The correlation between the autoignition characteristics of n-butane/di-methyl ether/air mixtures and the knock intensity in a rapid compression and expansion machine was studied. The propagation velocity was obtained from the images of propagating flames at the moment of autoignition by a high-speed camera. The dimensionless parameters, ... and ..., were used in the investigation, which are based on the theories of Zeldovich and Bradley. To obtain these dimensionless parameters, the numerical calculation using CHEMKIN-PRO with AramcoMech1.3 was carried out. The smaller gradient of autoignition delay time for n-butane with the higher amounts of di-methyl ether addition caused the higher flame propagation velocity and the resultant higher knock intensity, while significant differences of excitation times for autoignition heat release could not be seen. As a result, the gradient of autoignition delay time was concluded to have a strong influence on the knock intensities. (ProQuest: ... denotes formulae/symbols omitted.)
