Research ArticleOpen accessIn the abstractStructure of a Photovoltaic Electric LocomotiveFlorian Ion Tiberiu PetrescuThe paper proposes to start studies at the global level for the implementation of photovoltaic electric locomotives. The question the author asks is why such trains have not been implemented so far, is there no interest in such a thing? This may avoid the current rush to implement 5G technologies in an already extremely dangerous form for humanity, the rush … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 4 · 16 Nov 2019 · 7,191 accessesView PDFCite
Research ArticleOpen accessIn the abstractNew About the Balancing of Thermal MotorsNicolae Petrescu, Florian Ion Tiberiu PetrescuThe paper presents a new method of balancing the thermal motors, the method that perfectly fits the engines with modern internal combustion. This new constructive method imposes a new in-line engine design in order to better balance it, thus achieving a static balancing and total dynamics of the new type of internal combustion heat engine. The method can also be … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 22 Jul 2019 · 5,823 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 abstractDynamics at Classical DistributionRelly Victoria Virgil PetrescuClassical distribution is the most used in rigid memory mechanisms adapted to four-stroke internal combustion engines such as Otto or diesel, as it was designed by Otto more than 150 years ago, without essential changes from its conception and up today. Since it was not yet possible to introduce the electric car to the industrial scale and today we have … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 26 Apr 2019 · 6,394 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 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 abstractSome Aspects of the Structure of Planar MechanismsRelly Victoria Virgil Petrescu, Raffaella Aversa, Bilal Akash et al.The machine is a technical system made up of distinct kinematic component parts (called kinematic elements) which, following the imprinting of movements imposed on an element or elements (considered as leading elements), cause movements to all other kinematic elements in order to execute a useful mechanical thing, or transforming some form of energy into mechanical energy. It follows from the … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 8 Feb 2018 · 8,020 accessesView PDFCite

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 abstractDynamics of Mechanisms with Cams Illustrated in the Classical DistributionRelly Victoria Virgil Petrescu, Raffaella Aversa, Bilal Akash et al.The paper presents an original method to determine the general dynamics of rotating cam and lifting, customized to flat-plate mechanism. First, the dynamic cinematic is presented. Then the Lagrange equation is resolved and with an original dynamic model with a degree of freedom with variable internal damping the dynamic analysis of two models is then made. The mechanisms presented, scientifically … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 5 Jun 2017 · 8,491 accessesView PDFCite
