摘　　要：基于摩托车上广泛采用的磁电机CDI(电容放电式)点火系统,针对现有磁电机CDI点火电路的火花放电持续时间短,电容放电能量低等缺点,结合多电容能量叠加点火系统可以提高点火能量,延长火花放电时间的优点,设计了一种磁电机双电容能量叠加点火电路,并在MATLAB中进行了仿真研究。In order to improve the shorter duration characteristic of the spark discharging and the lower energy characteristic of capacitor discharges in the existing magneto capacitor discharge ignition circuit, based on the analysis of the magneto CDI ignition circuit widely used on motorcycles and in consideration of the advantages that multiple capacitor discharges can extend the spark duration and improve ignition energy, this paper designs a magneto dual capacitors energy superposed ignition circuit, corresponding simulation researches are also carried out.
