“…Only few measured RON/MON available for alkyl cycloalkanes [56], thus it is not possible to summarize the regularity due to the lack of experimental data and the generation of predicted data is required. Ignition quality studies on cyclic hydrocarbons are also presented as critical compression ratio [62] and aniline equivalent [67].…”

“…Numerous efforts have been performed to advance fundamental understanding of the relationship between octane number and fuel chemistry. The earliest attempt in understanding the effect of molecular structure on fuel's antiknock quality was done by Lovell and co-workers [11,12,13,14,15], wherein they studied the knock characteristics of 27 paraffins [11], 25 aliphatic olefins [11], 69 naphthenes [13] and 22 aromatics [14] using aniline as a standard for rating fuels. They were able to establish a consistent connection with molecular structure and knock propensity.…”

“…Although much research has been carried out in the general field of combustion this has usually involved fired engines (e.g, Rassweiler and Withrow, 1933;Lovell et al, 1934;Rifkin et aI., 1952;Cornelius and Caplan, 1952;Rifkin, 1954 andBowditch andStebar, 1958), or conventional laboratory work using small static unstirred reactors (e.g. Bone and Hill, 1930;Townend et al, 1934;Prettre, 1949;Johnson et al, 1953 andWestbrook et al, 1988) or continuous flow systems (Cullis and Hinshelwood, 1949;Malmberg and Babbitt, 1955;Salooja, 1960;Cartlidge and Tipper, 1961;Sahetchian et aI., 1979 andGokalp et al, 1981).…”

A motored, unfired CFR engine was red with a rich heptane/air mixture. The jacket temperature was maintained at lOOcC with a few experiments at Oee. The ·exhaust vapours were totally condensed by a novel exhaust recovery system. After completely removing cylinder deposits. no reaction products were round at compression ratios up to 14: I. At a compression ratio or 16: I the charge autoignited/detonated. Subsequently, reaction products were round at a compression ratio or 6: I and thereafter in increasing quantities up to 14.6: I, the reproducible threshold of autoignition. This entire sequence or experiments was reproduced four times. Samples of the condensate were concentrated by vacuum distillation and subjected to qualitative and quantitative analyses. A very limited range of peroxides and carbonyls were formed in very low concentrations in all experiments where autoignition did not occur. These were identified and their rates of formation calculated. Some thermodynamic inferences were drawn as to their heats of formation. The maximum compression temperatures were calculated. At compression ratios below 16: I, it was concluded that the preflame reaction was initiated on the surface or the combustion chamber, after it had been subjected to autoignitions/detonations,
