Effect of Diesel Soot on the Heterogeneous Reaction of NO₂ on the Surface of γ-Al₂O₃

Atmosphere, 2022
Soot and aged soot are often found to be mixed with atmospheric particles, which inevitably affect various atmospheric heterogeneous reactions and secondary aerosol formation.

Effect of Renewable Fuels and Intake O₂ Concentration on Diesel Engine Emission Characteristics and Reactive Oxygen Species (ROS) Formation

Atmosphere, 2020
Renewable diesel fuels have the potential to reduce net CO2 emissions, and simultaneously decrease particulate matter (PM) emissions. This study characterized engine-out PM emissions and PM-induced reactive oxygen species (ROS) formation potential ...

Effect of H2/CO addition on soot formation in ethylene diffusion flame

Frontiers in Energy Research
Coupling the San Diego gas phase reaction mechanism and the Moss Brookes soot model using FLUENT14.0 software, the effect of adding H2/CO on the fuel side on soot formation in an ethylene/air laminar diffusion flame was studied.

Morphology of diesel soot residuals from supercooled water droplets and ice crystals: implications for optical properties

Environmental Research Letters, 2015
Freshly emitted soot particles are fractal-like aggregates, but atmospheric processes often transform their morphology. Morphology of soot particles plays an important role in determining their optical properties, life cycle and hence their effect on ...

First Steps towards a Super-Compact In-Situ Laser-Induced-Incandescence Sensor System

Proceedings, 2019
To realize an actual in-situ Laser-Induced Incandescence (LII) sensor system for measurements in an exhaust pipe of a combustion engine, suitable components for such an application were chosen, integrated in a first prototype and tested.

Effect of Pore Structure on Soot Deposition in Diesel Particulate Filter

Computation, 2016
Nowadays, in the after-treatment of diesel exhaust gas, a diesel particulate filter (DPF) has been used to trap nano-particles of the diesel soot. However, as there are more particles inside the filter, the pressure which corresponds to the filter ...

AIR POLLUTION IN KRAKOW – A GLANCE INTO THE FUTURE FROM A HISTORICAL PERSPECTIVE [PDF]

Acta Geobalcanica, 2017
High concentrations of air pollution probably occurred in Krakow in the nineteenth and early twentieth centuries. Since the late 1960s due to the development of monitoring networks level of air pollution is well documented.

Enhancing soot oxidation using microtextured surfaces

Scientific Reports
Biomass combustion provides energy needs for millions of people worldwide. However, soot accumulation on the combustors’ walls significantly reduces heat transfer efficiency. Herein, we demonstrate how microtextured surfaces minimize soot accumulation by
