Diesel particulate filter DDE5.0/6.0/6.2meego kirjutas:OT: Sain siin ühe E61530d puhul uuritud ka seda kübemefiltri asja veits lähemalt ja nii palju kui mina aru sain tema tööpõhimõttest, siis see on veits vale jutt et kestab kuni 200 000km aga kindlalt ei väida. See pidi olema siis kui on selline sõidiviis STOP & GO ehk lühikesed otsad linnas, siis ei jõua filtrit puhastada. Siis kui sõidad vähemalt 10 km pidi mootori aju seadistama ümber nii, et väljalaskes temperatuur tõuseb ja põletab tahmasst puhtaks. Proovin uuesti üles leida selle jutu ja siia COPY/PASTE.Alfonze kirjutas:
Ahjaa, ja kui vaatad 05a mudelit siis sellel ka particle filter, mis pole just odav lõbu ja selle eluiga on max 200k km, niiet seda tasuks uurida ennem, kas vahetatud jne. Ilmselt on ka võimalik see muidugi vahelt lihtsalt minema visata, aga krt teab.
Kui vahelt ära visata siis ajus, vähemalt sellel millel proovisime tekkis väljalaskesüsteemi rõhuanduri viga(liiga väike vastusurve).
For heavy vehicles such as the E60, to comply with the EU4 legislation taking effect as of 2005, a coated diesel particulate filter is necessary.
This diesel particulate filter separates the soot particles in the exhaust gas with high efficiency (> 95 %). The diesel particulate filter has no influence on the nitrogen oxide (NOx) emissions; these are reduced by measures inside the engine.
The particulate filter system used at BMW requires no maintenance and is designed to last the service life of the vehicle. A fuel additive for filter regeneration is not necessary for BMW vehicles.
The diesel particulate filter is fitted close to the engine and is located behind the oxidation catalytic converter in the underbody of the vehicle.
The filter element consists of a ceramic monolith made of silicon carbide that is resistant to high temperatures. The filter element is 50 % porous and has been given a platinum-based, catalytic coating. This coating ensures that the soot ignition temperature is reduced, thus ensuring good regeneration characteristics of the particulate filter.
The total weight of the diesel particulate filter is approx. 7.5 kg.
Changes for the particulate filter system
For the actual function of the diesel particulate filter, the following changes have been added:
Exhaust system with catalytic coated soot particle filter
Throttle valve for exhaust gas temperature increase within the engine
Two exhaust gas temperature sensors per row for initiating the filter regeneration (Note:) On the M47TÜ2 engine, there is only one exhaust gas temperature sensor - before the particulate filter)
An exhaust backpressure sensor to estimate the filter load while the vehicle is being driven
Extended software of the engine management system
Use
The diesel particulate filter is deployed as follows:
E60 with M57TÜ/EU4: From 03/04
E60 with M57TÜ TOP/EU4: From 09/04
E65 with M57TÜ2: From 03/05
