Rare pomp?

Berichtdoor Verkuilm » 26 feb 2010, 11:01

Heb een 420 uit 1986. Nu heb ik onder de dynamo een soort pomp gevonden. Kan iemand vertellen wat dat is?
Hij is verbonden met het luchtfilter.
ALvast bedankt.

dat is een luchtpomp om de emissies naar beneden te krijgen, werkt samen met de EGR (kost dus vermogen en dus benzine)

Is inderdaard een luchtpomp voor extra luchtinblazing om werkt samen met de drieweg
geregelde katalysator aan een schone emissie te komen, en kost inderdaad te veel energie

Bij mij jhoor je hem duidelijk "inkomen"

Ik geloof niet dat je je met "ons soort auto's" illusies moet maken of je wel lekker schoon rijdt.
Dat ding zou ik dus niet gebruiken. Het is eigenlijk een fake ding. Het vermengd lucht met uitlaatgas om zo de concentraties van schadelijk spul omlaag te krijgen.

Per saldo komt de zooi echt wel door de pijp, alleen met meer lucht er omheen.

Had aan het begin van mijn W126 avontuur dezelfde vraag. ;)

Die pomp werkt alleen bij lage belasting en dient om zuurstof toe te voegen in het uitlaatkanaal tbv naverbranding in de kat.
Vermoedelijk nodig om de katalysator op gang te brengen bij lage uitlaatgastemperatuur.

Er komt dus wel degelijk "schonere" uitlaatgas uit de knalpot.

Voor de APK dient de stekker getrokken te worden (zit rechtsvoor ergens bij de koplamp)anders zal de gastester een foute waarde aangeven.

Bij mij ligt de stekker gewoon los en is de EGR afgeplugd, t.z.t. vliegt de boel eruit.

Bedankt voor de reacties! Was er na wat gepuzzel ook al uit inderdaad. Als je hem er uit gooit moet ie gelijk met de EGR eruit?
Scheelt weer allerlij vacuĆ¼m slangen!!
In inderdaad je hoort hem er goed inkomen inderdaad.
Wie verzint zoiets nu weer.
