内燃机微波点火研究进展综述

摘要

The status and characteristics of microwave ignition for internal combustion engine at home and abroad were summarized and discussed. The current microwave ignition technology mainly included microwave, resonator torch ignition (MTI), microwave radiation space ignition (MSI) and microwave plasma assisted ignition (MAI). The potential ignition for the technology was introduced. It was pointed out that microwave ignition was likely to extend the lean burn limit greatly. Compared with traditional ignition, microwave ignition had the greater potential of energy saving and emission reduction.%综述了国内外运用于内燃机的微波点火的研究现状和技术特点,将微波点火主要分为3类,即微波谐振炬点火(Microwave resonator Torch Ignition,MTI)、微波辐射空间点火(Microwave radiation Space Ignition,MSI)、微波等离子体助燃(Microwave plasma Assisted Ignition,MAI),并介绍了微波点火可能的着火燃烧机制.指出微波点火有可能大幅拓展发动机稀燃极限,相对传统火花点火有显著的节能和减排潜力.
