Filtarrada particulate Diesel. Magacaabidda qalabka, mabda'a qalliinka

hordhaca ah ee heerarka cusub deegaanka baabuurta qasbo saarayaasha si ay u horumariyaan farsamooyinka dheeraad ah oo horumarsan in awood waxyaabaha ay u hoggaansamaan heerarka. hadafka noocan oo kale ah ay sabab u ah ee qoysaska oo dhan ee matoorada in muuqan waxyaabaha processing low-emission. Work waa in horumar meelo kale. Sidaas daraaddeed, 2004 waxaa jiray filter particulate naaftada ah in yaraynaysaa in qiiqa waxyeello. Inkasta oo waqtiga la aasaasay ma ahaa si ballaaran in dalabka, horumarinta ayaa sii waday in ay horumariyaan fikradda ah, oo maanta, sida laga soo xigtay "Euro 5" standard, helitaanka qalabka in design baabuur waa waajib.

Waa maxay sababta loo baahan yahay filter particulate ah?

Qalabka noocan ah waa hab aftertreatment of gaasas dhammayn. Isla markiiba waa in la ogaadaa in filtarrada particulate naaftada loo isticmaalo in matoorada naaftada kaliya. unugyada The shidaalka ee analoogga u dhaqmo sidii qaar kaaliya. Ujeedada ugu weyn ee la rakibo waa in meesha laga saaro walxaha sunta ah ka dhammayn. gaasas noocan oo kale ah ka baaraandegidda oo ka dhigaysa gaariga bii'ada. Filtarrada waxaa laga yaabaa kala duwan oo ku saabsan qalabka, laakiin waxay qabtaan hawsha yareeyo content danbas in qaab qaaca by 80%.

Nasiib darro, fulinta shaqo this weeyaan badan oo dhibaatooyin kale, kuwaas oo intooda badan la xidhiidha qabashada filter laftiisa. Sida qalab processing gaaska waa wasakhaysan oo u baahan nadiifinta. Xaaladaha xad-dhaaf ah, miirayaasha particulate ah la saaraa laguna rakibay meeshoodii qaybaha cusub aftertreatment.

qalab filter The

block waxaa la dhigayaa ka dambeeya Converter u horseed. filtarrada Qaar ka mid ah sidoo kale u oggolaadaan kala duwanaansho ay isku darka dhismaha la Hannaan lagu qayilo. Xaaladaha noocaas ah waxaa uu ku yaalaa ka danbeeya kala cayncayn ah dhammayn, halkaas oo ay jiraan heerkul ah gaaska ugu badnaan. component ugu weyn ee maxalka furta oo waxaa la dhigayaa sanduuqa battariga ee birta ah. The lagu daydo caadiga ah waxaa laga sameeyey oo carbide Silicon, taas oo ka-dhismeedka gacanta ee channels qaybta cross yar oo kala duwan. Dhab ahaantii, dhismaha beeniyayna derbiyada ka dhisan ee channels iyo bixisaa isdaahirinta. Muhiimsan, filter particulate naaftada ah waa qayb ka mid kaliya ee kala duwan oo dhan nidaamyada iyo qalabka ku lug aalada ah. In kooxdan ayaa sidoo kale ku lug leedahay dareemayaal heerkulka, unit xoogga, computer guddiga, turbocharger ah iyo t. D. Waxa kale oo ay tahay in filter qabanayo shaqo kama dambays ah nadiifinta oo sidaas daraaddeed waa la tixgelin karaa sida element muhiim ah, tan iyo markii uu u aabayeelin ka fulisaa xubno jirka.

Mabda 'hawlgalka

Geedi socodka oo dhan waxa loo qaybin karaa laba marxaladood - fulinta si toos ah shaandhaynta iyo danbas cusboonaysiinta. In talaabada ugu horeysa ee Qurub carbon madow ku xayirmay, ka dibna shubo on darbiyada filter ah. Marka tan la eego, ugu dhibaato waa qayb yar ilaa 1 micron, sida ay miisaanka yar yahay ka hortagtaa lagu hayo. Inkastoo saamiga xubno kale waa% wadarta kaliya 5, ay yihiin oo keliya ee ugu halista badan in ay aadanuhu. Si kastaba ha ahaatee, filtarka particulate maanta laguu ogolaado in aad si wax ku ool u maareeyaan iyo processing Qurub sida. cusboonaysiinta marxaladda labaad lagu shubo alaabta. Xaqiiqada ah in ay raasamaal ee u tiro badan ma aha oo kaliya isaga qudhiisu geystaa filter ah, laakiin sidoo kale waxay yareysaa awoodda engine sida sameynta caqabad marinkii gaaska ee soo socda. Marka tan la eego, tallaabooyin si aad u nadiifiso qalabka danbas waa qayb ka mid khasab ah adeegga gaariga.

nadiifinta filter dadban

Tani nooca daawaynta ee lagu fuliyey ay sabab u tahay heerkulka gaaska dhammayn sare oo ay gaari karaan 600 ° C. nooc kale oo habka cusboonaysiinta dadban waa in la soo bandhigo daro kala duwan galay shidaalka si loo hubiyo in sari hufan ee danbas. In this sidoo kale ay dhacdo, waxaa jira saamayn of heerkulka, laakiin heer of 400-500 ° C. mode Track ogolaanaya filter ah kaamerada shidma saamayn particulate, kaas oo gacanta ku iyo qaar ka mid ah xuduudaha ka engine ah. Si kastaba ha ahaatee, in xaaladaha hawlgalka baabuur gaar ah, shaandhaynta dadban waa faa'iido lahayn ama aan macquul ahayn.

nadiifinta filter Active

Habkan lagu qasbay in nadaafadda filter ah, kaas oo ku salaysan deegaanka gaaska dhammayn heerkulka sare ee gaarka ah. Aruursaday in dayactirka xaaladaha sida danbas si tartiib tartiib ah baabbi'iyey. Muhiimka ah ee nadiifinta firfircoon - jid gaadho heerkulka sare. Waxaa ka mid ah hababka ugu caansan waxaa go'doonsan duro shidaalka soo daahay, sahayda ee stroke naafto iyo kulaylinta by microwaves. Xaaladaha qaarkood, nadiifinta filter walxaha naaftada ah ayaa sidoo kale soo saaray kululeeyaha korontada. Qalabka lagu rakibi karo ee soo socota si ay u qalab nadiifinta, laakiin ka hor qaabeynta this waa in la tixgeliyaa si taxadar leh u geliya qaybaha. kabashada firfircoon ayaa sidoo kale maamula iyadoo ay kaalmo ka mid ah dareemayaal - gaar ahaan, qalab loo isticmaalo in lagu cabbiro cadaadiska iyo heerkulka.

Sidee in meesha laga saaro filter particulate?

Inkastoo isticmaalka nidaamka nadiifiskeeda u casri ah, miirayaasha noocan ah si degdeg ah ama waqti dambe ay bilaabaan inay faragelin hawlaha engine ah. Waxaa lagu qeexay accumulations danbas aan saaro siyaabo kala bixiyo. wax soo saarka ee xaaladaha u noqon karaan kala dhantaalay qalabka. Oo dhacdadan waxaa lagu qabtaa laba marxaladood. Hawlgalka ayaa marka hore buuggan waxaa la sameeyaa, inta lagu guda jiro taasoo kala dhantaashay filter si toos ah particulate. Qiimaha nidaamka kala duwan yihiin laga bilaabo 7 ilaa 12 kun. xoq. By habka, rakibo of filter cusub waxaa lagu qiyaasaa 30-40 kun. Xoq., Sidaas yar dhicin si ay u dhamaystiraan cusboonaysiinta nidaamka nadiifinta. Tallaabada labaad ee ka kooban ee ay ka saareen software qalabka by muqato unit gacanta engine ah.

gunaanad

horumarinta heerarka deegaanka ee la xiriirta baabuurta, dabcan, daryeel ah oo ku saabsan mustaqbalka ee aadanaha oo doonaya in ay soo saarayaasha Orient on jihada ugu dadnimo la eego saamaynta ay ku leeyihiin deegaanka. wax soo saarka ugu dambeeya ee mid ka mid ah goobahaas oo ay noqoto filtarrada particulate in la yareeyo saamaynta waxyeello on deegaanka. In sidaas la sameeyo, darawallada wada rakibo cusub oo dhibaatooyin fara badan. Waxaa ugu Filan in la xuso baahida loo qabo la socodka joogtada ah ee waxtarka dhalashadii filter ah. In case of qalab is-nadiifinta Milkiilaha gaariga ku filnayn ma lahan doorasho laakiin in meesha laga saaro block ama bedesho filter cusub. Laakiin labada kiis ee kharashka noqon doonaa lama huraan.
