汽车节能是当今世界各国汽车和公路运输界极为关注的重大课题,本文论及了:由于我国汽车吨位构成不合理导致能耗量较大;汽车拖挂运输可部分调整目前这种不合理局面;同时还结合实际,阐明了汽车拖挂对节能的主要理论依据。交通部于1983年下达的《公路客货挂车行业规划》(草稿)中要求到本世纪末交通部门的营运货车拖挂率为54％,非营运货车拖挂率为20％。依据国家经委宣布1984年全国民用汽车保有量为230万辆,挂车保有量为18万辆左右(1983年统计数),仅占总车辆数12.8％。因此现有挂车量远远不能适应四化建设需要,发展拖挂运输宗旨在于节能、提高运输生产率、降低成本。
Automobile energy saving is a major issue that the automobile and road transport circles all over the world pay close attention to nowadays. This article discusses that: due to the unreasonable composition of the tonnage of automobiles in our country, the energy consumption is larger; the automobile trailing transport can partially adjust the current unreasonable situation; At the same time also combined with the actual situation, illustrates the main theoretical basis for energy saving car trailer. The Ministry of Transport's “Highway Trailer Trailer Industry Plan” (draft) issued in 1983 required that the traffi cion rate of trailers operated by the transport sector be 54% by the end of this century, and that of non-operating trailers be 20%. According to the State Economic Commission announced in 1984 the country's 2.3 million civilian car ownership, trailer ownership of about 180,000 (1983 statistics), accounting for only 12.8% of the total number of vehicles. Therefore, the current amount of trailers can not meet the needs of the four modernizations. The purpose of developing trailers is to save energy, increase transport productivity and reduce costs.
