  2. Vapor recovery - Wikipedia

    en.wikipedia.org/wiki/Vapor_recovery

    In 1975 the Vapor Recovery Gasoline Nozzle was an improvement on the idea of the original gasoline nozzle delivery system. The improved idea was the brain child of Mark Maine of San Diego, California, where Mark was a gas station attendant at a corporate owned and operated Chevron U.S.A. service station.

  3. Nozzle - Wikipedia

    en.wikipedia.org/wiki/Nozzle

    A nozzle is often a pipe or tube of varying cross sectional area, and it can be used to direct or modify the flow of a fluid (liquid or gas). Nozzles are frequently used to control the rate of flow, speed, direction, mass, shape, and/or the pressure of the stream that emerges from them.

  4. Propelling nozzle - Wikipedia

    en.wikipedia.org/wiki/Propelling_nozzle

    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]

  5. Components of jet engines - Wikipedia

    en.wikipedia.org/wiki/Components_of_jet_engines

    The propelling nozzle converts a gas turbine or gas generator into a jet engine. Power available in the gas turbine exhaust is converted into a high speed propelling jet by the nozzle. The power is defined by typical gauge pressure and temperature values for a turbojet of 20 psi (140 kPa) and 1,000 °F (538 °C). [18]

  6. Gasoline pump - Wikipedia

    en.wikipedia.org/wiki/Gasoline_pump

    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 ).

  7. Rocket engine nozzle - Wikipedia

    en.wikipedia.org/wiki/Rocket_engine_nozzle

    The gas flow rate is constant (i.e., steady) during the period of the propellant burn. The gas flow is non-turbulent and axisymmetric from gas inlet to exhaust gas exit (i.e., along the nozzle's axis of symmetry). The flow is compressible as the fluid is a gas. As the combustion gas enters the rocket nozzle, it is traveling at subsonic velocities.

  9. Gasoline direct injection - Wikipedia

    en.wikipedia.org/wiki/Gasoline_direct_injection

    In engines with wall-guided injection, the distance between spark plug and injection nozzle is relatively high. In order to get the fuel close to the spark plug, it is sprayed against a swirl cavity on top of the piston (as seen in the picture of the Ford EcoBoost engine on the right), which guides the fuel towards the spark plug.
