A method for eliminating or substantially reducing unstable combustion conditions within a combustion chamber. By adding hydrogen to the inlet fuel mixture, the method provides a means for altering the overall combustion (reaction) rate and the resulting characteristic reaction time that, in turn, will eliminate or substantially reduce undesirable pressure oscillations. Moreover, the invention provides a low cost and easily installed method for active control of pressure oscillations within a combustion chamber
