  2. Diesel exhaust fluid - Wikipedia

    en.wikipedia.org/wiki/Diesel_exhaust_fluid

    The isocyanic acid reacts with the water vapor and hydrolyses to carbon dioxide and ammonia: HNCO + H 2 O → CO 2 + NH 3. Overall, thus far: (NH 2) 2 CO + H 2 O → 2 NH 3 + CO 2. Ammonia, in the presence of oxygen and a catalyst, reduces two different nitrogen oxides: [14] 4 NO + 4 NH 3 + O 2 → 4 N 2 + 6 H 2 O ("standard SCR") and 6 NO 2 ...

  3. Vapor recovery - Wikipedia

    en.wikipedia.org/wiki/Vapor_recovery

    Vapor (or vapour) recovery is the process of collecting the vapors of gasoline and other fuels, so that they do not escape into the atmosphere. This is often done (and sometimes required by law) at filling stations , to reduce noxious and potentially explosive fumes and pollution.

    en.wikipedia.org/wiki/Vehicle_emissions_control

    Fuel vapor storage canister for a Peugeot 205 Evaporative emissions are the result of gasoline vapors escaping from the vehicle's fuel system. Since 1971, all U.S. vehicles have had fully sealed fuel systems that do not vent directly to the atmosphere; mandates for systems of this type appeared contemporaneously in other jurisdictions.

  6. Onboard refueling vapor recovery - Wikipedia

    en.wikipedia.org/wiki/Onboard_refueling_vapor...

    An onboard refueling vapor recovery system (ORVR) is a vehicle fuel-vapor emission control system. It captures potentially harmful volatile organic compounds (VOCs) during refueling. [ 1 ] Without such a system, fuel vapors trapped inside gas tanks would be released into the atmosphere, each time the vehicle was refueled.

  7. Exhaust gas - Wikipedia

    en.wikipedia.org/wiki/Exhaust_gas

    The largest part of most combustion gas is nitrogen (N 2), water vapor (H 2 O) (except with pure-carbon fuels), and carbon dioxide (CO 2) (except for fuels without carbon); these are not toxic or noxious (although water vapor and carbon dioxide are greenhouse gases that contribute to climate change).
