高原地区混合动力公交客车运行适应性分析

Analysis of Hybrid City Bus Running Adaptability in Plateau

基于昆明市新能源汽车示范运行信息化管理与监控系统,对高原地区同一公交线路上同步运行的混合动力公交客车和纯柴油公交客车进行了运行数据采集,对运行车辆的油耗数据和故障情况进行了分析研究。结果表明:该混合动力公交客车节油效果明显,平均百公里油耗较纯柴油公交客车降低了11.34%;混合动力公交客车燃油经济性波动较大,受高原环境和驾驶员操作习惯影响明显;高原环境的差异性和技术条件的不成熟导致混合动力公交客车故障率明显高于纯柴油公交客车,且随运行时间增长会出现一定程度的增加。

Based on the information management and monitoring system for the new energy vehicles demonstra- tion running in Kunming, the hybrid buses and pure diesel buses running data were collected on the same bus line in plateau, compared fuel economy and failure of tested buses. The results show that the hybrid bus could save fuel obviously, that the average fuel consumption of 100 km reduces about 11.34% compared with pure diesel buses; the hybrid bus fuel economy is fluctuant, plateau environment and the habits of the drivers have significant effects on the fuel economy of hybrid bus. The failure rate of hybrid buses is significantly higher than pure diesel buses, and will increase with the running time growth.
