Research ArticleOpen accessIn the keywordsEnvironmental Pollution Assessment of Different Diesel Injector Location Of Direct-Injection Diesel Engines: Theoretical StudyEyad S. M. Abu-Nameh, Jehad A. A. YaminAn Analytical investigation on the effect of injector location of a four-stroke DI diesel engine on its pollutants’ emissions was carried out under different injector locations ranging from central to peripheral at different engine speeds ranging from 1000 rpm to 3000 rpm. The simulation results clearly indicated the advantages and disadvantages of the central location over the peripheral one. It … …American Journal of Environmental Sciences, Vol. 4, Issue 2 · 30 Apr 2008 · 6,467 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Mathematical Modeling of the Turbulence Combustion Biodiesel in a Compression Ignition Engine: Theoretical FrameworkFrancis Mouzong Bongne, Zacharie Merlin Ayissi et al.The present work proposes a new model for biodiesel combustion in an internal combustion engine. This model first includes the balance equations of gas dynamics with heat release. Secondly, a model with special properties that take into account turbulence effects is incorporated. The chemical models implemented in this study are for a biofuel used at less than 100% and for … …American Journal of Engineering and Applied Sciences, Vol. 17, Issue 4 · 30 Sep 2024 · 5,021 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Study of Diesel Engine Generator Performance and Emission Characteristics Using a Mixture of Jatropha Oil and Rubber Seed Oil Biodiesels Along a Two-Step TransesterificationFana Gebremedhin Gebremichael, Joao Fernando ChidamoioThis study investigates the performance and emission properties of engine-generator powered using various dual biodiesel mixes prepared from two inedible feedstock jatropha and rubber. Jatropha and rubber oils had high acid values, which were 13.96 and 27.91 mg KOH/g, respectively. Therefore, a two-step transesterification process was conducted to lower the acid value to 0.28 and 0.42 mg KOH/g for jatropha … …American Journal of Engineering and Applied Sciences, Vol. 17, Issue 3 · 1 Jul 2024 · 5,124 accessesView PDFCite
