1996 HONDA ODYSSEY catalytic converter

Gasoline

The following are the EPA-approved percentages of oxygenates:
ETHANOL (ethyl or grain alcohol)
You may use gasoline containing up to 10% ethanol by volume. Gasoline containing ethanol may be marketed
under the name "Gasohol."
MTBE (Methyl Tertiary Butyl

Ether)

You may use gasoline containing up to 15% MTBE by volume. METHANOL (methyl or wood

alcohol)

You may use gasoline containing up to 5% methanol by volume as long asit also contains cosolvents andcorrosion inhibitors to protect the
fuel system. Gasoline containing more than 5% methanol by volume
may cause starting and/or perform-ance problems. It may also damage
metal, rubber and plastic parts of
your fuel system.
If you notice any undesirableoperating symptoms, try another
service station or switch to another
brand of gasoline.
Fuel system damage or performance
problems resulting from the use of an oxygenated fuel containing morethan the percentages of oxygenates
given above are not covered under
warranty.
Driving in Foreign Countries

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 nolonger comply with U.S. andCanadian 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 sensor and the three way catalytic converter. These replace-
ments are not covered under
warranty.

Emission Controls

Exhaust Emission Controls

The exhaust emission controls include four systems: PGM-FI,
Ignition Timing Control, ExhaustGas Recirculation and Three Way
Catalytic Converter. These foursystems work together to control the
engine's combustion and minimize
the amount of HC, CO, and NOx that comes out the tailpipe. The exhaust
emission control systems areseparate from the crankcase and
evaporative emission 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 Powertrain Control Module (PCM) uses various sensors to
determine how much air is going
into the engine. It then controls how much fuel to inject under all operat-
ing conditions. Ignition Timing Control System
This system constantly adjusts the ignition timing, reducing the amount
of HC, CO and NOx produced.
Exhaust Gas Recirculation (EGR)
System

The Exhaust Gas Recirculation (EGR) system takes some of the
exhaust gas and routes it back into
the intake manifold. Adding exhaust gas to the air/fuel mixture reduces
the amount of NOx produced when
the fuel is burned.
Three Way Catalytic Converter
The three way catalytic converter is in the exhaust system. Throughchemical reactions, it converts HC, CO, and NOx in the engine's exhaust
to carbon dioxide (CO 2), dinitrogen

(N 2), and water vapor.
Replacement Parts

The emission 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. Usinglower quality parts may increase theemissions 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.

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 actson 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. 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 catalyticconverter.
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.
