Seeing the overwhelming response for the first edition and taking into account the recent developments taken place in the field of IC engines, it has been decided to bring out this second edition. Five new chapters, viz., Alternate Fuels, Electronic Injection Systems, Engine Emissions and Their Control, Engine Electronics and Supercharging have been added to make the book up-to-date. Variety of new problems have been added in various chapters and number of exercise problems have been increased. All the figures have been redrawn using computer.

The second edition would not have been possible but for the support of Ms.Vijayashree who did all the drawings and the text formatting with utmost sincerityand dedication. I am grateful to her for making this edition possible. I am thankful to all myre-search students who helped me in checking all the problems, text and figures. I hope and wish this second edition also will receive the overwhelming support from under-graduate, post-graduate and practising engineers. The author will be grateful for anyconstructive criticism for the improvement in future editions.
