Somewhere - I must get round to throwing it out - I have a PC with a
"Turbo" button which runs the 386 inside it at an amazing 16MHz (12MHz
otherwise).

The original PC "turbo" buttons ran the machine at 8 MHz instead of 4.77
MHz!!

......but not long after that Zenith really extracted the urine from
the whole turbo marketing concept by selling the "Zenith Turbo Sport
386e" laptop computer.

Sorry Bert but Mercedes 'Kompressor' engines have mechanically
driven superchargers not turbochargers.

No. In German, Kompressor is used for a mechanically
driven charger,
turbo for the exhaust driven charger.

....and then, of course, we have the Lycoming TSIO-540; with the TS
meaning "TurboSupercharged" according to the technical manual.

Sorry, couldn't resist adding to the confusion.

order going down the road. ;-)

In the US, a belt driven compressor is called a "supercharger". In drag
racing its called a "blower", the engine is refered to as a "blown"
engine, cause that's what you end up with. ;-)

Hi Jim

Strictly speaking a turbocharger is a supercharger since they are both
forced induction systems. As you know the difference is that the turbo' is
driven by the exhaust gasses. It is now generally accepted that
superchargers are the mechanically driven variant and turbochargers are the
gas driven ones.

Probably when the 540 was built ( around the time of Noah and the Ark AIUI )
'TurboSupercharger' was actually the accepted term.

NOT (QUITE) CORRECT, see below.

Well, to be as correct as I can be:

"Kompressor" is the German word for, you guessed it, a compressor. So to
call a turbo charged engine a Kompressor charged one is, strictly
technically spoken, correct.

Yes, and what's more, to call it turbo-charged, when the compressor
is not turbine driven, is incorrect.

Historically, though, the first cars with charged engines had
mechanically driven compressors (driven by the crankshaft). They were
called Kompressor engines.

That is exactly the case of the "famous upperclass car manufacturer"
in question. I happen to have one of these as a matter of fact. Their
compressor is mechanically-, not turbine driven. Hence "compressor
charged" would be correct, while "turbo charged" is not.

The first popular sustainer engines back in the 70 or 80 of
last century had direct driven small props with
many blades, running at high RPM.
They looked more like turbines than like
conventional props. This is why they were called 'turbos'.
Somehow this name has survived up to date.
