The MFC database contains information on the entire range of hydrocarbon fuels and its molecular components. Recent Euro 5b/6 legislation introduced a particle number emission limit (6.0 x 10E11 particles per kilometer) in addition to the mass-based limits for diesel engines. The california Air resources Board is also reportedly considering adding a solidparticle number limit to the upcoming LEV III standards in California. LEV III harmonization with forthcoming Tier 3 regulations is said to be likely. Achieving such specific emissions limits require highly accurate prediction methods, Meeks said, adding that such results were “impossible to do through experimentation, whereas earlier computer modeling of fuel combustion couldn’t even predict the trends of the particle sizes” as related factors were modified.

Biggest modeling challenge

“Soot formation in reaction flows was always the hardest issue in combustion chemistry to predict,” said Chitral Naik, Team Leader and Senior Development Engineer at Reaction Design. “It’s the field’s grand challenge.” In 2005, Meeks recalled, the people at the automakers doing research on advanced engine technology and those at the energy companies working to optimize the combustion and emissions performance of fuels were faced with a di-
