Wholesale Truck Auto Parts Certificated Diesel Particulate Filter Exhaust System

The three-way catalytic converter is a key component in the automobile exhaust treatment system. Its main role is to convert harmful substances in the exhaust (such as carbon monoxide, hydrocarbons, and nitrogen oxides) into harmless substances.

A Diesel Particulate Filter (DPF) is used to reduce particulate emissions. Using high-performance ceramic materials like cordierite or silicon carbide (SiC), these carriers provide high heat resistance and mechanical strength, essential for high-load conditions.

For Gasoline Engines:

• Cars, SUVs, Off-road vehicles
• Motorcycles, Generator sets
• Standards: Euro 1 to Euro 6

For Diesel Engines (DPF):

• Trucks, Buses, Construction machinery
• Ships, Industrial diesel units
• Standards: EPA 2027, Euro 7

1. Shell: Stainless steel for high temperature and corrosion resistance.
2. Damping Layer: Aluminum silicate fiber for sealing and insulation.
3. Carrier: Honeycomb ceramic or metal to maximize surface area.
4. Catalyst Coating: Precious metals (Platinum, Palladium, Rhodium) to accelerate REDOX reactions.

Common positions for installation:

• Exhaust Manifold: Head section for immediate high-temp gas treatment.
• Under Chassis: Drum-shaped section for stable airflow.
• Between Oxygen Sensors: Optimized via sensor feedback loop.
• Before Muffler: Purifies gas before noise reduction.
