Turbo and Kompressor?

[Tumbo]

Please, explain the difference between Turbo and Kompressor to me.

[vabboud]

Turbo uses exhaust gases to turn a fan
kompressor uses engine power proper to turn a fan
both these fans boost pressure of air entering the engine to increase efficiency and power/torque output

[vabboud]

one last note, turbo is the mroe efficient since it doesn't infring on the engine's power, yet it needs "time" to have enough gases built up for a 100% functioning, which is termed as turbo lag, this si being eliminated with low pressure and sequential turbos

kompressors are power hungry, if i am not mistaken almost 200 bhp of the total power output of the merc 55K engine went into powering the supercharger itself, they stress an engine if not properly mated, although they are pretty responsive on low revs and only become really power hungry on higher revs

a bit like the opposite of a turbo

Actually a turbo steals a bit of engine power as well, the exhausts are actually braked when they have to pass through the turbo. That is why Porsche invented variable Turbo thingys. The word won't come to me

Great explenation. And remember that supercharger, blower and kompressor are all words for the same thing.

its a sequential turbo zonda where the "fan" blades change angle and position according to the most efficient aerdoynamic setting of the enterng air

That's what I meant but it has a special name which doesn't come to my mind

There is a new Golf commercial in Sweden, if I understand it correct the Golf has both Turbo and kompressor in the same engine

It should be called Variable Turbine Geometry, or Variable Vane Technology, or Turbine, or some such combination. Same idea, different name, like variable valve timing's various names.

It shouldn't have anything to do with sequential turbos..

Yeah, VW's new 1.4 TSI (Twincharger) idea is innovative, IMO. Makes the best of both forced induction methods. More power and better economy than a 2.0FSI engine, I think.

golf Gt TSI, the twincharger engine, kompressor turns till 2200 revs alone, then the turbo kick in together until 3400rpm, where it operate itself alone
it effectively eliminates turbo lag whilst providing optimal boost at all revs
it is pretty complex and requires a lot of comuter wiizardry
there is also a pressure factor, i have the operation curve, it is not limited to rpm, but at also different boost pressure there are different ocmbinations of turbo and super
it requires a hell of a plumbing system, and moreover hardly applicabvle to 6 pots and 8 pots due to ecnomic reasons

the unit in the golf is 1.4 liter giving 170bhp, and 240Nm, there are confirmations of a 2.0 liter I4 following

VW claims they were the first to try that combination but actually Lancia got there way before them.
