摘　　要：为解决我国轻型汽车污染物排放控制的问题,在现有国五排放标准的基础上,分析了我国第六阶段轻型汽车排放控制标准的特点及发展变化,对汽车燃油蒸发排放控制提出了新的限值及型式试验要求。研究结果表明:新标准从蒸发污染物排放、加油碳氢化合物排放、车载诊断系统3个方面着手对轻型汽车排放进行控制,以减少汽车HC和CO的排放。In order to solve the problem of pollutant emission control of light vehicles in China, the characteristics and development of China's sixth-stage light vehicle emission control standards are analyzed based on the existing national five emission standards , and new limits are proposed for vehicle emission control and type test requirements. The results show that the new regulations control light vehicle emission from three aspects , i.e. evaporative pollutant emission , fueling hydrocarbon emission and OBD system in order to reduce vehicle HC and CO emissions in practical applications.
