摘要
在小型天然气发动机上,燃料喷射时间对发动机的燃油消耗率及HC、NOx排放有很大的影响。每个工况都存在一个最佳的燃料喷射时间,标定过程中,每个工况匹配最佳的燃料喷射时间,可改善发动机的燃烧特性,在一定程度上提高发动机的燃油经济性及动力性,降低排放。
For turbo charged CNG engine, injection tine has a great influence, on fuel consumption and HC and NOx emissions. For every operating mode, quirements. During the Dyno calibration for a CNG gine combustion characteristics and promote engine injection time should be matched for performance re- engine, the optimized injection time could improve en- economy, power and emission performance.
