Research ArticleOpen accessIn the abstractSomething about the Balancing of Thermal MotorsRaffaella Aversa, Relly Victoria V. Petrescu, Bilal Akash et al.Internal combustion engines in line (regardless of whether the work in four-stroke engines and two-stroke engines Otto cycle engines, diesel and Lenoir) are, in general, the most used. Their problem of balancing is extremely important for their operation is correct. There are two possible types of balancing: Static and dynamic balance. The total static to make sure that the sum … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 15 Mar 2017 · 7,785 accessesView PDFCite
Research ArticleOpen accessIn the abstractStructural Dynamics of the Distribution Mechanism with Rocking Tappet with RollFlorian Ion T. Petrescu, John Kaiser Calautit, Dragan MarinkovicIn this study, the authors present a new method to dynamically synthesize a mechanism with rotary cam and rotated tappet with roll, used with priority at the distribution mechanisms from the heat engines with internal combustion. This type of distribution can improve the changes of gases and may decrease significantly the level of vibration, noises and emissions. As long as … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 28 Oct 2015 · 9,290 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeometrical Synthesis of the Distribution MechanismsFlorian Ion T. PetrescuIn this study the author presents shortly some few original trigonometric methods to make the synthesis of some main distribution mechanisms. One presents four main modules of distribution mechanisms, with rotary cam and translated or rotated tappet plane or with roll, used with priority at the distribution mechanisms from the heat engines with internal combustion. These types of distribution mechanisms … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 1 · 13 Apr 2015 · 8,858 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Fuel Properties on Exhaust Emissions during Warm-Up ProcessRosli Abu Bakar, Beny CahyonoProblem statement: Increasing air pollutions the big problem form internal combustion engines. Several attempts have been done to get a cleaner combustion process, one of which is the use of fuel ethanol in gasoline engines. Approach: The addition of ethanol in fuel will be change fuel properties. Results: To know the effect of fuel properties on engine performance and emissions … …Energy Research Journal, Vol. 2, Issue 1 · 23 Jan 2012 · 7,278 accessesView PDFCite
Research ArticleOpen accessIn the abstractThermal Efficiency of a Combined Turbocharger Set with Gasoline EngineJarut KunanoppadonProblem statement: The technology of turbocharger has been used with internal combustion engines since 1905 to increase intake air pressure prior to putting it into the cylinders to increase thermal efficiency of the engine. Based on previous researches and uses of turbochargers, the pattern of turbocharger installation remains the same, either in series or in parallel. Therefore, this research aims … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 8,136 accessesView PDFCite
Research ArticleOpen accessIn the abstractNumerical Study on the Performance Characteristics of Hydrogen Fueled Port Injection Internal Combustion EngineRosli A. Bakar, Mohammed K. Mohammed, M. M. RahmanThis study was focused on the engine performance of single cylinder hydrogen fueled port injection internal combustion engine. GT-Power was utilized to develop the model for port injection engine. One dimensional gas dynamics was represented the flow and heat transfer in the components of the engine model. The governing equations were introduced first, followed by the performance parameters and model … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 8,140 accessesView PDFCite

Research ArticleOpen accessAll words, across the recordPresentation of the Mechanism in the CrossFlorian Ion Tiberiu Petrescu, Taher M. Abu-Lebdeh, Antonio ApicellaThe cross-machine has frequent uses in mechanical assemblies, automation, robotics and mechanisms with various uses. In the present paper we want to present this type of mechanism with its main, geometric, cinematic, strengths and propose its study in its possible use as an internal combustion engine. In this novelty, the mechanism will have two types of operation, one when operated … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 26 May 2018 · 8,064 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordStudy of an Oscillating Sliding MechanismFlorian Ion Tiberiu Petrescu, Taher M. Abu-Lebdeh, Antonio ApicellaA mechanism with an oscillating slider is a mechanism quite often used in the technique. It has some advantages over other similar mechanisms being able to work with accelerations and reduced forces under the same conditions with another similar mechanism. For example, an internal combustion engine could be built more efficiently with this mechanism, resulting in a motor that would … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 26 May 2018 · 8,005 accessesView PDFCite
