OT: Anyone Know of a Good Source for Engine Information?

[tliss]

All right, gearheads....I am looking to learn a little more about engines in general (anantomy, what mkae them work, etc.). I know a little, but definitely not as much as I would like. Does anyone know a good source (on-line or book) where I can get all the information I could ever want about engines, with pictures? I figure a Chilton's manual would give me a good idea of assembly/disassembly, but it may not fulfill my need for understanding what all of the parts are for.

Any help would be appreciated.
