Use of a convenient thermodynamic model to study the effects of operating parameters on nitrogen oxides emissions for a liquefied methane fueled spark-ignition engine

With the increasingly restrictive emission regulations, the emission requirements for internal combustion (IC) engines become more stringent, especially the amount of nitrogen oxides (NOx) emissions. In this investigation, a convenient thermodynamic model was employed to study the effects of operating parameters on NOx emissions for a liquefied methane fueled spark-ignition engine. The selected GRI-MECH 3.0 mechanism was verified by the...
