Isihlungi se-GPF - sihluke kanjani ku-DPF?

Izihlungi ze-GPF ziya ngokuya zivela ezimotweni ezintsha ezinezinjini zikaphethiloli. Lokhu cishe kuyidivayisi efanayo ne-DPF, inomsebenzi ofanayo ncamashi, kodwa isebenza ezimeni ezihlukene. Ngakho-ke, akulona iqiniso ngokuphelele ukuthi i-GPF iyafana ne-DPF. 

Empeleni, kusukela ngo-2018, cishe wonke umkhiqizi kuye kwadingeka ahlomise imoto ngenjini kaphethiloli ngomjovo oqondile wamafutha ngomshini onjalo. Lolu hlobo lwamandla lwenza izimoto zikaphethiloli zonga kakhulu ngakho-ke zikhipha i-CO2 encane.  Olunye uhlangothi lwemali ukukhishwa okuphezulu kwe-particle matter, okuthiwa yi-soot. Lena inani okufanele silikhokhele umnotho wezimoto zesimanje kanye nokulwa ne-carbon dioxide.

Izinhlayiya ezinobuthi zinobuthi ngokwedlulele futhi ziyingozi ezintweni eziphilayo, yingakho amazinga okukhishwa kwe-Euro 6 nangaphezulu ngokuvamile enciphisa okuqukethwe kwawo kumagesi akhipha umoya. Kubenzi bezimoto, esinye sezixazululo ezishibhile nesisebenza ngempumelelo enkingeni ukufaka izihlungi ze-GPF. 

I-GPF imele igama lesiNgisi lesihlungi sezinhlayiyana zikaphethiloli. Igama lesiJalimane yi-Ottopartikelfilter (OPF). Lawa magama afana ne-DPF (Isihlungi Sezinhlayiya Ze-Diesel noma Isihlungi Se-German Dieselpartikelfilter). Inhloso yokusetshenziswa nayo iyafana - isihlungi sezinhlayiya siklanyelwe ukubamba umule kumagesi akhipha umoya bese uwuqoqa ngaphakathi. Ngemva kokuba isihlungi sesigcwalisiwe, umule uyashiswa kusukela ngaphakathi kwesihlungi ngenqubo efanele yokulawula uhlelo lwamandla. 

Umehluko omkhulu phakathi kwe-DPF ne-GPF

Futhi lapha sifika umehluko omkhulu, i.e. ekusebenzeni kwesihlungi ezimeni zangempela. Kahle kahle izinjini zikaphethroli zisebenza kanjalo amagesi e-exhaust anezinga lokushisa eliphakeme. Ngenxa yalokho, inqubo yokutubeka kwe-soot ngokwayo ingase ingabi njalo, ngoba. kakade ngesikhathi sokusebenza okuvamile, umsizi ukhishwa kancane kusihlungi se-GPF. Lokhu akudingi izimo eziqinile njengaku-DPF. Nasedolobheni iGPF isha ngempumelelo, inqobo nje uma inkanyezi nesistimu yokumisa ingasebenzi. 

Umehluko wesibili usekuhambeni kwale nqubo engenhla. Kudizili, iqalwa ngokuhlinzeka ngophethiloli ongaphezu kwalokho ongashiswa yinjini. Ukweqisa kwayo kusuka kumasilinda kuya ohlelweni lokukhipha umoya, lapho ishisa khona ngenxa yokushisa okuphezulu, futhi ngaleyo ndlela kudala izinga lokushisa eliphezulu ku-DPF ngokwayo. Lokhu-ke kushisa umule. 

Enjinini kaphethiloli, inqubo yokushiswa kwe-soot yenzeka ngendlela yokuthi ingxube ye-fuel-air ithambile, okudala izinga lokushisa eliphakeme kakhulu legesi yokukhipha umoya kunangaphansi kwezimo ezijwayelekile. Lokhu kususa umule kusihlungi. 

Lo mehluko phakathi kwenqubo ebizwa ngokuthi i-DPF ne-GPF filter regeneration ubaluleke kakhulu kangangokuthi uma kuyinjini ye-diesel, le nqubo ivame ukuhluleka. uphethiloli oweqile ongena ohlelweni lokugcoba. Uphethiloli we-diesel uxuba namafutha, uyawunciphisa, ushintsha ukwakheka kwawo futhi ungagcini nje ngokukhulisa izinga, kodwa futhi udalula injini ekukhuphuleni ukungqubuzana. Asikho isidingo sokwengeza uphethiloli oweqile enjinini kaphethiloli, kodwa nalapho uphethiloli uzohwamuka ngokushesha emafutheni. 

Lokhu kuphakamisa ukuthi ama-GPF azoba nenkinga encane kubashayeli kunama-DPF. Kufanelekile ukungeza ukuthi onjiniyela bezinjini kanye nezinhlelo zabo zokwelashwa kwegesi ephumayo sebenazo kakade ngaphezulu kweminyaka engama-20 yesipiliyoni kuzihlungi ze-diesel particulate futhi lezi yizakhiwo eziyinkimbinkimbi. Njengamanje, ukuqina kwazo, naphezu kokusebenza ngaphansi kwezimo ezingezinhle kangako (ngisho nomfutho womjovo ophakeme) kunangaphambili, kuphezulu kakhulu kunasekuqaleni kwawo-2000. 

Kungaba yini inkinga?

Lona kanye iqiniso lokusebenzisa isihlungi se-GPF. Umfutho omningi womjovo, ingxube engenawo amandla kanye nokungaguquguquki okubi (ingxube yakheka ngaphambi nje kokuvutha) kubangela injini yomjovo eqondile ukuthi ikhiqize izinhlayiya, ngokungafani nenjini yomjovo engaqondile engakwenzi. Ukusebenza ezimweni ezinjalo kusho ukuthi injini ngokwayo kanye nezingxenye zayo zingaphansi kokuguga okusheshayo, imithwalo ephezulu yokushisa, ukuzishisa okungalawuleki kukaphethiloli. Kalula nje, izinjini zikaphethiloli ezidinga isihlungi se-GPF zivame "ukuzilimaza" njengoba umgomo wazo oyinhloko uwukukhiqiza i-CO2 encane ngangokunokwenzeka. 

Pho kungani ungasebenzisi umjovo ongaqondile?

Lapha sibuyela emthonjeni wenkinga - ukukhishwa kwe-CO2. Ukube akekho onendaba nokwenyuka kokusetshenziswa kukaphethiloli ngakho-ke ukusetshenziswa kwe-CO2, lokhu bekungeke kube yinkinga. Ngeshwa, kunemikhawulo ebekwe kubakhiqizi bezimoto. Ukwengeza, izinjini zokujova ezingaqondile azisebenzi kahle noma aziguquguquki njengezinjini zomjovo oqondile. Ngokusetshenziswa okufanayo kukaphethiloli, abakwazi ukunikeza izici ezifanayo - amandla aphezulu, i-torque ngesivinini esiphansi. Ngakolunye uhlangothi, abathengi banesithakazelo kancane kancane ezinjinini ezibuthakathaka nezingenawo umnotho.

Ukulibeka ngembaba elokuthi - uma ungakufuni ukuhlupha kwe-GPF kanye nomjovo oqondile uma uthenga imoto entsha, hamba uthenge imoto encane yasedolobheni enamandla noma iMitsubishi SUV. Ukudayiswa kwezimoto zalolu hlobo kukhombisa ukuthi bambalwa kangakanani abantu abanquma ukwenza lokhu. Nakuba kungase kuzwakale kunokhahlo, amakhasimende yiwona anecala.
