Honda CR-V: Emissions Controls
The burning of gasoline in your
vehicle’s engine 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
to smog creation, but it is a
poisonous gas.
