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
specified 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 muffler to further treat the engine exhaust.
4.
A secondary air injection valve adds combustion air to ignite unburned fuel in the exhaust.
