Mathematical Modeling of Combustion Process of synthesis gas in the cylinder ICE

B.G. Timoshevsky, M.R. Tkach, A.S. Mitrofanov

The mathematical model of synthesis gas combustion of in piston engines with spark ignition is presented. A distinctive feature of the model is the account of the propagation velocity of the flame front in the cylinder depending on the composition of synthesis gas. In detail describes how to determine the area of the flame front, as well as the volume of burnt synthesis-gas, depending on the geometric characteristics of the combustion chamber and the speed of combustion synthesis-gas. The adequacy of this model by comparing of mathematical modeling results and available experimental data is established. The discrepancy between these results does not exceed 8%, which is quite acceptable for modeling of ICE operation processes.

Key words: synthesis gas, alternative fuel, the flame front, the rate of combustion, steam-conversion, the parameters of the working process.
