Boemo ba ho sebetsa le molao-motheo oa fan ea pholileng ea koloi: Sistimi ea ho futhumatsa koloi e kenyelletsa mefuta e 'meli.
Pholiso ea metsi le ho pholisa moea.Mokhoa o pholileng oa koloi e pholileng ka metsi o potoloha mokelikeli ka liphaephe le likanale tse ka enjeneng.Ha mokelikeli o phalla ka har'a enjene e chesang, o monya mocheso ebe o pholisa enjene.Ka mor'a hore mokelikeli o fete ka har'a enjene, o fetisetsoa ho mocheso oa mocheso (kapa radiator), oo mocheso o tsoang ho mokelikeli o qhalloang moeeng.Ho pholisa moea Likoloi tse ling tsa pele li ne li sebelisa theknoloji ea ho pholisa moea, empa likoloi tsa sejoale-joale ha li sebelise mokhoa ona.Ho e-na le ho potoloha mokelikeli ka enjeneng, mokhoa ona oa ho pholisa o sebelisa lishiti tsa aluminium tse khomaretsoeng holim'a lisilindara tsa enjene ho li pholisa.Li-fan tse matla li bululela moea ka har'a maqephe a aluminium, li lahlela mocheso moeeng o se nang letho, o pholisa enjene.Hobane likoloi tse ngata li sebelisa pholileng ea metsi, likoloi tsa ductwork li na le liphaephe tse ngata tsamaisong ea tsona ea ho pholisa.
Ka mor'a hore pompo e fane ka mokelikeli ho thibela enjene, mokelikeli o qala ho phalla ka har'a likanale tsa enjene ho potoloha cylinder.Joale mokelikeli o khutlela thermostat ka hlooho ea silindara ea enjene, moo e tsoang teng.Haeba thermostat e tingoa, mokelikeli o tla phalla ka ho toba pompong ka liphaephe tse potolohileng thermostat.Haeba thermostat e buletsoe, mokelikeli o tla qala ho phalla ka har'a radiator ebe o khutlela pompong.
Mokhoa oa ho futhumatsa o boetse o na le potoloho e arohaneng.Potoloho e qala ka har'a hlooho ea silinda ebe e fepa mokelikeli ka maqhubu a futhumatsang pele a khutlela pompong.Bakeng sa likoloi tse nang le li-transmission tsa othomathike, hangata ho na le ts'ebetso e arohaneng ea potoloho ho pholisa oli ea phetiso e hahiloeng ka har'a radiator.Oli ea phetiso e pompeloa ke phetiso ka mochini o mong oa mocheso ho radiator.Mokelikeli o ka sebetsa ka har'a mocheso o pharalletseng ho tloha ka tlase ho likhato tsa Celsius ho ea holimo ho likhato tse 38 tsa Celsius.
Ka hona, mokelikeli ofe kapa ofe o sebelisetsoang ho pholisa enjene e tlameha ho ba le sebaka se tlaase haholo sa leqhoa, sebaka se belang se phahameng haholo, ’me se khone ho monya mefuta e mengata ea mocheso.Metsi ke e 'ngoe ea lino tse sebetsang hantle haholo ho monya mocheso, empa sebaka sa leqhoa sa metsi se phahame haholo ho fihlela maemo a teng bakeng sa lienjine tsa makoloi.Mokelikeli o sebelisoang ke likoloi tse ngata ke motsoako oa metsi le ethylene glycol (c2h6o2), e tsejoang hape e le pholiso.Ka ho eketsa ethylene glycol metsing, ntlha e belang e ka eketseha haholo 'me ntlha ea leqhoa ea theoha.
Nako le nako ha enjene e sebetsa, pompo e potoloha mokelikeli.Ho tšoana le lipompo tsa centrifugal tse sebelisoang likoloing, ha pompo e ntse e bilika, e pompa metsi ka ntle ka matla a centrifugal 'me e lula e e monya bohareng.Ho kenella ha pompo ho haufi le bohareng e le hore mokelikeli o khutlang ho tsoa ho radiator o ka kopana le mahare a pompo.Mahare a pompo a isa mokelikeli ka ntle ho pompo, moo o kenang enjene.Mokelikeli o tsoang pompong o qala ho phalla ka har'a sebaka sa enjene le hlooho, ebe o kena ka har'a radiator, 'me qetellong o khutlela pompong.Enjene cylinder block le hlooho li na le likanale tse 'maloa tse entsoeng ka ho lahla kapa tlhahiso ea mochini ho tsamaisa phallo ea mokelikeli.
Haeba mokelikeli o ka liphaepheng tsena o phalla hantle, ke feela mokelikeli o amanang le phala o tla pholile ka ho toba.Mocheso o fetisitsoeng ho tloha mokelikeli o phallang ka phala ho phala ho itšetlehile ka phapang ea mocheso pakeng tsa phala le mokelikeli o amang phala.Ka hona, haeba mokelikeli o amanang le phala o pholile ka potlako, mocheso o fetisitsoeng o tla ba o monyenyane haholo.Mokelikeli o mong le o mong o ka har'a phala o ka sebelisoa ka katleho ka ho baka moferefere phapeng, ho kopanya mokelikeli oohle, le ho boloka mokelikeli o kopane le phaephe ka mocheso o phahameng ho monya mocheso o mongata.
Pholiso ea phetisetso e tšoana haholo le radiator ka radiator, ntle le hore oli ha e fapanyetsane mocheso le 'mele oa moea, empa e na le antifreeze ho radiator.Sekoaelo sa tanka ea khatello Sekoaelo sa tanka ea khatello se ka eketsa ntlha e belang ea antifreeze ka 25℃.
Mosebetsi oa bohlokoa oa thermostat ke ho futhumatsa enjene kapele le ho boloka mocheso o sa fetoheng.Sena se finyelloa ka ho lokisa palo ea metsi a phallang ka radiator.Ha lithempereichara li le tlase, mochini oa radiator o tla koaloa ka botlalo, ho bolelang hore antifreeze eohle e tla potoloha ka enjene.Hang ha mocheso oa antifreeze o nyolohela ho 82-91 C, thermostat e tla buloa, e tla lumella mokelikeli ho phalla ka radiator.Ha mocheso oa antifreeze o fihla ho 93-103 ℃, molaoli oa mocheso o tla lula o le teng.
Fene e pholileng e tšoana le thermostat, kahoo e tlameha ho lokisoa ho boloka enjene e le mocheso o sa khaotseng.Likoloi tse ka pele tsa mabili li na le li-fan tsa motlakase hobane hangata enjene e behiloe ka holimo, ho bolelang hore tlhahiso ea enjene e shebane le lehlakore la koloi.
