Zdravim.

Mam M47 320D 120kw 2006.

Chcem sa opytat, ako je riesene snimanie tlaku vo vyfuku?
Popripade z coho a ako vypocitava zaplnenie DPF?

Dakujem za informaciu

snimacom tlaku napojenym medzi kat a dpf

Vypocet regeneracii je algoritmom…RJ ho pocita podla prejdenych km,dlzke tras,jazdnemu stylu atd. Snimac tlaku je kontrolny ktory pri prekroceni tlaku da pokyn rj zapisat chybu….


Regeneration
There are two kinds of regeneration:

1. Continuous regeneration:
   This form of regeneration takes place during normal driving. At exhaust-gas temperatures of between 280-350°C, continuous regeneration takes place in the form of a slow oxidation process. The soot particles cannot be incinerated until the exhaust gases reach the required temperature.
2. Periodic regeneration:
   Periodic regeneration is performed automatically by the DDE after no later than 1000 km (600 miles). On vehicles with many short-distance drives, periodic regeneration already starts taking place after just 400 - 800 km (250 - 500 miles).
   For regeneration, the intake air is reduced by the throttle valve. One or two post-injections are performed. This increases the exhaust-gas temperature to about 600 °C. The soot is incinerated with the residual oxygen.
   The periodic regeneration is performed at all speeds. The most efficient method is regeneration at a constant speed in excess of 60 km/h (38 mph) over a period of 20-30 minutes.
   The DDE calculates the time for periodic regeneration from the following values:
   
   • average distance travelled
   • average driving speed
   • temperature in the diesel particle filter
   • values from the exhaust gas pressure sensor
   The last successful regeneration can be read out by the diagnosis system

The following conditions must be fulfilled for a regeneration:[/font]

• The coolant temperature must be in excess of 75 °C
• the exhaust-gas temperature before the diesel particle filter must be greater than 240 °C
• there must be enough fuel (fuel reserve indicator light is not lit up). Whenever the reserve lamp lights up, the regeneration process is suspended.
• no fault codes from the air mass system, exhaust emission system and sensors must be saved in the DDE
• The fault codes 480A / 245700 (from F01) and 481A / 245800 (from F01) must display the status "currently not present"
• Constant driving speed above about 60 km/h (approx. 38 mph). The optimum speed is about 100 km/h (approx. 60 mph).

Super Dakujem..

Pouzivam Carly kde pozoroujem hodnotu "soot mass"
Tato po regeneracii niekedy stupa pomaly behom 600-800km z 0 na cca 25 potom sa spusta regeneracia, a niekedy stupa rapidne rychlo.. behom 50km z 0 na 25 az 28 a spusta sa regeneracia.
Jazdim vylucne len dialnice nad cca 150km.

Preco mi regeneraciu spusti kazdych 50-70km niekolkokrat po sebe? aj 7x za sebou?
a inokedy po cca 500-600km?

podotykam DPF mam nove(original z MD Bawaria - cena astronomicka + vsetko okolo DPF nove tiez z MD Bawaria) najazdene na nom cca 60000km, doteraz to islo normalne no poslednych cca 3000km to robi taketo zaujimavosti.
Regeneraciu som nikdy neprerusil, vzdy zbehla kompletna kedze jazdim so zapnutym carly. a ako som spomenul jazdim len dialnice nad 150km.

Dakujem

Software mas novy v rj?

Co viem.tak tam dávali posledné čo bolo pred cca pred rokom

Sw je tam posledná verzia.
Napalila sa tam znova - pre istotu.

Stav pretrváva.

Snimac je ôk, vo vypnutom stave ukazuje 0.
Kontrola tlaku v dpf hodnoty sú v stave ako takmer nové dpf - bohužiaľ čísla si resne nepamätám (meralo sa to pri troch roznych otáčkach - sa mi zda volnobeh okolo 17, 4000ot cca 35 ).

Mal som dole aj sanie- je takmer ako nove EGR a klapka s jemným povlakom, žiadne usadeniny karbónu. (cistene komolet pred 150000km),


Moja ďalšia teoretická otázka.
Nemôže to spôsobovať vadný vstrek/vstreky? Zle rozprasi palivo, nedobre to prehori = väčšia dymivost? Je takáto úvaha reálna?

Dakujem
