Research ArticleOpen accessIn the keywordsEnvironmental 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 PDFCite
Research ArticleOpen accessIn the abstractGaseous Emissions and Combustion Efficiency Analysis of Hydrogen-Diesel Dual Fuel Engine under Fuel-Lean ConditionPrateep Chaisermtawan, Sompop Jarungthammachote, Sathaporn Chuepeng, Thanya KiatiwatExhaust gas emissions from diesel engine combustion using alternative fuel may change in their quantities that can affect exhaust gas after-treatment devices and environmental ambient. This study presents theoretical analysis of combustion generated emissions and efficiency of hydrogen-diesel duel fuel in fuel-lean condition. A chemical equilibrium method by minimizing Gibbs free energy is employed to estimate exhaust gas products from … …American Journal of Applied Sciences, Vol. 9, Issue 11 · 1 Sep 2012 · 7,509 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Prickly Poppy Methyl Ester Blends on Ci Engine Performance and Emission CharacteristicsP. Lawrence, P. Koshy Mathews, B. DeepanrajProblem statement: The aim of this research was to investigate the effect of using Prickly poppy methyl ester as a fuel blend on Diesel engine (CI engine) performance and exhaust emission. Approach: Short-term engine performance tests were conducted to evaluate and compare the use of various diesel fuel supplements at blend rations of 60/40, 70/30, 80/20, 90/10, in a standard, … …American Journal of Environmental Sciences, Vol. 7, Issue 2 · 26 May 2011 · 7,136 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Investigation on Performance and Emission Characteristics of Low Heat Rejection Diesel Engine with Ethanol as FuelP. Lawrence, P. Koshy Mathews, B. DeepanrajProblem statement: Depleting petroleum reserves on the earth and increasing concerns about the environment leads to the question for fuels which are eco-friendly safer for human beings. The objective of present work was to investigate the effect of coating on piston, cylinder head and valves of a Diesel engine on the performance and emission characteristics of exhaust gases using wet … …American Journal of Applied Sciences, Vol. 8, Issue 4 · 18 Apr 2011 · 7,219 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 · 7,553 accessesView PDFCite
Research ArticleOpen accessIn the abstractNumerical and Analytical Study of Exhaust Gases Flow in Porous Media with Applications to Diesel Particulate FiltersSuleiman Abu-EinProblem statement: The importance of diesel particulate filter has been increased later because of its ability in making emission reduction of the exhaust gasses. Diesel Particulate Filters (DPF) do two important jobs: gas emissions reduction and noise reduction, the pores spread inside the DPF store some gases and soot emissions and on the other side it prevents some sound or … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,161 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 · 7,144 accessesView PDFCite
