Description

Technical Field

[0001] This utility model relates to the field of motor vehicle environmental emission testing technology, and in particular to a device for identifying black smoke during motor vehicle emission testing. Background Technology

[0002] Vehicles emitting large amounts of black smoke during operation pose a serious threat to the environment and human health. According to GB3847-2018 "Limits and Measurement Methods for Pollutant Emissions from Diesel Vehicles (Free Acceleration and Loaded Deceleration Method)" 8.2.2, "If a vehicle emits clearly visible smoke or the smoke value exceeds Greenman Level 1, the emission inspection is deemed unqualified," and HJ1237-2021 "Motor Vehicle Emission Lifting Inspection Standard" 7.5, "If visually visible black or blue smoke is emitted during the inspection process, the appearance inspection is deemed unqualified according to GB18285 and GB3847," both clearly stipulate that if clearly visible black smoke is present during vehicle testing, the appearance inspection should be deemed unqualified. However, currently, this result can only be confirmed by the inspector's opinion, which is highly subjective and fails to reflect the fairness and impartiality of the inspection process.
