A hydrocarbon fuel has its inherent ignition quality based on the chemical structure, and, for the family of normal paraffins, the characteristic value may be supposed to be in proportion to the carbon number. The project of the present study was to verify the relationship in such a way that the variations of ignition lag in CFR Diesel engine were measured when several kinds of high-carbon normal paraffins were added to or solved in a base fuel by varied amount and the rates of change in ignition lag were used for evaluation. Kogazin I (nearly Octane) was adopted as base fuel, and two liquid higher paraffins (C_<16>, C_<17>) and three solids (C_<19>, C_<21・5>, C_<31>) were examined. It was found that the inherent ignition quality increases with the carbon number irrespective of whether liquid or solid paraffins. The characteristic values obtained for the above paraffins except Cetane are 104,115,136 and 202 in the order in terms of cetane value.
