A method of calculating a volume of combustion products when a flame spreads in the closed cylindrical chamber is developed, assuming that the front is spherical for two positions of an ignition source: at the end (central ignition) and cylindrical (side ignition) walls of the combustion chamber. Universal formulas for the volume of combustion products are obtained with regard to the changes in the flame front shape and the combustion chamber geometry allowing a mixture burning rate and a heat release characteristic to be investigated. Based on the analysis of the experimental data, the dependences of the change in the volume of combustion products on time and flame front radius are obtained for fuel-air mixtures with a volume fraction of hydrogen from zero to 14 % at stoichiometry coefficients &#966 = 0.8, 1.
