EMISSION CONTROL SYSTEM

SOURCE OF EXHAUST EMISSIONS

The combustion process produces carbon monoxide(CO),
oxides of nitrogen(NOx)and hydrocarbons(HC). 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.

EXHAUST EMISSION CONTROL SYSTEM

The exhaust emission control system includes a PGM-F
system and oxygen sensor.
No adjustments to this system should be made although
periodic inspection of the components is recommended.
The exhaust emission control system is separate from the
crankcase emission control system.
