摘要
油耗法规测试循环工况将由新标欧洲测试循环(NEDC)工况切换至全球轻型车统一测试循环(WLTC)工况.为了探讨测试循环工况切换对不同能源类型车辆油耗的影响,试验选取一台满足国Ⅵ排放标准的传统燃油车与一台满足国Ⅵ排放标准的48 V轻混车辆,分别进行WLTC和NEDC工况下的油耗试验,得到两种能源类型车辆在WLTC与NEDC工况下的试验室油耗数据.数据分析结果表明,WLTC工况较NEDC工况的传统燃油车认证油耗升高了6.7%、48 V轻混车辆认证油耗升高了14.1%.
The fuel consumption regulation test cycle will be switched from NEDC test cycle to WLTC test cycle.In order to explore the impact of test cycle switching on fuel consumption of vehicles with different energy types,a traditional fuel vehicle meeting the national sixth emission standard and a 48 V light hybrid vehicle meeting the national sixth emission standard were selected for WLTC test cycle and NEDC test cycle respectively.The fuel consumption certification data under WLTC test cycle and NEDC test cycle were obtained and the characteristics were analyzed.The results show that the fuel consumption of traditional fuel vehicle certification increases by 6.7%and that of 48 V light hybrid vehicle increases by 14.1%under WLTC test cycle compared with NEDC test cycle.
