Carbon monoxide (CO) → Carbon diox
Product introduction
Premium catalytic converter for Changan Star 474，This product we use high-quality raw materials 409 stainless steel, and with high flow ceramic carrier, to help each car can purify exhaust gas, reduce fuel consumption, improve power, and extinguish engine failure lights!
1. Basic structure and working principle
Physical structure
Appearance and location: Shaped like a "military kettle", it is installed at the front end of the exhaust system (near the engine exhaust manifold), between the front and rear oxygen sensors, and is connected to the exhaust pipe through a flange.
Interior design:
Ceramic carrier: porous honeycomb ceramic structure, the mesh number is usually 600-900 mesh, the pores are evenly arranged to balance the exhaust resistance and purification efficiency.
Precious metal coating: The surface is covered with platinum (Pt), palladium (Pd), rhodium (Rh) and other precious metals, as a catalyst to promote REDOX reaction.
Shell material: double-layer stainless steel cylinder wrapped in ceramic carrier, the middle filled with thermal insulation material, high temperature resistance (up to 800℃), suitable for frequent start-stop commercial vehicle conditions.
Working principle
When the tail gas passes through the catalytic converter, the precious metal catalyst activates the following chemical reactions:
CO (Carbon monoxide) → CO₂ (carbon dioxide) (oxidation reaction)
HC (hydrocarbon) → H₂O (water) + CO₂ (oxidation reaction)
NOx (nitrogen oxide) → N₂ (nitrogen) + O₂ (oxygen) (reduction reaction).
Through the above transformation, the exhaust emissions meet the national 4 to national 6 standards, reducing environmental pollution.
Second, the core advantages of Changan Star 474 models
Special car design
Size and interface matching: Customized according to 474 engine displacement (e.g. 1.3L or 1.5L), ensuring seamless docking with the exhaust manifold and avoiding the loss of catalytic efficiency caused by gas leakage.
High temperature resistance and anti-poisoning: According to the characteristics of high load operation of commercial vehicles, optimize the ratio of precious metals to reduce the "catalyst poisoning" caused by inferior fuel sulfur and lead components.
Economy and durability
4.
Long service life: under normal working conditions, the life can reach 8-100,000 kilometers, and the abandoned catalytic converter can recover precious metals (residual value of about hundreds of yuan), further reducing the cost of use.
Performance optimization
Reduce exhaust back pressure: Reasonable mesh design to avoid high mesh caused by poor exhaust, reduce engine power loss, improve acceleration response and fuel economy.
Protect associated components: prevent unpurified exhaust gas from corroding the oxygen sensor, damaging the exhaust system, and avoid exhaust high-temperature ablation problems caused by clogging.
3. Maintenance and troubleshooting
Common fault
Blockage: Carbon or lead/sulfur poisoning leads to increased exhaust resistance, which is manifested as decreased power, increased fuel consumption, and exhaust odor.
Ceramic carrier damage: severe turbulence or impact may make the carrier shatter, causing abnormal sound or purification failure 4.
Maintenance suggestion
Regular cleaning: Soak with oxalic acid or special cleaning agent every 20-30,000 kilometers to remove carbon deposits (note: serious blockage needs to be replaced).
Oil selection: Use regular fuel to avoid excessive sulfur content resulting in catalyst poisoning.
Check and replace: If the engine fault light is on (such as fault code P0420) and the exhaust gas of the annual inspection is not up to standard, it is necessary to detect and replace the genuine catalytic converter in time.
Identify genuine products
Appearance features: genuine ceramic carrier color white, uniform pores; Counterfeits are often yellow and loosely assembled 4.
Channel verification: Purchase and check the security code through official channels to avoid the deterioration of emissions caused by inferior parts.
Iv. Summary
Changan Star 474 three-way catalytic converters achieve a balance between environmental compliance and practicality through efficient exhaust gas purification, adaptation to engine characteristics and low cost maintenance. Its design takes into account the needs of high frequency use of commercial vehicles, and is a key component to ensure vehicle performance and extend component life. Owners need to pay attention to regular maintenance and genuine replacement to give full play to its environmental protection and economic value.
