Inzwa yokushisa yenjini - yini okudingeka ukwazi mayelana nokusebenza kwayo okufanele? Yiziphi izimpawu zokulimala kwezinzwa?

Inzwa yezinga lokushisa lenjini - iyithola kanjani idatha? Umgomo wokusebenza

Inzwa yezinga lokushisa lenjini itholakala ku-cylinder block, ngokuthintana ngqo nesipholile. Ngezinye izikhathi ibizwa ngokuthi inzwa yamanzi noma izinga lokushisa elipholile. Umsebenzi wayo ukuthumela ukufundwa njalo kukhompyutha ukuze idlulise amanani athile. Umgomo wokusebenza kwalesi sici ungase ubonakale uyinkimbinkimbi kancane lapho uqala nje, kodwa sizozama ukuwuchaza kancane.

Ukusebenza kwenzwa echazwe kusekelwe ku-coefficient yezinga lokushisa elibi. Lokhu kusho ukuthi ukumelana kwangaphakathi kuncipha njengoba ukushisa koketshezi olujikelezayo ku-cylinder block kukhula. Isimo siyashintsha lapho izinga lokushisa lemvelo lehla. Ngemva kokuthola inani elithile lokumelana, isilawuli silayisha ulwazi olwanele kuso mayelana nezinga lokushisa lenjini. Izinga ngalinye likagesi lihambisana nenani elithile ngamadigri Celsius. Ngenxa yalokhu, ikhompuyutha "iyazi" ukuthi injini ifudumele kangakanani nokuthi kufanele ilungise kanjani umthamo wamafutha ezimweni zamanje ezishisayo kuyunithi.

Kungani ukala izinga lokushisa lenjini?

Njengoba amayunithi omlilo edinga kakhulu uphethiloli, umoya namafutha ukuze asebenze, kungani sidinga ukwazi inani lokushisisa kwesipholile? Impendulo ilula kakhulu: inzwa yokushisa yenjini inomthelela oqondile kwikhwalithi yeyunithi, futhi izinga layo lokushisa lithinta nezinye izingxenye. Ngaphandle kokuqapha izinga lokushisa lamanje, isilawuli semitha kaphethiloli singahlala sinothisa umthamo, okungaholela ekwenyukeni kwezinga lokusha nokushisisa ngokweqile kwenjini.

Ngaphezu kwalokho, amanzi aphezulu kakhulu noma amazinga okushisa apholile ayingozi enjinini. Ngokuvamile igijima ku-90 kuya ku-100.^oC. Ukweqa leli nani kuholela ekubilisweni kwe-medium, okuthi kamuva (kuye ngokuthi imodeli yemoto) kungaholela ekulimaleni kwe-cylinder head gasket.

Izimpawu nezizathu zokushintsha inzwa yokushisa kwamanzi

Ukushintsha le elementi ngentsha ngokuvamile kwenzeka ngenxa yezizathu ezimbili:

• walimala
• umsebenzisi ufuna ukuyikhipha ohlwini lwezingxenye ezinesici.

Konke lokhu kungenxa yokuthi inzwa yokushisa kwamanzi ivame ukunikeza izimpawu ezingacacile. Bangadideka, isibonelo, ngemitha yokugeleza eyonakele, ibhethri efile, noma isistimu yokunikezela uphethiloli eyonakele. Bheka nje amasiginali athunyelwa kakhulu ngendlela yokuthi:

• ukwanda kwenani lama-revolution ngesikhathi sokungenzi lutho,
• ukwanda kokusetshenziswa kukaphethiloli,
• inkinga ukuqala iyunithi.

Uyavuma ukuthi lezi zimpawu azifani nengxenye ethile yemoto. Ngakho-ke, ukulimala kwenzwa yokushisa kwamanzi kuyinkathazo futhi kungase kudukise, ngakho ukuxilongwa okufanele kuthatha isikhathi.

Yiqiniso, ngesikhathi esinjalo ungase ucabange ukuthi kungaba kuhle ukuxhuma ikhompyutha yokuxilonga emotweni. Ngeshwa, nakulesi sigaba, ungabona amakhodi amaphutha asho ukuthi, isibonelo:

• izinguquko zesignali ezingachazwanga,
• ukuhlanganisa okufushane,
• i-wire break,
• inzwa yesifunda esifushane
• izinga lokushisa elincane alikwazi ukufinyelelwa.

I-thermostat eyonakele inemiphumela efanayo. Khona-ke kusenzima ukunquma ukuthi inzwa encane yokushisa kwamanzi inecala ekusebenzeni okungalungile kwenjini. Kodwa-ke, kwezinye izimo kungenzeka ukukhipha ngokuphelele noma uqinisekise ukulimala kwayo.

Indlela yokuhlola inzwa yokushisa yenjini engalungile?

Nokho, ngezinye izikhathi konke kubonisa ukuthi le nzwa ihlulekile enjinini. Okokuqala, bheka kahle nxazonke. Hlola uxhumo, isimo sokufakelwa, izintambo, ama-kink okungenzeka, yinqamule kupulaki futhi ubheke izimpawu zokugqwala. Kungase kuvele ukuthi inzwa yokushisa yenjini ayilimazi nhlobo, kodwa igcwele uketshezi noma enye into, futhi othintana nabo kufanele bahlanzwe.

Uma zonke lezi zinqubo ezingenhla zingalethi umphumela olindelekile, kufanele ulungele ukushintsha yonke into. Kwenziwa kanjani?

Esusa inzwa yokushisa epholisayo

Okokuqala, uzodinga inzwa entsha. Inani elifanele lokupholisa lizophinde libe usizo, ngoba ukufaka esikhundleni lesi sakhi kuhlale kuhlotshaniswa nokulahlekelwa kwesipholile. Inzwa yokushisa kwamanzi ishintshwa kangcono enjinini ebandayo. Abukho ubungozi bokusha okuvela ezingxenyeni zeyunithi noma uketshezi oluzophuma.

Okulandelayo, susa into eyonakele. Qala ngokukhipha intambo kupulaki. Khumula ngokucophelela inzwa usebenzisa isikrufu esihlinzekelwe le njongo. Khipha into entsha endaweni efanayo bese ugcwalisa injini ngenani elifanele loketshezi olusha. Ungakhohlwa ukufaka umoya ngendlela efanele.

Okudingayo ama-wrenches ambalwa, uketshezi olusha, nomqondo ojwayelekile. Ngenxa yamathiphu angenhla, nakanjani uzokwazi ukufaka esikhundleni senzwa. Ngikufisela inhlanhla!
