  2. Oil pressure - Wikipedia

    en.wikipedia.org/wiki/Oil_pressure

    Murphy oil pressure gauges with switches that activate on low pressure. Oil pressure is an important factor in the longevity of most internal combustion engines. [1] With a forced lubrication system (invented by Frederick Lanchester), oil is picked up by a positive displacement oil pump and forced through oil galleries (passageways) into bearings, such as the main bearings, big end bearings ...

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

    Indications of low oil pressure may be that the warning light is on, a low pressure reading on the gauge, or clattering/clinking noises from the engine. Low oil pressure is a problem that must be addressed immediately to prevent serious damage. The leading cause of low oil pressure in an engine is wear on the engine's vital parts.

  4. Aircraft engine starting - Wikipedia

    en.wikipedia.org/wiki/Aircraft_engine_starting

    In cold ambient conditions the friction caused by viscous engine oil causes a high load on the starting system. Another problem is the reluctance of the fuel to vaporise and combust at low temperatures. Oil dilution systems were developed (mixing fuel with the engine oil), [8] and engine pre-heaters were used (including lighting fires under the ...

  5. Turbine engine failure - Wikipedia

    en.wikipedia.org/wiki/Turbine_engine_failure

    Baikal Airlines Flight 130: a starter of engine No. 2 on a Tu-154 heading from Irkutsk to Domodedovo, Moscow in 1994, failed to stop after engine startup and continued to operate at over 40,000 rpm with open bleed valves from engines, which caused an uncontained failure of the starter. A detached turbine disk damaged fuel and oil supply lines ...

  6. Starting fluid - Wikipedia

    en.wikipedia.org/wiki/Starting_fluid

    Starting fluid is not recommended for regular use with some two-stroke engines because it does not possess lubricating qualities by itself. Lubrication for two-stroke engines is achieved using oil that is either mixed into the fuel by the user or injected automatically into the fuel supply; engines requiring premixed fuel that are run solely on starting fluid do not receive an adequate supply ...

  7. Chevrolet 2300 engine - Wikipedia

    en.wikipedia.org/wiki/Chevrolet_2300_engine

    The engine was equipped with an oil pressure switch which grounds out the primary-ignition system should the oil pressure fall below 6 psi (0.41 bar) during operation, stopping the engine and preventing it from being restarted until the oil level was replenished or the mechanical cause of low-oil pressure was remedied.

    At 09:15, while descending through 15,000 feet (4,600 m), the low oil pressure indicator on the TriStar's number 2 engine illuminated. [2] The flight engineer noted that the oil pressure on the #2 engine was fluctuating between 15 and 25 psi ; the minimum pressure required for normal engine operation was 30 psi. [ 7 ]
