Salut,

dupa cateva luni de cautari(cam din luna mai), am gasit si l-am cumparat. E28, 520 K-jetronic, anul de fabricatie in talon zice 1979. Nu e rea, cu tabla sta binisor, sigur a mai fost reparata candva. Chiar si asa este de lucru la ea, oalele ar fi cel mai urgent de facut, ambele au cateo gaurica mai spre parbriz cumva, pragul din stanga de la sofer si ici-colo cateo sudura mica. In rest exteriorul e chiar in regula. Desigur, stiu ca
o sa apara o gramada de alte surprize pe cand ne apucam de tinichigerie dar le pastram pentru atunci. O revizie mare de tot si pe final o vopsea proaspata.
La partea electrica sta cam prost, nu merg stopuri, becuri in bord, acele is cam intepenite, mai uita sa urce sau sa coboare.Cu motorul ma cert de cateva zile, de asta m-am hotarat si m-am grabit sa fac un topic, poate ma puteti sfatuii cu una alta. Am reusit sa-l pornesc, am si fost la o tura mica cu el, merge, nu bate, trage, e ok. Tot ce i-am facut pana acum, a fost sa-i inlocuiesc furtunele coapte de aer. Problema e ca nu porneste la cald, dimineata cand ma duc la el porneste fara probleme, sta turat pe la 2100 si incet-incet in interval de 3-5 minute coboara la 1100~. Ce ma deruteaza la el e ca a avut gaz si acuma jumate de instalatie e pe masina, jumate e prin portbagaj, Nu vreau gaz laugh.gif parca nu m-as baga eu sa-l dau jos si are cateva "T"-uri pe furtune care ma gandesc ca au avut legatura cu gazul. Asa ca, intr-o alta ordine ar urma

un schimb de ulei si filtre
bujii
fise
Daca aveti alte idei, chiar va rog, astept..

Cam asta ar fi pasul intai, as vrea sa-l aud ca merge frumos, ca porneste...

Am inceput si o lista cu piese de care as avea nevoie, poate le aveti unii din voi depozitate pe undeva..

Bara fata+elementul din mijloc de chrom
Suportul de plastic din spatele suportului de numar
faruri ceata
capota+macarale capota
un bord
volan original (are unul super tuning momentan)
cu nuca aceasi poveste
o antena


alte probeme:

timoneria


Mai sunt multe, intretimp astept parerile voastre binevenite.

Ce motorizare e? Cilindree, numar cilindri.
In 79 nu era inca E28. Nu e cuma E12?
K-jet stiu ca a fost pe E21 si o perioada scurta pe E12 520/4. Restul a avut L-jet sau carburatie.

Stiu treaba asta, scrie 1979, la fel m-am gandit si eu ca ceva nu pusca. In acte e totul ok, sasiu, motor...nu apare vreo modificare

https://www.google.ro/search?q=e20+k-jetron...=e28+k-jetronic

Motorul e M20-ul in 6 cilindri, 2000 cmc
Am sa revin cu poze, dar e28 este..

Am uitat de combi asta. K-jet e mai mult injecție mecanica. Trebuie studiat cum stabileste amestec la cald si la rece.

Nu e chiar asa simplu, nu prea are sensori, foarte mult e mechanic si cu ceva componente in plus pentru mers la rece.
As incepe cu verificare daca nu cumva la motor cald mai injecteaza benzina prin injector de pornire la rece, daca mai functioneaza ok 'warm up regulator'. Apoi as face o verificare amestec la cald si as verifica avans la aprindere (mechanic si vacuum). Daca toate astea sunt ok pornire la cald ar trebui sa fie ok.

Ai de invatat cum functioneaza..

si uite ce scrie aici:
http://www.k-jet.org/articles/information/...ebugging-guide/

Difficulty Starting Engine Only When Warm

1) Cold start injector stuck open or leaking
2) Control pressure too high or too low
3) Regular fuel injectors leaking
4) Wrong rest pressure



Bujiile cum arat? Miroase a benzina la toba cand merge?

Fix asta ma gandeam si eu, l-jet se bazeaza mai mult pe niste vacuum-uri care in general cedeaza, problema e ca majoritatea mecanicilor cauta problema in furtune - e normal, ca acolo te uiti prima oara - dar nu se mai uita si prin membrane sau nu stiu cum sa le verifice. Din ce tin minte de la L-jet-ul meu, sunt 2 piese care trebuiesc schimbate din cauza ca imbatraneste cauciucul membranei. Sau poate unul era mai sensibil.

(asta nu exclude si niste furtune crapate)

Diferența ţntre k si l jet este foarte mare.

Am doar pozele astea de cand am adus-o acasa, am sa-i mai fac cateva dupa ce terminam cu ploile astea.

Am verificat bujii. Unele sunt negre altele caramizii... iar ca miros de benzina, nu stiu ce sa zic..poate, da foarte putin.
(multumesc de ajutor!)

Mai revin cu update-uri zilele viitoare, deocamdata astept de la anaf adeverinta sa ii pregatesc actele pt inmatriculare si intretimp daca mai gasim niste loc intre munci,
facem o vizita si la masina.

salut!

sigur ca am scapat de multe tiganii de pe ea...

E o rabla. Ideea era ca se vede bine ceva componente specific k-jet.

la min 2:00 se vede ca o sa mearga fix in 4 sau 5 (la inceput da scanteie doar pe 4 bujii, apoi pe 5) tongue.gif

foarte misto clipu, i-am dat si subscribe gagiului, nush de ce imi place la nebunie sa ma uit la d-astea. orice vechitura merita repornita, chiar si daca urmatoru' stop o sa fie la fier vechi.

vazusem ca au pornit-o p-asta, nu pot sa cred ca si merg cu ea! https://www.youtube.com/watch?v=0svB5OT5pGE

Fix la asta ma gandeam si eu ca nu da scanteie, dar asta sunt problemele cel mai usor de rezolvat: bujie fise capac delcou platina celb (15).gif
