caseys Posted October 12, 2009 Share Posted October 12, 2009 Even the BBC are picking up on it, albeit from a green angle. http://news.bbc.co.uk/2/hi/business/8266975.stm Estimating that 72% of cars sold by 2020 will be turbo charged rather than NA. See, we're just being good to the environment. Some of us are literally a tree-hugging greenies. Quote Link to comment Share on other sites More sharing options...

Tricky-Ricky Posted October 12, 2009 Share Posted October 12, 2009 So if i run a big turbo, does that make me greener;) Quote Link to comment Share on other sites More sharing options...

jonathanc Posted October 12, 2009 Share Posted October 12, 2009 about time Hopefully insurance premiums will also be lower for turbo motors becuase of this. Quote Link to comment Share on other sites More sharing options...
Scott Posted October 12, 2009 Share Posted October 12, 2009 I haven't read it, however... Surely the ratio of CO2 is directly related to the amount of fuel being used? What does a turbo have to do with that ratio? Quote Link to comment Share on other sites More sharing options...

What does a turbo have to do with that ratio? Because when the turbo isn't being used (IE low RPMs, town driving), it doesn't require as much fuel.

Scott Posted October 12, 2009 Share Posted October 12, 2009 Because when the turbo isn't being used (IE low RPMs, town driving), it doesn't require as much fuel. Exactly, so when the turbo ISN'T being used its more fuel efficient and better for the environment. So why have a tubby? Is it for sports cars only or something? Are they saying that for a 200bhp car its better to have a 120-150hp engine and tubbying it so that 200 is on tap but for about town driving you won't be using it? So an N/A engine capable of 200hp uses more fuel than a turbo engine capable of 200hp when at lower revs? Surely thats what variable valve systems do?

Variable valve timing systems do this, just to a lesser extent. Modern engines combine variable valve timing with turbo charging to maximise efficiency. Fitting turbos to small lumps isn't only for sports cars, it's handy have a bit of poke smetimes in any car Quote Link to comment Share on other sites More sharing options...
edge Posted October 12, 2009 Share Posted October 12, 2009 Hopefully the insurance will be isanely high for young drivers as i think it will drive people mad with the sound of dump valves everywhere. But the plus side should mean the cost of turbo's come down and reliabilty increased through development Quote Link to comment Share on other sites More sharing options...

Doesn't sound like it will make a huge difference but i guess every little counts. Quote Link to comment Share on other sites More sharing options...
jonathanc Posted October 12, 2009 Share Posted October 12, 2009 Well, I hope that multi turbocharger setup will also be researched. Make quad turbo affordable for all! Also, if I remembered correctly, there's a VW engine with both a supercharger and a turbocharger. So, I guess that must be ultra efficient then? 2 supers and 2 turbos...mmmmmmmmm..... I think I creamed ma pants Quote Link to comment Share on other sites More sharing options...

Someone (Dimitri) was planning on a 2JZ twin-charger setup but I'm not sure how far along his came. Twin-charging is good for smaller engines, but the jury is out on whether larger engines respond quite as well because of the power sapped getting the supercharger spinning. I'd love to see it done though. Perhaps someone in the UK will do it... Quote Link to comment Share on other sites More sharing options...
Thorin Posted October 13, 2009 Share Posted October 13, 2009 Also, if I remembered correctly, there's a VW engine with both a supercharger and a turbocharger. Golf TSI, a 1.4 twincharged. Quote Link to comment Share on other sites More sharing options...
caseys Posted October 13, 2009 Author Share Posted October 13, 2009 Golf TSI, a 1.4 twincharged. Nothing beated the old Lancia with a tri-flux engine (or what's what they called it). I am hoping that yes this'll drive turbo development even more, neccessity being the mother of invention/innovation. Admittedly motorsport and big industry has/is driving turbo innovation most at the moment. Would be good to see more triple-scroll turbos though... and understand how the heck they work.

martini Posted October 13, 2009 Share Posted October 13, 2009 This'll mean cars go down to 0.5l engines with a teeny turbo I'm looking forward to turbos in F1 again. Quote Link to comment Share on other sites More sharing options...
