| 摘 要： | 介绍了内燃机点火技术的研究进展,阐述了内燃机脉冲电晕放电点火新技术所涉及的点火能量、点火效率、燃烧时间和相关化学反应等问题。研究表明,脉冲电晕等离子体点火比传统火花塞点火的效率高12倍,且可在燃烧室内瞬间产生多个大尺度放电通道,实现可燃混合气的多源高效点火;同时,脉冲电晕点火还可诱发产生较火花塞点火多得多的化学反应活性基,从而加速燃烧反应。最后,指出了内燃机脉冲电晕等离子体点火研究的发展方向。

| Abstract: | The development of ignition technology on the internal combustion engine is outlined in this paper.The ignition energy,efficiency,burning time and main chemical reactions of the pulsed corona discharge ignition(PCD) used on internal combustion engine are discussed in detail.The research results show that the ignition efficiency of PCD is 12 times more than the spark plug.PCD produces many discharge channels simultaneously which distribute in a large space volume so as to make multiple sites,high efficiency and extensive ignition possible.PCD generates more chemical radicals than spark plug,therefore the reaction rates are accelerated.The development trends on the application of PCD in internal combustion engines are presented. |
