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………….!
