Isebenza kanjani isistimu yokupholisa imoto?
Wake wacabanga ngeqiniso lokuthi izinkulungwane zokuqhuma zenzeka enjinini yakho? Uma ufana nabantu abaningi, lo mcabango awufiki engqondweni yakho. Ngaso sonke isikhathi uma i-spark plug ivutha, ingxube yomoya/yephethiloli kuleyo silinda iyaqhuma. Lokhu kwenzeka izikhathi ezingamakhulu isilinda ngomzuzu. Ungacabanga ukuthi ikhipha ukushisa okungakanani?
Lezi ziqhumane zincane uma kuqhathaniswa, kodwa ngobuningi bazo zikhiqiza ukushisa okukhulu. Cabanga ngezinga lokushisa le-ambient elingu-70 degrees. Uma injini "ibanda" ngamadigri angu-70, kuzothatha isikhathi esingakanani iqalile yonke injini ukufudumeza izinga lokushisa lokusebenza? Kuthatha imizuzu embalwa kuphela uma ungenzi lutho. Ungasusa kanjani ukushisa okweqile okukhiqizwa ngesikhathi somlilo?
Kunezinhlobo ezimbili zezinhlelo zokupholisa ezisetshenziswa ezimotweni. Izinjini ezipholile emoyeni azivamile ukusetshenziswa ezimotweni zanamuhla, kodwa zazidumile ekuqaleni kwekhulu lamashumi amabili. Zisasetshenziswa kabanzi kumagandaganda asengadini nasezinsizeni zasengadini. Izinjini ezipholiswe ngoketshezi zisetshenziswa cishe yibo bonke abakhiqizi bezimoto emhlabeni jikelele. Lapha sizokhuluma ngezinjini ezipholiswe uketshezi.
Izinjini ezipholiswe ngoketshezi zisebenzisa izingxenye ezimbalwa ezijwayelekile:
- Impompo yamanzi
- umphikisi
- Isipholisanjini
- I-Thermostat
- Ijakhethi yokupholisa injini
- I-heater eyinhloko
Isistimu ngayinye inamapayipi nama-valve atholakala futhi ahanjiswa ngendlela ehlukile. Izisekelo zihlala zifana.
Uhlelo lokupholisa lugcwele ingxube ye-50/50 ye-ethylene glycol namanzi. Lolu ketshezi lubizwa ngokuthi i-antifreeze noma isipholile. Lena indlela esetshenziswa isistimu yokupholisa ukususa ukushisa kwenjini nokukuhlakaza. I-antifreeze icindezelwa ohlelweni lokupholisa njengoba ukushisa kwandisa uketshezi kuze kufike ku-15 psi. Uma ingcindezi ingaphezu kuka-15 psi, ivalvu yokukhulula kukepisi yerediyetha iyavula futhi ikhiphe inani elincane lokupholisa ukuze kugcinwe ukucindezela okuphephile.
Izinjini zisebenza kahle ku-190-210 degrees Fahrenheit. Lapho izinga lokushisa likhuphuka futhi lidlula izinga lokushisa elizinzile lama-degrees angu-240, ukushisa kungenzeka. Lokhu kungalimaza injini nezingxenye zesistimu yokupholisa.
Impompo yamanzi: Iphampu yamanzi iqhutshwa ibhande elinezimbambo ezingu-V, ibhande elinamazinyo noma iketango. Iqukethe i-impeller ejikeleza i-antifreeze ohlelweni lokupholisa. Ngenxa yokuthi ishayelwa ibhande elixhunywe kwezinye izinhlelo zenjini, ukugeleza kwayo kuhlale kukhuphuka cishe ngesilinganiso esifanayo ne-RPM yenjini.
Isipholisanjini: I-antifreeze izungeza isuka empompini yamanzi iye kurediyetha. I-radiator iyisistimu yeshubhu evumela i-antifreeze enendawo enkulu ukuze ikhiphe ukushisa okuqukethe. Umoya udluliswa noma uphephethwa isiphephetha-moya esipholile bese ukhipha ukushisa oketshezini.
I-Thermostat: Isitobhi esilandelayo se-antifreeze injini. Isango okufanele lidlule kulo yi-thermostat. Kuze kube yilapho injini ifudumala ifinyelela izinga lokushisa elisebenzayo, i-thermostat ihlala ivaliwe futhi ayikuvumeli okupholisayo ukuthi kujikeleze enjinini. Ngemva kokufinyelela izinga lokushisa lokusebenza, i-thermostat iyavuleka futhi i-antifreeze iyaqhubeka nokujikeleza ohlelweni lokupholisa.
Injini: I-antifreeze idlula eziphasejini ezincane ezizungeze ibhulokhi yenjini, eyaziwa ngokuthi ijakhethi epholile. Isipholile sidonsa ukushisa enjinini futhi sikususe njengoba iqhubeka nendlela yayo yokujikeleza.
I-heater eyinhloko: Okulandelayo, i-antifreeze ingena ohlelweni lokushisa emotweni. I-radiator ye-heater ifakwe ngaphakathi kwekhabini, okudlula kuyo i-antifreeze. I-fan ivuthela phezu komgogodla we-heater, isuse ukushisa oketshezini ngaphakathi, bese kungena umoya ofudumele egumbini labagibeli.
Ngemva komgogodla we-heater, i-antifreeze igelezela empompini yamanzi ukuze iqale ukujikeleza futhi.
