针对１３５系列柴油机普遍存在的燃油消耗率高、排放差的问题，开发了一种四角缩口ω紊流型燃烧室燃烧系统．在２１３５Ｇ型柴油机上的试验表明，在不改变原机进气系统的条件下，利用燃烧室的特殊结构在压缩行程后期可产生很强的挤流和紊流，加快了缸内混合气的形成和燃烧速率，缩短了扩散燃烧过程，使柴油机的燃油耗油率、烟度及ＮＯｘ排放有了很大的改善 In view of the common problem of high fuel consumption and poor emission of the 135 series diesel engine, a four-corner constriction ω turbulence combustion chamber combustion system has been developed. Experiments on 2135G diesel engine show that the special structure of the combustion chamber can produce strong squish flow and turbulent flow in the late stage of compression stroke and accelerate the formation of gas mixture in the cylinder without changing the intake system of the original engine And combustion rate, shortening the diffusion combustion process, the fuel efficiency of diesel engines, smoke and NOx emissions have been greatly improved
