Research ArticleOpen accessIn the abstractSequential Remediation Processes for Effective Removal of Oil from Contaminated SoilsDeepika Dave, Reema Alharathi, Abdel GhalyProblem statement: Over 2.2 billions of oil and oil products were transported every year and often these activities can result in air, water and soil contamination. Expousure to petroleum products can cause health problems to humn and animals and affect marine animals and wildlife habitats. Approach: The objective of this study was to developed a technology for the remediation of … …American Journal of Environmental Sciences, Vol. 7, Issue 5 · 18 Nov 2011 · 8,183 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Effect of Bio-Fuel Blends and Fuel Injection Pressure on Diesel Engine Emission for Sustainable EnvironmentKandasamy Muralidharan, Palanisamy GovindarajanProblem statement: Diesel engine emits more pollutants to atmosphere causing air pollution. This necessitates the search of a renewable alternate fuel which is environment friendly. The objective of this research was to investigate the environmental aspects of pongamia bio-fuel in a single cylinder diesel engine with the influence of fuel injection pressure. Approach: Bio-fuel was prepared from non-edible Pongamia pinnata … …American Journal of Environmental Sciences, Vol. 7, Issue 4 · 10 Oct 2011 · 7,311 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSynthesis of Zeolite A from By-Product of Aluminum Etching Process: Effects of Reaction Temperature and Reaction Time on Pore VolumeKanokorn Hussar, Sombat Teekasap, Nisakorn SomsukProblem statement: Increasing of the carbon dioxide (CO2) concentration in the atmosphere creates a global warming. Zeolite is used as CO2 absorbent. Approach: By-products from aluminum etching process, which carry a large amount of Al2O3 content, are useable as raw materials for synthesis zeolites type A using hydrogel process. A pore volume of zeolites is the key to achieve high … …American Journal of Environmental Sciences, Vol. 7, Issue 1 · 28 Feb 2011 · 7,836 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEmission and Combustion Characteristics of Si Engine Working Under Gasoline Blended with Ethanol Oxygenated Organic CompoundsDhanapal Balaji, Periyasamy Govindarajan, Jayaraj VenkatesanProblem statement: The objective of this study is to investigate the effect of using unleaded gasoline and additives blends on Spark Ignition engine (SI engine) combustion and exhaust emission. Approach: A four stroke, single cylinder SI engine was used for conducting this study. Exhaust emissions were analysed for Carbon Monoxide (CO), Hydrocarbon (HC) and Oxides of Nitrogen (NOx) and carbon … …American Journal of Environmental Sciences, Vol. 6, Issue 6 · 31 Dec 2010 · 7,138 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEnvironmental Assessment of a Diesel Engine Under Variable Stroke Length and Constant Compression RatioJehad A.A. Yamin, Eyad S.M. Abu-NamehIn the light of the energy crisis and the stringent environmental regulations, diesel engines are offering good hope for automotive vehicles. However, lot of work is needed to reduce the diesel exhaust emissions and give the way for full utilization of the diesel fuel's excellent characteristics. This paper presents a theoretical study on the effect of variable stroke length technique … …American Journal of Applied Sciences, Vol. 4, Issue 5 · 31 May 2007 · 6,732 accessesView PDF Cite
