气体燃料非平衡等离子体点火技术研究进展

摘要

Non-equilibrium plasma assistant ignition has become a focus of combustion research since high ignition energy, high ignition reliability and short ignition delay. This paper intro-duced the principle of non-equilibrium plasma assistant ignition technique and the progress in non-equilibrium plasma assistant ignition research of gaseous fuels within five years in both ex-perimental and numerical simulation fields, summarized the problems existed in low temperature reaction mechanism research and internal combustion engine utilization of this technique, and prospected the research direction in the future.%介绍了非平衡等离子体点火技术的原理,从试验及数值模拟研究两个方面分别综述了近五年来非平衡等离子体点火技术在气体燃料助燃研究领域的研究进展,指出了现阶段研究在低温反应机理及其验证数据与该技术在内燃机领域的应用研究方面存在的问题,最后展望了非平衡等离子体点火技术未来的研究方向.
