Emission
s Control s

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 sunlight and climate, NOx and HC react to
form photochemical "smog." Carbon monoxide does not contribute tosmog creation, but it is a poisonous

gas.
Th
e Clea n Ai r Ac t
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 172.
* In Canada, Honda vehicles comply
with the Canadian Motor Vehicle Safety Standards (CMVSS) for
Emissions valid at the time they are
manufactured.
Crankcas e Emission s Contro l
Syste m
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.
Evaporativ e Emission s Contro l
Syste m
As gasoline evaporates in the fuel tank, an evaporative emissionscontrol 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 engineand burned during driving.
Onboar d Refuelin g Vapo r
Recover y
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.

Emission
s Control s

Exhaus t Emission s Control s
The exhaust emissions controls include four systems: PGM-FI,
Ignition Timing Control, Exhaust
Gas Recirculation and Three WayCatalytic 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 exhaustemissions 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.
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. Replacemen
t Part s
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.

Thre
e Wa y Catalyti c Converte r
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. 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.
