Emission Control System Information

Source of Emissions

The U.S. and California Clean Air Acts

Tampering and Altering

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.

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 Honda engine emissions within the emission standards.

Additionally, Honda fuel systems utilize components and control

technologies to reduce evaporative emissions.

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 systems.

Altering or defeating the governor linkage or speed-adjusting

mechanism to cause the engine to operate outside its design

parameters.
