Identification Numbers

Your vehicle has several identifying numbers located in various places.
The Vehicle Identification Number (VIN) is the 17-digit number your
Honda dealer uses to register your
vehicle for warranty purposes. It is also necessary for licensing and
insuring your vehicle. The easiest
place to find the VIN is on a plate
fastened to the top of the dashboard.
You can see it by looking through the windshield on the driver's side. Itis also on the Certification label at-
tached to the driver's doorjamb, and is stamped on the engine com-
partment bulkhead. The VIN is also
provided in bar code on the Certification label.

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
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 164.
* In Canada, Honda vehicles comply
with the Canadian Motor Vehicle Safety Standards (CMVSS) forEmissions 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 four systems: PGM-FI,
Ignition Timing Control, ExhaustGas Recirculation and Three Way
Catalytic 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 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.
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. Through
chemical reactions, it converts HC,CO, and NOx in the engine's exhaust
to carbon dioxide (C02), 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 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 vehicle away from high
grass, dry leaves, or other flamma-
bles.
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. Keep the engine tuned-up. Have your vehicle diagnosed and
repaired if it is misfiring, back-
firing, stalling, or otherwise not
running properly.
