Default Electrified turbocharger

This looks like a better solution than the supercharger/turbocharger
combo: Continental and Valeo are both working on "electrified"
turbochargers:

http://www.autonews.com/article/2015...ctrified-turbo

These use electric motors to spool up the turbo at idle and low
speeds, so it's putting out boost pressure right from the start. The
objective is the same, to eliminate turbo lag.

Those are not really the same thing. The first one is an axial fan
that provides 1 psi of boost. The second and third are just electric
centrifugal superchargers.

As for electric superchargers, Garrett (now Honeywell) has one that's
either in production or about to go into production. There have been
several of them over the years, but none of them come close to the
Honeywell unit in terms of practicality. The electric fan and
supercharger listed in your links are not in the same league.

What these "electrified" turbos are about is bottom-end boost with
turbo fuel efficiency. The electric drive is just for low rpm.
Otherwise, it's a regular exhaust-driven turbocharger. It's not an
easy problem to solve. But two of the world's top Tier 1 suppliers are
close to market with their versions, so we'll see something pretty
soon.

It'll be interesting to see how it plays out, particularly with keeping
an electric motor happy when it's being run up close to the exhaust
system.

Next will be electro-turbo-compound engines, where, at high speed, the
turbine motors are used as generators. Given enough power handling
capability in the turbo motor you could use it instead of a waste gate to
regulate boost; this would work especially well in a hybrid.

Hybrid electro-turbo-compound variable timing multi-BS whatnot.

Speaking of turbines, you may have noticed that GE has finally
developed a ceramic that will work as hot-side components (blades,
blisks, etc.) in turbine engines. I wrote my first story about GE's
work on this in 1979. Finally, they seem to have figured it out.

In '79, their more modest goal was to develop a ceramic that would
work in automotive turbochargers. They seem to have leapt over that
one.

Turbo lag - tell me about it. I had a 2L Turbo. Did nice on the
freeway and here and there. Coming to a stop sign and then merge
into the far side traffic land when traffic is going both ways is
exciting. The little 2Liter would put put across the first lane and
make the curve to the left. Sometime before a crash, the turbo would
cut in and move you out of there. Bad design if merging on freeway
unless the line is long and open - then speed is possible if lane is
clear.

Martin - it was a 2.2L Turbo
