Particulate Filter - chii? Pakuberekwa kutsva of particulate firita

Cars, kureva avo chiutsi magasi dzinotyisidzira kukuru kwezvakatipoteredza. Naizvozvo, motokari vagadziri vakatanga kushongedzera motokari yavo catalysts siyana. Uye kana iri motokari pamwe peturu injini uye inonzi zvakadaro, iri diesels - a particulate firita. Chii eremendi ichi? Chii chiri marongerwo uye nokushanda kwadzinoita? Zvose izvi uye kwete chete - gare gare munyaya ino.

sarudzo

Diesel particulate Sefa nokuti akanatsa chiutsi magasi chin'ai inoramba. Kushandisa chaikosha ichi munyika chiutsi ino kuderedza kabhoni dema zviri 95 muzana. The yokupedzisira achiumbwa nokuda kukwana combustion. Kukura kabhoni nezvimedu matema anobva 1 kusvika 0.01 microns. It rinoumbwa oxides zvesimbi, mvura, sarufa, uye carbonaceous yeimwe. chikamu muzana rwavo runotsamira kuitika nokukurumidza uye mutoro uri injini.

waigara

Iyo muchina anoiswa particulate firita? "Volkswagen", "Audi", "Mercedes". Ichi chinhu kukwana mazita mota dziri vakapakata maatomu akafanana izvi. On mutakurwi motokari Diesel particulate filters vakanga kuiswa muna 2000, pamwe chete kushanda kwezvakatipoteredza zvinodiwa "Euro-2" kana yepamusorosoro. In European Union Munyika, kuvapo tiwedzere ichi chinodikanwa kunyange motokari kubva 2011.

nzvimbo

Aripiko Diesel particulate firita? "Mercedes" uye vakawanda motokari kugadzirwa Europe vane urongwa nokuva gombedzero. Riri chete seri chiutsi zvawanda. nzvimbo iyi imhaka munzvimbo ino gasi tembiricha zvasvika vaifanira unhu.

Kweguyo musimboti oparesheni

The chikuru chinhu pamusoro Diesel particulate Sefa - a zvedongo chizvaro. Zvinonzi zvakagadzirwa nesilicon carbide. Mashoko akafanana akashandiswa catalysts ose peturu injini. Chizvaro anoiswa simbi Sefa pekugara uye ane pajira riya chimiro ne rave kuvharwa masero. The lateral Chikamu ichocho - porous. It anoita somunhu firita. Masero tiwedzere chizvaro - mativi chimiro. Pane motokari kupfuura ano kuisa filters pamwe 8-kabhoni masero. Kwakadaro zvinhu vanoonekwa zvikuru hwakavimbika uye yakareba akapfuura chiutsi magasi.

filtration Matanho

Filtration uye patsva - maererano nheyo iyi inoshanda ose particulate firita. Chii? Mupise - ndiwo neurongwa kupambwa chakagadzirwa chin'ai nezvimedu mimwe subsidence pamadziro. The makuru ndivo, zvinova nyore kushanda nokuva gombedzero. Zvisinei, kuti chiutsi magasi vane chikamu chiduku yakaisvonaka kabhoni mutema, kusvikira 1 micron. Zviri ivo vari nengozi huru zvakatipoteredza uye yemweya yevanhu.

Onawo kuti vane nguva imwe Diesel particulate Sefa ( "Renault Master TDI» - hapana Kunze) iri tsinga uye anofanira kutsiviwa. Asi nekuda kwemitengo (kubva $ 400), Russian motokari varidzi "rakacherwa" kwake "pfungwa" pamusoro kombiyuta akaisa yaro panzvimbo "spacer" - chicherwa mutopota zvakafanana dhayamita.

Pusa patsva particulate firita

oparesheni Izvi kuitwa mukuru tembiricha (500 Celsius). Ndokusaka tiwedzere iri akagadzawo zvakananga shure ari chiutsi zvawanda. Rakapinza muruoko particulate Sefa, kuti chiutsi magasi (kureva, senitrogen yeimwe) kuti sei pamwe okisijeni, nokudaro zvichiumba senitrogen dioxide. Last, unobatanidza pamwe kabhoni vatema dzikwanise oxide uye carbon monoxide. Okupedzisira maviri zvinoriumba kuita pamwe okisijeni rwakakamukana senitrogen uye carbon dioxide gasi. Izvi zvinoitika mupise muitiro chiutsi gasi ane Diesel motokari.

Under zvimwe injini anodawo zvinhu chin'ai muunganidzwa kunogona kuva va neudhadha. Iye chinyararire ichipfuura kunze muchitokisi. Pakadaro, ari kushingaira patsva zviri particulate Sefa zvakabatana kushanda.

vachishingaira

kugadzira ichi inomanikidzwa kukwidza chiutsi gasi tembiricha. Izvi zvinoitika zvose mukati pfupi nguva. Pane nzira dzakawanda kumanikidzwa tembiricha kuwedzera:

• The akazotevera mafuta jekiseni.
• Microwave kudziyisa magasi.
• The jekiseni peturu kuti Diesel particulate firita.
• Kugadzwa wemagetsi hita.

Structure neutralizer akaramba hwakavandudzika uye zvino kuonekwa inonyanya kufarirwa mhando Sefa ane CATALYTIC unhani uye kwegadziriro yokuvirisa kupinda mafuta chiyamuro. Ngationgororei navo zvizere.

CATALYTIC particulate firita

Chii eremendi ichi? Sefa ichi rinoshandiswa pamusoro motokari yemhuri "Volkswagen". Nheyo kushanda zvinosanganisira vanoshingaira uye pusa patsva.

Mukupera nyaya, kubudiswa kunoitika kuburikidza kuramba oxidation kuti chin'ai nokuda tiwedzere - Platinum, panopinda magasi zvakaitika. Kushanda tembiricha - kubva 300 kusvika 500 Celsius. Active muitiro ndepana dzakakwirira kutonhora - 650 Celsius.

Kana masimba iri kusashanda ari muzvizhinji kuti sensors. Izvi mhepo flowmeter sensors Inlet uye Outlet chiutsi gasi tembiricha uye kumanikidzwa, sezvamakaropafadzwa particulate firita unoshanda. Chii anopa? All akagamuchira date chinogadzirwa ne kombiyuta, mauri nokudzora chikwata anopa chiratidzo akazotevera mafuta Inlet, kana akazoita chekubuda mhepo mumba. Saizvozvo yekudyidzana kunowedzera chiutsi gasi tembiricha, ivo vakaitei nemashoko nokuva gombedzero zvinhu.

Filter pamwe Inzwa Zvinotaurwa chirungiso maitiro

Nokuva gombedzero yakataurwa French mainjiniya uye yakaiswa kuti "Peugeot" motokari, "Citroën", uyewo "Ford" uye "Toyota". Chimwe zita nokuti Diesel particulate Sefa - FAP. Musimboti kuvhiyiwa kuri nyore. The kwava chirungiso pamwe chete CATALYTIC convert (cerium), izvo akawedzera kuti mafuta, uye zvinoita kuti kuchinja chin'ai combustion tembiricha (vanenge 500 Celsius). Zvisinei, panguva yakaderera mitoro, zvakaoma kuwana, saka basa zvakabatana kumanikidzwa patsva. Pacharo kunochengetwa ari oga chirungiso tangi (4-5 litres).

upenyu Its anenge zviuru 100 makiromita, uye kwakafanana ari firita. Muna tangi, chirungiso iri kudirwa wemagetsi pombi. Zvinonzi dosed nechimwe refueling chinotsva zvemagetsi kudzora chikwata. The chikuru drawback ino - panguva combustion kubva necesium rakachengetedzwa pamadziro muchimiro nemadota, iyo clogs zvikuru firita. Naizvozvo, ine duku nguva kushanda zvakadaro.

How kuwedzera lifespan?

Sezvo chin'ai kurukutika ndepana dzakakwirira tembiricha upenyu pabasa Sefa kunoenderana kakawanda kokutsva-kuburikidza. Saka, chii zvinowanzoitika oparesheni ichi, vashoma Resource maatomu akafanana. Asi iwe unogona sei kuwedzera mileage mumotokari pakati pomoto ari convert? Pane yokuvirisa siyana kudzivirira particulate firita. Vanobatsira kuderedza ayo uchishandisa tembiricha kubva 600 kusvika 400 Celsius. Shandisa muchina panguva yakaderera mitoro tariro kuti chin'ai unopfuta hakuitiki, chinongova maturo. Nokuti zviitiko izvozvo, akapa kumanikidzwa patsva - kunyange nemutengo kumhanya ari chikwata achaita anoshanda 100 muzana.

Sei kuona blockage?

Zviratidzo munhu plugged Sefa zviri nyore kuona. Iri simba raidiwa, kweutsi chiutsi mutopota, kurirwa peturu. zvakadaro zvinhu vanowanzova munzvimbo chekawo anotarisa chaizvo serinofananidzirwa pazasi.

Muchiitiko chino, yaida kuti apindire - kuritsiva hutsva (chii ungangova kutungamirirwa yedu motokari varidzi) kana kubviswa kubva hurongwa.

mhedziso

Saka, takawana kuti tiwedzere ane Diesel. Sezvaunogona kuona, mudziyo wakanaka kurwa chin'ai okuchenesa. Zvisinei, zvose zvakanaka vakarasika kana yokutsiva nguva yasvika. Mari chinhu chitsva chiri anenge 50-80 zviuru rubles.
Saka nzira yakanakisisa - kubviswa particulate Sefa ari combiyta uye kugadzwa munzvimbo yayo murazvo arrester uye nyore simbi chubhu. Zvinofanira kuva nzira kubva 5 kusvika 15 zviuru rubles.
