Research ArticleOpen accessIn the abstractThe Dynamics of the Otto EngineRelly Victoria Virgil Petrescu, Raffaella Aversa, Taher M. Abu-Lebdeh et al.The dynamic calculation of a certain mechanism and of the piston crankshaft mechanism, used as the main mechanism for Otto internal combustion engines, also implies the influence of external forces on the actual, dynamic kinematics of the mechanism. Take into account the strong and inertial engine forces. Sometimes weight forces can also be taken into account, but their influence is … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 20 Feb 2018 · 7,526 accessesView PDFCite
Research ArticleOpen accessIn the abstractCylinder Pressure Variations of the Fumigated Hydrogen-Diesel Dual Fuel CombustionBoonthum Wongchai, Porranat Visuwan, Sathaporn ChuepengCylinder pressure is one of the main parameters of diesel engine combustion affecting several changes in exhaust gas emission composition and amount as well as engine useful power, specifically when alternative fuels are used. One among other alternative fuels for diesel engine is hydrogen that can be used as fumigated reagent with air prior to intake to engine in order … …American Journal of Applied Sciences, Vol. 9, Issue 12 · 12 Dec 2012 · 7,443 accessesView PDFCite
