Research ArticleOpen accessIn the abstractEffect of Metalloid Compound and Bio-Solution Additives on Biodiesel Engine Performance and Exhaust EmissionsKaroon Fangsuwannarak, Kittichai TriratanasirichaiThe purpose of this study is to perform comparative analysis of the effect of the different fuel additives as polymer based-bio-solution, natural organic based-bio-solution and nano-titanium metalloid (TiO2) compound on the performance parameters and exhuast emissions of a pickup Diesel engine, operating on commercial Diesel fuel (D) and B5 palm biodiesel (95% D+5% palm oil). The basic properties of the … …American Journal of Applied Sciences, Vol. 10, Issue 10 · 5 Sep 2013 · 7,675 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe 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 PDF Cite

Research ArticleOpen accessIn the abstractDynamic Modelling of an Industrial Smelter Furnace and Converter Off-gas SystemHelen Shang, Megan Dillabough, Phillip Nelson, Bryan SaltIn smelters, metal ores or concentrates are smelted to reduce a metal oxide to a metal through a series of reactions and processes. In a smelting process, a large amount of off-gas emissions are often generated, which can cause serious environmental and plant hygiene problems if not properly treated. Off-gas systems extract and treat the off-gas emissions, and ensure that … …American Journal of Environmental Sciences, Vol. 4, Issue 1 · 29 Feb 2008 · 7,158 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEnvironmental Management Systems in Local Authorities: The Case Study of the Cesana Torinese Municipality, a Turin 2006 Olympic SiteSerena Botta, Claudio ComoglioEnvironmental certification according to the ISO 14001 standard and EMAS regulation represents an efficient tool for those organizations who want to continuously improve their environmental performances. Even though first thought up for application to the industrial section, in recent years these schemes have also proved to be valid in organizations with territorial competences, such as local authorities. The case study … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 7,263 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThermodynamic Analysis of an Absorption/Compression Refrigeration System Using Geothermal EnergyL. Kairouani, E. NehdiThis article presents the potential use and exploration of geothermal energy for cooling applications using a combined absorption/compression system. The considered system uses R134a for the compression part and the cool water-ammonia for the absorption part of the installation. The geothermal temperature source is in the range 343-349K, the condensation temperature is 308 K, and in order to produce ice, … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 7,559 accessesView PDF Cite
