San Diego, California – Volkswagen has become the first German automaker to join the Model Fuels Consortium II (MFC-II), which focuses on designing cleaner-burning, more efficient engines and fuels.

Other automakers in the Consortium are Mazda, PSA Peugeot Citroën, Suzuki, and Toyota.

The initial phase of the Model Fuels Consortium was launched four years ago by software supplier Reaction Design, which specializes in clean technology chemistry. Volkswagen said it is particularly interested in the Consortium’s focus on modelling the combustion of both traditional fuels and potential next-generation blends with accurate chemistry.

“Increasing fuel efficiency and reducing emissions have become the driving forces in the automobile industry,” said Axel Winkler of Volkswagen Group Powertrain Research. “The accomplishments of the first phase of the MFC caused us to broaden our tool landscape and strategies we were putting in place for research. At first, we were skeptical that Reaction Design’s MFC-II would provide a meaningful completion to our technical road map, but once we had the opportunity to evaluate extensively the comprehensive solutions being developed by the group, it was clear to us that MFC-II was worth the investment. We view our membership as a valuable resource in our ongoing efforts to develop highly efficient and innovative engine designs.”

The Consortium’s three main goals are to develop detail chemical mechanisms for new fuel components that allow representation of a broader set of fuels and more accurate prediction of fuel emissions characteristics; to develop a science-based, fundamental model of soot-particle growth from gas-phase precursors; and expanded capability to connect detailed kinetics with multi-dimensional engine simulations.

Chemical reaction mechanisms for two new cycloparaffins were completed as part of this year’s MFC-II work. These represent important additions, as there are significant quantities of cycloparaffins in conventional fuels, and even higher quantities in fuels under development, such as those derived from oil sands; representing these components in model fuels is important to predicting soot formation with different fuel blends.
