I was reading this interesting article in the Telegraph:
www.telegraph.co.uk/motoring/main.jhtml?xml=/motor...l
Looks promising. Wander if this is achievable in real world motoring?

I sometimes wonder whether complexity is just for the sake of it in some hybrids because its possible to do it.
I mean you could fit a car with a moped (fisi) engine on a wooden frame and lower it using a toilet chain suspended from the roof if you wanted to get more torque before the turbo comes in....

It's interesting, I remember reading a piece from a couple of years back about a similar Saab prototype motor that had variable compression ratio, achieved by tilting the cylinder head via an electric motor.
|
If the pressure sensors described in the article are anything like the Kistler ones fitted inside a spark plug, they're very expensive. I priced some up about 10 years ago, and they were £12K apiece!
They are expensive because they need to be small, fast acting, withstand extremes of temperature and pressure, and for production use will need to demonstrate a good fatigue life. Their signal also needs to be carefully shielded, and then expensively conditioned using a charge amplifier before it is useful.
I never cease to be amazed about the Luddism that some people on this site always profess. Taking to it's logical conclusion, some people on here must still be a bit suspicious and wary of the concept of the wheel itself!

Yup. I reckon the guy who invented the wheel must have been a moron.
Thank heavens somebody else had the brains to invent the other three.
I'll get me coat...
|
And three cheers for the guy who invented venetian blinds.
....Were it not for him, it would have been curtains for us all.
Sorry, back to thread.......

53 mpg... I could get 60mpg out of a Maestro Clubman D 18 years ago...
Bet they fitted it with alloy wheels too....
