Influence the velocity propagation and flame ionization on concentrations unburned hydrocarbons in the CNG engine

Experimentally determined the relationship flame propagation velocity and ionization with concentration of unburned hydrocarbons in the gas combustion engine with spark ignition. The expediency of the use of the parameter ( K ), which reflects the ratio of the normal and turbulent flame propagation velocity, to evaluate the effect of the relative velocity changes in the allocation of the combustion of unburned hydrocarbons engine.
