Outline of Final Research Achievements

Effects of hydrocarbon structures on auto-ignition characteristics were investigated. The secondary carbon atoms in straight chain(C2), the length of straight chain in the molecules(Cd), the carbon atoms in naphthenes(Cn), the secondary carbon atoms in the side chain of the naphthene ring(C2n), and the carbon atoms in aromatics (Cb) are the parameter variables of the hydrocarbon structure. An HCCI (homogeneous charge compression ignition) engine was operated with various low temperature heat release conditions, and the auto-ignition characteristics of hydrocarbons were investigated. The ignitability trend differences of the naphthenes in the conventional HCCI and SI knocking conditions are one reason why the HCCI ignitability can not be expressed accurately by the octane numbers. From the Livengood-Wu analysis, it was obvious that the most effective operational parameter variable was the engine speed.
