Champ d’application
This standard applies to the type testing and quality inspection of motor vehicle exhaust spark arresters. It covers various types of arresters, including generally equipped, temporarily equipped, integral, and liquid cooling types. It is essential for manufacturers producing exhaust systems for vehicles operating in fire-prone environments.
Exigences techniques
The standard specifies mandatory performance criteria to ensure the arrester effectively cools exhaust gases and extinguishes sparks. Key requirements include the spark extinguishing performance, which dictates that collected active carbon particles at the outlet must not exceed a specific percentage of the total test carbon. Additionally, it mandates limits on engine performance impacts, specifically concerning the power decreasing ratio and oil consumption rate increasing ratio at 40% power. The arrester must not negatively affect original exhaust noise, emissions, or exhaust temperature. The standard also sets structural integrity requirements, demanding resistance to vibration and drop impacts without structural damage or permanent deformation. For liquid cooling types, specific thermal limits and continuous operation capabilities under full load are enforced, along with mandatory acoustic and optical alarms for cooling medium loss. Material requirements dictate the use of at least cold-rolled steel sheets.
Méthodes d’essai
Testing procedures evaluate the arrester using a specialized performance test device utilizing active carbon particles prepared according to GB/T 7701.7. Engine performance impacts are measured referencing GB/T 6072.1 for power and fuel consumption, GB/T 4759 for noise, and GB 3847 for emissions. Structural durability is verified through high-frequency vibration tests and free-fall drop tests from specified heights. Liquid cooling models undergo specific temperature and continuous operation tests to verify cooling capacity and alarm functionality.
