TECHNICAL & CONSUMER INFORMATION
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.
Honda uses lean carburetor settings and other systems to reduce the
emissions of carbon monoxide, oxides of nitrogen, and hydrocarbons.
The U.S., California Clean Air Act and Environment Canada
EPA, California and Canadian 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. Some acts that constitute tampering:
•
•
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.
