Ukupholisa amanzi kuyindlela yokupholisa enomphumela omuhle wokuqeda ukushisa.Umgomo wokupholisa amanzi uwukupholisa i-cylinder liner kanye nekhanda le-cylinder ngokugoqa amanzi agelezayo.Isistimu yayo yokupholisa izoqukatha isipholile, esizozungeza kancane futhi esikhulu ezingeni lokushisa lamanje lenjini ngaphansi kokushayela kwepompo yamanzi.Le nzuzo izokwenza izinga lokushisa lenjini lilingane, ngaphandle kokusebenza ngokweqile.I-valve ye-throttle yemoto epholile ngamanzi ngeke ivule lapho izinga lokushisa liphansi;Lapho izinga lokushisa lamafutha liphezulu, i-valve ye-throttle izovuleka ngokugcwele, futhi ithangi lamanzi lizoqala ukusebenza.Uma izinga lokushisa liphezulu kakhulu, ifeni izovulwa ukuze iphole ifike ezingeni elifanele lokushisa lokusebenza kwenjini.Ilungele izithuthuthu ezinokufuduka okukhulu namandla amakhulu.Ukushisa okukhiqizwe yizithuthuthu ezinokususwa okuncane akukwazi ukupholiswa ngamanzi.

Izesekeli eziyisisekelo zokupholisa amanzi: iphampu yamanzi, ukulawulwa kwezinga lokushisa kwethangi lamanzi kanye nefeni.

Ukungalungi kokupholisa amanzi: izindleko eziphezulu, isakhiwo esiyinkimbinkimbi, izinga eliphezulu lokuhluleka, ngoba indawo ehlala ithangi lamanzi langaphandle nayo inkulu.Ukushintsha okuyimpumputhe kokupholisa amanzi akugcini nje ukuthuthukisa ukusebenza, kodwa kuzokwenza imoto eshisayo ibe yinde, imoto ebandayo igqoke kakhulu, futhi ishise amafutha enjini kusengaphambili.

Ukupholisa uwoyela kuwukusebenzisa isistimu yokuthambisa yenjini ukuqeda ukushisa ngerediyetha kawoyela.Alukho uketshezi olwengeziwe oludingekayo, futhi inqubo yokusebenza ilula.I-radiator yamafutha kanye nethangi lamanzi ngokuyisisekelo kuyisimiso esifanayo, kodwa enye ingamafutha kanti enye ingamanzi.

Izesekeli eziyisisekelo zokupholisa amafutha: ukupholisa amafutha aphansi kudinga kuphela i-radiator yamafutha, kuyilapho ukupholisa kwamafutha aphezulu kuzohlonywa abalandeli nama-throttle valves.

Izinzuzo zokupholisa amafutha: umphumela ocacile wokushisa ukushisa, izinga lokuhluleka eliphansi, izinga lokushisa eliphansi likawoyela linganciphisa i-viscosity ephezulu yamafutha.

Ukungalungi kokupholisa uwoyela: kupholisa kuphela izinga lokushisa lamafutha enjini, hhayi i-cylinder block kanye nekhanda le-cylinder, ngakho-ke umphumela wokushisa ukushisa uphakathi.Kunemikhawulo enanini likawoyela wenjini.Irediyetha ayikwazi ukuba nkulu kakhulu.Uma kukhulu kakhulu, uwoyela uzogeleza ungene kurediyetha kawoyela, okubangela ukuthambisa okunganele phansi enjini.

Ukushintsha ukusuka ekupholiseni komoya ukuya ekupholiseni uwoyela kufanele kufane nomfutho werediyetha kanye nephampu kawoyela.Umthamo werediyetha kawoyela omkhulu kakhulu awulungile ekugcotshisweni kwegiya lenjini, ukugeleza kwerediyetha okuncane kakhulu kuncane kakhulu, okuzoba nengcindezi empompini kawoyela, nokugeleza kukawoyela okwanele kuzodala ukuguga okukhulu ekhanda lesilinda.Kodwa-ke, amanye amamodeli apholile kawoyela nawo anokusebenza okuphezulu.Lolu hlobo lwenjini luzosebenzisa umklamo wesekethe kawoyela okabili, futhi i-cylinder block izoklanywa njengesimo esingenalutho, esizovumela isifunda sawoyela sokushabalalisa ukushisa ukuthi sipholise ngokuqondile i-cylinder block, ukuze umphumela wayo wokukhipha ukushisa usebenze kahle.

Ukupholisa komoya kusho ukupholiswa komoya okulethwa imoto.Amasinki amakhulu okushisa azoklanywa ebusweni besilinda senjini, futhi osinki bokushisa namapayipi omoya azoklanywa ekhanda lesilinda ukuze kwandiswe indawo yokuxhumana phakathi kwenjini nomoya.

Izinzuzo zokupholisa umoya: ukwehluleka kwesistimu yokupholisa iqanda (ukupholisa kwemvelo), izindleko eziphansi zenjini yokupholisa umoya kanye nesikhala esincane.

Ukungalungi kokupholisa komoya: ukuchithwa kokushisa kuhamba kancane futhi kunqunyelwe uhlobo lwenjini.Isibonelo, ukupholisa komoya akuvamile ukusetshenziswa kumasilinda amane akulayini, futhi amasilinda amabili aphakathi nendawo awakwazi ukuqeda ukushisa ngempumelelo.Ngakho-ke, izinjini eziningi ezipholile emoyeni zizovela ezinjinini zesilinda esisodwa noma izinjini zamasilinda ezimise okwe-V ezigcizelela ukuphuma kwetorque ephansi.Injini epholile emoyeni engenasici ekwakhiweni kwayo ayinankinga uma ihamba amabanga amade.Akushiwo ukuthi injini epholile emoyeni ayikulungele ukuhamba amabanga amade.Injini epholisa umoya ka-Harley emise okwe-V ayivamisile ukwehluleka ngenxa yokushisa kwenjini eyeqile.

Ukupholisa amanzi kuwuhlelo lokupholisa olubalulekile lwamandla amasilinda amaningi kanye nezinjini ezinesivinini esikhulu (kanye nokupholisa okukabili kukawoyela wamanzi).Izimoto ezincane eziyi-125 ezingamasilinda azilungele ukupholisa amanzi.Ngokuvamile, ukususwa kwe-125 akukhiqizi ukushisa okungaka.Ukupholisa uwoyela ukucushwa okujwayelekile kwezimoto zasemgwaqeni ezimaphakathi, okuphishekela ukuzinza nomthelela wokushisa kwabalandeli.Izimoto ezipholiswe umoya zesilinda esisodwa zifaneleka kakhulu ukushintshelwa ekupholiseni uwoyela, futhi ukuguqulwa ukusuka ezimotweni ezipholiswe yisilinda esisodwa ukuya ekupholiseni uwoyela kudinga kuphela ukwengeza isifudumezi sefeni samafutha phakathi nendawo yokuhambisa uwoyela.Ukupholisa komoya ukucushwa okujwayelekile kwezithuthuthu zansuku zonke.Izindleko zenjini ezingasebenzi kahle zesistimu yokupholisa ziphansi.Uma nje igcinwe kahle, inkinga yokushisa okuphezulu ngeke yenzeke, kodwa izinga lokushisa eliphezulu lezimoto ezipholile ngamanzi lizoba njalo.Ngamafuphi, ukupholisa umoya kwe-cylinder eyodwa yesivinini esiphansi kuyisinqumo esingcono kakhulu.
