Honda CR-V: Emissions Controls

Honda CR-V (2006–2011) Owner's Manual / Technical Information / 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.
