Overview of Course & Introduction
Course Overview
• This undergraduate level course teaches the principles of Internal Combustion Engines.
• The primary focus of the course is on the teaching of thermodynamics and Gas dynamics in internal combustion engines.
• The course provides information that will enable the engineering analysis of spark ignition and compression ignition engines and also
• It’s separate components including combustion chambers, ignition methods, fuel supply, cooling of the engines and etc…
Course Objectives
• Students successfully completing ME 315 will get:• A basic understanding of the engine behavior.
Which includes only those aspects of IC engines related to– overall operations– fundamental principles – performance characteristics.
• A basic understanding of the combustion phenomena in SI and CI engine.
• A basic understanding of the working principles of advanced technologies such as VVT, turbocharger ete…
• The ability to analyze engines; determine efficiency of the engine.

I.C.ENGINES!
DO WE REALLY NEED ‘EM?
I have always considered that the substitution of the Internal Combustion Engine for the horse marked a very gloomy milestone in the progress of mankind.
-Winston Churchill
If all the perverted ingenuity which was put into making automobiles had only gone into improving the breed of horses, we might be a lot better off today.
-Joe Gould
ENGINES!BOON OR BANE?
• Greatest invention since the wheel?
• Made transportation easy!
• Made life easy!
OR DID IT?
• Increased pollution
• Increased fossil fuel consumption
• Increased congestion on roads
BUT………..• WHETHER WE LIKE IT OR NOT….
CAN WE DO WITHOUT IT?
• DO WE HAVE VIABLE ALTERNATIVES?
THINK………• AS OF TODAY WE HAVE NO ANSWER
• MAY BE FOR AT LEAST 20 YEARS MORE!
• SO WE ARE STUCK WITH IT………!
SO WE STUDY IT………….!And so on to the course:
