use of a fuel composition of a fischer-tropsch-derived fuel, and method for improving the responsiveness of a compression-ignition engine and / or a vehicle that is powered by such an engine

摘要

The use of a Fischer-Tropsch derived fuel in a fuel composition that improves the responsiveness of a compression ignition engine, such as a turbocharged direct injection diesel engine, and/or a vehicle which is powered by such engine, is provided. A method of improving the responsiveness of such an engine and/or vehicle powered by such an engine by replacing in such engine a fuel composition which contains no Fischer-Tropsch derived fuel by a Fischer-Tropsch derived fuel or a fuel composition which contains a Fischer-Tropsch derived fuel is also provided.
