What is lubricant?
Like human blood oil is the blood of engine. For full functional operation engine requires high quality oil. Various oils used in engine to operate such as fuel, transmission oil, lubricant. Fuel is the key to engine operation addition of fuel runs the engine. Engine stays in operating mode until getting fuel.
When engine runs some unexpected factors occur such friction, vibration, corrosion, heat that decrease the life of engine. To reduce the friction, heat dissipation, reducing vibration of engine, noise removal, increase the efficiency of engine a substance is used called lubricant.
Lubricants prevent 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 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 of lubricants benefits can be described in few lines. Engine gets longer life, great efficiency. Some of vital benefits are discussed below
- Reduce friction: Movement of 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 prevent the mechanical parts from getting rust.
- Cooling agent: At the operating time heat produced inside the system lubricant absorbs the heat saves engine and increase 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 cleaned 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 release by the engine thus way lubricant cleans engine.
- Seal the leakage: Engine oil seals the leakage if there in leakage inside the system.
Properties of lubricants
The properties of lubricants are
- High flash point
- Prevention from corrosion
- Pour point & cloud point
- Anti-freeze property
- High viscosity index
- High resistance oxidization
- Excellent thermal stability
- Anti foaming
- 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 refine. Generally refined crude is not suitable to use as lubricant additives added to make mineral based lubricants usable. Normally 10% 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 is compounds with chemical treatment, there is needed to add additives to make synthetic lubricant usable.
Based on use
i) Automotive lubricants:
Automotive lubricants is chemically compounds to use only for automotive applications. There are also varieties in automotive lubricants, all the engines are not same size or same type. So that different engine needs different types of lubricant. All the automotive lubricant is not same they have individual grade number. Motorcycle, car, bus, truck vehicles have different grades engine oil or lubricant.
ii) Industrial lubricants:
Industrial lubricants are specially 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 single lubrication job.
Based on grade
i) Multi grade lubricants:
Multi grade lubricants have multi grade viscosity at cold and hot condition both. First number is followed for winter “W” and second one is for hot condition. For example, 5W-30
ii) Mono grade lubricants:
Mono grade lubricants is 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 disulphide.
ii) Semi solid lubricants:
Greases, vaseline and waxes are semi solid lubricants.
iii) Liquid lubricants:
Most of the application on your vehicle life is used liquid lubricants.
What are additives?
Additives are those compounds which is used to enhance the performance of lubricants to keep the engine functional.
- Viscosity modifier
- Corrosion inhibitor
- Rust inhibitor
- Ant wear agent
- Anti foam agent
- Oiliness agent
- Pour point depressant
- Oxidation inhibitor
How lubricant formulate with additive?
