Njengoba sazi ukuthi kuningi okuthuthukisiwe okwenziwe ezinjinini, ukusebenza kahle kwezinjini akukabi phezulu ohlelweni lokuguqula amandla amakhemikhali abe amandla emishini.Amandla amaningi kuphethiloli (cishe u-70%) aguqulwa abe ukushisa, futhi ukuqeda lokhu kushisa kuwumsebenzi wesistimu yokupholisa imoto.Eqinisweni, imoto eshayela emgwaqeni omkhulu, ukushisa okulahlekelwe yisimiso sayo sokupholisa kwanele ukushisa izindlu ezimbili ezivamile!Uma injini ibanda, izosheshisa ukuguga kwezingxenye, ngaleyo ndlela yehlise ukusebenza kahle kwenjini futhi ikhiphe ukungcola okwengeziwe.
Ngakho-ke, omunye umsebenzi obalulekile wesistimu yokupholisa ukufudumala injini ngokushesha ngangokunokwenzeka futhi uyigcine izinga lokushisa elingashintshi.Uphethiloli uvutha njalo enjini yemoto.Ukushisa okuningi okukhiqizwa ohlelweni lokuvutha kukhishwa ohlelweni lwe-exhaust, kodwa okunye ukushisa kusala enjinini, okubangela ukuba ishise.Uma izinga lokushisa lesipholisa liba ngu-93°C, injini ifinyelela esimweni sayo esingcono kakhulu sokusebenza.

Umsebenzi wokupholisa uwoyela ukupholisa uwoyela wokugcoba nokugcina izinga lokushisa likawoyela lingaphakathi kwebanga lokusebenza elivamile.Enjinini enamandla amakhulu athuthukisiwe, ngenxa yomthwalo omkhulu wokushisa, kufanele kufakwe isipholile sikawoyela.Lapho injini isebenza, i-viscosity yamafutha iba mncane ngokukhuphuka kwezinga lokushisa, okunciphisa amandla okugcoba.Ngakho-ke, ezinye izinjini zifakwe i-cooler yamafutha, umsebenzi wayo uwukunciphisa izinga lokushisa likawoyela nokugcina i-viscosity ethile yamafutha okugcoba.I-cooler yamafutha ihlelwe kumjikelezo kawoyela ojikelezayo wesistimu yokugcoba.

Izinhlobo zokupholisa uwoyela:
I-1) I-cooler yamafutha epholile emoyeni
Umnyombo we-oyela opholile opholile emoyeni wakhiwe amashubhu amaningi okupholisa namapuleti okupholisa.Lapho imoto ihamba, umoya ozayo wemoto usetshenziselwa ukupholisa i-cooler core yamafutha ashisayo.Izipholile zikawoyela ezipholiswe ngomoya zidinga umoya omuhle ozungezile.Kunzima ukuqinisekisa isikhala esanele sokungenisa umoya ezimotweni ezivamile, futhi ngokuvamile azivamile ukusetshenziswa.Lolu hlobo lwama-cooler lusetshenziswa kakhulu ezimotweni zomjaho ngenxa yejubane eliphezulu lemoto yomjaho kanye nomthamo omkhulu womoya opholile.
2) I-cooler yamafutha epholile ngamanzi
Isibandisi samafutha sifakwa endaweni yokupholisa amanzi, kanti izinga lokushisa lamanzi okupholisa lisetshenziselwa ukulawula izinga lokushisa lamafutha okugcoba.Lapho izinga lokushisa lamafutha okugcoba liphezulu, izinga lokushisa lamafutha okugcoba liyancipha ngamanzi okupholisa.Lapho injini iqaliswa, ukushisa kuthathwa emanzini apholisayo ukuze izinga lokushisa likawoyela wokugcoba likhuphuke ngokushesha.I-cooler kawoyela yenziwe ngegobolondo elenziwe nge-aluminium alloy, isembozo sangaphambili, isembozo sangemuva kanye neshubhu eliwumgogodla wethusi.Ukuze kuthuthukiswe ukupholisa, amasinki okushisa afakwa ngaphandle kweshubhu.Amanzi apholisayo ageleza ngaphandle kweshubhu, futhi uwoyela wokugcoba ugeleza ngaphakathi kweshubhu, futhi lezi ezimbili zishintshana ngokushisa.Kukhona nezakhiwo lapho uwoyela ugeleza ngaphandle kwepayipi futhi amanzi ageleza ngaphakathi kwepayipi.
