... °C. The numerical results were validated with experimental results for the reliability of this work. The results of this work were compared in terms of cylinder pressure, rate of heat release (ROHR), indicated specific nitrogen oxide (ISNO), indicated specific carbon monoxide (ISCO), ignition delay...

... of ambient density, ambient temperature, oxygen concentration and reaction mechanism on ignition delay, flame lift-off length, and soot formation are analyzed and discussed. The results show that although higher ambient density and temperature reduce the ignition delay and cause the flame stabilization...

... on ignition delay and combustion characteristics for various injector and ambient conditions. Experimental results showed that all gaseous fuels exhibited similar ignition-delay trends: ignition delay ( τ ) increased as ambient temperature ( T i ) decreased. Among these fuels, hydrogen jets exhibited much...
