摘　　要：在高原环境条件下 ,针对柴油机燃用LPG的经济性、动力性和排放特性进行了研究。柴油机掺烧LPG后 ,在一定的掺烧比下 ,动力性有所提高 ,经济性有所改善 ,碳烟排放降低幅度较大 ,但发动机振动加大 ,噪声和排温升高。Under the environmental conditions of plateau area, the power performance, economic performance and soot emissions of diesel engines burning the mixture of LPG and diesel oil have been studied. The results indicate the diesel oil/LPG dual fuel engines power performance and economic performance get better, soot emissions decrease evidently, but vibration, noise and temperature of exhaust gas increase, which is the theoretical base of using diesel oil/LPG dual fuel engine in plateau areas.
