Abstract

In order to establish the ignition system for lean burn, the influence of the number of spark plug, spark times and spark intervals on discharge pattern of spark energy, ignitability and combustion characteristics were evaluated. By visualizing the flame propagation with the number of spark plug, heat release was related with flame area, heat loss related with contact wall area by burned gas, combustion duration related with maximum flame travel distance respectively. It showed that, ignitability remarkably increases with the case of MSCDI than with the case of single spark and the lean limit extended fuel/air equivalence ratio by 0.1, the increase of magnitude and lasting time of capacity component and inductance component was multi spark discharge in a row.
