1-D Modelling Comparative Study to Evaluate Performance and Emissions of a Spark Ignition Engine Fuelled with Gasoline and LNG
Yontar, Ahmet Alper; Dogu, Yahya (E D P Sciences, 2016)In this study, a spark-ignition engine fuelled with gasoline and LNG was modelled in 1-D at wide open throttle by using Ricardo-Wave software. Different engine speeds ranging from 1500rpm to 4500rpm with an increment of ... -
Buji ateşlemeli motorda saf ve karışımlı alternatif yakıtların motor performansına ve emisyonlarına etkilerinin sayısal ve deneysel incelemesi
Yontar, Ahmet Alper (Kırıkkale Üniversitesi, 2016)Bu doktora tez çalışmasında buji ateşlemeli bir motorda saf ve karışımlı yakıt kullanımının motor performansı ve egzoz emisyonlarına etkileri sayısal ve deneysel olarak incelenmiştir. Saf yakıt olarak benzin, CNG, LPG ve ... -
Effects of equivalence ratio and CNG addition on engine performance and emissions in a dual sequential ignition engine
Yontar, Ahmet Alper; Doğu, 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 ... -
