研究了柴油机掺烧液化石油气 (LPG)以降低黑烟排放的技术方案 ,并开发出了一种以独特型板调节装置为特征的机械控制式柴油 /LPG双燃料供给系统。发动机不改变原有结构加装该系统后即成为柴油 /LPG双燃料发动机 ,可以同时燃烧柴油和 LPG两种燃料 ,并且在整个工作范围内 ,随着工况变化能够按照预先优化设定的型板型线规律而自动调节柴油 /LPG供给量比例 ,使烟度降低 50 %以上 ,同时满足经济性、动力性以及操作性能等要求 ,此外 ,也可以切换为单独燃烧柴油 ,而不改变发动机的原有性能。该系统结构简单、成本低廉 ,非常适合于改装城市在用公交车 ,降低其黑烟排放
The technical scheme of diesel engine blending liquefied petroleum gas (LPG) to reduce the emission of black smoke was studied and a mechanically controlled diesel / LPG dual fuel supply system featuring a unique type of plate adjusting device was developed. The engine does not change the original structure After the installation of the system to become a diesel / LPG dual-fuel engine, diesel and LPG can simultaneously burn two fuels, and throughout the work area, with the changes in conditions can be pre-optimized type Plate line law and automatically adjust the ratio of diesel / LPG supply to reduce smoke over 50%, while meeting the economic, dynamic and operational performance requirements, in addition, you can also switch to separate combustion of diesel without changing the engine The original performance. The system is simple in structure and low in cost, and is very suitable for refitting the bus in the city and reducing the emission of black smoke
