Possibilities of Simultaneous In-Cylinder Reduction of Soot and NOx Emissions for Diesel Engines with Direct Injection

open access: yesInternational Journal of Rotating Machinery, 2008
Up to now, diesel engines with direct fuel injection are the propulsion systems with the highest efficiency for mobile applications. Future targets in reducing CO2 -emissions with regard to global warming effects can be met with the help of these engines.

2D CFD Simulation of Water Injection Strategies in a Large Marine Engine

open access: yesJournal of Marine Science and Engineering, 2019
A two-dimensional computational fluid dynamics (2D CFD) simulation of a low-speed two-stroke marine engine simulation was performed in order to investigate the performance of 2D meshes that allow the use of more complex chemical schemes and pollutant ...

A Mechanochemical Kolbe–Schmitt Reaction: Catechol Carboxylation Provides Building Blocks for Renewable Plasticizers

open access: yesAngewandte Chemie, EarlyView.
A mechanochemical Kolbe–Schmitt reaction of disodium catecholate enables the synthesis of mono‐ and dicarboxylated catechols at low temperature and CO2 pressure. Directly derivatizing the resulting carboxylic acid and phenolic moieties in the obtained mixture provides plasticizer blends with efficiencies competitive to commercial benchmarks.

Soot emissions of mutually synchronized candle flames

open access: yes, 2023
Abstract The evolution of soot particles from steady flames is relatively well explored compared to the evolution of soot particles from oscillating flames. Therefore, the present study aims to characterize soot particles' size evolving from self-excited oscillating flames, which are produced from the burning of two bundles of candles (4 ...

Numerical investigation of soot mass concentration in compression ignition diesel engine

open access: yesJournal of Mechanical Engineering and Sciences, 2016
Soot particles, carbon monoxide, oxides of nitrogen, oxides of sulphur, and hydrocarbon are the emissions produced from diesel engine combustion. Those emissions species are undesirable since they give detrimental impacts to the atmosphere and human ...

Char dominates black carbon aerosol emission and its historic reduction in China

open access: yesNature Communications, 2023
Emission factors and inventories of black carbon (BC) aerosols are crucial for estimating their adverse atmospheric effect. However, it is imperative to separate BC emissions into char and soot subgroups due to their significantly different ...

Emissions of soot particles from heat generators

open access: yesJournal of Physics: Conference Series, 2017
«Soot carbon» or «Soot» - incomplete combustion or thermal decomposition particulate carbon product of hydrocarbons consisting of particles of various shapes and sizes. Soot particles are harmful substances Class 2 and like a dust dispersed by wind for thousands of kilometers. Soot have more powerful negative factor than carbon dioxide. Therefore, more
