Using absorption spectroscopy, simultaneous measurements were made of the behavior of the OH (characteristic spectrum of 306.4 nm), CH (431.5 nm) and C2(516.5 nm) radicals in the end-gas region and center of the combustion chamber of a spark-ignition engine during preflame reactions with four types of fuel having different octane numbers. The results of this research show that the behavior of the OH, CH and C2 radicals in preflame reactions differed significantly in both the center and end-gas region of the combustion chamber depending on the octane number of the fuel and also between normal and knocking combustion conditions.
