Exergy Analysis of SI Engines
(International Journal of Exergy (Inderscience Publishers), 2008)
In this study, exergy (availability) analysis of a Spark Ignition (SI) engine has been performed theoretically during compression, combustion and expansion processes of the engine cycle. For this purpose, a thermodynamic-based ...
Investigation of the Effect of Dual Ignition on the Exhaust Emissions of an SI Engine Operating on Different Conditions by Using Quasi-dimensional Thermodynamic Cycle Model
(Strojarstvo (Croatian Union of Mechanical Engineers and Naval Architects), 2009)
In the presented study, the effects of using dual-spark plug and variation of the spark plug location on the exhaust emissions of an SI engine operating in different conditions were investigated theoretically. A quasi-dimensional ...
Comparison of Mechanical Properties Obtained for Armor Steels: Conventional Methods vs. Nanoindentation
(ASTM International, 2023)
The mechanical properties of three armor steels, namely Ramor 500, Ramor 550, and Armox Advance, were acquired by nanoindentation and conventional methods, and then the results were compared. To this goal, samples were ...
Kapalı Kare Ortamlarda Periyodik Olarak Değişen Sıcaklığa Sahip Duvara Konulan Engelin Doğal Taşınım ile Isı Transferi Üzerine Etkilerinin Sayısal İncelenmesi
(6th International Advanced Technologies Symposium, 2011-05-16)
Natural convection heat transfer in square enclosures having a horizontally positioned obstacle on one of the vertical wall is numerically investigated. The obstacle included wall has periodically varying temperature profile ...
Mathematical analysis of spark ignition engine via the combination of the first and second laws of thermodynamics
(Proceedings of Royal Society A-Mathematical Physical & Engineering Sciences (Royal Society Publishing), 2008)
This study aims at the theoretical exergetic evaluation of spark ignition engine operation. For this purpose, a two-zone quasi-dimensional cycle model was installed, not considering the complex calculation of fluid motions. ...

Nat u ral con vec tion heat trans fer in a par tially di vided trap e zoidal en clo sure is stud ied nu mer i cally us ing the con trol vol ume method. Sum mer and win ter con di - tions are sep a rately ex am ined by im ...
Preparation and characterization of electroless Ni–B/nano-SiO2, Al2O3, TiO2 and CuO composite coatings
(2015-06-18)
Ni–B/SiO2, Al2O3, TiO2 and CuO composite coatings were successfully obtained by the electroless plating technique. Dispersible SiO2, Al2O3, TiO2 and CuO nanoparticles were co-deposited with electroless Ni–B coating onto ...
Effect of Working Conditions on the Lubricated Wear Behavior of Zn-40Al-2Cu-2Si Alloy in the As- Cast and T6 Heat-Treated States
(American Society of Mechanical Engineers (ASME), 2022)
In order to determine the effect of working conditions on the lubricated wear behavior of Zn-40Al-2Cu-2Si alloy in the as-cast and T6 heat-treated states, its tribological properties were studied at different oil flowrates, ...
Effect of Plastic Deformation on the Mechanical Properties of Dual-Phase Steels Using Nanoindentation
(Springer, 2023)
The mechanical properties of two advanced high-strength steels (AHSS), DP 1000 and DP 1200 dual-phase (DP) grades, under deformed and undeformed conditions, were investigated using nanoindentation, and the results were ...
High-cycle fatigue and tensile strength of AZ91 Mg alloy with MAO-epoxy duplex coating
(Institute of Materials and Machine Mechanics, 2023)
In this study, an epoxy layer was formed by the immersion process, on the oxide layer grown by the micro-arc oxidation (MAO) treatment of the AZ91 magnesium alloy, using the thin film sealing technology, and its effect on ...
