摘　　要：介绍了一种新型的高能点火装置,该装置与电感储能式点火装置相比,其火花的能量大、持续时间长,并具有点火能量和持续时间可控制的功能。在燃用多种燃料的转子发动机上的应用表明,在发动机不同工况下,该装置可以由电子控制单元控制火花的能量和火花的持续时间,并精确地进行匹配,使发动机的动力性能和烟度处于最佳状态。A new type of high energy ignition system is introduced.Compared with the inductive energy storage type ignition unit,this new type of ignition system has its higher ignition energy and longer duration time,and its ignition energy and duration is controllable.Application on a multi-fuel rotary internal combustion engine indicates that,under different working conditions,the unit can control light energy and duration of light with the electronic control unit,and by exact matching,engine power performance and smoke can reach its optimal condition.

关 键 词：高能点火 多火花 点火持续时间
