Experimental and numerical investigation on the jet characteristics of spark ignition direct injection gaseous injector

Combustion process and emissions of a heavy-duty engine fueled with directly injected natural gas and pilot diesel

“…His results showed that increasing pressure ratio and injection duration could cause increases in jet penetration and jet diffusion rate. Both experimental and numerical investigations were performed by Chitsaz et al [22] to explore the behavior of gaseous fuel injection and it was concluded that tip penetration could benefit from higher pressure ratios and larger nozzle diameters. To investigate the detailed jet flow structures, Yu et al [23] adopted planar laser-induced fluorescence to study the mixture formation in direct injection gas engine.…”

Numerical and experimental study of gaseous fuel injection for CNG direct injection

“…Many researchers have investigated ways to simulate gas fuel injection [5][6][7][8][9][10]. Chitsaz et al [11] reported an experimental and numerical study on the jet structure of a gaseous fuel injector in a spark ignition direct injection engine using the Schlieren technique and a numerical procedure. They found that a higher pressure ratio and larger exit nozzle diameter led to more tip penetration except in the initial stages of jet development.…”

Experimental and theoretical investigation on spray characteristics of bio-ethanol blends using a direct injection system

“…Several research works have already paid attention to the spray properties of bio-fuels and their key roles on the mixture formation, combustion, and environmental issues [22][23][24][25][26][27][28][29]. In the present work, spray pattern and mixture formation of bio-ethanol and its blends with conventional gasoline have been examined, and in uences of a number of parameters on spray characteristics of several blends have been performed.…”
