Yunnan Plateau Lpg City Bus Practicality Test Research

The urban passenger train of Yunnan is mainly a carburetor car taking petrol as fuel at present, the waste gas discharged is one of the focal points of the atmospheric pollution sources of urban area. Yunnan locate in plateau, engine inflate efficiency drop , liquefied petroleum gas device and engine mismatch, lack the essential plateau and adjust the technological scheme. This text employs the method to test, further investigated to the choice , transformation of engine and adjustment of liquefied petroleum gas device of the liquefied petroleum gas device of the urban passenger train of plateau and the discussion .This text has analyzed the plateau characteristic of the urban passenger train liquefied petroleum gas fuel in the plateau at first, transform the scheme and analyze and study the systematic test to the liquefied petroleum gas of the urban passenger train of plateau , transform the scheme after putting forward the plateau adaptability based on urban passenger train liquefied petroleum gas fuel in the plateau. Secondly, on this basis, have proposed the road testing program of the urban passenger train of liquefied petroleum gas, research and analyse the road test of transforming the vehicle. Finally to refit vehicle put into , run , test actually , analyze , prove , transform reality of scheme employ result and liquefied petroleum gas dependability of using of device, propose " Yunnan province automobile-used liquefied petroleum gas device refit and maintain the technical requirement".The research results herein, through the application in running actually of urban passenger train of Yunnan, prove , in a situation that vehicle motive force decreasing amplitude is smaller, use scheme this refit to urban liquefied petroleum gas that passenger train go on, can improve the discharge of the urban passenger train, put forward " Yunnan province automobile-used liquefied petroleum gas device refit and maintain technical requirement " can improve Yunnan liquefied petroleum gas device refit and maintenance regulatory, have important realistic meaning and the society , economic worth..
