Diesel particulate filters. Kudomwa mudziyo, kuti uchishandisa pfungwa

Pakatanga mitemo matsva zvezvakatipoteredza motokari kumanikidzira vagadziri vava yepamusoro ruzivo dzinoita zvigadzirwa zvavo zvinoenderana nemitemo. chido kwakadaro nokuda chidzoke mhuri yose injini inoratidza yakaderera-achine kugadzira zvinhu. Basa iri mberi dzimwe nzvimbo. Saka, muna 2004 pakava Diesel particulate Sefa kuti waanodzikisira choutsi dzinokuvadza. Kunyange zvazvo panguva kwayo zvakanga zvisina kudaro chaizvo kudiwa, Developers vakapfuurira kukudziridza pfungwa, uye nhasi, maererano "Euro 5" mureza, Kuwanikwa mudziyo mumotokari zvakagadzirwa kunotodiwa.

Nei kudiwa particulate firita?

Mano kwakadai nzira aftertreatment kuti chiutsi magasi. Pakarepo zvinofanira kucherechedzwa kuti Diesel particulate filters inoshandiswa Diesel injini chete. The peturu vamapoka analogue anoita se anowedzera. Chinangwa chikuru chemusha installation ndiko kubvisa chepfu kubva pedza. Kwakadaro processing magasi uye kunoita motokari zvikuru zvakatipoteredza noushamwari. Filters zvingave zvakasiyana pamusoro mudziyo, asi yavanobata basa kuderedza chin'ai tigutsikane mu chiutsi waivako kubudikidza 80%.

Zvinosuruvarisa Implementation kuti basa iri rinobatanidza zvakawanda zvimwe zvinetso, zvizhinji izvo chokuita ndichigadzira firita pachayo. Sezvo gasi kugadzira midziyo kwakasvibiswa uye kunoda okuchenesa. Muzviitiko, kuti particulate filters vanobviswa uye kuiswa kwavo panzvimbo itsva zvinoriumba aftertreatment.

The firita mudziyo

The anovhara anoiswa shure ari CATALYTIC convert. Vamwe filters kunopa zvakasiyana ayo STRUCTURAL akabatana oxidation tiwedzere. Muzviitiko zvakadaro riri seri chiutsi siyana, apo pane kunonyanyisa gasi tembiricha. The chikuru chezvinonhuwira chizvaro anoiswa simbi casing. Mureza mhando nayo chakagadzirwa nesilicon carbide, inova vakasiyana cellular maumbirwo duku muchinjikwa chikamu makwara. Chaizvoizvo, porous nemamiriro divi masvingo ari hova idzi uye rinopa kucheneswa. Pazvese, kuti Diesel particulate Sefa ndiyo chete chikamu rose siyana hurongwa uye mano munyaya Workflow. In boka iri kunosanganisirawo tembiricha sensors, simba Unit, puranga kombiyuta, mumwe turbocharger uye t. D. Chimwe chinhu ndechokuti Sefa anoita yokupedzisira yokuchenesa nerevane saka anogona kunzi ndicho chinhu chinokosha, sezvo noxious zvokurimisa mumuviri okunze.

musimboti oparesheni

The yose muitiro unogona kukamurwa muzvikamu zviviri - zvakananga Implementation rokuchenesa uye chin'ai patsva. In wokutanga danho carbon dema nezvimedu vakavharirwa, uye ipapo iiswe pamusoro firita pamadziro. Panyaya iyi, kupfuura matambudziko vari nezvimedu diki kusvika 1 micron, sezvo avo pasi uremu kunodzivisa kuvharirwa. Nepo nhamba dzakadaro zvinhu ndiyo 5 chete% of yose, ndivo chete kupfuura ngozi vanhu. Zvisinei, mazuva ano particulate filters vachikubvumira zvinobudirira kushandisa uye kubudiswa inoramba yakadaro. Second Danho patsva iri rakachengetedzwa zvinhu. Chokwadi kuti kuwanda kwavo akawanda kwete chete anokuvadza anozviti Sefa, asi kunoderedza injini simba rikava chipingamupinyi kuti ndima inotevera gasi. Panyaya iyi, matanho okuchenesa chin'ai mano ndivo fanira chikamu motokari basa.

Pusa firita kuchenesa

Izvi mhando kurapwa vari chinozoiswa nokuda yakakwirira chiutsi gasi tembiricha inogona kusvika 600 ° C. Rumwe rudzi pusa patsva nzira iri kusuma yokuvirisa siyana kupinda huni kuitira vakarongeka combustion kuti chin'ai. Muchiitiko ichi zvakare, kune simba tembiricha, asi pane imwe pamwero 400-500 ° C. Track muoti anobvumira chafariz mugumisiro Switch particulate Sefa, izvo anodzora uye vamwe parameters ari injini. Zvisinei, mune zvimwe motokari anodawo zvinhu, pusa mupise maturo kana hazviiti.

Active firita kuchenesa

Izvi kumanikidzwa nzira kuchenesa Sefa, iyo yakavakirwa hunokosha kumusoro tembiricha chiutsi gasi ezvinhu. Kuunganidza kuramba ezvinhu akadaro chin'ai ukapisa zvishoma nezvishoma. Kukosha kushingaira okuchenesa - nzira dzinosvika dzakakwirira tembiricha. Pakati rakajairika nzira iri voga kunopera mafuta jekiseni, kugoverwa Diesel chiutsi sitiroko uye kudziyisa kubudikidza microwaves. Mune zvimwe zviitiko, kuchenesa Diesel PARTICIPLE Sefa anowanikwawo yemagetsi hita. Mudziyo anogona kuiswa pedyo rokutsvaira mudziyo, asi asati configuration ichi zvinofanira kufungwa kunyatsoongorora vakagovera yenhengo dzayo. rinoita kupora iri kukwanisa pamwe rubatsiro sensors - chaizvoizvo, midziyo inoshandiswa kuyera kumanikidzwa uye tembiricha.

How kubvisa particulate firita?

Pasinei nokushandiswa ano yokuzvinatsa mugadziriro, filters iyi mhando tichikufunga kutanga kupindira nokushanda injini. Izvi inoratidzwa chin'ai accumulations dzisina kubviswa akapa nzira. The goho ezvinhu izvi zvinogona dismantling mudziyo. Uye chiitiko ichi rinoitwa mumatanho maviri. Yokutanga Chinyorwa mashandiro rinoitwa, panguva iyo namambo mumwe chete dzakaparara zvakananga particulate firita. Mutengo nzira zvichisiyana 7 kusvika 12 zviuru. Kwiza nechekuzasi. Nenzira, kugadzwa imwe Sefa itsva vanofungidzirwa 30-40 zviuru. Kwiza nechekuzasi., Saka shoma angatsunga apedzise kuvandudzwa yacho rokuchenesa hurongwa. Danho rechipiri inoumbwa nokubvisa mudziyo Software kuburikidza rewriting injini kudzora chikwata.

mhedziso

kwezvakatipoteredza mitemo Developers toreva motokari, Chokwadi, nehanya nezveramangwana revanhu uye kutsvaka dzokumabvazuva vaburitsi pamusoro kutungamirirwa kupfuura kuda mune mashoko nezvainoita zvakatipoteredza. The yokupedzisira yemudzimu imwe nzvimbo idzi uye kuva particulate filters kuti kuderedza kukuvadza kukanganisa zvakatipoteredza. Mukuita kudaro, vatyairi vacho pamwe mutsva kuisa yakawanda nematambudziko. Zvakakwana kutaura kudiwa dzose richiona nezvezvabuda kubudirira firita patsva. Kana kukwana kuzvidzora yokuchenesa mano muridzi motokari asina sarudzo asi kubvisa chinhu chinogumbura kana kutsiva naro firita itsva. Asi vacho mari vachava hakudzivisiki.
