Isihlungi samafutha.
Isihlungi sikawoyela, esaziwa nangokuthi igridi kawoyela. Isetshenziselwa ukususa ukungcola okunjengothuli, izinhlayiya zensimbi, i-carbon precipitates kanye nezinhlayiya ze-soot emafutheni ukuvikela injini.
Isihlungi sikawoyela sinokugeleza okugcwele kanye nohlobo lwe-shunt. Isihlungi esigcwele ngokugcwele sixhunywe ochungechungeni phakathi kwephampu kawoyela kanye nephaseji likawoyela eliyinhloko, ngakho-ke singakwazi ukuhlunga wonke uwoyela wokugcoba ongena ephasejini elikhulu likawoyela. Isicoci se-shunt sihambisana nephaseji eliyinhloko likawoyela, futhi ingxenye kuphela yamafutha okugcoba athunyelwa yiphampu kawoyela yesihlungi iyahlungwa.
Ngesikhathi sokusebenza kwenjini, izinsalela zensimbi, uthuli, i-carbon deposits oxidized at high temperatures, sediments colloidal, namanzi kuhlala kuxutshwa namafutha okugcoba. Indima yesihlungi sikawoyela ukuhlunga lokhu kungcola okusemishinini kanye ne-glia, ukugcina uwoyela wokugcoba uhlanzekile, nokwelula impilo yawo yesevisi. Isihlungi samafutha kufanele sibe namandla okuhlunga aqinile, ukumelana nokugeleza okuncane, impilo ende yenkonzo nezinye izakhiwo. Isistimu yokugcoba evamile ifakwe izihlungi eziningana ezinamandla ahlukene okuhlunga - isihlungi somqoqi, isihlungi esimahhadla nesihlungi esihle, ngokulandelanayo ngokuhambisana noma uchungechunge ephasejini elikhulu likawoyela. (Isihlungi esigcwele ngokugcwele esiwuchungechunge esinephaseji kawoyela esiyinhloko sibizwa, futhi amafutha okugcoba ahlungwa ngesihlungi lapho injini isebenza; Ngokuhambisana nayo ibizwa ngokuthi isihlungi se-shunt). Isihlungi esimahhadla sixhunywe kuchungechunge ephasejini elikhulu likawoyela ukuze ligeleze ngokugcwele; Isihlungi esihle si-shunt ngokuhambisana ephasejini elikhulu likawoyela. Izinjini zesimanje zezimoto ngokuvamile zinezihlungi zokuqoqa kanye nesihlungi sikawoyela esigeleza ngokugcwele. Isihlungi esimahhadla sisusa ukungcola emafutheni ngosayizi wezinhlayiyana ezingaphezu kuka-0.05mm, futhi isihlungi esihle sisetshenziselwa ukuhlunga ukungcola okuhle ngosayizi wezinhlayiyana ezingaphezu kuka-0.001mm.
● Iphepha lokuhlunga: Isihlungi sikawoyela sinezidingo eziphakeme zephepha lokuhlunga kunesihlungi somoya, ikakhulukazi ngenxa yokuthi izinga lokushisa lamafutha liyahlukahluka kusuka ku-0 kuya ku-300 degrees, futhi ukugxila kwamafutha nakho kushintsha ngokufanele ngaphansi kokushintsha kwezinga lokushisa okunamandla, okuzothinta. ukugeleza kokuhlunga kwamafutha. Iphepha lesihlungi lesihlungi sikawoyela sekhwalithi ephezulu kufanele likwazi ukuhlunga ukungcola ngaphansi kwezinguquko ezinzima zokushisa ngenkathi liqinisekisa ukugeleza okwanele.
● Indandatho yophawu lwerabha: Indandatho yesihlungi samafutha ekhwalithi ephezulu yenziwe ngerabha ekhethekile ukuqinisekisa ukuthi u-100% akukho ukuvuza kwamafutha.
● I-valve yokucindezela yokubuyisela: Izihlungi zikawoyela zekhwalithi ephezulu kuphela ezitholakalayo. Lapho injini icishiwe, ingavimbela isisefo sikawoyela ukuba singomi; Lapho injini ivuselelwe, idala umfutho ngokushesha futhi inikeze uwoyela wokugcoba injini. (eyaziwa nangokuthi i-valve yokubuyisela)
● Ivalvu yokukhulula: Izihlungi zikawoyela zekhwalithi ephezulu kuphela ezitholakalayo. Lapho izinga lokushisa langaphandle lehla libe inani elithile noma lapho isihlungi sikawoyela sidlula umkhawulo wokuphila wesevisi evamile, i-valve yokukhulula ivula ngaphansi kokucindezela okukhethekile, okuvumela uwoyela ongahlungiwe ukuba ugeleze ngqo enjinini. Noma kunjalo, ukungcola okukuwoyela kuzongena ndawonye enjinini, kodwa umonakalo uncane kakhulu kunomonakalo obangelwa ukungabikho kukawoyela enjinini. Ngakho-ke, i-valve yokusiza iyisihluthulelo sokuvikela injini esimweni esiphuthumayo. (eyaziwa nangokuthi i-bypass valve)
Ngaphansi kwezimo ezijwayelekile, izingxenye ezihlukahlukene zenjini zigcotshwa ngamafutha ukuze kufezwe umsebenzi ojwayelekile, kodwa imfucumfucu yensimbi eyenziwa ngesikhathi sokusebenza kwezingxenye, uthuli lungena, idiphozithi ye-carbon oxidized ekushiseni okuphezulu kanye nomhwamuko othile wamanzi uzoqhubeka nokuba khona. exutshwe emafutheni, impilo yesevisi yamafutha izoncishiswa isikhathi eside, futhi ukusebenza okujwayelekile kwenjini kungase kuthinteke ezimweni ezimbi kakhulu.
Ngakho-ke, indima yesihlungi samafutha ibonakala ngalesi sikhathi. Kalula nje, indima yesihlungi sikawoyela ngokuyinhloko ukuhlunga ukungcola okuningi emafutheni, ukugcina uwoyela uhlanzekile, nokwelula impilo yawo yesevisi evamile. Ngaphezu kwalokho, isihlungi samafutha kufanele futhi sibe namandla okuhlunga aqinile, ukumelana nokugeleza okuphansi, impilo ende yenkonzo nezinye izakhiwo.
Isihlungi sikawoyela kufanele sishintshwe kangaki
Umjikelezo wokushintsha isihlungi sikawoyela uvame ukufana nomjikelezo wokushintsha uwoyela, kuye ngohlobo lwamafutha asetshenziswayo. Ngenjwayelo:
Amafutha amaminerali: 5000 km noma isigamu sonyaka ukuze athathe indawo yesihlungi sikawoyela namafutha.
Amafutha e-semi-synthetic: 7500 km noma izinyanga ezingu-7-8 ukuze athathe indawo yesihlungi sikawoyela namafutha.
Amafutha okwenziwa ngokugcwele: 10000 km noma shintsha isihlungi sikawoyela namafutha kanye ngonyaka.
Ngaphezu kwalokho, amanye amamodeli noma abakhiqizi bangase babe nezincomo ezithile zokushintshwa, njengesincomo esisemthethweni se-Great Wall Haval H6 sokushintsha isihlungi sikawoyela njalo ngamakhilomitha ayi-6,000 noma isigamu sonyaka. Ngakho-ke, ekusebenzeni kwangempela, kungcono kakhulu ukubhekisela kumanuwali okugcinwa kwemoto noma uxhumane nochwepheshe wezobuchwepheshe ukuze uthole iseluleko esinembe kakhulu somjikelezo wokubuyisela.
Ngokuvamile, umjikelezo wokubuyisela esikhundleni sokuhlunga uwoyela kufanele unqunywe ngokuya ngohlobo lwamafutha, ukusetshenziswa kwemoto kanye nezincomo zomkhiqizi ukuze kuqinisekiswe ukusebenza kahle kwenjini nokwelula impilo yesevisi yenjini.
