Scope

Main technical content: To reduce the emission levels of pollutants from motor vehicles, improve ambient air quality, and safeguard human health, China implemented GB 18285-2018, "Emission Limits and Measurement Methods for Petrol Vehicles (Double Idling Method and Simplified Operating Condition Method)" and GB 3847-2018, "Emission Limits and Measurement Methods for Diesel Vehicles (Free Acceleration Method and Loaded Deceleration Method)" simultaneously on May 1, 2019. Among them, the "Method and Judging Criteria for OBD Inspection" were added. Motor vehicle inspection institutions use OBD diagnostic tools to conduct OBD inspections on motor vehicles and use the results as the basis for judging whether the pollutant emissions from motor vehicles meet the standards. The formulation of this document can unify the technical requirements for OBD diagnostic tools used in motor vehicle emission inspections, standardize the production and use of OBD diagnostic tools for motor vehicle emission inspections, ensure the accuracy of inspections using OBD diagnostic tools for motor vehicle emission inspections, and support the implementation of national standards. This document proposes the inspection items and methods for OBD diagnostic tools used in motor vehicle emission inspections.
