catalytic converter HONDA S2000 2000 1.G Owners Manual

Always use the parking brake when
you park your car.
The indicator on
the instrument panel shows that the
parking brake is not fully released; it
does not indicate that the parking
brake is firmly set. Make sure the
parking brake is set firmly or your
car may roll
if it is parked on an
incline. If
the car is facing uphill, turn the
front wheels away from the curb and
put
the transmission in first gear.
If the car is facing downhill, turn the
front wheels toward the curb and put
the transmission
in reverse gear.
Make sure the parking brake is fully
released before driving away.
Driving with the parking brake
partially set can overheat or damage
the rear brakes.
Parking
Parking Tips
• Make sure the convertible top and
the windows are closed.
• Turn off the lights.
• Place any packages, valuables, etc.,
in the trunk or take them with you.
• Lock the doors with the key or the
remote transmitter.
• Never park over dry leaves, tall
grass, or other flammable
materials.
The three way catalytic
converter gets very hot, and could
cause these materials to catch on
fire.

Technical Information 241

If you are planning to take your
Honda outside the
U.S. or Canada,
contact the tourist bureaus in the
areas you
will be traveling in to find
out about the availability of unleaded
gasoline with the proper octane
rating.
If unleaded gasoline is not available,
be aware
that using leaded gasoline
in your Honda will affect perfor­
mance and fuel mileage, and damage
its emissions controls.
It will no
longer comply with
U.S. and
Canadian emissions regulations, and
will be illegal to operate in North
America.
To bring your car back into
compliance will require
the replace­
ment of several components, such as
the oxygen sensors and the three
way catalytic converter.
These re­
placements are not covered under
warranty.

Exhaust Emissions Controls
The exhaust emissions controls
include four systems:
PGM-FI,
Ignition Timing Control, Secondary
Air Injection System and
Three Way
Catalytic Converter. These four
systems work together to control the
engine's combustion and minimize
the amount of
HC, CO, and NOx that
comes out the tailpipe.
The exhaust
emissions control systems are
separate from the crankcase and
evaporative emissions control
systems.
PGM-FI System
The PGM-FI System uses sequential
multiport fuel injection.
It has three subsystems: Air Intake,
Engine
Control, and Fuel Control.
The Engine Control Module (ECM)
uses various sensors to determine
how much air is going into the
engine.
It then controls how much
fuel to inject under all operating
conditions.
Ignition Timing Control System
This system constantly adjusts the
ignition timing, reducing the amount
of
HC, CO and NOx produced.
Secondazy Air Injection System
During engine warm-up, air is
pumped into the exhaust to reduce
emissions when
the engine is cold.
Three Way Catalytic Converter
The three way catalytic converter is
in the exhaust system. Through
chemical reactions, it converts
HC,
CO, and NOx in the engine's exhaust
to carbon dioxide
(COz), dinitrogen
(Nz), and water vapor.
Emissions Controls
Replacement Parts
The emissions control systems are
designed and certified to work
to­
gether in reducing emissions to
levels that comply with the
Clean Air
Act. To make sure the emissions
remain
low, you should use only new
Genuine Honda replacement parts or
their equivalent for repairs. Using
lower quality parts may increase the
emissions from your car.
The emissions control systems are
covered by warranties separate from
the rest of your car. Read your
warranty manual for more informa­
tion.
Technical Information 251

Three Way Catalytic Converter
The three way catalytic converter
contains precious metals
that serve
as catalysts, promoting chemical
reactions to convert the exhaust
gasses without affecting the metals.
The catalytic converter is referred to
as a three-way catalyst, since it acts
on
HC, CO, and NOx. A replacement
unit must be an original Honda part
or its equivalent.
The three way catalytic converter
must operate at a high temperature
for the chemical reactions to take
place.
It can set on fire any com­
bustible materials that come near
it.
Park your car away from high grass,
dry leaves, or other flammables.
252 Technical Information
A defective three way catalytic
converter contributes to air pollution,
and can impair your engine's per­
formance. Follow these guidelines to
protect your car's
three way catalytic
converter.
• Always use unleaded gasoline.
Even a small amount of leaded
gasoline can contaminate the
catalyst metals, making the three
way catalytic converter ineffective.
• Keep the engine tuned-up.
• Have your car diagnosed and
repaired
if it is misfiring, back­
firing, stalling, or otherwise not
running properly.
