Impilo ende yesevisi yokupholisa
Kunzima ukukukholelwa, kodwa ngamaphesenti angama-34 kuphela. amandla atholakala ekushisweni kwengxube ye-fuel-air aguqulwa abe amandla awusizo, okungukuthi amandla omshini. Lesi sibalo sibonisa, ngakolunye uhlangothi, ukuthi kuphansi kangakanani ukusebenza kahle kwenjini yemoto, kanti ngakolunye uhlangothi, angakanani amandla asetshenziswa ekukhiqizeni ukushisa. Eyakamuva kufanele ihlakazwe ngokushesha ukuze kuvinjwe ukushisa ngokweqile futhi ngaleyo ndlela kugxumeke injini.
Amanzi e-Glycol
Ukuze injini yemoto iphole ngendlela efanele, kuyadingeka ukusebenzisa into ekwazi ukumunca kahle bese ikhipha amandla amakhulu ashisayo uwayise ngaphandle. Ngeke kube, isibonelo, amanzi, ngoba ngenxa yezakhiwo zayo (iqhwa ku-0 degrees C futhi ibilisa ngo-100 degrees C), isusa ngokungafanele ukushisa okudlulele ohlelweni. Ngakho-ke, izinhlelo zokupholisa izimoto zisebenzisa ingxube ye-50/50 yamanzi ne-monoethylene glycol. Ingxube enjalo ibonakala ngephuzu lokuqandisa -37 degrees C kanye nephuzu elibilayo lika-108 degrees C. Iphutha elivamile ukusebenzisa i-glycol eyodwa. Kungani? Kuvela ukuthi-ke amathuba okukhipha ukushisa okuphumelelayo ayawohloka, ngaphandle kwalokho, i-glycol engaxutshwe iqhwa emazingeni okushisa angama-13 degrees C kuphela. Ngakho-ke, ukusetshenziswa kwe-glycol ehlanzekile kungabangela ukushisa kwenjini, okungaholela ngisho nasekubanjweni. . Ukuze uthole imiphumela engcono kakhulu, hlanganisa i-glycol namanzi acwecwe ngesilinganiso se-1: 1.
Nge-corrosion inhibitors
Ongoti banaka ubumsulwa bezinto ezisetshenziswa ukupholisa injini. Okokuqala, sikhuluma ngokuhlanzeka kwe-glycol. Ukusetshenziswa kokugcina kwekhwalithi ephansi kunomthelela ekwakhekeni kwe-foci of corrosion ohlelweni lokupholisa (ngenxa yokwakhiwa kwama-acidic compounds). Isici esibaluleke kakhulu sekhwalithi ye-glycol ukuba khona kwalokho okubizwa ngokuthi ama-corrosion inhibitors. Indima yabo eyinhloko ukuvikela uhlelo lokupholisa kukho kokubili ukugqwala kanye nokwakheka kwamadiphozithi ayingozi. Ama-Corrosion inhibitors aphinde avikele isipholile ekugugeni ngaphambi kwesikhathi. Kufanele kushintshwe kangaki okokupholisa kuma-radiator emoto? Konke kuncike kumkhiqizi kanye nezithasiselo ezisetshenziswa kuzo - zakudala noma eziphilayo.
Iminyaka emibili kuya kweyisithupha
Ama-coolants alula kakhulu aqukethe izithasiselo zakudala ezifana nama-silicates, ama-phosphates noma ama-borates. Ukungalungi kwabo ukuncipha ngokushesha kwezakhiwo zokuzivikela kanye nokwakhiwa kwamadiphozi ohlelweni. Ngalawa manzi, kunconywa ukuthi ushintshe ngisho njalo eminyakeni emibili. Isimo sihlukile ngoketshezi oluqukethe izinto eziphilayo (okuthiwa izinhlanganisela ze-carboxylic), ezaziwa nangokuthi uketshezi lwempilo ende. Isenzo sabo sisekelwe kumphumela we-catalytic. Lezi zinhlanganisela aziphenduli ngensimbi, kodwa ziyilamula kuphela. Ngenxa yalokhu, bangakwazi ukuvikela kangcono uhlelo ekwakhiweni kwezikhungo zokugqwala. Endabeni yoketshezi olunempilo ende yenkonzo, impilo yabo yenkonzo ichazwa njengeminyaka eyisithupha, noma cishe izinkulungwane ezingama-250. km run.
Ukuvikelwa nokungathathi hlangothi
Izinto ezipholile ezingcono kakhulu ezinezinhlanganisela ze-organic carbon azigcini nje ngokuvikela isistimu engozini yokugqwala, kodwa futhi zivimbela ukwakheka kwamadiphozithi ayingozi aphazamisa inqubo yokupholisa. Lawa manzi aphinde anciphise ngempumelelo amagesi aneasidi angaphuma angangena kusistimu yokupholisa esuka egumbini elivuthayo. Ngesikhathi esifanayo, okubalulekile futhi, abaphenduli ngepulasitiki nama-elastomers asetshenziswa ezinhlelweni zokupholisa izimoto zanamuhla. Uketshezi olunezithasiselo eziphilayo lungcono kakhulu ekuvimbeleni ubungozi bokushisa kwenjini kunozakwabo bamaminerali, ngakho-ke baya ngokuya bethatha indawo yakamuva.
