Emission Control Technologies for Reduction of NOx and Particulate Matter from Automotive Diesel Engines
Abstract: In consequence of their efficiency and torque, diesel engines have long been valued, especially for heavy-duty applications. But worries about their emissions—especially those of nitrogen oxides (NOx) and particulate matter (PM)—have prompted stricter laws all around the world. Modern emission control technologies for lowering NOx and PM emissions from automotive diesel engines are reviewed in this paper. There is discussion of several methods, such as diesel particulate filters (DPF), selective …

Emission Reduction Strategies in Diesel and Gasoline Engines: Progress and Future Directions
Abstract: Abstract The global transportation sector remains a significant contributor to greenhouse gas emissions and air pollution, necessitating continuous advancements in emission reduction strategies for internal combustion (IC) engines. Diesel and gasoline engines, despite their efficiency and widespread use, produce harmful pollutants, such as nitrogen oxides (NOx), particulate matter (PM), and carbon monoxide (CO). These emissions contribute to serious environmental and health issues, including global warming, respiratory diseases, and ecosystem degradation. …

Reactive Separation for Biodiesel Purification Using Hybrid Membrane Systems
Abstract: Biodiesel produced through transesterification typically contains several impurities, including residual glycerol, unreacted methanol, soaps, water and homogeneous catalysts, all of which reduce fuel quality and hinder compliance with EN 14214 and ASTM D6751 standards. Conventional purification techniques such as water washing, centrifugation and vacuum distillation are energy-intensive, generate large volumes of wastewater and often fail to efficiently remove polar contaminants. To overcome these limitations, this study examines a reactive separation …

Impact of Exhaust Gas Recirculation on NOx Emissions and Efficiency in Diesel Engines
Abstract: Abstract Exhaust gas recirculation (EGR) has emerged as a pivotal strategy to reduce nitrogen oxide (NOx) emissions from diesel engines, which significantly contribute to air pollution and environmental degradation. NOx emissions pose serious concerns due to their role in forming smog, acid rain, and adverse health impacts. By recirculating a portion of the exhaust back into the intake manifold, EGR reduces these emissions by restricting the manufacturing of NOx and …
