What is lubricant?
Like human blood, oil is the blood of the engine. For full functional operation, the engine requires high-quality oil. Various oils used in the engine to operate such as fuel, transmission oil, lubricant. Fuel is the key to engine operation addition of fuel runs the engine. The engine stays in operating mode until getting fuel.
When the engine runs some unexpected factors occur such as friction, vibration, corrosion, the heat that decrease the life of the engine. To reduce the friction, heat dissipation, reducing vibration of the engine, noise removal, increase the efficiency of the engine a substance is used called lubricant.
Lubricants prevent the engine from friction, corrosion, less vibration it cools the engine. If there is no engine oil on the operation of engine it will produce noise, higher vibration, heat great problem is that it may cause severe damage of the engine may cause a fire. Without lubricant or engine oil no vehicle is safe for smooth operation.
Lubricants give engine smooth operation, gives longer life, less fuel consumption, dissipating heat increases engine efficiency and durability.
Benefits of using lubricant
Using lubricants benefits can be described in a few lines. The engine gets a long life, great efficiency. Some of the vital benefits are discussed below
- Reduce friction: Movement of the engine causes friction of the mechanical part that makes friction. If lubricant is used the friction is reduced saving the engine life.
- Noise reduction: When lubricant or engine oil used for lubrication less friction occurs that reduces noise on engine operation.
- Reduce corrosion: Using lubricant decrease friction engine decays very slowly it gets longer life otherwise corrosion will make short life.
- Rust prevention: Lubricant prevents mechanical parts from getting rust.
- Cooling agent: At the operating time heat produced inside the system lubricant absorbs the heat saves the engine and increases the efficiency of the engine.
- Cleaning: Lubricant cleans the dirt of engine. When you buy a vehicle, the engine contains small particles needs to be cleared for full operation. There is no other method to clean it, it is cleaned by the rotation of the engine. If the engine has excellent lubrication it absorbs the particles released by the engine thus way lubricant cleans the engine.
- Seal the leakage: Engine oil seals the leakage if there is leakage inside the system.
Properties of lubricants
The properties of lubricants are
- High flashpoint
- Prevention from corrosion
- Pour point & cloud point
- Anti-freeze property
- High viscosity index
- High resistance oxidization
- Excellent thermal stability
- Neutralization number
Classification of lubricants
Based on source
There are two types of lubricants based on source viz. i) mineral-based lubricants ii) synthetic-based lubricants
i) Mineral-based lubricants:
Mineral-based lubricants produced through crude oil after refining. Generally refined crude is not suitable to use as lubricant additives added to make mineral-based lubricants usable. Normally 10% of additives added on refined crude oil to make suitable for lubrication.
ii) Synthetic based lubricants:
Synthetic based lubricants are artificially chemically compound to use as lubricants. Petroleum components are compounds with chemical treatment, there is needed to add additives to make synthetic lubricant usable.
Based on using
i) Automotive lubricants:
Automotive lubricants are chemical compounds to use only for automotive applications. There are also varieties in automotive lubricants, all the engines are not the same size or same type. So that different engine needs different types of lubricant. All the automotive lubricant is not the same they have individual grade number. Motorcycle, car, bus, truck vehicles have different grades engine oil or lubricant.
ii) Industrial lubricants:
Industrial lubricants are special treatment for industrial use only. For industrial machinery, high-quality lubricant requires, those lubricants are chemically treated for industrial use.
iii) Special lubricants:
Grease is a special lubricants mixer of oil or other lubricant combination of soap foam or semisolid typically made for special purpose usage. Special purpose lubricants are formulated for a single lubrication job.
Based on grade
i) Multigrade lubricants:
Multigrade lubricants have multi-grade viscosity at cold and hot condition both. The first number is followed for winter “W” and the second one is for the hot condition. For example, 5W-30
ii) Monograde lubricants:
Monograde lubricants are not for winter or hot condition. It is formulated for only one condition either hot or cold situation.
Based on condition
i) Solid lubricants:
Solid lubricants those are used as powder formed for lubrication to reduce friction. Example: most commonly used solid lubricants are graphite, boron nitride, molybdenum disulfide.
ii) Semi-solid lubricants:
Greases, vaseline, and waxes are semi-solid lubricants.
iii) Liquid lubricants:
Most of the application on your vehicle live is used liquid lubricants.
What are the additives?
Additives are those compounds which are used to enhance the performance of lubricants to keep the engine functioning.
- Viscosity modifier
