Abstract： GB 18285-2018 "Limits and measurement methods for emissions from gasoline vehicles under two-speed idle conditions and short driving mode conditions" was implemented on May 1， 2019. Daily inspection of exhaust gas analyzer provides a strong guarantee for the emission test results of two-speed idle conditions and acceleration simulation mode. This paper studies the daily inspection strategy of exhaust analyzer in order to help vehicle inspection institutions improve the accuracy of gasoline vehicle emission inspection.
