摘要本文提出了一种组织点燃式发动机稀燃速燃的紊流型燃烧室,在一台自行设计改装的单缸试验机上对浴盆型、碗型、火球型、紧凑型、紊流型等五种燃烧室进行了对比试验研究,获得了采用不同燃烧室时发动机的性能、排放指标和燃烧特性参数,结果表明采用紊流型燃烧室时发动机具有最佳的综合性能指标,外特性燃油消耗率曲线平坦,最低油耗率为260g/(kW·h),HC、CO排放下降,动力性能和操纵性能得到改善.
Abstract This paper presents a turbulence-type combustor for ignition of a spark-ignited engine with a lean burn speed. The steam turbine, bowl type, fireball type, compact type, turbulence type, etc. are tested on a self-designed single- The results show that the engine has the best comprehensive performance index when the turbulent combustion chamber is adopted, and the external characteristic fuel consumption rate The curve is flat, the minimum fuel consumption rate is 260g / (kW · h), HC, CO emissions decline, power performance and maneuverability improved.
