Emission Controls

Exhaust Emission Controls
The exhaust emission 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
emission control systems are
separate from the crankcase and
evaporative emission 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 theengine. 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

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 (CO 2), dinitrogen
(N 2), and water vapor. Replacement Parts
The emission 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 theemissions 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.

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 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 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 car diagnosed and

repaired if it is misfiring, back- firing, stalling, or otherwise not

running properly.
