MAINTENANCE &ADJUSTMENTS
Emission Control System 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.
The U.S. and California Clean Air Act EPA and California regulations require all manufacturers to
furnish written instruction 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:
l
Removal or alteration of any part of the intake, fuel, or
exhaust systems.
l
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 authorized Honda
servicing dealer.
l
Hard starting or stalling after starting.
l
Pough idle.
l
Misfiring or backfiring under load.
l
Afterburning (backfiring).
l
Black exhaust smoke or high fuel consumption.
