摘　　要：针对LPG 柴油双燃料发动机的燃烧特性进行了研究。在相同的当量小时油耗、相同的转速下,随着海拔高度的增加,双燃料发动机的缸内压力减小,压力升高率降低,放热率降低;随掺比的增加,缸内压力升高,压力升高率增大,放热率升高。Under the environment conditions, the combustion performance of the diesel oil/LPG dual fuel engine has been studied. The results indicate that: under the same consumption of fuel and rotate speed, the pressure in the cylinder, the increasing rate of pressure and the releasing rate of heat energy are all decreased with the increase of altitude,but are all higher than primary diesel's.
