介绍了气体发动机的发展过程和研究现状，以及所应用的Miller循环技术、EGR技术、混合气形成供给技术。着重介绍了气体机发展过程中出现的各种点火技术，并就这些点火技术对发动机排放和热效率的影响作了对比分析。分析表明：在目前点火技术下，气体发动机稀燃程度已经达到λ=2．0左右，热效率也提高到45％以上。气体发动机和传统燃料发动机相比：效率相当，排放低，因此，气体发动机有着不可限量的发展潜力。

The development and research state of gas engines are briefly introduced. The technologies applied on gas engines, including Miller cycle, EGR and the mixture gas formation and supplyment are presented. The varied kinds of the ignition technologies during the gas engine development history are in- troduced in detail. Meanwhile, the influence of different ignition technologies on emission and thermal ef- ficiency are compared and analyzed. The analysis results indicate that with the now available ignition technology, the lean burn has reachedλ =2.0 or so, thermal efficiency has improved to more than 45% above. Compared with traditional engine, it features lower emissions with the same efficiency. Therefore, gas engine has unlimited development potential,
