Automobile engine information source?

[Canton High School <cant@DARKSTAR.RSA.LIB.IL.US>]

I have a 12th grade student seeking information about the materials used
in manufacturing automobiles.  He knows about the use of aluminum, cast
iron, ceramic, and plastic, but he needs to know more specific
information.

If you have a source to recommend, contact me at
cant@darkstar.rsa.lib.il.us.  My student and I will be most grateful for
any assistance you can offer.
