Emissions Controls

The burning of gasoline in your
vehicle's engine produces several by- products. Some of these are carbonmonoxide (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 224.
* In Canada, Honda vehicles comply
with the Canadian Motor Vehicle Safety Standards (CMVSS) for
Emissions 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 then
drawn into the engine and burned.
Evaporative Emissions Control

System

As gasoline evaporates in the fuel tank, an evaporative emissionscontrol canister filled with charcoal
adsorbs the vapor. It is stored in thiscanister 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 areseparate 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 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. 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 (CO2), dinitrogen (N 2), 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 new Genuine 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.
