  2. Dieseling - Wikipedia

    en.wikipedia.org/wiki/Dieseling

    Dieseling (in the sense of engine run-on, and disregarding combustible gaseous mixtures via the air intake) can also occur in diesel engines, when the piston or seals fail due to overheating, admitting engine oil into the cylinder. A structurally failing diesel engine will often accelerate when the throttle is released, even after fuel ...

  3. Engine knocking - Wikipedia

    en.wikipedia.org/wiki/Engine_knocking

    This way performance is kept at its optimum while mostly eliminating the risk of engine damage caused by knock (e.g. when running on low octane fuel). [5] An early example of this is in turbocharged Saab H engines, where a system called Automatic Performance Control was used to reduce boost pressure if it caused the engine to knock. [6]

  4. Crankshaft position sensor - Wikipedia

    en.wikipedia.org/wiki/Crankshaft_position_sensor

    A crank sensor (CKP) [1] [2] [3] is an electronic device used in an internal combustion engine, both petrol and diesel, to monitor the position or rotational speed of the crankshaft. This information is used by engine management systems to control the fuel injection or the ignition system timing and other engine parameters.

  5. Electronic Diesel Control - Wikipedia

    en.wikipedia.org/wiki/Electronic_Diesel_Control

    The mechanical fly-weight governors of inline and distributor diesel fuel injection pumps used to control fuel delivery in diesel engines under a variety of engine loads and conditions could no longer deal with the ever-increasing demands for efficiency, emission control, power and fuel consumption. These demands are now primarily fulfilled by ...

  6. Diesel engine - Wikipedia

    en.wikipedia.org/wiki/Diesel_engine

    1952 Shell Oil film showing the development of the diesel engine from 1877. The diesel engine, named after the German engineer Rudolf Diesel, is an internal combustion engine in which ignition of diesel fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is called a compression-ignition engine (CI engine).

  7. Noise and vibration on maritime vessels - Wikipedia

    en.wikipedia.org/wiki/Noise_and_vibration_on...

    When looking at diesel driven vessels, the engines induce large accelerations that travel from the foundation of the engine throughout the ship. In most compartments, this type of vibration normally manifests itself as audible noise. The problem with diesels is that, for a given size, there is a fixed amount of power generated per cylinder.

  9. Noise control - Wikipedia

    en.wikipedia.org/wiki/Noise_control

    Speed control is effective since the lowest sound emissions arise from vehicles moving smoothly at 30 to 60 kilometers per hour. Above that range, sound emissions double with every five miles per hour of speed. At the lowest speeds, braking and (engine) acceleration noise dominates.
