Physical, chemical, and cell toxicity properties of mature/aged particulate matter (PM) trapped in a diesel particulate filter (DPF) along with the results from freshly produced PM of a diesel engine

Determination of Vehicle Emission Rates for Ammonia and Organic Molecular Markers Using a Chassis Dynamometer

“…Diesel engines are extensively utilized in various applications such as vehicles, ships, and construction machinery due to their high thermal efficiency, cost-effectiveness, and durability [1,45]. However, the widespread use of diesel engines also contributes to significant environmental pollution issues [32]. To mitigate PM emissions, the installation of DPF in diesel vehicles has become crucial for effective exhaust gas emission control, considering the substantial role of diesel vehicles as a major source of PM production [1].…”

“…To mitigate PM emissions, the installation of DPF in diesel vehicles has become crucial for effective exhaust gas emission control, considering the substantial role of diesel vehicles as a major source of PM production [1]. Nevertheless, despite the oxidation and combustion of most PM during vehicle operation, non-volatile substances such as elemental carbon, ash, and soot persist [7,32,45]. Hence, this study focused on analyzing the carbon content by capturing exhaust gas during DPF regeneration (DPFre) using EURO6 vehicles (EURO6 DPFre).…”

Unveiling the Surface Chemical Reactions during Multi-Phase Catalytic Oxidation of Soot on Nanoengineering/Interfacing/Doping-Prepared Mn-CeO2 Catalysts Using TG-MS and Operando DRIFTS-MS

“…4 DPM is a byproduct of incomplete diesel fuel combustion and contains mainly soot as high as 89.9%. 5 Soot is one kind of carbon and has an ignition temperature above 550 °C, which is higher than the temperature of the exhaust gas. 6 DPM emissions have detrimental effects on human health and have the potential to be carcinogenic.…”

“…Due to their low operating costs, excellent durability, and energy efficiency, diesel engines are still the primary power sources for commercial transportation. − However, diesel engine vehicles emit a lot of diesel particulate matter (DPM) . DPM is a byproduct of incomplete diesel fuel combustion and contains mainly soot as high as 89.9% . Soot is one kind of carbon and has an ignition temperature above 550 °C, which is higher than the temperature of the exhaust gas .…”

“…Soot is one kind of solid-state particle with a density of 1.847 g·cm –3 . Soot particle sizes range from a few nanometers to several hundred nanometers. ,, The contact between the catalyst and soot is thought to be one of the most important factors impacting the catalytic soot combustion because soot particles cannot pass through the micropores/mesoporous pores of most nanostructured catalysts. Studies have revealed that the catalyst’s shape and outer surface mostly determine how the catalyst interacts with soot .…”
