...Seyfi Polat; Hamit Solmaz; Ahmet Uyumaz; Alper Calam; Emre Yılmaz; H. Serdar Yucesu In this study, the effects of negative valve overlap (NVO) on homogenous charge compression ignition (HCCI) combustion and engine performance were experimentally investigated. A four stroke, single cylinder, port...

Journal: Journal of Engineering for Gas Turbines and Power
Article Type: Research-Article
J. Eng. Gas Turbines Power. July 2019, 141(7): 071023.
Paper No: GTP-19-1133

Published Online: April 22, 2019
... research was performed on a single cylinder engine equipped with a fully flexible valve train mechanism and direct gasoline injection. The HCCI combustion mode with exhaust gas trapping was realized using negative valve overlap (NVO) and fuel reforming, achieved via the injection of a portion of fuel...
