Emissions Controls

The burning of gasoline in your vehicle's engine produces several by-products. Some of these are carbon
monoxide (CO), oxides of nitrogen (NOx) and hydrocarbons (HC).
Gasoline evaporating from the tank
also produces hydrocarbons. Con-
trolling the production of NOx, CO, and HC is important to the environ-
ment. Under certain conditions ofsunlight and climate, NOx and HC
react to form photochemical "smog." Carbon monoxide does not contri-
bute to smog 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 toowners 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
142.

* 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 vehicle has a Positive Crankcase Ventilation System. This
keeps gasses that build up in the engine's crankcase from going into
the atmosphere. The Positive Crank-
case Ventilation valve routes them
from the crankcase back to the intake manifold. They are thendrawn 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.

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)/ Powertrain Control Module (PCM)/
Transmission Control Module (TCM-HX model only) 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 amountof HC, CO and NOx produced.
Exhaust Gas Recirculation (EGR)
System
Only on HX model

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. Through
chemical reactions, it converts HC,CO, and NOx in the engine's exhaust
to carbon dioxide (Co2), 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 vehicle.

The emissions control systems are covered by warranties separate from

the rest of your vehicle. 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 vehicle away from high
grass, dry leaves, or other flamma-

bles.
(U.S.: EX, Canada: Si)

A defective three way catalytic converter contributes to air pollution,
and can impair your engine's per-
formance. Follow these guidelines to protect your vehicle'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.
(U.S.: DX, HX, Canada: DX)

Keep the engine tuned-up.
Have your vehicle diagnosed and
repaired if it is misfiring, back-
firing, stalling, or otherwise not running properly.
