摘要
为研究不同点火顺序条件下双火花塞生物质气发动机异步点火缸内燃烧特性,建立了CFD模型,进行仿真计算分析。结果表明,在额定转速额定功率条件下,周围湍动能较大的火花塞先点火时,缸内燃烧速度快,燃烧持续期短,指示热效率高。
In order to study the influence of different ignition sequence on the combustion characteristics of dual -spark plug syngasengine, a CFD model was established and simulated and analyzed. The results show that, in therated speed ,the spark plugs wTith larger turbulence kinetic energy ignited first, the combustion speed is faster and the combustion duration is shorter, ＇which gets higher thermal efficiency.
