Abstract	The invention provides enriched fuels and methods that expand the operating envelope of an advanced combustion engine during operation in an advanced combustion mode (e.g. HCCI mode). Enriched fuels and methods of the invention facilitate efficient combustion over a wide range of engine loads, and the need for EGR, VVT, NVO, rebreathing, or multiple fuel injection is either reduced or eliminated.
