2. Oil pump (internal combustion engine) - Wikipedia

   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.

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. [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 ...

4. Hydraulic tappet - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_tappet

   Oil under constant pressure is supplied to the lifter via an oil channel, through a small hole in the lifter body. When the engine valve is closed (lifter in a neutral position), the lifter is free to fill with oil. As the camshaft lobe enters the lift phase of its travel, it compresses the lifter piston, and a check valve shuts the oil inlet ...

5. Pressure switch - Wikipedia

   en.wikipedia.org/wiki/Pressure_switch

   Hydraulic pressure switches have various uses in automobiles, for example, to warn if the engine's oil pressure falls below a safe level, or to control automatic transmission torque converter lock-up. Prior to the 1960s, a pressure switch was used in the hydraulic braking circuit to control power to the brake lights; more recent automobiles use ...

6. Crankcase - Wikipedia

   en.wikipedia.org/wiki/Crankcase

   Otherwise, the high-speed rotation of the crankshaft would cause the oil to froth, making it difficult for the oil pump to move the oil, which can starve the engine of lubrication. [5] Oil from the sump may splash onto the crankshaft due to g-forces or bumpy roads, which is referred to as windage .

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 extra fuel from an unintended source and overspeeds at higher and higher RPM, producing up to ten times the engine's rated output until destroyed by mechanical failure or bearing seizure due to a lack of lubrication. [1]

   U.S. regulators are warning airlines to limit the use of an anti-icing system on Boeing 737 Max jets in dry air to avoid overheating engine-housing parts, which could cause them to break away from ...

9. Motor oil - Wikipedia

   en.wikipedia.org/wiki/Motor_oil

   An oil pump, a vane or gear pump powered by the engine, pumps the oil throughout the engine, including the oil filter. Oil filters can be a full flow or bypass type. In the crankcase of a vehicle engine, motor oil lubricates rotating or sliding surfaces between the crankshaft journal bearings (main bearings and big-end bearings) and rods ...
