DOC Component – Carrier 266102 Muffler refers to a component that integrates the DOC (Diesel Oxidation Catalyst) with a muffler, where the carrier measures 266 x 102.
Main application areas:
- Diesel exhaust treatment: The DOC component can oxidize harmful substances in diesel engine exhaust, such as carbon monoxide (CO) and hydrocarbons (HC), into carbon dioxide (CO₂) and water (H₂O). Meanwhile, the muffler effectively reduces exhaust noise. This muffler, with a carrier size of 266 x 102, is suitable for various types of vehicles—particularly passenger cars and light commercial vehicles that have stringent requirements for both exhaust emissions and noise control.
- Non-road mobile machinery—such as construction equipment like excavators, loaders, and bulldozers, as well as agricultural machines like tractors and combine harvesters—emit exhaust gases and generate noise from their engine operations, both of which require treatment. The DOC component—carrier 266*102 muffler can be installed in the exhaust systems of these machines, delivering dual functionality by purifying exhaust gases and reducing noise simultaneously.
- Generator sets—whether diesel generators used in industrial production, commercial facilities, or as emergency backup power—require control over their exhaust emissions and operational noise. This silencer effectively reduces noise pollution generated during generator operation, while the catalytic action of the DOC further minimizes harmful pollutant emissions from the exhaust, ensuring compliance with environmental regulations.
