This article reports on the technical trials organised by the Brewery Transport Advisory Committee (BTAC) and the Institute of Road Transport Engineers (IRTE), held in June 1999 at the proving ground of the Motor Industry Research Association (MIRA) near Nuneaton, England. A large part of the trials focused on the effect of ultra-low-sulphur diesel (ULSD) on lorry fuel consumption. Although their results gave no clear verdict, they will be of great interest to many transport engineers. Parcelforce Worldwide wanted to compare the performance of two parcel-delivery vehicles switched between 'normal' (high-sulphur) diesel and ULSD: a 7.5t Daf and a 6.4t Iveco/Papworth. Tests were also conducted on a 7.5t Coca-Cola Schweppes Beverages lorry. For these vehicles, fuel type had only a small and inconsistent effect of fuel economy. Lorry fuel consumption was also tested for a Three Valleys 75CF fitted with a standard Daf exhaust or with an exhaust particulate trap from Wasey exhausts, using Englehard DPX catalytic filters. In the test with the trap, fuel consumption increased by about 8%, but this result, like the others, was inconclusive, due to the many variables present. Perhaps the effect is smaller than the experimental errors, or perhaps various types of engines and fuel injection systems respond to ULSD in various ways.
