  2. Vapor lock - Wikipedia

    en.wikipedia.org/wiki/Vapor_lock

    Moving the fuel pump to the interior of the tank helps prevent vapor lock since the entire fuel-delivery system is under positive pressure and the fuel pump runs cooler than it would be if it is located in the engine compartment. This is the primary reason that vapor lock is rare in modern fuel systems. For the same reason, some carbureted ...

  3. Fuel starvation - Wikipedia

    en.wikipedia.org/wiki/Fuel_starvation

    British Airways Flight 38 crash-landed at London Heathrow in 2008 after its fuel lines became clogged with ice crystals.. In an internal combustion engine, fuel starvation is the failure of the fuel system to supply sufficient fuel to allow the engine to run properly, for example due to blockage, vapor lock, contamination by water, malfunction of the fuel pump or incorrect operation, leading ...

  4. Flooded engine - Wikipedia

    en.wikipedia.org/wiki/Flooded_engine

    Some fuel injection computers interpret "pumping" the throttle to indicate a flooded engine, and alter the fuel-air mixture accordingly. In a carbureted engine equipped with an accelerator pump (which advances fuel flow to match air ingestion under rapid throttle acceleration), "pumping" the throttle will force excess fuel into the engine ...

  5. Dieseling - Wikipedia

    en.wikipedia.org/wiki/Dieseling

    Fuel demand is low at idle and there is more than enough manifold vacuum to draw sufficient fuel for combustion, even if the fuel pump is switched off. Gasoline engines that are much smaller than the typical automotive engine are usually carbureted for economic and engineering reasons. Dieseling can occur in such engines.

  6. Fuel pump - Wikipedia

    en.wikipedia.org/wiki/Fuel_pump

    The reasons that the fuel pump is typically located in the fuel tank are: By submerging the pump in fuel at the bottom of the tank, the pump is cooled by the surrounding fuel; Liquid fuel by itself (i.e. without oxygen present) isn't flammable, therefore surrounding the fuel pump by fuel reduces the risk of fire

  7. Diesel engine runaway - Wikipedia

    en.wikipedia.org/wiki/Diesel_engine_runaway

    Diesel engine runaway is an occurrence in diesel engines, in which the engine draws excessive fuel from an unintended source and overspeeds at higher RPMs, producing up to ten times the engine's rated output resulting in a catastrophic mechanical failure due to a lack of lubrication. [1]

  8. Turbine engine failure - Wikipedia

    en.wikipedia.org/wiki/Turbine_engine_failure

    A turbine engine failure occurs when a gas turbine engine unexpectedly stops producing power due to a malfunction other than fuel exhaustion. It often applies for aircraft , but other turbine engines can also fail, such as ground-based turbines used in power plants or combined diesel and gas vessels and vehicles.

  9. Ford Power Stroke engine - Wikipedia

    en.wikipedia.org/wiki/Ford_Power_Stroke_engine

    It ran a high pressure oil pump (HPOP) to create the necessary oil pressure to fire the fuel injectors. This generation of Power Stroke utilizes an HPOP with a 15° swash plate angle. The 1995-1997 trucks use a two-stage cam-driven fuel pump, whereas the 1999-2003 trucks use a frame rail mounted electric fuel pump.
