Kymco Clean Air System (For Euro 2) - KYMCO Vitality 50 Owner's Manual

11.KYMCO CLEAN AIR SYSTEM (FOR EURO 2)

The KYMCO Clean Air System is a secondary air suction system that helps the exhaust gases to
burn more completely. When the spent fuel charge is released into the exhaust system, it is still
hot enough to burn. The system allows extra air into the exhaust system so that the spent fuel
charge can continue to burn. This continued burning action tends to burn up a great deal of the
normally unburned gases, as well as changing a significant portion of the poisonous carbon
monoxide into harmless carbon dioxide.
