City bus idle stop-start system simulation analysis

摘要

Idle stop-start system is a new energy-saving product, which can obtain a good fuel economy and reduce emissions for the city bus. The work principle and mechanical structure are analyzed in this paper. The key technologies of idle-stop-start system are analyzed based on this. Then the idle-stop-start system is modeled and analysised based on AVL Cruise. Last, the fuel economy is simulated and analysised under the Chinese typical cycle run, the merit of idle-stop-start system is proved.
