TL;DR: In this paper, the authors implemented real-world tests in Nanjing, China for measuring emission factors (EFs) of air pollutants, including Carbon Monoxide (CO), Hydrocarbon (HC), Nitrogen Oxides (NOx), and Particulate Matter (PM) from ten construction machines in three operational modes (idling, moving, and working) with a portable emission measurement system.

TL;DR: In this article , monetary impact values of exhaust and non-exhaust emissions emitted from internal combustion engine vehicles (ICEVs) and their equivalent EVs from an economic-environmental perspective, expressed as monetary impact value, were calculated according to the emission factors and damage costs of these pollutants.
25 citations
TL;DR: In this article, the effect of the electrification of small, medium, and large internal combustion engine (ICE) passenger cars on the levels of total particulate matter (PM) was evaluated.
19 citations
TL;DR: In this article, the effect of SCR and ACCT systems on the correlations between driving behaviours and NOx emissions were explored based on worldwide harmonized light vehicle test cycles (WLTC), and the results indicated that vehicle fuel consumption rates almost linearly increased with acceleration when the acceleration was higher than 0.5 m/s2.

TL;DR: In this paper, two direct injection (DI) petrol passenger cars and a diesel passenger car are tested on the same routes, driven by the same driver, and instantaneous NOx and PN emissions are monitored by a portable emission measurement system in the tests.

Abstract: Diesel particulate filter (DPF) is considered as an effective method to control particulate matter (PM) emissions from diesel engines, which is included in the mandatory installation list by more and more national/regional laws and regulations, such as CHINA VI, Euro VI, and EPA Tier3. Due to the limited capacity of DPF to contain PM, the manufacturer introduced a method of treating deposited PM by oxidation, which is called regeneration. This paper comprehensively summarizes the most advanced regeneration technology, including filter structure, new catalyst formula, accurate soot prediction, safe and reliable regeneration strategy, uncontrolled regeneration and its control methods. In addition, due to the change of working conditions in the regeneration process, the additional emissions during regeneration are discussed in this paper. The DPF is not only the aftertreatment device but also can be combined with diesel oxidation catalyst (DOC), selective catalytic reduction (SCR) and exhaust recirculation (EGR). In addition, the impact of DPF modification on the original system of some old models has been reasonably discussed in order to achieve emission targets.

TL;DR: In this paper, the authors investigated the impact of driver behaviour on real driving emissions (RDE) and found that novice drivers are less skilled or more aggressive than experienced drivers in using the accelerator pedal, leading to higher vehicle and engine speeds.
