Emission Control Systems
Evaporative Emission Control System
50 STATE (meets California)
An evaporative emissions control system
uses a canister filled with charcoal to
adsorb fuel vapor from the fuel tank while
the engine is off. The vapor is drawn into
the engine and burned while riding.
Crankcase Emissions Control System
The engine is equipped with a closed
crankcase system to prevent discharging
crankcase emissions into the atmosphere.
Blow-by gas is returned to the combustion
chamber through the air cleaner housing
and throttle body.
Fuel Permeation Emission Control
The fuel tank, fuel hoses, and fuel vapor
charge hoses use fuel permeation control
technologies to prevent fuel vapor
emissions.
Tampering with these components to
reduce or defeat the effectiveness of the
fuel permeation technologies is prohibited.
