Abstract: The paper evaluates and discusses the combustion characteristics of electrolytically produced stoichiometric hydrogen-oxygen mixtures under constant volume adiabatic conditions. The results will be used in the preliminary design of a combustion chamber of a hydrogen-oxygen fuelled engine. Maximum combustion pressures are investigated and compared to theoretical predictions based on the first law of thermodynamics, ideal gas laws and adiabatic flame temperature. High temperature dissociation is not taken into account. Experimental results are within 10% of theoretical predictions. Ignition delay time and rate of pressure rise are also investigated and discussed. The ignition delay time is a function of the initial mixture pressure and decreases exponentially from a maximum value of 6.6 ms towards zero as the initial pressure of the mixture is increased.
