The following is an introduction to the "S013YC National VI Silencer":
Structural Composition
- Catalytic Converter: It is a key component of the silencer, usually containing a three-way catalytic converter. Through oxidation-reduction reactions, it converts harmful gases such as carbon monoxide, hydrocarbons, and nitrogen oxides into harmless carbon dioxide, water, and nitrogen.
- Diesel Particulate Filter (DPF): Used to capture particulate matter in the exhaust gas, such as soot particles, to reduce particulate emissions.
- Selective Catalytic Reduction System (SCR): Utilizes ammonia gas produced by the hydrolysis of urea solution to convert nitrogen oxides into nitrogen and water, further reducing nitrogen oxide emissions.
- Silencing Components: Through a series of acoustic designs, such as perforated tubes, expansion chambers, and sound-absorbing materials, it attenuates exhaust noise and reduces noise.
Working Principle
- Exhaust Gas Purification: Exhaust gases from the engine first enter the catalytic converter for preliminary conversion of harmful gases. Then, the particulate filter captures particulate matter, and the SCR system reduces nitrogen oxides with the help of a catalyst.
- Noise Reduction: When exhaust gases flow through the silencing components, the perforated tubes disperse sound waves, the expansion chambers reflect and attenuate them, and the sound-absorbing materials absorb them, thus reducing noise.
Product Advantages
- Meets National VI Emission Standards: It has high purification efficiency and can make various pollutant indicators in the exhaust gas meet the National VI emission standards, reducing environmental pollution.
- Good Noise Reduction Effect: The optimized silencer structure design effectively reduces engine exhaust noise and improves driving comfort.
- Reliable Durability: High-temperature and corrosion-resistant materials such as stainless steel and advanced manufacturing processes are used to ensure stable operation in long-term high-temperature and high-pressure working environments, extending service life.
