| 摘 要： | 针对摩托车发动机经济性差、排放高的问题,笔者在一台加装了双火花塞和进气补气系统的单缸摩托车发动机上,在不同转速条件下,就双火花塞点火和补气对内燃机燃烧与排放特性的影响进行了试验研究。试验结果表明,采用双点火配合进气补气的方法可以有效降低发动机CO、HC排放及比燃油消耗率。在转速为3500r.min-1的条件下,采用双点火配合进气补气的发动机比燃油消耗率较原机降低约12.5%。在发动机转速高于3000r.min-1时,采用双点火也可以在一定程度上改善发动机经济性并降低CO和HC排放。但NOx排放在双点火条件下较原机略有升高。

| Abstract: | Concerning the low fuel economy and high toxic emissions from the motor engines,this paper experimentally investigated the effects of double spark ignition and air supplement on performance of a spark-ignited(SI) gasoline engine.The test was conducted on a modified single cylinder motor engine equipped with two spark plugs and an air supplementary system under various speeds.The test results demonstrated that the engine brake specific fuel consumption(BSFC) and CO and HC emissions effectively decreased afte... |
