Later systems collect oil in a sump, from where it can be collected and pumped around the engine again, usually after rudimentary filtering. This system has long been the norm for larger internal combustion engines. A pumped oil system can use higher oil pressures and so makes the use of hydrostatic bearings easier. These gave a greater load ...
Grease fitting on a bearing A grease nipple on the driver's door of a 1956 VW Beetle. A grease fitting, grease nipple, Zerk fitting, grease zerk, Alemite fitting, or divit is a metal fitting used in mechanical systems to feed lubricants, usually lubricating grease, into a bearing under moderate to high pressure using a grease gun.
An automatic lubrication system consists of a reservoir with a pump, feed lines, metering valves, and injectors. 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]
By 1970, the NCH product line included about 250 items, sold under the names "National Chemsearch," "Certified," "Mantek," and "Dyna Systems" (fasteners). Turf maintenance supplies, paints and sealers, and sewage treatment chemicals were offered along with the growing list of cleaning chemicals.
In this case, the lubricating system must be especially robust to prevent engine damage. [2] Most engines in cars on the road today don't run much past 5,000–6,000 rpm, but that isn't always the case in performance engines, where engine speeds could reach up to 8000-9000 rpm.
While there is an entire industry surrounding regular oil changes and maintenance, an oil change is a relatively simple car maintenance operation that many car owners can do themselves. It involves draining the oil from the engine into a drip pan, replacing the filter, and adding fresh oil.
More complex dry-sump systems may scavenge oil from other areas where oil may pool, such as in the valvetrain. Power can be further increased if the dry-sump system is designed to create a vacuum inside the crankcase, which reduces air drag (or 'windage') on moving parts as well. Improved pump efficiency to maintain oil supply to the engine.
