... representing natural gas, Reynolds-averaged Navier–Stokes (RANS) k–e turbulence, and the G-equation combustion model were used. The spark-ignition time was assumed to be 719.5 crank angle degree (CAD), which was the start of the diesel injection time. Analysis was carried out at 2300 revolutions per minute...

...David Sebastian Pérez Gordillo; Juan Miguel Mantilla González This article presents the computational optimization of a spark ignition engine fueled with biomass-derived syngas. KIVA 4 is used as simulation platform, where a three-dimensional model is implemented considering the valve system...

... between engine control variables and the ammonia engine performance. The parametric studies conducted by the well-trained machine learning model suggested that the combustion law of heavy-duty ammonia engines was consistent with that of traditional spark ignition engines. Most importantly, the regular...

... spark-ignition (SI) conditions within the framework of CFPH. To this end, four TPRF-bioblendstock surrogates having different compositions but matched RON (=98) and MON (=90), were first generated using a non-linear regression model based on artificial neural network (ANN). Three unconventional...

...Zongyu Yue; K. Dean Edwards; C. Scott Sluders; Sibendu Som Engine knock remains one of the major barriers to further improve the thermal efficiency of spark-ignition (SI) engines. SI engine is usually operated at knock-limited spark advance (KLSA) to achieve possibly maximum efficiency with given...
