Analysis of an innovative combustion chamber with the wall guided fuel injection in a small diesel engine
Temizer, İlker; Öncüoğlu, Öncel; Cihan, Ömer (SAGE Publications Ltd, 2023)This paper has included the effects of different bowl geometries which has the wall guided fuel injection. Bowl geometries, which affect in-cylinder air flows, have a great influence on the change of mixture formation. ... -
Investigation of lubrication and tribological behaviors in a diesel engine with the new designed flow-guided combustion chamber
Temizer, İlker; Cihan, Ömer; Eskici, Bünyamin (Elsevier Ltd, 2024)Changes to the piston bowl geometry directly affect engine performance, exhaust emissions, combustion characteristics and air/fuel mixture formation. In this study, a new combustion chamber (NCC) geometry for a single ... -
Numerical and Experimental Study of Passive Pre-chamber Turbulent Jet Ignition on Wankel Engine
Dillice, Harun; Kutlar, Osman Akın; Taşkıran, Özgür Oğuz; Cihan, Ömer; Arslan, Hikmet; Çalık, Alper; Çetiner, Arda (American Institute of Physics, 2024)This study aims to increase the flame speed in the Wankel engine by using turbulent jet ignition. The Wankel engine suffers from poor exhaust emissions and high fuel consumption due to insufficient combustion speed and the ... -
Prediction of the mean turbulence intensity with a thermodynamic model for CNG and gasoline fuels
Doğan, Hüseyin Emre; Demirci, Abdurrahman; Kutlar, Osman Akın; Arslan, Hikmet; Cihan, Ömer (Elsevier Ltd, 2023)Combustion is the main parameter that affects efficiency and exhaust gas emissions in internal combustion engines. In this study, the burning speed of gasoline and CNG were investigated quantitatively by calculating the ...
