近年来,云南省交通科研所对云南地区使用的解放牌汽车做了大量的发动机功率恢复研究工作。在采用了提高压缩比、改进燃烧室、改进进排气管、调整配气相位等措施后,使发动机的功率在高原地区有较大幅度的恢复,满足了解放牌汽车在云南高原山区拖挂、增载使用要求,取得了显著的经济效益。在此基础上,又进一步开展了以节油为中心的研究工作,根据云南高原山区的特点,对主要车型的化油器进行了系统的高原适应性调整试验(即采用常规、
In recent years, Yunnan Provincial Communications Research Institute has done a great deal of engine power recovery research on Jiefangpai vehicles used in Yunnan. In the adoption of measures to improve the compression ratio, improve the combustion chamber, to improve the intake and exhaust pipe, adjust the gas phase and other measures to make the engine power in the plateau region has a more substantial recovery to meet the liberation of the license plate car in Yunnan plateau mountain trailer , Load requirements, achieved significant economic benefits. On the basis of this, we further carried out the research on fuel economy as the center. According to the characteristics of mountain plateau in Yunnan Province, we carried out systematic plateau adaptability adjustment tests on the main models of carburetors (that is, adopting conventional,
