Y20DTH: electrovalva voletilor

la fel si la mine....am mai discutat asta...
lasa-mi un mesaj cu un tel de contact...sunt din Deva

Un raspuns la aceasta intrebare vine tot de la mine care am si adresat.o 😉

Swirl flap control
The adjustable swirl flaps are located in the tangential channels of the intake system and are opened and
closed according to the operating status of the engine. The swirl flaps are closed under the following
conditions:
# at low engine speeds and low injection volumes (map-controlled)
The swirl flaps generally remain open when
# the coolant temperature < 15°C OR
# the intake air temperature < 15°C
Function
The pressure converter connects the vacuum unit with the vacuum supply by means of hoses. When
activated by the DDE control unit, the changeover valve switches vacuum to the vacuum unit. The vacuum
unit actuates the control rod and the swirl flaps close. The control rod is up against the rear stop when the
swirl flaps are open.
Troubleshooting
If a fault is detected in the control of the pressure converter, the following faults may be detected:
# 4130, Activation short circuit to B+
# 4141, Activation short circuit to B-
# 4152, Activation circuit break
# 4153, Excess temperature output stage
Effects of faults
If the swirl flaps stick in open position: Deterioration in exhaust gas characteristics in lower speed ranges
otherwise no effect.
If the swirl flaps stick in closed position: Power loss of approx. 10% at higher engine speeds.

poti sa descrii mai exact cum functioneaza....la relanti si la turatie eu nu i.am facut testul ink dar suspectez turbina ,cam are joc axul si da si ulei...senzorul de boost l.am tot curatat dar nustiu ce influenta ar avea asupra voletilor care sunt actionati de electrovalva....precizez ca e cam puturoasa mai ales in trepte superioare si la de pe la 2500 in sus nu se mai tureaza asa bine...nust cum ar trebui sa fie pt ca nu mai mers cu o masina identica. astept pareri!

poti sa precizezi cum e miscarea? trebuie sa fie destul de sesizabila in sensul ca tija sa faca o cursa completa deci inchis ? la mn se misca dar insesizabil. Am mai auzit o varianta comform careia doar in sarcina se poate vedea cum se misca, cu adevarat tija aia. Cum merge masina cand ai senzorul bun(deci cel care permite si miscarea voletilor) si cum merge cu celalalt? poate senzorul care nu merge e setat pentru alti parametrii....sau sa aiba si egr.ul electronic sau vacuumatic vreun rol aici?

Deci la mine cand accelerez brusc aproape ca nu se intampla nimic....foarte putin se simte tija deci insesizabil! Sa fie oare din cauza electrovalvei ? am inlocuit.o cu cea de la turbo si tot asa se intampla....nu mai stiu ce sa cred...ms oricum!

Nu o fi ea de vina dar vacuum are, si furtunele de vacuum le.am verificat si sunt ok la intrarea in electrovalva e vacuum si la iesire e foarte slab si la accelerari bruste nu se schimba valoarea depresiunii...capsula deasemenea tine aerul nu e sparta membrana....nu mi.ai raspuns cum iti trage masina cand lucreaza capsula ? Stima
