Emission Control System Information - Honda FG100 Owner's Manual

TECHNICAL & CONSUMER INFORMATION

EMISSION CONTROL SYSTEM INFORMATION

Source of Emissions
The combustion process produces carbon monoxide, oxides of nitrogen, and hydrocarbons. Control of hydrocarbons
and oxides of nitrogen is very important because, under certain conditions, they react to form photochemical smog
when subjected to sunlight. Carbon monoxide does not react in the same way, but it is toxic.
Honda utilizes lean carburetor settings and other systems to reduce the emissions of carbon monoxide, oxides of
nitrogen, and hydrocarbons.
The U.S and California Clean Air Acts
EPA and California regulations require all manufacturers to furnish written instructions describing the operation and
maintenance of emission control systems.
The following instructions and procedures must be followed in order to keep the emissions from your Honda engine
within the emission standards.
Tampering and Altering
Tampering with or altering the emission control system may increase emissions beyond the legal limit. Among those
acts that constitute tampering are:
•
Removal or alteration of any part of the intake, fuel, or exhaust systems.
•
Altering or defeating the governor linkage or speed-adjusting mechanism to cause the engine to operate outside
its design parameters.
Problems that may Affect Emissions
If you are aware of any of the following symptoms, have your engine inspected and repaired by your
servicing dealer.
•
Hard starting or stalling after starting.
•
Rough idle.
•
Misfiring or backfiring under load.
•
Afterburning (backfiring).
•
Black exhaust smoke or high fuel consumption.
Replacement Parts
The emission control systems on your new Honda engine were designed, built, and certified to conform with EPA and
California emission regulations. We recommend the use of genuine Honda parts whenever you have maintenance
done. These original-design replacement parts are manufactured to the same standards as the original parts, so you
can be confident of their performance. The use of replacement parts that are not of the original design and quality may
impair the effectiveness of your emission control system.
A manufacturer of an aftermarket part assumes the responsibility that the part will not adversely affect emission
performance. The manufacturer or rebuilder of the part must certify that use of the part will not result in a failure of the
engine to comply with emission regulations.
Maintenance
Follow the maintenance schedule on page 18. Remember that this schedule is based on the assumption that your
machine will be used for its designed purpose. Sustained high-load or high-temperature operation, or use in unusually
wet or dusty conditions, will require more frequent service.
