Vehicle Inspection Notice
1. Motorcycle installation position: 50cm away from the engine for best results
2. Do not test with a cold engine
3. Before testing, the vehicle needs to be idle for about 20 minutes, or after riding for 0.5-1 hour before testing
Working Principle
Motorcycle catalytic converters use a METAL honeycomb structure coated with precious metal catalysts (Pt/Pd/RH) to promote oxidation and reduction reactions as hot exhaust gases pass through.
Main Reactions:
CO → CO₂ (carbon monoxide to carbon dioxide)
HC → CO₂ + H₂O (unburned hydrocarbons to carbon dioxide and water vapor)
NOx → N₂ + O₂ (nitrogen oxides to nitrogen and oxygen)
These chemical reactions significantly reduce air pollutants, helping your motorcycle meet emission regulations and run cleaner.
Common Misunderstanding: Catalytic Converter vs. Muffler
Many riders confuse the catalytic converter with a muffler, but they are completely different components:
|
Feature |
Catalytic Converter |
Muffler |
|
Main Function |
