摘  要：
By analyzing and researching a charging or discharging process of traditional ignition system, an ignition process of engine mixture, as well as special requirements of new type spark ignition engines, a new superposed energy type of ignition system to ignite mixture of spark-ignition engine, which is different from the traditional ones, is put forward in this paper. Meanwhile, the ignition system circuit skeleton diagrams are given too. On the bases of these, the essential compositions, the working principle, and the charging or discharging characteristics were set forth in detail. Furthermore, the experimental researches on this superposed energy type ignition system matching a spark-ignition engine have been done. The test results show that this ignition system is very effective to improve power performance, economic performance and emission characteristics of ignition engines. So it provides a fairly reliable theoretical foundation to develop superposed energy type ignition system deeply.
