Izinga likawoyela wenjini liphezulu kakhulu. Kungani kukhona uwoyela enjinini?

Njengoba noma yimuphi umshayeli azi, izinga likawoyela eliphansi kakhulu lingabangela izinkinga eziningi zenjini. Kodwa-ke, okuphambene nakho kuya ngokuya kushiwo - lapho inani lamafutha enjini linganciphi, kodwa liyakhula. Lokhu kuyiqiniso ikakhulukazi ezimotweni zikadizili. Imiphi imiphumela? Kungani kukhona uwoyela enjinini?

Uzofundani kulokhu okuthunyelwe?

• Ikuphi inkinga ngokufaka uwoyela wenjini?
• Kungani izinga likawoyela wenjini lenyuka?
• Uwoyela oweqile enjinini - iyini ingozi?

Ngikhuluma nje

Izinga likawoyela wenjini liyakhuphuka ngokwalo lapho olunye uketshezi, olufana nesipholisi noma uphethiloli, lungena ohlelweni lokuthambisa. Umthombo walokhu kuvuza kungaba yi-cylinder head gasket (yokupholisa) noma amaringi episton avuzayo (ukuthola uphethiloli). Ezimotweni ezifakwe isisefo sezinhlayiya, ukuhlanjululwa kwamafutha ngolunye uketshezi ngokuvamile kuwumphumela wokusha okungafanele kwensiza enqwabelene esihlungini.

Kungani izinga likawoyela wenjini likhuphuka ngenkathi ushayela?

Yonke injini ishisa uwoyela. Amanye amayunithi - afana neRenault's 1.9 dCi, adume kabi ngezinkinga zawo zokugcoba - empeleni, amanye mancane kangangokuthi kunzima nokuwabona. Nokho, ngokuvamile Ukulahlekelwa inani elincane lamafutha enjini kuyinto evamile futhi akufanele kube yimbangela yokukhathazeka. Ngokuphambene nokufika kwakhe - ukukhiqizwa okufanayo okuzenzakalelayo kwe-lubricant njalo kubonisa ukungasebenzi kahle. Kungani kukhona uwoyela enjinini? Isizathu silula ukuchaza - ngoba kungena olunye uketshezi olusebenzayo kuwo.

Ukuvuza kwesipholisi sibe uwoyela

Isizathu esivame kakhulu samazinga aphezulu kawoyela wenjini yi isipholile esingena ohlelweni lokuthambisa ngegasket elimele ye-cylinder head. Lokhu kuboniswa umbala olula we-lubricant, kanye nokulahlekelwa okukhulu kokupholisa ithangi lokunweba. Nakuba isici sibonakala singenangozi futhi kulula ukusilungisa, singabiza. Ukulungisa kuhilela izakhi eziningana - umshini wokukhiya akumele ubeke esikhundleni se-gasket kuphela, kodwa ngokuvamile futhi ugaye ikhanda (lokhu okubizwa ngokuthi ukuhlelwa kwekhanda), ukuhlanza noma ukubuyisela iziqondiso, izimpawu nezihlalo ze-valve. Ukusetshenziswa? Phezulu - akuvamile ukuthi ifinyelele ama-zloty ayinkulungwane.

Isibaseli emafutheni enjini

Uphethiloli uketshezi lwesibili olungangena ohlelweni lokuthambisa. Ngokuvamile lokhu kwenzeka ezimotweni ezindala eziguge kakhulu, zombili ezinophethiloli nezinjini zikadizili. Imithombo yokuvuza: amasongo e-piston avumela uphethiloli ukuthi ungene ekamelweni elivuthayo - lapho ihlala ezindongeni ze-cylinder, bese igeleza epanini lamafutha.

Ukuba khona kukaphethiloli emafutheni enjini kulula ukukubona. Ngesikhathi esifanayo, igrisi ayishintshi umbala, njengalapho ixubene nesipholile, kodwa inakho iphunga elithile kanye noketshezi olwengeziwe, ukungaguquguquki okunamathelayo okuncane.

Ukunciphisa uwoyela wenjini ngolunye uketshezi kuzohlala kunomphumela omubi ekusebenzeni kwenjini, ngoba lokho amafutha awanikezi ukuvikeleka okwaneleikakhulukazi emkhakheni wokugcoba. Ukubukela phansi inkinga ngokushesha noma kamuva kuzoholela emonakalweni ongathi sína - kungase kuphele ngisho nokugcwala okuphelele kweyunithi yokushayela.

Ingabe unawo umshini wokuhlunga we-DPF? Qaphela!

Ezimotweni ezinenjini ye-diesel, uphethiloli, noma kunalokho uphethiloli we-diesel, ungaba ohlelweni lokugcoba ngesinye isizathu - "Ukushiswa" okungafanele kwesihlungi se-DPF. Zonke izimoto zikadizili ezakhiwe ngemuva kuka-2006 zifakwe izihlungi ze-diesel particulate, okungukuthi, izihlungi ze-diesel particulate - yilapho kwaqala ukusebenza izinga le-Euro 4, elibeka kubakhiqizi isidingo sokunciphisa ukukhishwa kwe-exhaust. Umsebenzi wezihlungi zezinhlayiya ukucupha izinhlayiya ze-soot eziphuma ohlelweni lwe-exhaust kanye namagesi e-exhaust.

Ngeshwa, i-DPF, njenganoma yisiphi isihlungi, iyavaleka ngokuhamba kwesikhathi. Ukuhlanzwa kwayo, okwaziwa ngele-"burnout" ngokuzenzakalelayo, kwenzeka ngokuzenzakalelayo. Le nqubo ilawulwa ikhompuyutha esebhodini, okuthi, ngokusho kwesignali evela kuzinzwa ezifakwe kusihlungi, inikeze umthamo owengeziwe kaphethiloli ekamelweni elivuthayo. Ukweqisa kwawo akushiswa, kodwa ingena ohlelweni lwe-exhaust, lapho ivutha khona ngokuzenzakalelayo... Lokhu kuphakamisa izinga lokushisa lamagesi e-exhaust futhi kushisa ngokoqobo umule oqoqwe kusihlungi sezinhlayiya.

Isihlungi se-DPF esishisiwe namafutha amaningi enjini

Ngokombono, kuzwakala kulula. Kodwa-ke, ekusebenzeni, ukuvuselelwa kwesihlungi se-particle akusebenzi kahle ngaso sonke isikhathi. Lokhu kungenxa yokuthi izimo ezithile ziyadingeka ekusebenzeni kwayo - isivinini senjini ephezulu kanye nesivinini sokuhamba njalo sigcinwa imizuzu embalwa. Lapho umshayeli ebhuleka kakhulu noma ema erobhothini, ukutubeka kwe-soot kuyama. Uphethiloli oweqile awungeni ohlelweni lwe-exhaust, kodwa uhlala ku-cylinder, bese wehla ngezindonga ze-crankcase ungene ohlelweni lokuthambisa. Uma kwenzeka kanye noma kabili, akunankinga. Okubi nakakhulu, uma inqubo yokushiswa kwesihlungi iphazamiseka njalo - khona-ke izinga lamafutha enjini lingakhuphuka kakhulu... Isimo se-DPF kufanele sicatshangelwe ikakhulukazi ngabashayeli abashayela kakhulu edolobheni, ngoba kungaphansi kwezimo lapho ukuvuselelwa kuvame ukwehluleka.

Iyini ingozi kawoyela wenjini oweqile?

Izinga likawoyela wenjini eliphakeme kakhulu libi kakhulu emotweni yakho njengoba liphansi kakhulu. Ikakhulukazi uma i-lubricant ihlanjululwe ngolunye uketshezi - bese ilahlekelwa izici zayo futhi ayinikezi ukuvikelwa okwanele kwedivayisi yokushayela... Kodwa amafutha amaningi ahlanzekile ahlanzekile nawo angaba yingozi uma siwasebenzisa ngokweqile ngowoyela. Lokhu kubangela lokhu ukwanda kwengcindezi ohlelweniokungase konakalise noma yiziphi izimpawu zamanzi futhi kubangele ukuvuza kwenjini. Izinga eliphezulu kakhulu lokuthambisa liphinde libe nomthelela omubi ekusebenzeni kwe-crankshaft. Ezimweni ezimbi kakhulu ezimotweni ezinenjini kadizili, lokhu kungaholela nasekungasebenzi kahle okuyingozi okubizwa ngokuthi i-injini overclocking. Sabhala ngalokhu embhalweni othi: Ukusheshisa kwenjini kuyisifo esihlanyayo sikadizili. Kuyini futhi kungani ungafuni ukuzwa ngakho?

Yiqiniso, sikhuluma ngokweqile okuphawulekayo. Ukweqa umkhawulo ngamalitha angu-0,5 akufanele kuphazamise ukusebenza kwedrayivu. Wonke umshini unepani likawoyela elingabamba umthamo owengeziwe wamafutha, ngakho-ke ukungeza ngisho namalitha angu-1-2 ngokuvamile akuyona inkinga. "Ngokujwayelekile" ngoba kuncike kumodeli yemoto. Ngeshwa, abakhiqizi ababonisi ubukhulu bendawo egciniwe, ngakho-ke kusafaneleka ukunakekela izinga elifanele likawoyela enjinini. Kufanele ibhekwe njalo emahoreni angama-50 lapho ushayela.

Ukufaka uphethiloli, ukushintshwa? Izinhlobo eziphezulu zamafutha emoto, izihlungi nolunye uketshezi olusebenza ngogesi lungatholakala ku-avtotachki.com.
