摘要
轻型车尾气排放标准由国五升级到国六,实现了稳态测试循环向更接近实际行驶状况的瞬态循环转变。与国五排放标准相比,国六标准的单车污染物排放加严至少30%。首次提出实际行驶污染物排放试验的要求,限制了实际道路排放与试验室排放的差异。新增加油过程污染物排放试验要求,严格控制挥发性有机物VOCS排放。增加OBD的监控项目并增大监测频率,严格监测汽车尾气排放。
The emission standard of light vehicles has been upgraded from China Ⅴ to China Ⅵ, which realizes the transition from steady-state test cycle to transient test cycle which is closer to the actual driving condition. Compared with China Ⅴ emission standard, the emissions of China Ⅵ emission standard are tightened by at least 30 %. The requirement of RDE test is put forward for the first time, which limits the difference between actual road emissions and laboratory emissions. The on-board refueling vapor recovery (ORVR) test is added to strictly control volatile organic compounds (VOCS) emissions. Increased OBD monitoring projects and monitoring frequency can strictly monitor vehicle exhaust emissions.
