Homogeneous Charge Compression Ignition (HCCI) is an advanced combustion process that exhibits sensitivity to differing fuel properties. Often research conducted on HCCI uses research grade fuels to study combustion. The goal of this paper is to investigate the effects of partially refined and transportation fuels on HCCI combustion. Tested fuels include partially refined gasoline and Jet B. An experimental comparison of the fuels is conducted on a single cylinder test engine operating at a compression ratio of 12:1. Each fuel is tested in HCCI operation and compared to the same tests done with a primary reference fuel blend of comparable octane number. The resulting data is useful in characterizing the differences between the transportation grade fuels and the primary reference fuels.
