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 of

sunlight 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

Crankcase Emissions Control

System

Your vehicle has a Positive

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

188.

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 then

drawn into the engine and burned.

* In Canada, Honda vehicles comply

with the Canadian Motor Vehicle

Safety Standards (CMVSS) for

Emissions valid at the time they are

manufactured.

Evaporative Emissions Control

System

As gasoline evaporates in the fuel

tank, an evaporative emissions

control canister filled with charcoal

adsorbs 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.

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 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.

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 vehicle.

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.

The emissions control systems are

covered by warranties separate from

the rest of your vehicle. Read your

warranty manual for more informa-

tion.

Ignition Timing Control System

This system constantly adjusts the

ignition timing, reducing the amount

of 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

(N ), and water vapor.

Three Way Catalytic Converter

Keep the engine tuned-up.

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.

Have your vehicle diagnosed and

repaired if it is misfiring, back-

firing, stalling, or otherwise not

running properly.

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.

THREE WAY CATALYTIC CONVERTER

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.
