摘要:

针对目前火花塞点火系统燃烧速度慢、燃烧效率低下等问题,提出了一种利用微波谐振腔实
现多点点火的方法。通过理论分析和模拟仿真、优化, 确定了横磁振荡模式(TM010)谐振腔的尺寸及
其发生谐振时的场强分布。同时采用高速相机和压力传感器, 对点火燃烧过程进行可视化分析和燃烧
压力特性分析。结果表明:与传统的火花塞的点火方法相比,在实验气压为200 kPa 的条件下,这种
方法可以缩短到达压力峰值的时间约15%,并且可以使峰值压力提高约5%。因此,这种方法能够实现
多点点火。

Abstract:

A method to realize multi-point ignition was introduced to solve problems of low combustion speed
and low energy utilization rate in traditional spark plug ignition system. A primary design of a transverse
magnetic resonant mode (TM010) was used for calculation and optimization based on theoretical analysis and
stimulation to determine the size of resonant cavity and to determine the electromagnetic field distribution in the
cavity. A high speed camera and some pressure sensors were used for visualization analysis and combustion
pressure characteristic analysis. The results show that this method shortens the time by 15% when the pressure
arrived at the maximum, and increases the maximum pressure by 5% at the experiment pressure of 200 kPa
compared to the conventional spark plug ignition. Therefore, this method can realize the multi-point ignition.
