... ) showcases the full model. The impact of model parameters on calculated NOx emissions is depicted in the staged bar plots, consisting of flame front NOx (indicated by dots) and postflame NOx (indicated by hatch lines). Plot (a) and (b) illustrate calculated emissions for constant parameters set to unity...

... balanced. Although higher P IVC can effectively reduce NO x emissions, the degree of improvement is still limited. The minimum NOx emissions are still higher than the European VI emission regulations (0.4 g/kW h). When SOI is –35 deg CA ATDC, the emissions of NO x , HC, and CO are very high. Fig...

... increase of the NO x emissions with the decreasing degree of premixing observed in the experiments, however, quantitative predictions would have required a postprocessing of the data from the LIF mixing study with a higher spatial resolution than available. NOx emission mixing LIF PIV syngas...
