12. APPENDIX A - EMISSION CONTROL SYSTEM
Your generator has an engine that has been approved by the California Air Resources Board. Other than the tune up procedures
specied in the Maintenance section, no additional maintenance is required.
The emission control system has the following components:
1. Fuel System: The fuel tank, cap, indicator and hoses are specially designed and constructed to not allow fuel vapors to permeate
and be released to the atmosphere.
2. A carbon activated canister collects gasoline vapors from the fuel tank and returns them to the combustion chamber for burning.
3. A catalyst is built into the mufer to further treat the engine exhaust.
4. A secondary air injection valve adds combustion air to ignite unburned fuel in the exhaust.
