Ko mota yekutonhodza system inoshanda sei?
Wakambofunga nezve chokwadi chekuti zviuru zvekuputika kunoitika muinjini yako? Kana iwe wakafanana nevanhu vazhinji, pfungwa iyi haimbopindi mumusoro mako. Pese panobatidzwa spark plug, musanganiswa wemhepo/mafuta mucylinder iyoyo unoputika. Izvi zvinoitika kazana pa silinda paminiti. Unogona here kufungidzira kuti inoburitsa kupisa kwakadii?
Izvi zvinoputika zvishoma, asi muhuwandu hunobudisa kupisa kwakanyanya. Funga nezve ambient tembiricha ye70 degrees. Kana injini "inotonhora" pa70 madhigirii, inguva yakareba sei mushure mekutanga injini yese ichadziya kusvika kune tembiricha yekushandisa? Zvinongotora maminetsi mashoma pasina kuita. Nzira yekubvisa sei kupisa kwakanyanya kunogadzirwa panguva yekupisa?
Kune mhando mbiri dzekutonhodza masisitimu anoshandiswa mumotokari. Injini dzemhepo-yakatonhorera hazviwanzo kushandiswa mumotokari dzemazuva ano, asi dzaive dzakakurumbira mukutanga kwezana remakore rechimakumi maviri. Dzichiri kushandiswa zvakanyanya mumatarakita egadheni nemidziyo yekurima. Liquid-yakatonhorera injini dzinoshandiswa chete nevagadziri vese vemotokari pasirese. Pano tichataura pamusoro pemvura-yakatonhorera injini.
Liquid-yakatonhorera injini dzinoshandisa mashoma akajairika zvikamu:
- Pombi yemvura
- antifreeze
- Radiator
- Thermostat
- Injini inotonhorera bhachi
- Core heater
Imwe neimwe sisitimu ine zvakare hoses uye mavharuvhu anowanikwa uye anofambiswa zvakasiyana. Nheyo dzinoramba dzakafanana.
Iyo yekutonhora inozadzwa ne50/50 musanganiswa we ethylene glycol nemvura. Mvura iyi inonzi antifreeze kana kuti inotonhorera. Iyi ndiyo svikiro inoshandiswa neinotonhodza system kubvisa injini kupisa uye kuibvisa. Antifreeze inomanikidzwa mumhepo yekutonhora sezvo kupisa kunowedzera mvura kusvika ku15 psi. Kana dzvinyiriro ichipfuura 15 psi, vharafu yekuyamura iri muvhavha yeredhiyeta inovhura uye inodzinga shoma shoma yekutonhodza kuchengetedza kudzvanywa kwakachengeteka.
Injini dzinoshanda zvakanaka pa190-210 madhigirii Fahrenheit. Kana tembiricha ichikwira uye ichipfuura tembiricha yakagadzikana ye240 madhigirii, kupisa kunogona kuitika. Izvi zvinogona kukuvadza injini uye kutonhora system zvikamu.
Pombi yemvura: Pombi yemvura inotyairwa nebhandi reV-ribbed, bhandi remazino kana cheni. Iine impeller inotenderera antifreeze mumhepo inotonhora. Nekuti inofambiswa nebhandi rakabatanidzwa kune mamwe masisitimu einjini, kuyerera kwayo kunogara kuchiwedzera muchikamu chakafanana neinjini RPM.
Radiator: Antifreeze inotenderera kubva papombi yemvura kuenda kune radiator. Radiator ichubhu system inobvumira antifreeze ine nzvimbo yakakura yepasi kuti ipe kupisa kwairi. Mhepo inopfuudzwa kana kupeperetswa nefeni inotonhorera uye inobvisa kupisa kubva mumvura.
Thermostat: Iyo inotevera kumira kweantifreeze ndiyo injini. Gedhi raanofanira kupinda naro ndiro thermostat. Kusvikira injini yadziya kusvika pakushanda tembiricha, iyo thermostat inoramba yakavharwa uye haibvumire inotonhorera kutenderera kuburikidza neinjini. Mushure mekusvika tembiricha yekushanda, thermostat inovhura uye antifreeze inoramba ichitenderera mumhepo yekutonhora.
Injini: Iyo antifreeze inopfuura nemumigero madiki akatenderedza injini block, inozivikanwa sebhachi rinotonhorera. Iyo inotonhorera inotora kupisa kubva mujini uye inoibvisa apo inoenderera mberi nenzira yayo yekutenderera.
Core heater: Tevere, iyo antifreeze inopinda mukudziya system mumotokari. A heater radiator inoiswa mukati mekabhini, iyo iyo antifreeze inopfuura. Iyo fan inovhuvhuta pamusoro pepakati pehita, ichibvisa kupisa kubva mumvura mukati, uye mweya unodziya unopinda mukamuri yevafambi.
Mushure mekupisa kwepakati, antifreeze inoyerera ichienda kune pombi yemvura kuti itange kutenderera zvakare.
