Research ArticleOpen accessPhrase in the titleGaseous 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 Effects of Oil Film Shape on Piston Ring and Liner Tribology Under Mixed LubricationAbbas Razavykia, Cristiana Delprete, Eugenio Brusa, Yaser HosseiniMechanical power loss reduction at lubricated reciprocating and rotating components is recognized as an approach to improve the efficiency and to reduce the emissions of Internal Combustion Engines (ICEs). To achieve these goals, the instantaneous investigation of lubrication characteristics is required. Piston ring pack is of paramount importance as it is known as major contributor to frictional losses and energy … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 4 · 10 Nov 2021 · 6,523 accessesView PDFCite
Research ArticleOpen accessIn the abstractPresentation of Four-stroke Engine Design ElementsRelly Victoria Virgil PetrescuHaving escaped the shadow of the global energy crisis by implementing nuclear fission, wind, solar, bioenergy, but also by producing and extracting (deep) gases capable of providing us with planetary reserves for two more. Or at least three thousand years, we have started to relax more energetically, but due to the huge pollution produced by cars, the rules of their … …Journal of Mechatronics and Robotics, Vol. 4, Issue 1 · 28 Apr 2020 · 6,950 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigation on the Performance of Producer Gas Fired Reversible Flat-Bed DryerW. Beno Wincy, M. Edwin, S. Joseph SekharRice is one of the important crops which supplies energy to around 80% of the world population. Paddy drying is an energy intensive process as huge amount of energy is required for drying. Direct combustion of rice husk or wood is followed at the mills to generate heat which is found to be less efficient and highly environment polluting. Hence … …Energy Research Journal, Vol. 10, Issue 1 · 12 Sep 2019 · 7,301 accessesView PDFCite
Review ArticleOpen accessIn the abstractThe Yield of the Thermal EnginesNicolae Petrescu, Florian Ion Tiberiu PetrescuThis paper presents an algorithm for determining the dynamic parameters of the main classic mechanism of internal combustion engines. It shows the distribution of forces (on the main engine mechanism) to internal combustion engines. With these forces and together with the kinematic coupling speeds, the efficiency of the thermal engine is determined. The method applies separately for two distinct situations: … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 14 May 2019 · 6,191 accessesView PDFCite
Research ArticleOpen accessIn the abstractContributions to the Stirling Engine StudyFlorian Ion Tiberiu PetrescuIn the process of transforming thermal energy into mechanical work, among the known thermal machines, the Stirling engine is the one that can achieve the highest yield (theoretically up to the maximum yield of the Carnot cycle), although in practice it is reduced by the properties of gas and materials used such as friction coefficient, thermal conductivity, melting point, breaking … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 4 · 22 Nov 2018 · 10,172 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Quality of Transport and Environmental Protection, Part IRelly Victoria Virgil Petrescu, Aversa Raffaella, Samuel Kozaitis et al.The today main challenge to protect the environment through the development of new and more efficient transportation systems is presented. The absolutely necessary goods distribution and human transfers are polluting and damaging the environment and new solution should be envisaged; the conflicting strategies to adopt new types of environment friendly transportation while maintaining operative the more economically convenient, but largely … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 3 · 8 Sep 2017 · 7,812 accessesView PDFCite
Research ArticleOpen accessIn the abstractModelling and Assessment of Effect of Operation Parameters on Gas Turbine Power Plant Performance using First and Second Laws of ThermodynamicsSunday Olayinka Oyedepo, Richard Olayiwola Fagbenle, Samuel Sunday AdefilaIn this study, modelling of gas turbine engine performance is carried out using thermodynamics relations. The model reveals that the influence of operation parameters such as compression ratio, turbine inlet temperature and ambient temperature has significant effect on the performance of gas turbine engine. Energy and exergy analyses were conducted to evaluate the performance of the selected power plant and … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 3 May 2017 · 7,920 accessesView PDFCite
Research ArticleOpen accessIn the abstractModern Propulsions for Aerospace-Part IIRelly Victoria Virgil Petrescu, Raffaella Aversa, Bilal Akash et al.Speaking about a new engine ionic means to speak about a new aircraft. The paper presents in a short time the actual engines ion chambers (called the ion thrusters) and other new ionic motors proposed by the authors. The engine (ionic propulsion unit of ions, that accelerates the positive ions through a potential difference) is approximately ten times more efficient … …Journal of Aircraft and Spacecraft Technology, Vol. 1, Issue 1 · 25 Apr 2017 · 8,118 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization and Evaluation of Charcoal Briquettes Using Banana Peel and Banana Bunch Waste for Household HeatingSumrit Mopoung, Vijitr UdeyeThe charcoal briquettes from banana peel and banana bunch wastes from dried banana industry for household heating were characterized and evaluated. A 200 L pyrolyzer was used for charcoal and wood vinegar production at 350°C pyrolysis temperature. The percent yield of charcoal and wood vinegar were determined. The effects of clay binder (0-15% w/w) on the properties of charcoal briquettes … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 12 Apr 2017 · 23,049 accessesView PDFCite
