Does anybody have any info/pics on the Volvo
turbocompound D12D-500?  It uses a Holset HX55 and

a

HP72.  I have no idea of the weight or size, but

was

wondering if this could be adapted to a 20b.  I

have

no idea of the Volvo engine's flow numbers let

alone

any compressor maps.

For those of you looking into the turbo-generator,
check out this link:

Wow!!! I did not see this before I made my suggestions, Honest. Great minds
work in similar fashion :) The problem with the diesel is it already too
efficient to get much out of turbo compounding. Never the less Caterpillar
has been at the forefront of this technology for many years having built
and sold many turbo compound diesel engines.

As I said, a sea change is about to occur in automotive ICE engines.
Doug you might want to pass this on to Mazda.

?Good work Jesse,

Thanks. So this confirms that other companies are moving this way as well.
Paul I think Mazda is way ahead of us. The electric motor assisted turbo
that they are presenting as "NEW" next year at the Tokyo Motor show has been
in their test cars for almost 15 years.  I maintain to keep your eyes open
for the hybrid engine with the turbo electric generator.  Their engines are
going beyond belts towards all electric. I don't know if that includes the
water and oil pump though.  Would think that driving those two items of the
eshaft would be more compact and efficient. For hybrid electrics the
technology is here today.  Market isn't.  Toyota is changing all that
though.

Now if only I could get my hands on some real data concerning rotary engines
running on diesel fuel I would be a happy camper:)

The big drawback to electric is the less than perfect efficiency of 
the generators and motors. 85% times 85% is only 72% while a mechanical 
gear box can be up to 98% efficient. Perhaps the generators and motors
could be super cooled with liquid nitrogen :)

Wankel Germany did a lot of work in this area and they got about
.47 BSFC running on spark assisted diesel. I have a bunch of pictures
I took while in Germany.
