Which book to choose depends on what info you need. I work with engines and hence think these are helpful:
Introduction to Internal Combustion Engines by Richard Stone
Internal Combustion Engine Fundamentals by John B. Heywood. McGraw-Hill Book Company, New York, New York, 1988.
Internal Combustion Engine in Theory and Practice, Volume 1 and Volume 2, by Charles Fayette Taylor.
You can ask your local public library to borrow a copy of each one -- your public library can borrow one from a university library. Check it out for a couple weeks and see if it has what you want.
There are some other engine books out there which are not as widely used:
Design Techniques for Engine Manifolds: Wave Action Methods for IC Engines by Desmond E. Winterbone and Richard J. Pearson
“Internal Combustion Engines - Applied Thermosciences”, Colin R. Ferguson, John Wiley & Sons, 1986. (ISBN 0-471-88129-5)
“Internal Combustion Engines and Air Pollution”, Edward F. Obert, Intext Educational Publishers, 1973. (ISBN 0-7002-2183-2).
These are more for fun than for professional use:
Some Unusual Engines by Setright, L.J.K., Mechanical Engineering Publications. 1975. ISBN 0-85298-208-9.
Allied Aircraft Piston Engines of World War II: History and Development of Frontline Aircraft Piston Engines Produced by Great Britain and the United States by White, Graham. Society of Automotive Engineers, 1995. ISBN: 9781560916550
