Kurszweil may still allow you to set an engine.  Openbook used to, but they now have settings such as faster and slower, but more accurate.  It may be that one of these settings only uses one engine for speed.  One or two others use more than one and combine the results for best accuracy, or what Openbook says is best accuracy.  I haven't eexperimented much with this, but in the very little I've done, it appears to me that I may often get better results on the fastest setting.  I suspect the fastest setting only uses one engine.  I don't recall why, it was years ago, but the small amount of experimenting I did led me to believe that fastest uses Fine Reader. 
 
And just because one engine may be used in that you may be able to set one as you could and may still be able to in Kurzweil, that doesn't mean it is completely used.  For example, for a time, openbook used Fine Reader to decolumnize text, whichever engine you selected for recognition.  It may still do so; I haven't seen this discussed for a long time.  I don't know what Kurzweil did.
 
But I'm not sure what you are asking.  You can't just run an engine from Openbook or Kurzweil and not have the rest of the program running.  And what would be the point?  It is no easier to scan if you could just run the engine.  You don't have to use any other features of Openbook or Kurzweil if you don't want to.

It's my impression that both open book and kurzweil use one of the
popular recognition engines, omnipage, ABBY, etc?  With one of those
packages installed, is it possible to use just the ocr engine without
messing with the whole package?  I must put on my hacker's hat.
