Comparison of Emissions and Fuel Economy Characteristics of Conventional, Additized, and Substantially Synthetic Diesel Fuels in a Heavy-Duty Diesel Engine 2002-01-1702

This study compared four different candidate fuels which were prepared by blending different components with a typical No. 2 diesel. Two fuels were blended with a synthetic diesel prepared from natural gas condensate, and all candidate fuels were splash blended with a proprietary additive package from International Fuel Technology Inc. (IFT). These fuels were then compared to the No. 2 diesel and to a California Air Resources Board (CARB) equivalent diesel fuel. The comparisons included fuel properties such as sulfur content, aromatics, cetane, lubricity, distillation; emissions; and fuel consumption. Emission testing was conducted on a 1991 Detroit Diesel Series 60. The Environmental Protection Agency (EPA) transient cycle was utilized for emissions, fuel characterization was performed according to ASTM standards, and fuel consumption was calculated by the carbon balance method. Results showed that lubricity, cetane, emissions, and fuel consumption were improved with the candidate fuels when compared to a typical No. 2 diesel.
