Emissions Controls
The burning of gasoline in your car'sengine 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. 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 192.
* In Canada, Acura vehicles comply
with the Canadian Motor Vehicle Safety Standards (CMVSS) for
Emissions valid at the time they are
manufactured.
Crankcase Emissions Control
System
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.
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 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.
Onboard Refueling Vapor
Recovery
The Onboard Refueling Vapor Recovery (ORVR) system captures
the fuel vapors during refueling. The
vapors are adsorbed in a canister filled with activated carbon. Whiledriving, the fuel vapors are drawn
into the engine and burned off.
