributed the majorities of emissions from older vehicles in Shanghai, China.Emission factors of LDGVs were underestimated due to the overlook of high-emitting vehicles in the previous studies in China.
