1. Core Positioning​ A key purification component of automotive exhaust systems, installed between the exhaust manifold and muffler. It converts carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOx) in exhaust gas into harmless CO₂, H₂O, and N₂ via catalysts (Pt/Pd/Rh), meeting emission regulations. Compatible with fuel vehicles and hybrid vehicles.​ 2. Core Functions​ High-Efficiency Purification: Harmful gas conversion rate ≥95%, complying with China National Emission Standard VI (GB 18352.6-2016) and Euro 6d;​ High-Temperature Resistance: Stainless steel shell + ceramic substrate, temperature resistance up to 800℃, adapting to high-load exhaust conditions of engines;​ Fault Prompt: Triggers OBD fault codes (e.g., P0420) when the substrate is damaged or catalyst fails, facilitating maintenance;​ Low Back Pressure: Optimized flow channel design, low exhaust resistance, no impact on engine power output.​ 3. Core Advantages​ Strong Compliance: Certified by national environmental protection authorities, ensuring vehicle emission tests pass;​ High Durability: Catalyst coating anti-aging, service life ≥8 years/160,000km;​ Easy Installation: Flange/welded interface, direct OE replacement without modifying the exhaust system.​ 4. Adaptability​ Vehicles: Fuel/hybrid passenger vehicles (sedans/SUVs), commercial vehicles (light trucks/buses);​ Displacement: Adapts to mainstream 1.0L-3.0L displacement engines, supporting custom models for large displacement (>3.0L).​ 5. Service Support​ Contact customer service for adapted vehicle lists and installation drawings; free installation technical guidance provided.
