Emission Control System Information - Honda Power Equipment EZ5000 Owner's Manual

EMISSION CONTROL SYSTEM INFORMATION
Source of Emissions
The com bustion 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 orderto
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.
