2. Anti-dribble valve - Wikipedia

   en.wikipedia.org/wiki/Anti-dribble_valve

   The anti dribble function or 'pressure pipe release' [5] is achieved by not only stopping fuel flow after the main delivery phase, but also by lowering the pressure in the pipe at this point. Together with the pop valve in the fuel injector, this ensures that fuel flow stops abruptly when it needs to.

3. Fuel injection - Wikipedia

   en.wikipedia.org/wiki/Fuel_injection

   The term fuel injection is vague and comprises various distinct systems with fundamentally different functional principles. The only thing all fuel injection systems have in common is the absence of carburetion. There are two main functional principles of mixture formation systems for internal combustion engines: internal and external.

4. Blowoff valve - Wikipedia

   en.wikipedia.org/wiki/Blowoff_valve

   In the case where an airflow sensor is present upstream from the blowoff valve and the blowoff valve vents to atmosphere, the fuel injection system is unaware that some of the intake air has been vented instead of going into the cylinders. This volume of vented air is no longer relevant to the engine, however it is still included in the ...

5. Jetronic - Wikipedia

   en.wikipedia.org/wiki/Jetronic

   Fuel is pumped from the tank to a large control valve called a fuel distributor, which divides the single fuel supply line from the tank into smaller lines, one for each injector. The fuel distributor is mounted atop a control vane through which all intake air must pass, and the system works by varying fuel volume supplied to the injectors ...

6. Common rail - Wikipedia

   en.wikipedia.org/wiki/Common_rail

   Common rail fuel system on a Volvo truck engine. In 1916 Vickers pioneered the use of mechanical common rail systems in G-class submarine engines. For every 90° of rotation, four plunger pumps allowed a constant injection pressure of 3,000 pounds per square inch (210 bar; 21 MPa), with fuel delivery to individual cylinders being shut off by valves in the injector lines. [1]

7. Air-blast injection - Wikipedia

   en.wikipedia.org/wiki/Air-blast_injection

   Before the invention of precombustion chamber injection, air-blast injection was the only way a properly working internal air fuel mixture system could be built, required for a Diesel engine. During the 1920s, [ 2 ] air-blast injection was rendered obsolete by superior injection system designs that allowed much smaller but more powerful engines ...

   The extended grounding of some Boeing 737 Max jetliners is adding to pressure on Boeing and the subcontractor that made the fuselage and installed a panel that blew out leaving a gaping hole in an ...

9. Unit injector - Wikipedia

   en.wikipedia.org/wiki/Unit_injector

   The pump element is still on the way down, the solenoid is now energised and the fuel line is immediately closed. The fuel cannot pass back into the return duct, and is now compressed by the plunger until pressure exceeds specific “opening” pressure, and the injector nozzle needle lifts, allowing fuel to be injected into the combustion ...
