Automotive Lubricants - A lubricant is generally a fluidic material with the primary function of reducing friction between surfaces in contact.
What is the most commonly used lubricant in automobile?
Engine oil is the most common type and also one of the most crucial automotive lubricants. Engine oil is responsible for the complete lubrication of the combustion chambers of the engine by reducing the friction of moving parts. [Automotive Lubricants]
What is lubrication in automobile?
Lubrication is the control of friction and wear by the introduction of a friction-reducing film between moving surfaces in contact. The lubricant used can be a fluid, solid, or plastic substance.
What is lubricating oil used in automobile?
Lubricating oil, sometimes simply called lubricant/lube, is a class of oils used to reduce the friction, heat, and wear between mechanical components that are in contact with each other. Lubricating oil is used in motorized vehicles, where it is known specifically as motor oil and transmission fluid.
What is the composition of automotive lubricants?
Typically lubricants contain 90% base oil (most often petroleum fractions, called mineral oils) and less than 10% additives. Vegetable oils or synthetic liquids such as hydrogenated polyolefins, esters, silicones, fluorocarbons and many others are sometimes used as base oils.
What are the three 3 types of mechanical lubricants?
Lubricants are classified into four types: oil, grease, penetrating lubricants, and dry lubricants. [automotive lubricants]
Which is widely used lubricant?
Magnesium stearate (most widely used lubricant), stearic acid, hydrogenated vegetable oil, mineral oil, and talc (generally requires high concentrations ~5%).
What lubricant is used in IC engines?
Mineral oil is the lubricant used in IC engines the most frequently, and it is made by refining petroleum.
What is the principle of lubrication?
Lubrication is a process which aims at reducing friction between two moving pieces. When two surfaces come in contact with one another, a fluid must be injected to separate them.
What is viscosity grade?
The viscosity grade of a motor oil provides information on the oil's resistance to flow in your vehicle's engine. A lubricant with a low viscosity grade will be more fluid, more liquid, and will flow more easily.
Why lubricants are used in vehicles?
They control friction and wear in the engine, they protect the engine from rusting, they cool the pistons, and they protect the engine oil stored in the sump from combustion gases.
What are the 4 types of lubricant?
Lubricants are classified into four types: oil, grease, penetrating lubricants, and dry lubricants. The two most common lubricants you'll encounter on a daily basis are oil and grease, but your facility will still use dry and penetrating lubricants.
