摘　　要：根据燃烧分析仪测录的示功图对LPG/柴油双燃料发动机不同工况的燃烧百分率和燃烧率进行计算 ,分析其燃烧特性 ,得出了有关双燃料发动机燃烧的一些结论 ,为合理组织燃烧过程和提高双燃料发动机技术水平提供借鉴。Percentage of burned fuel and combustion rate of a LPG/diesel dual fuel engine under different working conditions are calculated depending on the determined indicator diagrams. The combustion characteristics are deeply investigated. Conclusions about combustion characteristics of a dual fuel engine are reached, which establishes foundations for logically organizing the combustion process and provides guidance for improving technique of dual fuel engines.
