The effect of mixture component makes a nelay time and a long total combustion period $ au_{p;max}$. The flame propagation delay $ au_{df}$ was determined by the record of current ion. The pressure release delay $ au_{dp}$ and $ au_{p;max}$ were determined by the indicated pressure diagram in constant volume of the combustion chamber. The results are as follows: 1) The ignition delay $ au_t$ time takes the minimum value around $Phi=1.15$. 2) $ au_{df}$ and $ au_t$ time increased according to the increases of the concentrated dilution gases, because the adiabatic flame temperature decreased due to the increases of the heat capacity. But dilution gases have little effect on flame nucleus formation delay 3) The relation between $ au_t$ time and reciprocal laminar burning velocity is almost linear. 4) The increase of the propagation length is accompanied with increased ratio of the $ au_{df},; au_{dp},; au_{t},; au_{p;max}$.
