Infernal Combustion

[Bill Slankard]

I attended a club meeting this weekend.  The topic of the lecture was
comic books.  Afterwards I was talking to an acquaintance who does not
currently read comics.  I mentioned that Uncle $crooge was the only
comic I subscribe to, and he told me he learned how the internal
combustion engine works by reading a Disney comic in his youth (25-35
years ago).  The story involved DD getting shrunk and traveling through
an engine.  Does anybody recognize this story and where it's from?  (And
if it's been reprinted recently?)
