  2. Dieseling - Wikipedia

    en.wikipedia.org/wiki/Dieseling

    The vast majority of vehicles manufactured after 1987 are fuel-injected: the injectors and high-pressure fuel pump immediately cease supplying fuel to the cylinders when the ignition is switched off. If the injector is damaged or dirty, a small amount of fuel can enter the chamber and be ignited, causing a sputter or two after the engine is ...

  3. Oil pump (internal combustion engine) - Wikipedia

    en.wikipedia.org/wiki/Oil_pump_(internal...

    [c] These are supplementary pumps and do not replace the main, mechanical, oil pump. Electric pump as a main engine pump again will require big electric motors and it may be simply cheaper to drive directly from the engine. For e.g. BMW S65 engine's oil pump delivers ca. 45 LPM (Litres Per Minute) of oil at 5.5 bar pressure. [5]

  4. Diesel engine runaway - Wikipedia

    en.wikipedia.org/wiki/Diesel_engine_runaway

    Engines fitted with a decompressor can also be stopped by operating the decompressor, and in a vehicle with a manual transmission it is sometimes possible to stop the engine by engaging a high gear (i.e. 4th, 5th, 6th etc.), with foot brake and parking brake fully applied, and quickly letting out the clutch to slow the engine RPM to a stop ...

  5. Flooded engine - Wikipedia

    en.wikipedia.org/wiki/Flooded_engine

    A severe form of engine flooding occurs when excessive liquid fuel enters the combustion chamber. This reduces the dead volume of the combustion chamber and thus places a heavy load on the starter motor, such that it fails to turn the engine. Damage (due to excessive compression and even dilution of the lubricating oil with fuel) can also occur.

  6. Crankcase dilution - Wikipedia

    en.wikipedia.org/wiki/Crankcase_dilution

    Crankcase dilution occurs when the fuel oil from the engine gets into the lube oil of the engine. This can be caused by the walls being wetted due to the fuel condensing in the cylinder. If the engine is cold, or there is an excess amount of cooling around the cylinder, [ 1 ] the fuel oil will condense and have a higher chance to end up in the ...

  7. Four-stroking - Wikipedia

    en.wikipedia.org/wiki/Four-stroking

    Four-stroking is a condition of two-stroke engines where combustion occurs every four strokes or more, rather than every two. Though normal in some instances at idle, extremely high engine speeds, and when letting off the throttle, such firing is uneven, noisy and may, in cases of malfunction, damage the engine if allowed to continue unabated.

  9. Vapor lock - Wikipedia

    en.wikipedia.org/wiki/Vapor_lock

    Vapor lock is a problem caused by liquid fuel changing state to vapor while still in the fuel delivery system of gasoline-fueled internal combustion engines.This disrupts the operation of the fuel pump, causing loss of feed pressure to the carburetor or fuel injection system, resulting in transient loss of power or complete stalling.
