Corsa D A13DTR - filtru particule

@mihaintz
schimba motorina cu una de mol omv sau rompetrol dar alea premium
si legat de dpf citeste asta si mai inveti cate ceva
la km care ii ai nu ar trebui sa se aprinda acel martor decat daca ai un combustibil prost care iti incarca repede DPF

Momentan absolut nimic. Am fost la dealer si nu au gasit nimic,nici o eroare nimic. Ce-i drept nu mai palpaia spirala cand am ajuns acolo. Mi-a recomandat sa vin, chiar si fara programare cand se mai aprinde beculetul. Am pus motorina de la OMV si de atunci nu am mai avut probleme. ( e drept ca am mers doar 200km)
Sambata am programat un drum de vreo 400km sa vad daca mai face...

Am mai facut 500km si nu am mai prins nici o regenerare a filtrului. Motorina Sprint diesel si mers pe autostrada; poate de aceea....
In schimb am observat ceva ciudat. Cand merg cu a 6- a indiferent de turatie (intre 2000 si 3000) consumul instant sta peste 6l/100, uneori chiar 7-8l pe la 3000rpm. Daca merg cu a 5-a chiar si la 2800-3000rpm consumul afisat de BC e sub 5%. Asta ma face sa ma intreb la ce mai foloseste a 6 a viteza?!

deocamdata de cand mi-au schimbat senzorul din filtru, nu am mai avut nici o eroare. Regenerare isi face tot la aprox 500 de km.
Azi am bagat Alto 55 diesel, de la rompetrol, am facut 150 km si am obtinut un consum de 4.1l/100 km, mers cu a 4-a si a 5-a, la aprox 2800 ture.

2100km am eu; la fel nu am mai prins nici o regenerare. Motorina am pus doar OMV. E clar ca nu-i place orice motorina. Inca mai astept scaderea consumului care mi se pare cam mare (cam 6.1 mixt).

Ce legatura are postul tau cu ce se discuta in acest topic?

Am 3500km acum si nu am mai prins nici o regenerare a filtrului. Claudiuus mie nu mi se aprinde decat spirala, niciodata masinuta cu cheie si niciodata mai mult de 5-6km nu sta aprinsa.
PS: Cum faci sa vezi cat % e infundat?

sprirala sau martorul de la bujie incandescenta are sa iti licare in momentul in care filtrul nu isi poate face normal regenerarea, zi doamne fereste sa o vezi licarind ca daca nu mai merge nici din test regenerat cam trebuie schimbat filtru si nu este asa ieftin

Exhaust Particulate Filter System Description
Diesel Particulate Filter (DPF)
The diesel exhaust after-treatment system consists of an under bonnet catalyst and an underbody catalyst, which includes the main diesel oxidation catalyst and coated diesel particulate filter. The diesel particulate filter (DPF) consists of a solid honeycomb-like body made from silicon carbide, which is full of microscopic channels, and is coated with noble metal. The diesel exhaust aftertreatment system reduces exhaust emissions such as hydrocarbons, carbon monoxide (CO) and particulate matter. The DPF collects particulate matter from the engine exhaust to minimise discharge of soot to the atmosphere. The exhaust flows through the channels and soot particles are deposited on the channel walls.

The soot particles accumulate in the channels of the DPF and are burned off at regular intervals, through a process called regeneration or cleaning. The DPF cleaning process prevents the DPF from clogging. Excess soot in filter can cause a drop in engine performance and crack the filter during regeneration.

DPF Differential Pressure Sensor
A DPF differential pressure sensor is connected across the DPF and provides feedback on soot level or exhaust back pressure to the engine control module (ECM). The pressure pipes, which are connected to the differential pressure sensor, measure the pressure differential between the entrance and exit of the diesel particulate filter. The pressure differential or back pressure indicates the amount of soot collected in the DPF. To protect the engine, the ECM enables a regeneration when critical soot level is detected in the filter.

Exhaust Gas Temperature Sensor
The exhaust gas temperature sensor is a variable resistor that measures the temperature of the output of the under bonnet catalyst and the underbody catalyst. The engine control module (ECM) supplies 5 volts to the exhaust gas temperature sensor signal circuit and supplies an ground to the low reference circuit.

DPF Cleaning
During the cleaning process, additional fuel is injected via multiple post injections to increase the exhaust gas temperature. During this period, the DPF temperature is raised to approximately 600°C (1 112°F) and the deposited soot is oxidised or burned off to carbon dioxide (CO2).

Am dat jos capacul motorului si am fact cateva poze.
In poza de ansamblu (prima poza am indicat senzorii ce mi s-au schimbat). Reamintesc faptul ca dupa primul senzor schimbat, am mers 10.000 de km fara nici un fel de problema, erorile disparand cu desavarsire. Dupa cei 10.000 de km mi-a reaparat aceeasi eroare (diferenta de presiune inainte si dupa filtru, DPF infundat 95%) si mi s-aschimbat al doilea senzor.


In a doua poza va intreb ce senzor e cel indicat? se afla mai jos, pe corpul catalizatorului, nu arata ca o sonda Lambda, si arata tot ca cel de presiune.

In a treia poza va intreb la fel, ce reprezinta acel ansamblu, corp in care intra o mufa si senzorii de presiune. ...

Astept raspunsurile voastre.
