The present study focuses on the optimization in the use of non-petroleum fuel derived from waste fish oil fuels, as a replacement for petroleum diesel fuel for compression ignition engine. The study comprises of comparison between results of fish oil biodiesel-diesel blends on a compression ignition engine. Fuel properties such as viscosity, density, heat value of fuel, cetane number and a fla...

UNLABELLED Road transport emissions are a major contributor to ambient particulate matter concentrations and have been associated with adverse health effects. Therefore, these emissions are targeted through increasingly stringent European emission standards. These policies succeed in reducing exhaust emissions, but do not address "nonexhaust" emissions from brake wear, tire wear, road wear and ...

Residential wood combustion is the main source of elevated concentrations of fine particulate matter (PM2.5) during winter in many towns of Tasmania, Australia. A commercially available firebox catalyst in Australia has previously been shown to reduce visible smoke emissions and the manufacturer reports reductions in particle emissions generated from individual wood heaters in laboratory settin...

This paper presents the first comprehensive estimates of particulate emissions in China by size distribution and major components. Using a technology-based emission inventory approach, we are able to classify particulate emissions into three size ranges, TSP, PM10 and PM2.5, and identify the contributions of black carbon (BC), organic carbon (OC), Ca and Mg. Total particulate emissions are esti...

Numerous laboratory studies report carbon monoxide, hydrocarbon, and particulate matter emission reductions with a slight nitrogen oxides emission increase from engines operating with biodiesel and biodiesel blends as compared to using petroleum diesel. We conducted a field study on a fleet of school buses to evaluate the effects of biodiesel use on gaseous and particulate matter fuel-based emi...

Fire management specialists in the southeastern United States needing guides for predicting or assessing particulate matter emission factors, emission rates, and heat release rate can use the models presented in this paper for making these predictions as a function of flame length in the palmetto-gallberry fuel type.

Public concerns related to air quality impacts of intensive livestock and poultry operations have grown drastically over the recent years. Pollutants of concern are particulate matter, ammonia, methane, hydrogen sulfide, volatile organic compounds, and odors. However, there is a general paucity on character, amount, and dispersion of livestock air pollutants. Despite dramatic knowledge gaps, th...

This paper presents a non-contact sensing system for nanosized suspended particulate matter (SPM) measurements using laser-induced incandescence (LII) and laser-induced breakdown spectroscopy (LIBS). The elemental composition and density of the SPMs are determined using LIBS, and particulate size measurements are accomplished using LII. Typically, temporally resolved LII enables measurement of ...

Current regulation aimed at reducing inorganic atmospheric fine particulate matter (PM2.5) is focused on reductions in sulfur dioxide (SO2) and oxides of nitrogen (NO(x) = NO + NO2); however, controls on these pollutants are likely to increase in cost and decrease in effectiveness in the future. A supplementary strategy is reduction in ammonia (NH3) emissions, yet an evaluation of controls on a...
