Emissions Controls

The burning of gasoline in your car's engine produces several byproducts.
Some of these are carbon monoxide (CO), oxides of nitrogen (NOx) and
hydrocarbons (HC). Gasoline evaporating from the tank also
produces hydrocarbons. Controlling
the production of NOx, CO, and HC is important to the environment.
Under certain conditions of sunlightand climate, NOx and HC react to
form photochemical "smog." Carbon monoxide does not contribute tosmog creation, but it is a poisonous

gas.
The Clean Air Act

The United States Clean Air Act*
sets standards for automobile

emissions. It also requires that

automobile manufacturers explain to
owners how their emissions controls

work and what to do to maintain
them. This section summarizes how

the emissions controls work.
Scheduled maintenance is on page
224.

* In Canada, Honda vehicles comply

with the Canadian Motor Vehicle
Safety Standards (CMVSS) for

Emissions valid at the time they are

manufactured.

Crankcase Emissions Control

System

Your car has a Positive Crankcase
Ventilation System. This keeps gasses that build up in the engine'scrankcase from going into the
atmosphere. The Positive Crankcase
Ventilation valve routes them from the crankcase back to the intake
manifold. They are then drawn into
the engine and burned.
Evaporative Emissions Control

System

As gasoline evaporates in the fuel tank, an evaporative emissions
control canister filled with charcoaladsorbs the vapor. It is stored in this
canister while the engine is off. After
the engine is started and warmed up,
the vapor is drawn into the engine and burned during driving.
Onboard Refueling Vapor
Recovery
The Onboard Refueling Vapor Recovery (ORVR) system captures
the fuel vapors during refueling. The
vapors are adsorbed in a canister filled with activated carbon. While driving, the fuel vapors are drawn
into the engine and burned off.
Technical Information

Emissions Controls

Exhaust Emissions Controls
The exhaust emissions controls include three systems: PGM-FI,Ignition Timing Control and Three
Way Catalytic Converter. These three systems work together tocontrol the engine's combustion and
minimize the amount of HC, CO, and
NOx that comes out the tailpipe. The
exhaust emissions control systemsare 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) or 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 amountof HC, CO and NOx produced.
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 (CO 2), dinitrogen
(N2), and water vapor. 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 newGenuine 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

Three Way Catalytic Converter

The three way catalytic converter contains precious metals that serveas 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. 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.

State Emissions Testing

Testing of Readiness Codes
If you take your vehicle for a state
emissions test shortly after the
battery has been disconnected or
gone dead, it may not pass the test.
This is because of certain "readiness codes" that must be set in the on-
board diagnostics for the emissionssystems. These codes are erased
when the battery is disconnected, and set again only after several days
of driving under a variety of
conditions. If the testing facility determines that
the readiness codes are not set, you
will be requested to return at a later date to complete the test. If you must
get the vehicle re-tested within the next two or three days, you can
condition the vehicle for re-testing
by doing the following.
Make sure the gas tank is nearly,
but not completely, full (around 3/4).
Make sure the vehicle has been
parked with the engine off for 8
hours or more.
Make sure the ambient
temperature is between 20° and
95°
F.
Without touching the accelerator
pedal, start the engine and let it
idle for 20 seconds.
Keep the vehicle in Park (automatic transmission) or
Neutral (manual transmission). Increase the engine speed to 2,000
rpm and hold it there until the
temperature gauge rises to at least 1/4 of the scale (approximately 3

minutes).
