A numerical study of the combustion of hydrocarbon fuel requires solving a system of differential equations. This describes multistage chain chemical reactions, molecular transfer, momentum transfer, heat and mass due to convection, radiation, turbulence, evaporation of liquid droplets, etc. In this paper we have the experience of numerical simulation of combustion based on a homogeneous model. This model displays a continuous spectrum of combustion modes - from diffusion flame to detonation. Knitted environment in a variety of heat engines. The gas flow is described by the laws of conservation of mass, momentum and energy. To display the motion of particles of a chemically reacting mixture with a different background, a mixed arbitrary Lagrangian - Eulerian method is used. The identification of positive energy surges is realized on the basis of differential process activation analyzers. In this case, energy jumps are adequate to certain levels of activation of chemical transformations. The paper gives examples of the calculation of the working process in a pulsejet engine.
