Krajši interval regeneracije

[SpEkTr]

A ima kdo kako uporabno informacijo, zakaj bi bil interval regeneracije kar naenkrat za 150km kraj?i kot v  vseh teh letih?

Se pravi iz cca 400 na 250km? Zadnji? ko sem to opazil sem mislil ok, mogo?e je kako vmesno preventivno ?i??enje. Ampak danes je ?e spet na 255km, se dela.

 

Moram pogledati s Forscanom, ampak zadnji? sem videl, da nivo saj ?e zdale? ni doseglo 60% kot ponavadi, ampak je ra?unalnik zagnal regeneracijo mnogo prej. 

 

Par dni nazaj sem bil na servisu, ?obe so v redu, drugih te?av (vsaj vidnih) ni. 

 

Zdej ?e bi avto ful dimil, bi zastopil da se prej regenerira, ampak bi zastopil tudi da se regenerira pri recimo 60%??

[Boss]

Jaz sem imel regeneracije od novega okoli 250km potem je pa padlo na 80km tako, da ti si ?e prekleto na varni strani.

[SpEkTr]

Dobro sam tvoj je 2.0 motor, lahko da so meli takrat manj?i filter. Tle je bilo vedno okoli 400. Morm malo raziskat tole. Kar lahko naredim je, da resetiram te nau?ene vrednosti za DPF filter, nimam pa pojma ?e bo to karkoli pomagalo.

[Aless]

Hmh, verjetno vpliva obraba dpf filtra, tudi jst sem zadnji 2 regeneraciji opazil da sta se dogajale pri cca.40-45% napolnjenosti dpf filtra prej pa tam med 50-55%. S tem je padla razdalja med regeneracijami iz 180-200km na cca120-150km.

Bom videl ?e bo ?e naprej delalo regeneracije na 40% je verjetno dpf ?e tolk obrabljen

[LabiGT]

Men se je pa zdel mojih 450km premal :-)

[SpEkTr]

Obrabo bi razumel ,?e bi regeneracija padla na 400km pa pol na 360,ne pa takoj na 250?

 

Loh probam staticno regeneracijo,sam sm lih olje menjal

[Tadej7ad]

Injektorji.

 

Nov DPF je pomaga. S ?asom se injektorji zapacajo in ne razpr?ijo ve? dovolj. Posledi?no ve? saj. Tudi regeneracija ne poteka optimalno (izguba mo?i na za?etku)

[SpEkTr]

Hm.....logike, sicer iz 2.0 ma?ine ampak ok:

 

Regeneration Control ? The regeneration control determines the soot amount accumulated in the DPF and subsequently starts the regeneration process. The regeneration control is integrated in the PCM. Soot Amount Calculation

? The PCM receives information about the soot amount accumulated in the filter from the DPF differential pressure sensor. In order to establish the soot emission of the engine, the PCM evaluates the customers driving method by monitoring the engine load, engine speed and vehicle speed. In addition, the PCM calculates the soot amount burnt off in the DPF using the signals from the HO2S and the exhaust gas temperature sensors.

 

? Depending on the signal from the DPF differential pressure sensor, the calculated soot emission, the burnt-off soot amount and the distance travelled, the PCM decides whether and when a regeneration should be carried out. In this way, the filter does neither become blocked nor damaged by a violent regeneration following an over-accumulation of soot. As a result, it is possible to maintain the long-term integrity of the DPF while achieving minimum fuel consumption, minimum oil dilution and optimum engine performance. ?

 

If the soot accumulation rate in the DPF is 80 % or more, the DPF indicator light illuminates. In this case an automatic regeneration of the DPF must be performed by driving the vehicle at an engine speed of 2000 min-1 or more and a vehicle speed of 40 km/h or more for approx. 10?15 min. As soon as the automatic regeneration process starts, the DPF indicator light turns off.

 

NOTE: Although the DPF indicator light turns off when the automatic regeneration is started, the regeneration process is continued until the soot accumulation rate decreases to 60 % or less.

 

NOTE: If the customer complains that the DPF indicator light illuminates frequently, he must be informed to change the driving method (they should drive the vehicle at middle or high engine speeds for a longer distance), so that regeneration of the DPF is enabled. ? If the soot accumulation rate in the DPF reaches 100 % or more, the DPF indicator light flashes and DTC P2458 is stored in the PCM. In addition, the PCM reduces the fuel injection amount to lower the exhaust gas temperature, preventing the filter from overheating.

 

Due to the reduced injection amount the soot emission of the engine and hence the soot amount accumulated in the filter is also reduced. In this case a manual regeneration of the DPF must be performed. Service Training Mazda6 Facelift 01-73 Diesel Engines Engine

 

NOTE: Do NOT perform automatic regeneration when the soot accumulation rate in the DPF is 100 % or more, since this may cause damage to the filter or the engine.

? If the soot accumulation rate in the DPF reaches 140 % or more, the MIL also illuminates and DTC P242F is stored in the PCM. In addition, the PCM further reduces the fuel injection amount and hence the soot emission of the engine, resulting in a lower soot amount accumulated in the filter. Here, a manual regeneration of the DPF must also be performed.

 

? If the soot accumulation rate in the DPF reaches 200 %, the filter cannot be regenerated anymore and must therefore be replaced.

 

Due to the effect of the catalytic coating the diesel particles are burnt off above a temperature of 500 ?C. Since the exhaust gas temperature during normal driving is between 150?400 ?C (depending on the engine operating conditions), it must be increased artificially by external intervention from the engine management system to start the regeneration process.

? If regeneration of the DPF is required, the PCM checks whether the engine operating conditions are suitable to start the regeneration process. If the requirements for regeneration are met, the PCM performs the following measures to artificially increase the exhaust gas temperature: ? Closing the EGR valve to increase the combustion temperature by increasing the oxygen proportion of the cylinder charge ? Closing the ISV partially to increase the intake air temperature by throttling ? Performing an early post-injection to increase the combustion temperature by burning an additional fuel amount ? Performing two late post-injections to increase the exhaust gas temperature by burning fuel in the oxidation catalytic converter ? By these measures the minimum exhaust gas temperature of 150 ?C (at low engine load and engine speed) is increased to 500 ?C and regeneration starts. Then the PCM monitors the regeneration process using the signals from the DPF differential pressure sensor and from the exhaust gas temperature sensors. Control over the regeneration process is critically important since the DPF is damaged when its temperature exceeds 1000 ?C.

 

? The regeneration process takes up to 15 min. When regeneration has started it will be completed regardless of the engine operating conditions. It is only stopped when the engine is shut off. In this case, the regeneration process is started again once the required operating conditions are met. Service Training Mazda6 Facelift 01-75 Diesel Engines Engine Regeneration Intervals

 

 

? Depending on the operating conditions of the vehicle the DPF is regenerated every 100?300 km. Due to the ash residues that have formed from the engine oil and diesel fuel the usable filter volume is reduced. Since the ash amount accumulated in the DPF increases with every regeneration process, the regeneration intervals become shorter with rising mileage. NOTE: High fuel consumption, low fuel quality (high sulphur content) and high engine oil consumption accelerate the accumulation of ash in the DPF, shortening the regeneration intervals more quickly.

Zanimivo. ZDele mi ni dalo miru in sem se ?el malo vozit, spremljajo? parametre. No in ker je bil PID PM_GEN enak 0 g/l, PM_ACC pa ?e vedno 3.0 g/l, je seveda regeneracija bila ?e kar aktivna, ?eprav po % in gramih ni bilo notri ve? saj. Ne vem zakaj sta dva pid-a za te saje sicer, ampak ok.

 

To sem ?e zadnji? opazil, ma izgleda kot da ne bi bilo nekaj v syncu. Regeneracijo za?ne na polovici kapacitete, in jo izvaja tudi potem ?e ko so saje skurjene. In to konkretno vsaj 10 minut ?e. Skratka, ko je res kon?a, sem s Forscanom pogledal oba PIDa en jebil 0 en pa NE. No potem sem pognal stati?no regeneracijo za 5 minutk, da je pokuril ?e tisto kar naj bi kao ostalo, zresetiral sem ?e nau?ene DPF vrednosti in to je pa tudi vse kar lahko naredim.

 

Zdej bomo pa videli, ?ez par dni kako in kaj. Res huda matematika ni kej

[Scr3am]

Ker forscan imas to, da lahko vse to delas ?

[SpEkTr]

Zadnjega na forscan.org, za windowse

No zgleda je PID PM_ACC_DSD tisti, ki ?teje. No saj tako en iz poljskega foruma pravi. Pri meni je ta vrednost 0.2 g/l se pravi bi moralo biti ?isto ok.

 

Very interesting thread. I also made some observation of my DPF. My car is Mazda CX-5 2.2 SkyActive Diesel, it has about 184000 km now. My observations: 

PM_GEN value rise quite linear. 

PM_ACC depends on load - can rise very fast on high load - it SYNCHRONIZE with PM_ACC_DSD value after some time (look on chart). 

PM_ACC_DSD - IMO it can show real DPF wear (dunno if its correct word for this case). In my case, after normal DPF regen process, PM_ACC_DSD can't reach value lower than ~3. After some time PM_ACC sync to PM_ACC_DSD. It cause to start regen process every 50-70km in my case. First thing to help my regen process was blinding EGR valve. Regen intervals rise, it took 100-120km between regens. Second thing i did - some chemical cleaning of my DPF in workshop - it help, PM_ACC_DSD value can be lower to 0.8-1.4 after normal DPF regen process. Now i have regens between 150-220km.

Kolk pa ima? prevo?enih kilometrov?

Pa kolk ma? DPF_REG_CNT?

[SpEkTr]

Ma prevo?enih je 135, dokaj malo da bi bil DPF ?e hin. Tale PID pa ne vem, mislmi da se resetira, ko resetira? nau?ene vrednosti za DPF. Vsaj mislmi da, moram ?e enkrat pogledati. Zaenkrat  bom malce spremljal tele vrednosti, sej je kar zanimivo. 

 

Potem bom probal s kakim aditivom, ?eprav je to bolj bla?ev ?egenj. Ker pri prej?nji sem imel krepko ?ez 200, pa ni bilo te?av z DPF, se je pa tudi interval po?asi po?asi kraj?al. ne pa kar takole iz danes na jutri za 50%. 

 

Ob?utek imam, da je ra?unalnik nekaj zabluzil,..lahko pa da se motim

[uklopko]

Si bom tukaj malo sposodil temo....po cca 3200 prevo?enih.....se dpf regeneracija ?e ni pri?gala. Vsak dan nardim 100km polovico te poti je AC? Je to normalno?

[SpEkTr]

Kako ve? da se ni. To dela v ozadju, in ?e res nisi pozoren na dolo?ene parametre ne ve? da kuri saje

Sem skor zihr da se je v 3200km delala regeneracija, v glede na to da ga nafila do 50% po cca.200km, se pravi je 100% nafilan po 400km. S tem da pri 100% napolnjenosti gre avto v zasilni program in dpf lu?ka.

Hmh, glede na kilometre ?e dpf ne bi smel biti zani?, no vpra?anje je tudi koliko regeneracij je v teh kilometrih naredil.

Jst mam pri 262kkm dpf_reg_cnt na 451.

 

Samo resetiranje vrednosti dpf-a se bi naj delalo ko menja? dpf, vsak tak info sem dobil od mehanika na mazdi.

 

Ma ta ekologija je avte totalno sfu...

[SpEkTr]

Ja, jaz tudi mislim da ne bi smel bit fu?. Bom pogledal ?e tale ?tevec, ?e je sploh ?e validna vrednost. 

[uklopko]

Aha...sm mislil da takrat ko kuri saje dpf utripa.....sem pa parkrat res porajtal da se je trenutna poraba dvignila....potem pa je to to ...hvala za info.

[SpEkTr]

@Labi, daj prosim preveri pri dizelci, te zgornje tri PIDe kake ima? kaj vrednosti? Lahko tudi kdo drug pove. 

 

 

[jacques33]

Jaz sicer nimam aplikacije na telefonu, imam pa izpis testerja iz servisa, ki so mi ga naredili v BTC-ju v za?etku septembra.

 

PM_ACC: 0

PM_ACC_DSD: 0,06

PM_GEN: 0,45

 

Priznam, da niti ne vem, kaj te vrednosti pomenijo, Jure mi je le rekel, da je avto tip top. Gre se pa za Mazdo z 2,2 dizlom v nosu in 163k km prevo?enih. Regeneracije mi redno dela med 400 in 450 km, zadnja se je delala po 420 km. Se je pa regeneracija delala na skoraj 500 km, ko sem tankal ta dra?jo OMV-jevo nafto.

[SpEkTr]

Ker letnik pa je? Ja, tile parametri ?e je tako kot si razlagam (kar si mi v bistvu potrdil) so res tipi top.  Kot ka?e so bili ti podatki zajeti kmalu po uspe?ni regeneraciji filtra. Pomeni, da nima? kaj dosti 'oblog' oz. pepela v filtru in je prakti?no celoten volumen filtra namenjen da lovi saje.

 

Pri meni je pa o?itno problem v tem, da se je ?e uporabni volumen filtra malce zmanj?al zaradi pepela. Zakaj , nimam pojma. Kilometrov imam 134000, se pravi kar nekaj manj od tvoje mazde.

 

Pred tem je tudi meni delal regeneracije na dobrih 400km. Edino, ?e se res toliko pozna da se ne vozim veliko, cca 12km v eno smer in nazaj dnevno. ?eprav, ko je delal regeneracije sem vedno sku?al narediti tako ,da je dokon?al.

[jacques33]

Letnik je 2010/7, facelift 2. generacije. Ja regeneracija se je izvedla ravno na poti na servis. Imam pa jaz ve?ino vo?nje na avtocesti na relaciji Kranj-Ljubljana in nazaj.

[SpEkTr]

Aha, pri prej?nji mazdi sem imel tudi jaz tako relacijo in nikol ni bilo te?av s filtrom. Daj ob priliki, pripopaj ?e parametre ko bo? nekje na sredi intervala. Aja, nima? ELM adapterja?

[jacques33]

?al nimam.
