Gas nozzle with 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.
As in a UI, the injector is connected to common banks of fuel supply and fuel return. Fuel is always circulating within the EUI as two of its functions, other than injection for combustion, are injector lubrication and injector cooling. Connections on UIs are by formed steel tubes. Connections on EUIs are by stainless steel-reinforced hoses.
The gas expands adiabatically with low losses and hence high efficiency. The gas accelerates to a final exit velocity which depends on the pressure and temperature at entry to the nozzle, the ambient pressure it exhausts to (unless the flow is choked), and the efficiency of the expansion. [5]
A gasoline pump or fuel dispenser is a machine at a filling station that is used to pump gasoline (petrol), diesel, or other types of liquid fuel into vehicles. Gasoline pumps are also known as bowsers or petrol bowsers (in Australia and South Africa ), [ 2 ] [ 3 ] petrol pumps (in Commonwealth countries), or gas pumps (in North America ).
A fast fuel system (FFS) allows speedy and safe refueling. FFS are available for applications including mining, heavy construction, buses and railroad. Most larger earthmoving and mining vehicles with diesel fuel tanks over 150 US gallons (570 L) are equipped with FFS. They use an automatic shut-off nozzle, receiver and level control device.
A unit injector (UI) is a high-pressure integrated direct fuel injection system for diesel engines, combining the injector nozzle and the injection pump in a single component. The plunger pump used is usually driven by a shared camshaft .

Unlike modern designs, air-blast injected Diesel engines do not have an injection pump. A simple low-pressure fuel-feed-pump is used instead to supply the injection nozzle with fuel. At injection, a blast of compressed air presses the fuel into the combustion chamber, hence the name air-blast injection. The compressed air comes from compressed ...
