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.
