2. Air-blast injection - Wikipedia

   en.wikipedia.org/wiki/Air-blast_injection

   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 ...

3. 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 ).

4. Unit injector - Wikipedia

   en.wikipedia.org/wiki/Unit_injector

   Early Lucas electronic diesel unit injector. 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.

5. Injection pump - Wikipedia

   en.wikipedia.org/wiki/Injection_pump

   Injection pump for a 12-cylinder diesel engine. An injection pump is the device that pumps fuel into the cylinders of a diesel engine.Traditionally, the injection pump was driven indirectly from the crankshaft by gears, chains or a toothed belt (often the timing belt) that also drives the camshaft.

6. Common rail - Wikipedia

   en.wikipedia.org/wiki/Common_rail

   Diesel fuel injector as installed in a MAN V8 Diesel engine. Common rail direct fuel injection is a direct fuel injection system built around a high-pressure (over 2,000 bar or 200 MPa or 29,000 psi) fuel rail feeding solenoid valves, as opposed to a low-pressure fuel pump feeding unit injectors (or pump nozzles).

7. Electronically controlled unit injector - Wikipedia

   en.wikipedia.org/wiki/Electronically_controlled...

   Partway through the pump stroke, the solenoid is energized, which closes the spill valve. The fuel is forced into the cylinder through the spray tip. Pressure reduction phase Toward the end of the pump stroke, the spill valve is re-opened, allowing the fuel to recirculate again and ending the injection phase.
