dann2707 Posted April 22, 2014 Report Share Posted April 22, 2014 For one of my assignments, a part of it is to plot the aforementioned curves for the Bugatti Veyron. I have absolutely no idea how to plot these curves properly, I presume it would be for one gear? Can anyone help me pleasaaaaase Power and torque will be Versus RPM right? Thank you !

AdamR28 Posted April 22, 2014 Report Share Posted April 22, 2014 What's an SFC curve? Quote Link to comment Share on other sites More sharing options...
dann2707 Posted April 22, 2014 Author Report Share Posted April 22, 2014 Specific fuel consumption curve. Quote Link to comment Share on other sites More sharing options...
trialsalot Posted April 22, 2014 Report Share Posted April 22, 2014 Is this not like a map read out on a dyno? Could be wrong. Quote Link to comment Share on other sites More sharing options...
dann2707 Posted April 22, 2014 Author Report Share Posted April 22, 2014 Yeah, pretty much dude! Just need to know what things im looking for to make it! think i've got the SFC curve it's just the others. Quote Link to comment Share on other sites More sharing options...
AdamR28 Posted April 22, 2014 Report Share Posted April 22, 2014 I see. Yeah you just need torque and rpm. Quote Link to comment Share on other sites More sharing options...

RobinJI Posted April 22, 2014 Report Share Posted April 22, 2014 What data have you been given? Quote Link to comment Share on other sites More sharing options...
dann2707 Posted April 22, 2014 Author Report Share Posted April 22, 2014 Anything thats available from Google matey! What data have you been given? Quote Link to comment Share on other sites More sharing options...
RobinJI Posted April 22, 2014 Report Share Posted April 22, 2014 Tell them that's not a real question, and to go away until they've got one. What's the actual question, they've gotta be testing your methods of calculating something, not just your ability to find a graph on Google. I'm guessing they want you to find a torque curve online and calculate the SFC and power from it or something? You can't really calculate the torque curve without making a load of assumptions or having a plot of acceleration or something, have they told you to assume anything?

dann2707 Posted April 22, 2014 Author Report Share Posted April 22, 2014 I asked him and he didn't really give me a proper answer due to not speaking much english. Yay Huddersfield Uni! What sort of assumptions would I have to make for a torque curve? Quote Link to comment Share on other sites More sharing options...
N.Wood Posted April 22, 2014 Report Share Posted April 22, 2014 Just hand in a picture of a veyron annotated in ms paint with speed lines and 'wow, much fast'. 2 Quote Link to comment Share on other sites More sharing options...
dann2707 Posted April 22, 2014 Author Report Share Posted April 22, 2014 That'd probably get me more marks, like genuinely. Quote Link to comment Share on other sites More sharing options...
ManxTrialSpaz Posted April 24, 2014 Report Share Posted April 24, 2014 (edited) Here you are Dan, done your work for you Seriously though, have you been given any other data/information? I think it would be very hard to any meaningful work without any raw dyno data. Like for the SFC, surely you'd need to know the fuel flow rate across the rpm range? edit: SFC would be easy enough if you can find out the air-fuel ratio. Then using the compression ratio and engine capacity you know how much fuel is used across the rpm range. The tricky part is getting raw power info?

dann2707 Posted April 24, 2014 Author Report Share Posted April 24, 2014 Exactly thats why it's so hard, this assignment is rubbish! haha have only been given this. And the wikipedia page. Other than that, nothing else. But we can get info from anywhere! Quote Link to comment Share on other sites More sharing options...
N.Wood Posted April 25, 2014 Report Share Posted April 25, 2014 Could you ring a tuner and ask them what they reckon? Quote Link to comment Share on other sites More sharing options...
AdamR28 Posted April 25, 2014 Report Share Posted April 25, 2014 First result on Google images... http://www.bugatti.com/pages/72/bildspalte/acceleration01.jpg Is this primary school or a degree? Quote Link to comment Share on other sites More sharing options...
