Emission Control Information
To protect the environment in which we all live, Norton motorcycles (UK) ltd has incorporated crankcase
emission (1) and exhaust emission (2) control systems in compliance with applicable regulations of the
United States Environmental Protection Agency and California Air Resources Board. Additionally, Norton
has incorporated an evaporative emission control system (3) in compliance with applicable regulations of
the California Air Resources Board on vehicles sold in California only.
Crankcase Emission Control System:
This system eliminates the release of crankcase vapours into the atmosphere. Instead, the vapours
are routed through an oil separator to the intake side of the engine. While the engine is operating,
the vapours are drawn into combustion chamber, where they are burned along with the fuel and
air supplied by the injection system.
Exhaust Emission Control System
This system reduces the amount of pollutants discharged into the atmosphere by the exhaust of
this motorcycle. The fuel and ignition systems of this motorcycle have been carefully designed and
constructed to ensure an efficient engine with low exhaust pollutant levels.
Evaporative Emission Control System
Vapours caused by fuel evaporation in the fuel system are not vented into the atmosphere. Instead,
fuel vapours are routed into the running engine to be burned, or stored in a canister when the
engine is stopped.
The Clean Air Act, which is the Federal law covering motor vehicle pollution, contains what is commonly
referred to as the Act’s “tampering provisions”.
