Suspensie/tampoane motor N47

Stie cineva ce face instalatia de vacuum la tampoanele motorului?

Cand am scos motorul, am vazut niste furtunele ce trec pe-acolo, dar n-am inteles rolul lor.

Unul era taiat complet. Eu l-am imbinat la loc printr-o cupla.

Nu mi-a trecut prin gand sa caut si o electrovalva... ce vad ca apare in schema.

 

Ce poate face vacuum-ul intr-o astfel de suspensie a motorului? Cum lucreaza? Doar sunt tampoane hidraulice.

Pai daca erau hidraulice banuiesc ca nu mai aveai vaccumul ala acolo, este clar ca ale tale sunt pe vaccum sau mixt.

Da, dar nedumerirea colegului este la ce ajuta vacuumul?

 

LE:

 

Singura explicatie care am gasit-o pe un forum:

 

Its hooked up to a valve so when the engine torques it will stiffen it up. Id say yes it is important, especially since Ive been told it could cause a vacuum leak if it is left disconnected.

 

Si un link ajutator:

Interesant...

 

Cam greu de testat efectul... dar imi voi aloca o zi sa cercetez tot traseul pentru intreruperi.

Cert e ca la mine cand am luat-o avea furtunul principal taiat si lasat liber.

 

PS: acelasi sistem e si la pre-facelift (2004-2007) - motorul M47N2.

Acel vacum lasa tampoanele jos in accelerare. Practic se lasa centrul de greutate la masini pentru o mai buna stabilitate. E38 are asa ceva si se simte daca sunt nefuctionale Edited by malasorte

Nu aveam erori, desi era taiat.

 

Daca nu simt diferenta (sau nu le vad eu) acum ca e cuplat la loc, deduc ca nu functioneaza.

Daca stiam de el cand era motorul scos, imi era mai usor sa urmaresc traseul si sa-l verific.
