If the car's own vapor recovery system is working properly, then the Stage II nozzle will only be vacuuming normal fresh air and depositing that into the gas station's underground fuel storage tanks. That ends up causing evaporation of fuel vapors into the atmosphere, because too much pressure builds up in those fuel storage tanks.
A fuel tank (also called a petrol tank or gas tank) is a safe container for flammable fluids, often gasoline or diesel fuel. Though any storage tank for fuel may be so called, the term is typically applied to part of an engine system in which the fuel is stored and propelled ( fuel pump ) or released (pressurized gas) into an engine .
In a typical system, vapors from the fuel tank and carburetor bowl vent (on carbureted vehicles) are ducted to canisters containing activated carbon. The vapors are adsorbed within the canister, and during certain engine operational modes fresh air is drawn through the canister, pulling the vapor into the engine, where it burns.
LPG Horton sphere tanks at a Repsol Butano facility in Gijón, Spain. In a refinery or gas plant, LPG must be stored in pressure vessels. These containers are either cylindrical and horizontal (sometimes referred to as bullet tanks) or spherical (of the Horton sphere type). Typically, these vessels are designed and manufactured according to ...
Since 2011, Holden's Commodore range (sedan, wagon and ute) has been offered as a dedicated LPG vehicle, with an aluminium fuel tank in place of the petrol tank. Petrol engined cars, trucks and buses which have not been fitted with LPG/autogas systems by the manufacturers can usually accept third party systems to enable them to use either LPG ...
There were also some mechanical updates: the gear ratios of the five-speed transmission were revised for improved fuel economy, brakes now have rear vented discs instead of drums, and the fuel tank size is now 20.5 US gallons (on FWD) or 16.6 US gallons (on AWD), instead of the previous 17-US-gallon size on both models.
In the U.S., every plumbing fixture must also be coupled to the system's vent piping. [1] Without a vent, negative pressure can slow the flow of water leaving the system, resulting in clogs, or cause siphonage to empty a trap. The high point of the vent system (the top of its "soil stack") must be open to the exterior at atmospheric pressure.
Traditionally, the oil tank was a remote item, but some late-model BSAs, and the Meriden Triumphs, used "oil-in-the-frame" designs. The Triumph Rocket 3, an inline three-cylinder, water-cooled, DOHC engine. The Yamaha TRX850 270-degree parallel twin motorcycle has a dry-sump engine. Its oil reservoir is not remote, but integral to the engine ...
