Research ArticleOpen accessIn the abstractPM Emissions in a Urban ContextEnrico Brizio, Giuseppe Genon, Stefania BorsarelliWithin a urban environment, three different sources of particulate matter should be considered: heating plants using different combustibles (natural gas, gas oil, fuel oil, wood), industrial plants placed in the surrounding area, traffic. While the effects of the first two origins can be easily calculated on the basis of existing emission factors, the PM emissions from traffic are of two … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 6,876 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Hydroxylated Compounds on Properties and Emission of Palm BiodieselRoila Awang, Choo Yuen MayThe Malaysian Palm Oil Board (MPOB) attempted the search for a viable alternative fuel leading to a possible substitution to the conventional diesel since 1982, using palm oil derived fuel. Numerous studies have shown that most exhaust emission encountered with conventional diesel fuel are reduced with biodiesel,with the exception of nitrogen oxides (NOx). This paper is reported on the effect … …American Journal of Applied Sciences, Vol. 4, Issue 2 · 28 Feb 2007 · 7,145 accessesView PDFCite
Research ArticleOpen accessIn the abstractNondestructive Test Using a 3D Computer Vision System for Damage Detection of StructuresTaylor M.V. Szeto, Sun YiStructures that do not have a definitive map nor a clearly known state of health may exist underground, beyond our reach and in unsuitable environments. Nuclear facilities contain underground tunnels that exhaust hazardous gases. Industry has miles of sewage lines beneath it that emit flammable and toxic gases. Regular inspection and maintenance is an essential part of failure prevention, however, … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 2 Jun 2018 · 8,263 accessesView PDFCite
Research ArticleOpen accessIn the abstractCombustion, Performance and Emission Characteristics of Diesel Engine with Neem Oil Methyl Ester and its Diesel BlendsL. Prabhu, S. Sathish Kumar, M. Prabhahar, K. RajanBiodiesel, an alternative fuel is derived from the fats of animals and plants. As energy demands increase and fossil fuels are limited, research is directed towards alternative renewable fuels. The main advantages of using this alternative fuel are its renewability, biodegradability and better quality of exhaust gases. It is technically competitive and environmentally friendly alternative to conventional petro-diesel fuel for … …American Journal of Applied Sciences, Vol. 10, Issue 8 · 24 Jul 2013 · 7,264 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of Kinetic Correction Coefficient of Fluid Flow Using a Generic Multiple Orifice Physical Scale Model StructureEmmanuel M. AdigioProblem statement: Diesel particulate filters are fast becoming integral parts of diesel engines, light and heavy duty, due to their potential in the reduction of particulate matter from exhaust gases and their noise muffling property. Consequently, several researchers are developing mathematical models for the study of fluid flow through the filter substrate and in the aiding of filter systems design. … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,557 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordThe Effects of Excess Oxygen to Mixture on the Gasses Emissions of a Gasoline EngineWaleed MomaniProblem statement: The effects of excess feeding oxygen to the fuel-air mixture on the exhausts gasses emissions concentrations are investigated here. It is known that spark-ignition and diesel engines are considered as major sources of urban air pollution; such pollutants are CO2, CO, HC. Hence, many techniques have been used to decrease such emissions such as: Catalytic converters, oxidizers, traps … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 7,517 accessesView PDFCite
