An onboard refueling vapor recovery system (ORVR) is a vehicle fuel vapor emission control system that captures volatile organic compounds (VOC, potentially harmful vapors) during refueling. [1] [page needed] There are two types of vehicle fuel vapor emission control systems: the ORVR, and the Stage II vapor recovery system. [2]
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.
Recovery is by the slow release of bound CO and the body's production of new hemoglobin – a healing process – so full recovery from moderate to severe [but nonfatal] CO poisoning takes hours or days. Removing a person from a CO-poisoned atmosphere to fresh air stops the injury but does not yield prompt recovery, unlike the case where a ...

A vapor recovery system may be employed at the exhaust pipe. This system collects the vapors, liquefies them and releases them back into the lowest grade fuel tank available. The forecourt is the part of a filling station where vehicles are refueled.
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.
