what do you mean by that? the power of the engine, pully ratios?, kilojules of energy used? eh?
ah. i doubt anyone knows that... i can't think how you'd go about working that out...

nor me thats the problem! think im going to hve to blag that part of the assignment!
"Research you chosen system(alternator), include in your discussion applications where the system is used, include diagrams and applicable values." ehh! O and 2000 word btw! im screwed!

Bombz (you idiot!!) why leave something like this till the last moment!!! If it helps most comments I have seen is that the load places upon the engine by an alternator is generally around 5hp. You could claim that it was too difficult to accurately load an alternator (although wouldn't be accepted at uni, as you should know how to take accurate results 
.) But the loading from the belts alone takes a fair bit of power, then there is the alternator fan, bearings and finally the loading of the energy being produced. You have not particulary made this easy for yourself haha. There should be plenty of examples on the web of alternator vs power output but again, this usually talks about the RPM of the engine not the alternator (from what I have seen) and so without the known gearing ratios i wouldnt know how much faster the alternator is spinning... one could guess but uni isnt about guess work

You're at university....you should have learnt by now that you can't leave things until the last moment.
Uni is also totally different, it depends on you studying for your degree (i.e. "reading for your degree")!
If you'd popped into your library for an hour or so, you would have found quite a number of books on the subject, many of them under power/energy along with the automotive section.
Good luck with it, but try not to do it again!!!
Edit: If its a 2000 word essay you'll definitly need to quote sources, probably using Harvard referencing. So get down the library and read some books!

Hi Bombz,
Good Luck with this I scraped my through my Mech Eng degree too, graduating 2005.
I've just done a quick google search, and this seems like it may be slightly useful:
http://www.zena.net/htdocs/alternators/AutoSound.shtml
Click on the link to their automated email response, it's not exactly what your after, but gives you an idea of their alternators most efficient operating speed, and what that equates to in engine power.
Hope this helps mate, I know what last minute degree essays are like I spent 4 years doing them!! Lol
All the best,
Chris.
