Tampering and Altering
The combustion process producescarbon monoxide, oxides of
nitrogen, and hydrocarbons. Controlof hydrocarbons and oxides of
nitrogen is very important because, underc ertainconditions, they
react to form photochemicalsmog when subjected to sunlight. Carbon
monoxide does not react in the same way, but it is toxic.
Honda uses lean carburetor settings and other systemsto reduce the
emissions of carbon monoxide, oxides of nitrogen, and hydrocarbons.
EPA and California regulations require all manufacturers to furnish
written instructions describing the operationand 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 with ora lteringthe 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.
