Mechanical system of lubricating internal combustion engines in which a pump forces oil into the engine bearings.
-
The system which stores, cleans, cools, and recirculates oil in an engine to lubricate its moving parts and bearings. It includes the oil the oil pump , oil pan or sump or sump , oil coolers , tubing, filters tubing, filters , oil passages in the block, and dashboard and dashboard oil oil gauge . Checking the level of oil is accomplished accomplished with the oil dipstick oil dipstick . (automotivedictionary) (automotivedictionary)
-
application of some oily or greasy substance in order to diminish friction.
PURPOSE OF LUBRICATION 1.
Reduce the frictional resistance of the engine to aminimum to ensure maximum mechanical efficiency.
2.
Protect the engine against wear.
3.
Remove all impurities from the lubricated region.
4. 5.
Form a seal between piston rings and t he cylinder walls to prevent blowby. Serve as a cooling agent by picking up heat.
6.
Reduce friction between moving parts, which minimizes engine wear, and the creation of heat.
7.
Cools a variety of internal engine parts and removes some heat from the engine.
8. 9.
Removes dirt, abrasives and contaminants from inside the engine. Assists sealing of the combustion chamber by forming a film betwee n the piston rings and the cylinder wall.
10. Absorbs shock loads between bearings and the gears thus, suchioning and prote cting engine parts while minimizing engine noise pr oduction. 11. Stores an adequate supply of oil for lubricating internal engine parts. 12. Minimizes corrosion of internal engine components.
-
Employs a fully-forced feed, filtering method.
-
The oil stored in the oil plan is sucke d by an oil pump which is directly driven by the crankshaft. Then, the thus- sucked oil flows through an oil pump strainer and is filtered at an oil filter. After having passed through the passages of the cylinder block, it will be divided into two streams so as to lubricate various sections. One stream of the lubrication oil performs lubrication of various sections of the crankshaft and connecting rod and pistonrelated parts. the other stream of the lubrication, oil rises to the cylinder head section. Then, it performs lubrication of valve rocker shaft-related parts.
LUBRICATING OIL -
Processed from crude oil in a refinery with gasoline and diesel, along with many other beneficial and useful products.
