  2. Dry sump - Wikipedia

    en.wikipedia.org/wiki/Dry_sump

    However, narrower engines can be mounted lower and ideally should use dry-sump lubrication. Several motorcycle models that use dry-sumps include; The classic British parallel twin motorcycles, such as BSA, Triumph and Norton, all used dry-sump lubrication. Traditionally, the oil tank was a remote item, but some late-model BSAs, and the Meriden ...

  3. Splash lubrication - Wikipedia

    en.wikipedia.org/wiki/Splash_lubrication

    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. The splash lubrication system has simplicity, reliability, and cheapness within its virtues. [4]

  4. Automatic lubrication system - Wikipedia

    en.wikipedia.org/wiki/Automatic_lubrication_system

    The automatic lubrication system is connected to a control system via switchs. The control system may involve human input or may be computerised (computer numerical control or CNC). [2] [3] There are advantages of using an automatic lubrication system over a manual system. For example, there are savings in the costs of human resources. The ...

  5. Wet sump - Wikipedia

    en.wikipedia.org/wiki/Wet_sump

    In most production automobiles and motorcycles, which use a wet sump system, the oil is collected in a 3 to 10 litres (0.66 to 2.20 imp gal; 0.79 to 2.64 US gal) capacity pan at the base of the engine, known as the sump or oil pan, where it is pumped back up to the bearings by the internal oil pump.

  6. 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 ...

  7. Internal combustion engine - Wikipedia

    en.wikipedia.org/wiki/Internal_combustion_engine

    Typically forced lubrication systems have a lubricant flow higher than what is required to lubricate satisfactorily, in order to assist with cooling. Specifically, the lubricant system helps to move heat from the hot engine parts to the cooling liquid (in water-cooled engines) or fins (in air-cooled engines) which then transfer it to the ...

  8. Liberty L-12 - Wikipedia

    en.wikipedia.org/wiki/Liberty_L-12

    Oil system: forced feed, rotary gear pressure and scavenge pumps, wet sump. Cooling system: Water-cooled; Performance. Power output: 400 hp (298.3 kW) at 1,800 rpm ...

  9. Rotax 912 - Wikipedia

    en.wikipedia.org/wiki/Rotax_912

    Lubrication is dry sump, and fuelling is via dual CV carburetors or fully redundant electronic fuel injection. The electronic fuel injected Rotax 912iS is a recent development. [5] The 912's lubrication system differs from most dry-sump designs in that oil is forced into the storage tank by crankcase pressure rather than by a separate scavenge ...
