GPF sefa - yakasiyana sei neDPF?

Mafirita eGPF ari kuramba achionekwa mumotokari nyowani dzine injini dzepeturu. Ichi chinenge chishandiso chakafanana neDPF, chine basa rakafanana, asi rinoshanda mumamiriro akasiyana. Naizvozvo, hachisi chokwadi chose kuti GPF yakafanana neDPF. 

Mukuita, kubvira 2018, anenge ese mugadziri aifanira kushongedza mota ine injini yepeturu ine yakananga jekiseni remafuta nemudziyo wakadaro. Simba rerudzi urwu rinogadzira mota dzepeturu dzine mari yakawanda saka dzinoburitsa CO2 shoma.  Rumwe rutivi rwemari kuburitsa kwakanyanya kwechinhu chinonzi chin’ai. Uyu ndiwo mutengo watinofanira kubhadhara hupfumi hwemotokari dzemazuva ano uye kurwisana necarbon dioxide.

Particulate matter ine muchetura zvakanyanya uye inokuvadza kune zvipenyu, ndosaka maEmission standards eEuro 6 uye pamusoro achigara achideredza zvirimo mumagasi emhepo. Kune vanogadzira mota, imwe yeyakachipa uye inoshanda zvakanyanya kugadzirisa dambudziko ndeyekuisa GPF mafirita. 

GPF inomirira zita rechirungu kuti gasoline particulate filter. Zita rechiGerman ndiro Ottopartikelfilter (OPF). Aya mazita akafanana neDPF (Diesel Particulate Filter kana German Dieselpartikelfilter). Chinangwa chekushandisa chakafananawo - chidimbu chesefa chakagadzirirwa kuteya soot kubva kumagasi ekupedza uye kuunganidza mukati. Mushure mekunge sefa yazadzwa, soot inopiswa kubva mukati mesefa kuburikidza neyakakodzera simba system control process. 

Musiyano mukuru pakati peDPF neGPF

Uye pano tinouya kumusiyano mukuru, i.e. kune kushanda kwesefa mumamiriro ezvinhu chaiwo. Zvakanaka injini dzepeturu dzinoshanda saizvozvo exhaust magasi ane tembiricha yepamusoro. Nekuda kweizvozvo, iyo nzira yekupisa soot pachayo inogona kushomeka, nekuti. kare panguva yekushanda kwakajairika, soot inobviswa zvishoma kubva kuGPF sefa. Izvi hazvidi kuomesesa sezviri kuitika kuDPF. Kunyangwe muguta, GPF inopisa zvakabudirira, chero iyo nyeredzi & yekumisa system isiri kushanda. 

Musiyano wechipiri uri mukufamba kwemaitiro ari pamusoro apa. Mudhiziri, inotangwa nekupa mafuta akawanda kupfuura anogona kupisa injini. Kuwedzera kwaro kunobva kumasilinda kuenda kune exhaust system, kwainopisa semugumisiro wekushisa kwepamusoro, uye nokudaro inogadzira kupisa kwakanyanya muDPF pachayo. Izvi zvinobva zvapisa soot. 

Muinjini yepeturu, maitiro ekupisa soot anoitika nenzira yekuti musanganiswa wemafuta-mweya unoreruka, izvo zvinogadzira tembiricha yakanyanya yekupedza gasi pane yakajairika. Izvi zvinobvisa soot kubva musefa. 

Musiyano uyu uripo pakati peinonzi DPF neGPF filter regeneration process wakakosha zvekuti kana iri injini yedhiziri, kuita uku kunowanzotadza. mafuta akawandisa achipinda murubrication system. Diesel mafuta anosanganiswa nemafuta, anoideredza, inoshandura kuumbwa kwayo uye kwete chete kuwedzera chiyero, asiwo inofumura injini kuwedzera kukakavara. Hapana chikonzero chekuwedzera mafuta akawandisa kune injini yepeturu, asi kunyange ipapo peturu ichakurumidza kubuda kubva mumafuta. 

Izvi zvinoratidza kuti maGPF achave mashoma ekunetsa kune vatyairi pane maDPF. Izvo zvakakosha kuwedzera kuti mainjiniya einjini uye avo echaust gasi kurapwa masisitimu atove nawo anopfuura makore makumi maviri echiitiko mune dizeli particulate mafirita uye izvi zvimiro zvakaoma. Parizvino, kusimba kwavo, kunyangwe kushanda mumamiriro ezvinhu asina kunaka (kunyangwe kudzvanywa kwejekiseni) kupfuura kare, kwakakwira zvakanyanya kupfuura mukutanga kwema2000s. 

Chii chingava chinetso?

Icho chaicho chekushandisa GPF sefa. Kudzvinyirirwa kwejekiseni rakakwirira, musanganiswa wakaonda uye kusawirirana kwakashata (musanganiswa uripo nguva pfupi isati yabatidzwa) inoita kuti injini yejekiseni yakananga ibudise tunhu tunhu, kusiyana neinjini isina kunanga jekiseni isingaite. Kushanda mumamiriro ezvinhu akadaro kunoreva kuti injini pachayo uye zvikamu zvayo zvinoiswa pasi pekukurumidza kupfeka, mitoro yakakwirira yemafuta, kuzvidzora kuzvidzora kwemafuta. Zvichitaurwa zviri nyore, injini dzepeturu dzinoda sefa yeGPF dzinowanzo "kuzviparadza" sechinangwa chavo chikuru kugadzira CO2 shoma sezvinobvira. 

Saka wadii kushandisa indirect injection?

Pano tinodzokera kune kwakabva dambudziko - CO2 emissions. Kana pasina munhu ainetseka pamusoro pekuwedzera kushandiswa kwemafuta uye naizvozvo CO2 kushandiswa, izvi zvingasava dambudziko. Zvinosuruvarisa, pane zvirambidzo zvinoiswa kune vanogadzira mota. Pamusoro pezvo, injini dzejekiseni dzisina kunanga hadzina kunyatsoshanda uye dzakasiyana-siyana semajekiseni akananga. Nekufanana kwemafuta ekushandisa, havakwanisi kupa maitiro akafanana - simba guru, torque pane yakaderera revs. Kune rumwe rutivi, vatengi vashoma uye vashoma vanofarira injini dzisina simba uye dzisina mari.

Kutaura chokwadi, kana iwe usingade matambudziko neGPF uye jekiseni rakananga paunenge uchitenga mota nyowani, enda kune mota yemuguta ine diki unit kana Mitsubishi SUV. Kutengesa mota dzemhando iyi kunoratidza kuti vashoma vanhu vanoshinga kuita kudaro. Kunyangwe zvinonzwika sekunge zvakaoma, vatengi ndivo vane mhosva.
