The integral characteristics of burning of stoichiometric and lean hydrogenous mixtures in a cylindrical chamber at initial pressures of 0.024 to 1 MPa have been investigated. The propagation of the flame has been visualized and the distributions of its velocity and the running parameters of burning have been obtained. It has been shown that in synthesis-gas-based mixtures, the flame front has a "cellular structure;" its characteristic dimension grows with propagation of the flame. A method for determining the shape factor, which makes it possible to explain certain experimental regularities of burning, has been proposed. The results of the work can be used in selecting the parameters of mixtures and combustion chambers of heat engines operating on modified fuels.
