| 摘 要： | 通过控制变量设计试验方案,研究定容燃烧弹内的预混燃烧特性以及火花塞数量和布置方式对天然气预混火焰传播性质的影响.利用Fluent软件对各方案进行数值模拟计算,计算结果表明,天然气预混燃烧速率比汽油小,采用双火花塞布置可有效提高燃烧速率,缓解天然气发动机动力性不足,为天然气速燃技术的进一步研究提供理论基础.

| Abstract: | This article introduces design schemes for the research on the premixed combustion in the constant volume bomb and influences on flame propagation of natural gas due to the layout of spark plug.With the CFD simulation calculation based on Fluent,it seems that the burning rate of gasoline is faster than natural gas,and dual spark plugs can make fast combustion of natural gas,which can provide a theoretical method to solve the bad performance of power for CNG engines. |
