> OFF TOPIC - modern starters and clutches (Jay Laifman)
Jay:
I don't know all the answers to all your questions, but I do have couple
of thoughts.
First, I have always understood that alternators are more efficient than
generators, so repeatedly starting a car whose battery has been charged
by an alternator may not be such a large demand. Modern batteries really
do hold a good deal of energy, so the stop and start cycle is probably
something well within its capability. Follow a UPS truck around for a
bit for a demonstration. Newer starters are also more efficient, I
believe. You might have more of a problem with a Tiger, since it (at
least mine) uses a generator which would have more of a problem keeping
up at idling speeds (I sometimes see the red ignition light come on at
idle - something I haven't noticed with the cars I have had with
alternators.)
Secondly, I had a VW GTI in the past with the DSG transmission and it
really is a neat piece. There are really two clutches (and two
gearboxes) which are controlled electronically, making it possible to
engage and disengage the (concentric) clutches without the worry of
slipping the clutch as one would do with a manual clutch. It is my
understanding that it is the slipping that can quickly do in a clutch
but the electronics allows for that to be avoided for the most part.
Cheers,
Tod
