Summary:

AbstractThe 50% and 90% distillation temperature (T50 and T90), aromatics, olefins and sulfur content are regulated in California Phase2 Reformulated Gasoline. The effects of these properties on the exhaust emissions were investigated.Twelve test fuels with little interaction between T50, T90, aromatics and olefins were prepared. Exhaust emissions were measured using a TLEV according to 1975 Federal Test Procedure (75 FTP).T50 had a large effect on exhaust HC emissions. T90 also affected HC emissions. Both increasing and decreasing T50, T90 showed increasing exhaust HC emissions. These results suggest that an optimum range of T50 and T90 exist for lowering exhaust HC emissions.The effects of sulfur on exhaust emissions were also investigated. A Pt/Rh type catalyst (production type) and a Pd type catalyst (prototype) were prepared. These catalysts were put on a 94MY TLEV. Increase of sulfur lead to increase of the exhaust emissions with both catalysts. The effects of sulfur on mileage accumulated emissions also were investigated
