brandstofdruk W126 280SE na pulsatie demper

Berichtdoor chiel » 20 feb 2024, 17:42

Goedemiddag allen,
Ik ben net nieuw op het forum en ben sinds november vorig jaar in het bezit van een W126 280SE uit 1983.
De auto had geruime tijd stilgestaan en is nu bijna klaar voor de APK.
Echter loopt hij niet mooi. De warm up regulator is gereviseerd en geeft de juiste waardes.

Maar als ik de brandstofdruk meet met lopende motor met vacuüm aangesloten, dan geeft hij zowel koud als warm ongeveer 1 bar teveel brandstofdruk aan. Nu vraag ik mij af of dit klopt?

Wat mag de brandstofdruk zijn als alles is aangesloten, dus met vacuüm op de pulsatiedemper?

Het betreft dus de M110 motor met K jetronic.

Heeft iemand wellicht een overzichtje van alle brandstofdrukken voor deze motor?

Hoi Michel,

De pomp moet 5-5,6 bar druk leveren (systeemdruk). De stuurdruk (geregeld door de warmloopregelaar) moet bij 0 graden Celsius tussen de 0,5 en 0,8 bar zijn (er is dan dus weinig tegendruk op de stuwschijf en deze zal makkelijk naar beneden bewegen en meer brandstof inspuiten).
Helemaal warm en uitgeregeld moet de stuurdruk dan tussen de 3,4 - 3,8 bar overdruk zijn.

Zie ook diagram.
Succes!
