Abstract
China is the world’s biggest motorcycle producer and consumer, the capacity of production has been to 20 million units per year at present, that represent more than 50 percent of total worldwide production. National motorcycle inventory amounted to 80 million. But most products have problems owning to low technical levels, heavily environment pulltion, high energy consumption, and the use of these motorcycles caused serious environmental pollution problems. Motorcycle Emission Limits and Measurement Methods (mode method, china stage Ⅲ)” and “Moped Emission Limits and Measurement Methods (mode method, china stage Ⅲ)” that will come onto effort in July 1st, 2008 will greatly improve the requirement for the level of motorcycles and mopeds emission control. Formulating more stricter standards of motorcycle and moped emission will further promoted the technology development of China’s motorcycle industry, supervise motorcycle manufacturing enterprises to introduce new technologies and new materials, to reduce the emissions for environment protection. Now the most pressing problem facing the domestic motorcycle manufacturing enterprises is reducing emissions and improving fuel efficiency.Major domestic motorcycle manufacturing enterprises begin to focus on hybrid power motorcycle. Hybrid power motorcycle can greatly reduce emissions and improve fuel efficiency, while assure sufficient power output, which is unexampled the traditonal motorcycles and electric vehicles. Since the electric vehicle technilogy is mature today, breaking energy recycle technology is also applied to the design of hybrid power motorcycle, to improve the energy utilization ratio. This article analyze breaking energy recycle theroy and the constraint condition of breaking energy recycling, research vehicle dynamics and the brake performance under different braking modes, select the most suitable breaking energy recycle mode according to the pratical situation of motorcycle uses, making the new model more environmentally friendly and reducing the use and production costs.
