Knock intensity of n-butanol shows more sensitivity to spark timing. Probability distribution can be applied to evaluate variation of knock intensity. n-Butanol exhibits lower knock intensity growth rate as intake pressure increase. Effective knock suppression EGR rate for n-butanol was quantified.
