At the 3rd International Colloquium - Fuels 2001 -held in Esslingen, Germany on 17-18 January 2001, Dr. M. Gairing of DaimlerChrysler AG, Stuttgart, outlined ideas for a new version.
While the WWFC was being drawn up, discussions were already under way with both Japan and the USA, in parallel, for a new version with sulfur levels of <10ppm for both gasoline and diesel fuels. He said that it was his belief that the future was "lead-free and sulfur-free".
There is a wide range of fuel standards around the world, offering varying levels of quality. He said that we need to develop a world-wide quality for fuels because fuel is an important engineering element for all vehicles.
The discussions need to involve customers, the oil industry, the automotive industry and governments. It is his belief that emissions standards cannot be achieved without adequate fuel standards. The most important single parameter today is sulfur but all other parameters must be respected.
Dr Gairing then went on to highlight the current differences between the existing standards for diesel (EN 590) and gasoline (EN228) and the new proposals for WWFC Category 3 / 4. Dr Gairing felt that a gap of 5 points in the current Cetane No/Cetane index is too great as this has a significant influence on the noise of a diesel engine. Similarly of the density is too high then emissions will rise and if it is too low, then the power will drop. He felt that the only way to guarantee new developments is for fuels to go sulfur free.
