Plasma could increase chemical and heat effect at the same time during the fuel reaction and it is expected to be an effective technical way of ignition assistance. Plasma assisted methane ignition experiment system was built based on shock tube. The methane ignition delay time of autoignition, under continuous discharge and when discharge is cut down was measured. The plasma's effect to shorten methane ignition delay under different diluent gas was analyzed. The plasma emission spectrum measurement system was built and the emission spectrum in discharge unit was measured. The active particle concentration is higher with higher ignition temperature under experimental condition. The methane ignition delay time could be shortened by 30% to 95% by a little discharge power ( < 4 W). The shortening effect of plasma is better when the ignition temperature is lower than 1 000 K or higher than 1 400 K with the diluent gas Ar. The shortening effect of plasma decreases with the increase of ignition temperature with the diluent gas N2.
