Introduction to Types of Lubricants - Engine Lubrication - Internal Combustion Engines | Summary and Q&A
TL;DR
Lubrication in IC engines reduces friction, wear, and tear between moving parts, cools surfaces, cleans impurities, absorbs shocks, and requires specific properties like viscosity, flash point, fire point, etc.
Key Insights
- 😂 Lubrication in IC engines reduces friction, wear, and tear between moving parts.
- 🫢 Lubricants also serve the purposes of cooling surfaces, cleaning impurities, and absorbing shocks.
- 😥 Properties of lubricants, such as viscosity and flash point, determine their effectiveness in reducing friction and providing optimal lubrication.
- ❓ Classification of lubricants includes viscosity, performance categories, catalyst compatibility, and recommendations from original equipment manufacturers.

hello everyone today in this lecture we are going to see something about the implication systems that are used in the IC engines first of all let us understand what does lubrication mean in a broad term it is nothing but when oil is introduced between surfaces which are having a relative motion in between so in any two surfaces which are having a r...

Questions & Answers
Q: What is lubrication in IC engines?
Lubrication in IC engines involves introducing oil to reduce friction, wear, and tear between surfaces with relative motion, cool surfaces, clean impurities, and absorb shocks.
Q: What are the purposes of lubricants in IC engines?
Lubricants in IC engines serve various purposes including reducing friction and wear, cooling surfaces, filling and adjoining spaces between surfaces, carrying away impurities, and absorbing shocks.
Q: What are the properties of lubricants?
Properties of lubricants include viscosity, flash point, fire point, cloud point, pour point, oiliness, corrosion resistance, emulsification tendency, physical and chemical stability, viscosity index, and oxidation stability.
Q: How are lubricants classified?
Lubricants can be classified by viscosity, performance (American Petroleum Institute categories), catalyst compatibility, original equipment manufacturer recommendations, and packaging.
