  2. Oil pump (internal combustion engine) - Wikipedia

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

    Gerotor type oil pump from a scooter engine. The oil pump is an internal combustion engine part that circulates engine oil under pressure to the rotating bearings, the sliding pistons and the camshaft of the engine. This lubricates the bearings, allows the use of higher-capacity fluid bearings and also assists in cooling the engine.

  3. 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.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 and ...

  4. Aircraft engine starting - Wikipedia

    en.wikipedia.org/wiki/Aircraft_engine_starting

    The Hucks starter (invented by Bentfield Hucks during WWI) is a mechanical replacement for the ground crew. Based on a vehicle chassis the device uses a clutch driven shaft to turn the propeller, disengaging as the engine starts. A Hucks starter is used regularly at the Shuttleworth Collection for starting period aircraft.

  5. Break-in (mechanical run-in) - Wikipedia

    en.wikipedia.org/wiki/Break-in_(mechanical_run-in)

    Break-in or breaking in, also known as run-in or running in, is the procedure of conditioning a new piece of equipment by giving it an initial period of running, usually under light load, but sometimes under heavy load or normal load. It is generally a process of moving parts wearing against each other to produce the last small bit of size and ...

  6. Turndown ratio - Wikipedia

    en.wikipedia.org/wiki/Turndown_ratio

    Turndown ratio refers to the width of the operational range of a device, and is defined as the ratio of the maximum capacity to minimum capacity. For example, a device with a maximum output of 10 units and a minimum output of 2 units has a turndown ratio of 5. The term is commonly used with measurement devices and combustion plant like boilers ...

  7. Pipeline pre-commissioning - Wikipedia

    en.wikipedia.org/wiki/Pipeline_pre-commissioning

    Pre-commissioning [1] is the series of processes carried out on the pipeline before the final product is introduced. The process during which the pipeline is made "live" i.e. the product is put in the pipeline, is called pipeline commissioning or start-up. Despite being seen as an offshoot, or minor part of the business for the larger oil ...

  8. Splash lubrication - Wikipedia

    en.wikipedia.org/wiki/Splash_lubrication

    The oil droplets then pass through drillings to the bearings and thereby lubricate the moving parts. [3] Provided that the bearing is a ball bearing or a roller bearing , splash lubrication would usually be sufficient; however, plain bearings typically need a pressure feed to maintain the oil film, loss of which leads to overheating and seizure.

  9. Oil well control - Wikipedia

    en.wikipedia.org/wiki/Oil_well_control

    Oil well control is the management of the dangerous effects caused by the unexpected release of formation fluid, such as natural gas and/or crude oil, upon surface equipment of oil or gas drilling rigs and escaping into the atmosphere. Technically, oil well control involves preventing the formation gas or fluid (hydrocarbons), usually referred ...
