Okokuqala, ithonya lokugeleza kwamanzi okupholisa: amanzi okupholisa anganele.I-hairpin ye-Thermostat, ukungasebenzi kahle.Iphampu ilimele noma ibhande lokuhambisa liyashelela, okubangela ukuthi iphampu isebenze kabi.
Okwesibili, umthelela wekhono lokukhipha ukushisa kuzinga lokushisa kwamanzi: irediyetha, isilinda, isilinda sebhantshi lamanzi ekhanda idiphozi isikali esikhulu, nciphisa umsebenzi wokupholisa amanzi okupholisa.Futhi ukubekwa kwesikali esiningi ebhantshini lamanzi nakho kuzobangela ukuthi ingxenye yepayipi lokujikeleza kwehle, ukuze inani lamanzi abamba iqhaza emjikelezweni wokupholisa linciphe, ngaleyo ndlela kuncishiswe ukumuncwa kwe-cylinder block, umthamo wokushisa we-cylinder head okuholela ekushiseni okuphezulu amanzi okupholisa.Umthamo we-radiator mncane kakhulu, indawo yokushisa ukushisa incane kakhulu, ithinta umphumela wokushisa ukushisa, okuholela ekushiseni okuphezulu kwamanzi.
Okwesithathu, ithonya lomthwalo wenjini ekushiseni kwamanzi.Injini kadizili ayisebenzi kahle.Overload isikhathi eside ngesivinini low, ukuze injini diesel overheating, okubangela ukushisa kwamanzi ngokweqile.
Izinsiza:
Izinzuzo zezinjini ze-diesel yi-torque enkulu nokusebenza okuhle kwezomnotho.Inqubo yokusebenza yenjini kadizili inokufana okuningi naleyo yenjini kaphethiloli.Umjikelezo ngamunye wokusebenza uphinda udlule imivimbo emine: ukuthatha, ukucindezelwa, amandla kanye ne-exhaust.Kodwa ngenxa yokuthi uphethiloli we-diesel unguphethiloli we-diesel, i-viscosity yayo inkulu kunophethiloli, akulula ukuhwamuka, futhi izinga lokushisa elizenzakalelayo lokuvutha liphansi kunophethiloli, ngakho-ke, ukwakheka nokuthungela kwengxube evuthayo kuhlukile kunenjini kaphethiloli.
Umehluko omkhulu wukuthi ingxube esesilindani senjini kadizili iyacindezelwa esikhundleni sokuvutha.Lapho injini kadizili isebenza, umoya ungena kusilinda.Lapho umoya ku-cylinder ucindezelwa kuze kube sekugcineni, izinga lokushisa lingafinyelela ku-500-700.℃futhi ingcindezi ingafinyelela kuma-atmospheres angu-40-50.
Uma ipiston iseduze nendawo ephezulu efile, umlomo womjovo wesistimu yokuphakela uwoyela ujova uphethiloli endaweni evuthayo yesilinda ngokucindezela okukhulu kakhulu ngesikhathi esifushane kakhulu.Amafutha edizili enza izinhlayiya zikawoyela ezinhle, ezixutshwe nomoya wokucindezela okukhulu kanye nokushisa okuphezulu.Ingxube evuthayo izishisa yodwa, futhi amandla aqhumayo adalwa ukwanda okunodlame, okuphusha iphiston ukuthi lenze umsebenzi liye phansi.Ingcindezi ifinyelela kuma-atmospheres angama-60-100 futhi i-torque iphezulu kakhulu, ngakho-ke injini ye-diesel isetshenziswa kakhulu emishinini emikhulu ye-diesel.
Izici zenjini yendabuko ye-diesel: ukusebenza kahle kokushisa kanye nomnotho kungcono, injini ye-diesel isebenzisa umoya ocindezelwe ukuthuthukisa izinga lokushisa lomoya, ukuze izinga lokushisa lomoya lidlule iphuzu lokuvutha okuzenzakalelayo likaphethiloli we-diesel, bese lijova kuphethiloli we-diesel, i-diesel spray. kanye ne-air mix ngesikhathi esifanayo ukuvutha kwabo komlilo.Ngenxa yalokho, izinjini zikadizili azidingi isistimu yokuthungela.
Ngesikhathi esifanayo, i-diesel fuel supply system ilula, ngakho-ke ukwethembeka kwezinjini ze-diesel kungcono kunezinjini zikaphethiloli.Injini kadizili inezinga eliphezulu lokucindezela ngenxa yokuthi ayinqunyelwe ukonakala kanye nesidingo sokuvutha okuzenzakalelayo kukadizili.Ukusebenza kahle kwe-thermal kanye nomnotho kungcono kunenjini kaphethiloli, ngesikhathi esifanayo esimweni samandla afanayo, i-torque ye-diesel injini inkulu, isivinini samandla esiphezulu siphansi, silungele ukusetshenziswa kwamaloli.
