机动车排放会给人类健康和生态环境带来不利影响,必须采取强制措施加以控制。中国从2010年7月起开始实行国Ⅲ标准,包括对12000km耐久性的要求,就此而言,该标准比欧Ⅲ标准更为严格。目前,在全球范围实施的2种减少废气排放的主要方法是:改进发动机设计和使用后处理装置。
Vehicle emissions will have adverse effects on human health and the environment, and must be coercively controlled. Since July 2010, China started to implement the national standard Ⅲ, including the requirement for durability of 12000km. In this regard, the standard is more stringent than the Euro Ⅲ standard. At present, the two main approaches to reducing emissions globally are: improving engine design and using aftertreatment devices.
