文中以汽车排放试验用密闭蒸发舱为研究对象,针对密闭室的密闭性,提出了采用标准气体法对变温密闭蒸发舱密闭室进行校准,以此保证蒸发污染物排放试验数据的准确可靠,为汽车试验提供基础性保障。
In this paper, the closed evaporating compartment of automobile emission test is taken as the research object. According to airtightness of airtight chamber, a standard gas method is adopted to calibrate the temperature-airtight closed-chamber airtight chamber so as to ensure the accurate and reliable experimental data of evaporative pollutant emission. Automotive tests provide basic protection.
