An Experimental Approach for Engine Mapping

Taymaz, İmdat (2009)
Sliding Friction and Wear Behavior of Pack-Boronized AISI 1050, 4140, and 8620 Steels

Soydan, Yavuz; Köksal, Sakıp; Demirer, Ahmet; Veli Celik (TAYLOR & FRANCIS INC, 2008)

This paper describes the dry sliding friction and wear performance of boronized AISI 1050, 4140, and 8620 steels with the Fe(2)B phase coating on the surface. The studies were carried out using a pin-on-disc arrangement. ...
Welding time effect on mechanical properties of automotive sheets in electrical resistance spot welding

İlhan, Erdinç; Aslanlar, Salim; Oğur, Ahmet; Özsaraç, Uğur (ELSEVIER SCI LTD, 2008)

In this study, the effects of welding time on the tensile-peel strength and tensile-shear strength of welding joints in electrical resistance spot welding of chromate micro-alloyed steel sheets having 1.2 mm thicknesses ...
Prediction of convection heat transfer in converging-diverging tube for laminar air flowing using back-propagation neural network

Taymaz, İmdat; İslamoğlu, Yaşar (PERGAMON-ELSEVIER SCIENCE LTD, 2009)

The ability of an artificial neural network (ANN) model for heat transfer analysis in a converging-diverging tube is studied. Back propagation learning algorithm, the most common method for ANNs, was used in training and ...
The Comparison of Two-Stage and One-Stage Engine Mapping

Taymaz, İmdat (2008)
THE COMPARİSON OF TWO-STAGE AND ONE-STAGE ENGİNE MAPPİNG

Kozan, Recep (2008)
Effect of ion nitriding on fatigue behaviour of AISI 4140 steel

Genel, Kenan (ELSEVIER SCIENCE SA, 2000)

Ion nitriding has become a popular thermo-chemical surface treatment, which is being used to develop fatigue and wear characteristics of steels. Besides the increased strength, the formation of high compressive residual ...
Evaluation of Tribological behavior of PEEK and glass fibre reinforced PEEK Composite under dry sliding and water lubricated conditions

Sümer, Mensur; Ünal, Hüseyin; Mimaroğlu, Abdullah (2008)
TWO-STAGE ENGİNE MAPPİNG MODEL OF A DİESEL ENGİNE

Kozan, Recep (2008)
Sheet metal forming analyses with an emphasis on the springback deformation

Fırat, Mehmet (ELSEVIER SCIENCE SA, 2008)

An accurate modeling of the sheet metal deformations including the springback is one of the key factors in the efficient utilization of FE process simulation in the industrial setting. In this paper, a rate-independent ...
Experimental study of NOx emissions and injection timing of a low heat rejection diesel engine

Büyükkaya, Ekrem; Cerit, Muhammet (ELSEVIER FRANCE-EDITIONS SCIENTIFIQUES MEDICALES ELSEVIER, 2008)

In this study, an experimental study of the effects of injection timing on nitrogen oxide (NOx) emissions of a low heat rejection (LHR) turbocharged direct injection diesel engine was conducted. The injection timing and ...
First and second law analysis of low heat rejection diesel engine

Yaşar, Halit (ELSEVIER SCI LTD, 2008)

In this study, a comparative first and second law analysis of a turbocharged diesel engine was performed. The main aim was to investigate the impact of thermal insulation on energy, and exergy balances of the engine. For ...
Double-Wiebe function: An approach for single-zone HCCI engine modeling

Yaşar, Halit; Soyhan, Hakan Serhad (PERGAMON-ELSEVIER SCIENCE LTD, 2008)

Single-zone Wiebe-function HCCI combustion models tend to over-predict the peak cylinder pressure. The over-prediction arises because it is not possible for the standard Wiebe function to fully match both the slower ...
Tribological properties of MgZrO3 coatings deposited by plasma spraying

Uçar, Vahdet; Demirkıran, Ayşe Şükran (REDAKCIA KOVOVE MATERIALY, 2008)

Because of thermal barrier properties, ceramic-based coatings are widely used for the design of components at high temperature applications. Therefore, 304 L stainless steel substrates were coated with MgZrO3 coatings using ...
