COMBUSTION OF RENEWABLE OILS AND FATS

摘要

A method of combusting a renewable oil or fat comprises injecting the oil or fat into a combustion cylinder of a heterogeneous-charge compression-ignition engine and supplying to the cylinder inlet port combustion air or working fluid at a temperature substantially above ambient for substantially the entire time that the engine is running. Other aspects of the invention provide a compression ignition engine for use in the method, and a method of using the engine to combust renewable oils or fats.
