... recently been shown that spark plugs with a nanostructured central electrode, treated using pulsed laser irradiation and effectively increasing the surface area, extend the lean flammability limit (LFL) of methane/air mixtures in a constant volume combustion chamber (CVCC). In this study, the effect...

... with methane (CH 4 ) as the gaseous fuel. Crank angle resolved emissions of NO x and PM are also presented. The model results give good confidence in the current approach for the description of premixed combustion following the ignition of the pilot. phenomenological dual fuel combustion modelling...
