DIESEL ENGINE EFFICIENCY IMPROVEMENT

摘要

The invention provides a method of operating a diesel engine under oxygen-limited conditions such that the efficiency of the engine is at least 1% improved over the engine efficiency obtained when using a conventional crude-derived diesel fuel, said method including the combustion of a distillate fuel having a density of below 0.800 g.cm-3 in the engine. The invention extends to the use of a distillate fuel with a density less than 0.800 g.cm-3 (at 20°C) for achieving increased engine efficiency when operating a diesel engine under oxygen-limited conditions, said use including combusting said fuel such that the efficiency of the engine is at least 1% improved over the engine efficiency obtained when using a conventional crude-derived diesel fuel.
