Effects of equivalence ratio and CNG addition on engine performance and emissions in a dual sequential ignition engine
Yontar, Ahmet Alper; Dogu, Yahya (SAGE PUBLICATIONS LTD, 2020)Compared to widening usage of CNG in commercial gasoline engines, insufficient but increasing number of studies have appeared in the open literature during last decades, while engine characteristics need to be quantified ... -
Experimental investigation of effects of single and mixed alternative fuels (gasoline, CNG, LPG, acetone, naphthalene, and boron derivatives) on a commercial i-DSI engine
Dogu, Yahya; Yontar, Ahmet Alper; Kantaroglu, Emrah (TAYLOR & FRANCIS INC, 2020)A commercial i-DSI (Intelligent-Dual Sequential Ignition) engine is tested to investigate performance and emissions for single fuels and alternative fuels mixed into gasoline. The novelty of the study is the first time ... -
Investigation of ignition advance effects for CNG usage in a sequential dual ignition gasoline engine by using in-cylinder combustion cfd analysis
Yontar, Ahmet Alper; Dogu, Yahya (Gazi Univ, Fac Engineering Architecture, 2019)In this study; for a sequential dual ignition gasoline engine, the effects of ignition advance on engine characteristics and in-cylinder flame propagation have been numerically investigated for CNG usage with an in-cylinder ... -
Investigation of the effects of gasoline and CNG fuels on a dual sequential ignition engine at low and high load conditions
Yontar, Ahmet Alper; Dogu, Yahya (Elsevier Sci Ltd, 2018)In this study, a dual sequential spark ignition engine is separately tested either with gasoline or CNG at low and high loads. In addition, numerical engine analyses are performed by constructing a 1-D engine model in ... -
