Sorry Bert but Mercedes 'Kompressor' engines have mechanically
driven superchargers not turbochargers. John Galloway At 12:42 01 June 2004, Bert Willing wrote: Errr, no.

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

....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. Jim SGS 1-26A with Cummins Turbo Diesel - but not necessarily in that order going down the road. ;-) Shawn Curry wrote 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.

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. CV |

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. -- Best regards Walter |
