...) engines. For high energy substitution (>70%) conditions, NO x emissions are a function of the premixed gas lambda ( λ ng ) and contain a local minimum, with NO x increasing as lambda is either leaned or richened beyond the local minimum which occurs from approximately λ ng = 1.7 – 1.85...

... allows for a continuum of in-cylinder blend levels from pure gasoline to pure NG operation. The huge benefit of gasoline is its availability and energy density, whereas NG allows efficient operation at high load due to improved combustion phasing enabled by its higher knock resistance. Furthermore, using...
