Research On Operation Of Bus Fuel Consumption Limits And Measurement Methods

At present, shortage of energy supply is a bottleneck problem that restrains the rapid and stable development of national economy of China, the solution to the energy problem is getting to be a significant strategy for social stability and economic sustainable development. Traffic and transportation industry is one of the service industries as well as the foundation of the national economy. On the one hand, it provides solid guarantee for the development of Chinese economy, on the other hand, it is a major industry that possesses and consumes much energy sources. Road transportation consumes much chemical and petroleum sources each year, such as petrol and diesel oil, which accounts for an increasing ratio of petroleum energy consumption in China. Therefore, it will provide a great effect on the energy saving and pollution discharge to control the use of high-energy-consumption vehicles in road transportation.Firstly, this dissertation studies the status and regulation of fuel consumption of vehicles home and abroad, investigates the fuel consumption limits and the regulation in other countries and uses them as reference for determining the fuel consumption limits of China; secondly, a measuring method for fuel consumption verifying test is formulated in accordance with the special situation of China, a concept named comprehensive fuel consumption is suggested on the basis of above research, and a classification of vehicles is determined; The data of equal-speed fuel consumption of Chinese passenger vehicle are collected and researched according to the methods of data collection, accordingly, the distribution verification is made for the equal-speed fuel consumption curve of each class of vehicle, and a corresponding fuel consumption limits are offered through calculating.Based on a good deal of investigation and test verification, this dissertation accurately makes clear the fuel consumption degree of commercial vehicle for passenger transportation in China, takes the trend of relevant international standard into consideration as well as the actual demand of road transportation, provides fuel consumption limits of commercial vehicle for passenger transportation that can serve as an instruction for the control of fuel consumption in vehicle manufacturing and road transportation industry and can drive the technological improvement, which is significant for regulating the development road transportation industry in China, and will achieveoutstanding effect on energy saving and pollution discharge.
