EXHAUST EMISSION CONTROL SYSTEM
Exhaust emission control
(for EURO3 and other markets)
Super 8 scooters for certain markets are equipped with an emission control system which draws fresh air into the exhaust
system to complete combustion of hydrocarbons that were not burned in the engine’s combustion chamber process. This
system also includes a catalytic converter in the muffler, and does not use any engine power, and does not affect the driveablity
of the scooter. It does reduce the scooter’s exhaust emissions levels so they meet Euro 3-required specifications.
