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 appropriate air/fuel ratios and other emissions control
systems to reduce the emissions of carbon monoxide, oxides of nitrogen and
hydrocarbons.
Additionally, Honda fuel systems utilize components and control
technologies to reduce evaporative emissions.
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 Honda engine emissions 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 intake, fuel, or exhaust system.
• Altering or defeating the governor linkage or speed-adjusting mechanism
to cause the engine to operate outside its design parameters.
