I-Windshield Ifohloza Ngokushesha noma Ukufaka u-Icing NGAPHAKATHI ngesivinini somgwaqo omkhulu: I-Defrost Physics kanye nama-Heater Cores avuzayo

Izinombolo zezimo eziphuthumayo ziyehluka ngezwe. Leli khasi lisebenzisa u-911, inombolo yase-United States naseCanada. Amanye amazwe amaningi asebenzisa u-112, 999, noma enye inombolo. Thola inombolo yezwe lakini.

Driving into a cold rainstorm, mountain tunnel, or sub-zero winter morning and watching your interior windshield glass turn completely opaque white in less than 5 seconds at 110 km/h (70 mph) is as blinding as having your hood fly open. Instinctively, startled drivers reach forward with a bare hand, coat sleeve, or tissue to wipe the inside of the glass - only to smear skin oils or greasy film across the windshield, turning oncoming headlights into a blinding wall of glare - or they make the fatal climate-control mistake of turning the A/C (Air Conditioning) button OFF and pressing Recirculate ON because the cabin feels cold.

Sudden interior windshield blindness happens for one of two reasons: (1) Dew-Point Moisture Flash-Condensation (or sub-zero interior frost icing), where humid cabin air from wet coats, melted snow on floor mats, or four breathing passengers hits cold windshield glass (or the car's A/C compressor automatically shuts itself off when outside air drops below 2 degrees Celsius / 36 degrees Fahrenheit, dumping 100 percent of evaporator moisture onto the glass at once); or (2) a Ruptured Dashboard Heater Core, which sprays boiling, sweet-smelling, oily ethylene glycol antifreeze steam directly out of the defrost vents onto the inside of the glass. If you lose forward visibility in fast traffic or inhale choking chemical steam, turn on your hazard flashers, look out the side window to guide your vehicle onto the shoulder, and call your local emergency number if needed (911 in the United States and Canada, 112 across the European Union, 999 in the United Kingdom; see izinombolo eziphuthumayo) kanye nokubuyekeza Ukuxhumana okuphukile kwesisula somoya emvuleni enkulu noma isiphepho esishisayo, Ukushisisa ngokweqile kwemoto, isitimu ngaphansi kwesivalo, nokuvikelwa kwe-gasket ekhanda, futhi Izicabha zemoto ezifriziwe, izingidi namafasitela.

Yenza lokhu manje

  1. Check for a sweet "maple syrup" smell or greasy smear first (Heater Core Leak Test): Before blasting the defroster higher, take a quick sniff of the air coming from the dashboard vents.
  2. If the fog smells sweet like maple syrup or hot radiator fluid, rises as visible steam from the dash vents, and feels greasy/oily if touched, TURN THE HEATER AND BLOWER FAN COMPLETELY OFF (0) IMMEDIATELY and crack all four side windows open 5 centimeters (2 inches). Your dashboard heater core has ruptured, spraying hot, toxic ethylene glycol antifreeze vapor onto the windshield. Blasting the defroster will only coat the glass thicker and overheat your engine.
  3. For normal water-vapor fog, set the 4-Switch "Max Dehumidify" combination immediately:
  4. Switch 1 - Turn A/C (Air Conditioning) ON (Even in freezing winter): The A/C evaporator coil inside the dashboard acts as a powerful dehumidifier, chilling incoming air to condense and drain water out under the car before the heater core warms the dry air up.
  5. Switch 2 - Turn Temperature All the Way to MAX HOT (After a 10-second cool blast if in summer humidity): Hot air holds 5 to 10 times more moisture than cold air (like a dry sponge) and heats the inner glass surface above the dew point.
  6. Switch 3 - Turn Recirculate OFF (Switch to Fresh Outside Air Intake): Keeping Recirculate ON traps human breath (each person exhales 40 to 50 grams of water vapor per hour) and wet floor-mat evaporation inside a sealed loop. Outside winter air holds very little absolute moisture once heated.
  7. Switch 4 - Crack Both Rear (or Front) Side Windows Down 2 to 3 Centimeters (1 Inch): Opening two windows slightly creates a low-pressure Venturi exhaust that pulls humid cabin air out in 15 to 20 seconds - essential in sub-zero weather below -1 degree Celsius (30 degrees Fahrenheit) when your car's computer automatically disables the A/C compressor to keep the evaporator from freezing solid.
  8. Never wipe the inside of the windshield with your bare palm or fingers: Human skin oil leaves a hydrophobic smear that scatters headlight beams at night. Keep a clean, dry microfiber waffle-weave cloth, chalkboard eraser, or squeegee in the door pocket; if caught with nothing in a heater-core glycol emergency, wipe with a dry paper napkin or cotton shirt soaked in alcohol-based hand sanitizer or winter windshield washer fluid.
  9. If the inside of the windshield is covered in solid WHITE ICE in sub-zero weather: Scrape the interior glass downward with a plastic bank card or rewards card held at a 45-degree angle while catching the falling frost shavings on a towel on thedashboard, then remove wet snow-covered rubber floor mats and knock them clean outside the car.

Danger

Toxic Ethylene Glycol Inhalation and Engine Overheating Hazard From a Leaking Heater Core: Inside your dashboard sits a miniature aluminum radiator called the heater core, through which your engine pumps 95-degree-Celsius (203-degree-Fahrenheit) pressurized engine coolant (50/50 ethylene glycol antifreeze and water) whenever the engine is running. - Why Turning Defrost UP Makes a Heater-Core Leak Worse: When a heater core cracks or corrodes inside the HVAC box, turning the blower fan to MAX DEFROST blasts vaporized ethylene glycol straight onto the cold windshield glass. Unlike water, ethylene glycol boils at 197 degrees Celsius (387 degrees Fahrenheit) and never evaporates off the glass - it condenses into a sticky, rainbow-tinted, greasy film that blinds the driver while filling the enclosed cabin with toxic glycol aerosol that irritates the lungs and causes dizziness, headache, and nausea. - Immediate Action: Shut the climate-control fan completely OFF (or set temperature to MAX COLD on older cable-operated blend-door systems to close the hot coolant valve), roll down the side windows to purge the cabin air, pull onto the shoulder, and watch the engine coolant temperature gauge closely - because a leaking heater core drains the main engine cooling system and can blow the engine head gasket within minutes.

I-psychrometric physics of defrosting: Kungani kufanele usebenzise A/C ON + Full Heat + Fresh Air ndawonye

Abantu abaningi bacabanga ukucindezela i-A/C (I-Air Conditioning)* inkinobho isho "ukwenza umoya ubanda," ngakho bayenqaba ukuvula A/C ebusika - noma bacabanga ukucindezela Recirculate (inkinobho yemoto eno-U-turn-arrow) izofudumeza ikhabethe ngokushesha. Eqinisweni, ibhokisi lesimo sezulu sedeshibhodi yemoto yakho lihlela i-A/C evaporator core ebandayo FIRST kanye ne- inkimbinkimbi yeheater eshisayo SECOND ochungechungeni eduze komhubhe wokugeleza komoya. Nakhu okwenziwa iswishi ngayinye ukusula iwindshield yakho ngesikhathi esishesha kakhulu:

Ukushintsha kwesimo sezulu Isilungiselelo esilungile sokusula inkungu yangaphakathi I-physics yokuthi kungani isilungiselelo esingalungile sicupha inkungu engilazini
1. A/C (I-Air Conditioning Compressor) Inkinobho ON (Ukukhanya Kwenkomba) Umoya ophephethwa yi-fan udlula ezibandeni ezibandayo ze-A/C evaporator (3 degrees Celsius / 37 degrees Fahrenheit) OKOKUQALA. Ngenxa yokuthi umoya obandayo awukwazi ukubamba umhwamuko wamanzi, kuze kube amaphesenti angu-80 womswakama emoyeni ongenayo ujiya ngokushesha ungene emazingeni abandayo e-evaporator yensimbi bese uconsisela ngaphandle kweshubhu lokudonsa injoloba emgwaqeni ongaphansi kwemoto.
2. Ukudayela Kwezinga lokushisa / Isilayidi MAX HOT (HI) Ngokushesha ngemva kokuba i-evaporator ye-A/C ikhumule amanzi aphume emoyeni, ukuthi umoya obandayo owomile ngamathambo udlula kumongo weheater ongu-90-degree-Celsius. Ukushisisa umoya owomile wehlisa Umswakama Ohlobene (RH) ngaphansi kwamaphesenti angu-15 - ukushintsha ukugeleza komoya kube "isipontshi esiphezulu" esimunca amaconsi amanzi asuka kuwindi lomoya ngemizuzwana ngenkathi sishisisa ingilazi ngaphezu kwendawo yamazolo.
3. Ukungenisa umoya (Recirculate vs Fresh Outside Air) Recirculate OFF (Fresh Outside Air ON) Abantu abadala abane emotweni ephefumulayo ehlangene amamililitha angu-200 (cishe inkomishi engu-1) womusi wamanzi afudumele ngehora, kanye namanye amamililitha angu-300 ahwamukayo ezambulela ezimanzi, amajazi, nomata baphansi abambozwe yiqhwa. Uyahamba Recirculate ON iphinda igaye kabusha egcwale umoya womswakamo ongu-95% engilazini kaningi. Ngisho nangosuku oluna ebusika ngo 4 degrees Celsius (39 degrees Fahrenheit), umoya wangaphandle uqukethe kuphela ** amagremu angu-6 wamanzi nge-cubic meter ngayinye ** - uma ushiselwe 40 degrees Celsius, umswakama wayo ohlobene wehlela ku-11%.
4. I-Windows eseceleni I-Crack Two Windows Open 2 cm (1 inch) amasekhondi angu-60 Ngezansi 0 to 3 degrees Celsius (32 to 37 degrees Fahrenheit), ikhompuyutha yemoto ngayinye Icima ngokuyimfihlo i-compressor ye-A/C (yize iluhlaza A/C ukukhanya enkinobho kuhlala kukhanyisiwe) ukuze umhwamuko ungami ube yiqhwa eliqinile. Esimeni sezulu esingaphansi kweziro, ukuqhekeza amawindi amabili avuleke ngamasentimitha angu-2ukuphela kwendlela yokukhipha umoya omswakama ekhabetheni ngokushesha.

Kungani i-windshield yami ibe yinkungu kumasekhondi angu-2 lapho ngishayela kakade? (Izimo ezi-3 ze-Flash-Fogging)

Kwesinye isikhathi iwindshield yakho iba sobala ngokuphelele emizuzwini yokuqala engu-20 yokushayela kwakho, bese - phakathi kwe-2 kuya kumizuzwana emi-3 - yonke indawo engaphakathi yengilazi ibaneka mhlophe ngokujiya okukhulu:

  1. Isimo 1 - I 2-Degree-Celsius (36F) Ukusika kwe-A/C Compressor okuzenzakalelayo:
  2. Uqala ukushayela kusihlwa okubandayo, okuswakeme ngo 5 degrees Celsius (41 degrees Fahrenheit) nge-defroster kanye A/C egijima. Imizuzu engu-20, ikhoyili ebandayo ye-A/C evaporator iqoqa uhhafu welitha lamanzi ajiyile emaphikweni ayo e-aluminium.
  3. Njengoba ukhuphuka igquma noma ebusuku, inzwa yangaphandle yezinga lokushisa iyehla isuka 4C phansi ku 2 degrees Celsius (35.6 degrees Fahrenheit). Ukuze uvimbele amaphiko e-evaporator amanzi ukuthi angaqhwa abe yiqhwa eliqinile futhi aqhekeze umongo, ikhompuyutha yemoto inqamula amandla ku-compressor ye-A/C khona manjalo.
  4. Phakathi namasekhondi angu-10, amaphiko e-evaporator amanzi afudumala ku-airstream ye-heater, ahwamulise wonke lawo manzi agciniwe ngesikhathi esisodwa futhi aqhumise ifu elingu-100%-nomswakama womswakamo uqonde ngqo kuwindi lomoya elibandayo.
  5. Ukulungisa Ngokushesha: Hlukanisa womabili amawindi angaphambili phansi ngamasentimitha angu-3 (1.2 amayintshi) ngokushesha, qinisekisa Recirculate kuyinto OFF, bese uvula ukushisa nesiphephetha MAX imizuzwana engama-60 kuze kube yilapho i-evaporator fins yome.
  6. Isimo sesi-2 - Ukungena Kumhubhe Womgwaqo Omkhulu Ofudumele, Oswakeme ebusika (Cold Glass + Humid Tunnel Air):
  7. Ngemva kokushayela ku -10 degrees Celsius (14 degrees Fahrenheit) isikhathi esingangehora, ingilazi ye-windshield yakho ipholile -8 degrees Celsius. Uma ungena emhubheni omude ongaphansi komhlaba noma onguthelawayeka wasentabeni ogcwele igesi yemoto efudumele, enomswakama (+15 degrees Celsius), kokubili okuthi ngaphandle kanye ngaphakathi kwengilazi ebandayo kuwela ngaphansi kwendawo yamazolo emhubhe kanye kanye.
  8. Ukulungisa Ngokushesha: Qalisa iwindshield wiper (ukuze usule ukufiphala kwangaphandle) kuyilapho uqhumisa I-Max Hot Defrost ngaphakathi.
  9. Isimo sesi-3 - I-Flep Ephukile noma Ebambekile Yokuzulazula Kwezimoto Ngemva kwe-Glovebox:
  10. Emamodeli amaningi eVolkswagen, Audi, Ford, GM, Dodge/Jeep, neHonda/Toyota, igiya lepulasitiki elincane ku- fresh-air / recirculation intake flap actuator motor ngemva kweglovebox lihlubula amazinyo alo, lishiya iflephu libhajwe unomphela endaweni evaliwe. Recirculate isikhundla ngisho noma inkinobho yedeshibhodi ithi Fresh Air. Uma amawindi akho ekhungatheka kakhulu yonke idrayivu yasebusika ngaphandle kwezilungiselelo zezinkinobho, yehlisa i-glovebox phansi bese uqinisekisa ukuthi i-dome flap iyavuleka uma uguqula Recirculate inkinobho.

Ithebula lokuxilonga: Inkungu yamanzi avamile vs. I-heater core evuzayo (Ethylene Glycol) vs. Isithwathwa sangaphakathi

Sebenzisa leli thebula lokuqhathanisa ukuze ubone ukuthi yini emboze ingaphakathi le-windshield yakho phakathi nemizuzwana eyi-10:

Isici sokuxilonga I-Normal Water Vapor Condensation I-Heater Core yedeshibhodi evuzayo (I-antifreeze / Coolant) I-Sub-Zero Interior Frost / Iqhwa
Iphunga endlini Ayinaphunga (noma imdaka/imanzi kancane uma isihlungi somoya sekhabethe simanzi). "isiraphu ye-maple" ehlukile, enoshukela noma iphunga elishisayo lerediyetha eliba namandla uma uvula ukudayela kwezinga lokushisa kube HOT. Ayinaphunga, umoya obandayo obandayo.
Kwenzakalani uma uphenduka MAX DEFROST (Hot Air) VULA Inkungu iqala ukucaca kusukela phansi kwewindshield iye phezulu phakathi kwamasekhondi angu-10 kuya kwangu-30 njengoba umoya owomile oshisayo ushaya ingilazi. Inkungu iba KABI futhi iba nkulu ngokushesha - ifu elimhlophe elibonakalayo lesitimu liphuma ezikhaleni zokususa isithwathwa kudeshibhodi futhi limboza ingilazi yonke. Unqenqema olungezansi luyancibilika kancane lube amaconsi amanzi ngaphezu kwemizuzu emi-3 kuya kwemi-5 uma injini isifudumala.
Ukuma komzimba lapho wesulwa ngesicubu esihlanzekile noma ngomunwe Isula kahlenjengamanzi acwebile, anganamatheli ahwamuka emunweni wakho kumasekhondi angu-5. Ifilimu enamafutha, e-slimy, enamafutha egcoba phakathi kothingo olunqamula ingilazi futhi ngeke ihwamuke isuke eminweni yakho. Amakristalu eqhwa aqinile, aqinile adinga ikhadi lepulasitiki noma i-scraper ukuze aphuce.
**Ezinye izimpawu emotweni ** izambulela ezimanzi, amabhuzu aneqhwa, noma abagibeli abaningi emotweni; I-A/C drain ingase ivaleke. Uketshezi olumanzi, olunamathelayo oluluhlaza/opinki/owolintshi olucwilisa umata waphansi oseceleni komgibeli ngaphansi kodeshi; izinga lokupholisa eliphansi endaweni yokugcina amanzi engaphansi; ukushintshashintsha kwezinga lokushisa kwenjini. Iqhwa elimanzi elalishiywe kumata berabha phansi izolo lincibilike ngenkathi imoto ifudumele, lahwamuka emoyeni, labanda langena ngaphakathi engilazini ngobusuku bonke.

Inqubo yesimo esiphuthumayo eseceleni komgwaqo uma i-heater yedeshibhodi yakho iqhuma ngenkathi ushayela

Uma i-windshield yakho igqoke inkungu enamafutha, enephunga elimnandi evimbela ukuqhwa ngenkathi ushayela:

Isinyathelo 1: Misa i-Glycol Steam bese usula iwindi lokubuka eliphephile ukuze udonse

Warning

Kungani Ungalokothi Usule I-Windshield Ehlanganiswe I-Glycol Ngesandla Sakho Esingenalutho Noma Indwangu Eyomile: I-Ethylene glycol iyinhlanganisela ye-oily diol engashisi ekushiseni kwekamelo. Ukusula isiphephelo somoya esinenkungu ecwebezelayo ngentende yesandla sakho esingenalutho noma ngendwangu eyomile gcoba amafutha angabonakali, ahlukanisa uthingo phakathi komugqa wakho wokubona ophendula izibani zangaphambili zibe udonga oluqinile lokucwebezela. Njalo sebenzisa isincibilikisi sotshwala (hand sanitizer, rubbing alcohol, or winter windshield washer fluid) ngendwangu ehlanzekile noma ithawula lephepha ukuze ahlakaze ifilimu ye-glycol.

  1. Vula isiphephetha-moya sokulawula isimo sezulu OFF bese usetha izinga lokushisa libe MAX COLD (LO): Ukusetha izinga lokushisa libe kubanda okugcwele kuvala umnyango we-heater (futhi ezimotweni eziningi kuvala i-valve yokulawula isifudumezi samanzi ashisayo), kuvimbe umoya ukuba ungavunguzi kumongo we-heater ovuzayo.
  2. Yehlisa wonke amafasitela ezinhlangothi ezine ngamasentimitha angu-5 ukuya kwangu-8 (amayintshi angu-2 ukuya kwangu-3): Umoya omusha onqamulayo ususa inkungu ye-ethylene glycol enobuthi emaphashini akho futhi uvimbele umhwamuko ukuthi ungaminyana phezu kwefilimu ye-glycol.
  3. Donsa ngokuphepha ehlombe noma endaweni yokupaka izimoto.
  4. Indlela yokuhlanza i-ethylene glycol enamafutha isuka ngaphakathi kwe-windshield eceleni komgwaqo: Izindwangu ezomile zizodwa zigcoba isinqanda-qhwa ukusuka ngapha nangapha. Mmanzisa inabukeni ehlanzekile, ithawula lephepha, noma ihembe likakotini isicoci sesandla esisekelwe otshwaleni, ukusula izinto zotshwala, isicoci sengilazi, noma uketshezi lwewasha lwewindi lasebusika oluhlaza okwesibhakabhaka olucwiliswe endaweni yokugcina amanzi ewasha engaphansi kwehood (umshayeli we-methanol/isopropanol osusa igrisi ohlangothini lwe-zoglycemia kwesokudla), ingilazi, bese womisa ngethawula lephepha elihlanzekile.

Isinyathelo sesi-2: Hlola Ileveli Yokupholisa Injini Yakho Ngaphambi Kokushayela Elinye Ikhilomitha (Iqhinga Le-Hose-Loop Bypass)

Ngenxa yokuthi umgogodla we-heater yedeshibhodi uyingxenye yesekhethi yokupholisa enokucindezela efanayo epholisa ikhanda le-cylinder yenjini yakho, i-heater ephukile ingampompa amalitha angu-3 okupholisa ebhodini eliphansi lomgibeli wakho futhi ishise injini ibe yi-gasket yekhanda eliphefumulayo; bona Ukushisisa ngokweqile kwemoto, isitimu ngaphansi kwesivalo, nokuvikelwa kwe-gasket ekhanda. - Ungalokothi uvule ikepisi yerediyetha enomfutho oshisayo. Bheka ohlangothini olukhanyayo lwethangi lokunweba lepulasitiki elipholile ngaphansi kwesivalo. - Uhlangothi Lomgwaqo "I-Heater Core Bypass Loop" (Indlela I-Mechanic noma i-Roadside Patrol ekuvumela ngayo ukuthi Uqhubeke Ushayela Ngokuphephile): - Lapho ezimbili 16-millimeter (5/8-inch) noma 19-millimeter (3/4-inch) amapayipi okushisisa iraba adlule ngemuva kwetheku lenjini angene endaweni yokucima umlilo yekhabhinethi, uchwepheshe oseceleni komgwaqo (noma umshayeli olungisele uma injini isipholile imizuzu engu-30) angaqaqa womabili amapayipi enjoloba kumapayipi odonga lokuvikela futhi axhumanise amapayipi enjini amabili ndawonye esebenzisa $3 ithusi/iplasitiki enepayipi elihlabayo (5/8" to 5/8"), noma unqamule umkhawulo owodwa enjinini bese uxhuma ipayipi elilodwa elingaguquki elisuka esitobhini liqonde ngqo endaweni yokungena yepompo yamanzi. - Ukuvula amapayipi okushisa ngaphansi kwesivalo kuwuhlukanisa ngokuphelele umgogodla we-heater yedeshibhodi ovuzayo ukuze into epholile enguziro ingavuza ekhabetheni futhi injini ingashayelwa ngokuphepha amasonto kuze kube yilapho ideshibhodi isilungisiwe.

Kungani ingaphakathi le-windshield yami lihlala linenkungu noma libanda njalo ekuseni? (Ukuvuza Kwamanzi Afihliwe Oku-4 Okuzolungiswa Namuhla)

Ngenxa yokuthi iqhwa nenkungu ngaphakathi yemoto emile kungakheka kuphela uma amanzi awuketshezi evaleleke ndawana thize ngaphakathi kwendlu yabagibeli, hlola lezi zinkinga ezine ezifihliwe uma imoto yakho ihlale inenkungu noma iqhwa ngaphakathi:

  1. Evalekile I-Rubber A/C Evaporator Drain Tube Ngaphansi Kwemoto:
  2. Lapho i-A/C isusa umswakama kukhabhini, amanzi aconsa ngaphansi kwebhokisi le-HVAC ledeshibhodi bese ephuma ngengono encane yerabha emnyama ngemuva kahle kwesondo lomgibeli. Lapho amaqabunga, udaka, noma ulwembu lwezicabucabu luvala leyo ingono yerabha, 1 kuya ku-2 amalitha echibi lamanzi amile ngaphakathi kwebhokisi le-heater yedeshibhodi, ecwiliswa ama-foam seal futhi ephendula okokuncibilikisa iqhwa kube isihwamumazi sesitimu njalo uma ukhanyisa ukushisa. Ukusula ishubhu lokudonsa injoloba ngaphansi nge-zip-tie kukhipha ukugeleza kwamanzi avaleleke.
  3. Isihlungi Somoya Esigcwele Amanzi, Ikhabhinethi Esikhukhulayo Ngemva Kwebhokisi Leglove:
  4. Isihlungi somoya sekhabethe lephepha elingcolile, esineminyaka engu-3 ubudala ngemuva kwebhokisi legilavu simunca umswakama futhi sivimbele kufika kumaphesenti angu-60 okukhipha umoya we-defrost. Hlehlisa izingalo zokumisa i-glovebox, khipha isihlungi sekhabethe elidala, bese usifaka esikhundleni (a 3-minute job requiring zero tools on most cars).
  5. I-Windshield Cowl Evalekile noma Amashaneli E-Sunroof Drain (I-Wet Carpet Padding Ngaphansi Kwamata Aphansi):
  6. Cindezela isandla sakho siqine kukhaphethi ngaphansi komata berabha berabha bangaphambili nangemuva kanye nasebhuqwini lesondo eliyisipele kahle. Ngisho noma ukhaphethi ongaphezulu uzwakala womile, i-2-centimeter-ugqinsi lwegwebu eliwugqinsi oluwugqinsi ngaphansi kukakhaphethi* lingabamba 5 amalitha angu-10 (amalitha angu-1.3 kuya kwangu-2.6) amanzi emvula kusuka eshubhuni yokukhipha uphahla lwelanga elivalekile, umkhombe we-wiper cowl ovalekile, noma umhwamuko wepulastiki odabukile.
  7. Ungamisa Kanjani I-Sub-Zero Icing Yangaphakathi Namuhla ebusuku ("I-60-Second Cold-Air Purge" Ngaphambi Kokupaka):
  8. Kungani ingaphakathi le-windshield yakho liqina ubusuku bonke ebusika? Ngoba ufika ekhaya ikhabethe lishisiwe +22 degrees Celsius (72 degrees Fahrenheit) - Umoya ofudumele obambe iqhwa elikhulu elihwamukile kumata akho aphansi amanzi. Uma ukhiya iminyango bese ungena ngaphakathi, ingilazi ye-windshield iyehla -10 degrees Celsius, futhi wonke lowo mswakamo ofudumele obanjiwe uyajiya bese ubanda ungene ngaphakathi engilazini.
  9. I-60-Second Fix: Umzuzu owodwa ngaphambi kokufika ekhaya (noma imizuzwana engama-60 ngemva kokupaka), cisha ihitha, vula iminyango emibili noma wehlise amafasitela imizuzwana engama-60 ukuze ukhiphe umoya ofudumele, oswakeme wekhabethe bese uwufaka esikhundleni somoya obandayo, owomile wangaphandle, futhi ulahle noma iyiphi imfucumfucu yeqhwa encibilikile.

I-India ne-Asia-Pacific 112 (India); 110 / 119 & JAF (#8139) (eJapane); 995 / 999 (Singapore) Phakathi nemvula enkulu yeziphepho, abashayeli bavamise ukujikisa i-A/C ukuze ibande ngokugcwele kuyilapho beshiya umoya oqondiswe kuwindi lomoya - opholisa ingaphandle lengilazi ngaphansi kwendawo yamazolo eshisayo ngakho ukujiya kwakheka NGAPHANDLE kwe-windshield. Uma ama-wiper esula inkungu, ukujiya kuba ku-ngaphandle (phakamisa izinga lokushisa lekhabethe kancane futhi uqondise amakhaza A/C akhiphele kude engilazini).

Imibuzo evame ukubuzwa

Ngingabona kanjani uma inkungu engazelelwe kuwindshield yami ingaphakathi noma NGAPHANDLE kwengilazi phakathi nemvula eswakeme?

Gcoba izisula zakho ze-windshield ukuze ushanele kanye. Uma ama-wiper blades esula inkungu ngokuhlanzekile futhi iphinde ivele ngemva kwemizuzwana emi-2 ngokuqondile ngaphezu kwezimbobo zokuqeda isithwathwa zedeshibhodi, ukujiya kwakheka NGAPHANDLE kwengilazi ngoba isiyondisi sakho somoya sisethwe ekubeni amakhaza ashubisa umnkantsha futhi sivunguza umoya oneqhwa phansi kwewindi lomoya, kuphole ingilazi ngaphansi kwendawo efudumele, enomswakama ngaphandle. Ukumisa inkungu ngaphandle ehlobo eliswakeme noma sezulu sezulu, gcina i-A/C ivuliwe ukuze ukhiphe umswakama kukhabhini, kodwa ukhuphule izinga lokushisa kancane ukuze lifudumale/lingathathi hlangothi (22 degrees Celsius / 72 degrees Fahrenheit) futhi ushintshe ukugeleza komoya kusuka kumawindi avala isithwathwa kuya ebusweni/izimbobo zaphansi.

Kungani imoto yami A/C hlala ukhanya emakhazeni (-5C / 23F), nokho iwindshield lisagcwele inkungu ngaphandle kokuthi ngiqhekeze iwindi?

Cishe kuyo yonke imoto, ukucindezela inkinobho ethi MAX DEFROST kukhanyisa i-LED ephuzi noma eluhlaza enkinobho ye-A/C kungakhathaliseki ukuthi kubanda kangakanani ngaphandle. Kodwa-ke, i-thermistor ye-evaporator yezinga lokushisa ngaphakathi kudeshibhodi inqamula ngokuzenzakalelayo amandla ku-clutch ye-compressor ye-A/C noma nini lapho amazinga okushisa ehla ngaphansi cishe kuka-0 kuya ku-3 degrees Celsius (32 kuya ku-37 degrees Fahrenheit) ukuze ikhoyili ehwamukayo ingabi yiqhwa ibe yiqhwa eliqinile. Uma i-compressor ikhutshazwa isimo sezulu esingaphansi kweziro, imoto yakho ayinawo amandla okukhipha umswakama emoyeni - okwenza kube semqoka UKUVALA Kabusha futhi uqhekeze amawindi ezinhlangothi ezimbili avule amasentimitha angu-2 (1 iyintshi) iminithi ukuze ukhiphe umoya omswakama ngaphandle.

Ingabe ukhilimu wokushefa noma iqhinga lamazambane ligcina ingaphakathi le-windshield yemoto lingaguquguquki?

Izigqoko ezihlanzekile, ezincanyana ezicwebezelayo - njengezifutho zezimoto ezilwa nenkungu noma inani elincane lokhilimu wokushefa oyigwebu wangempela ocwebezeliswe kuwindi lomoya elingenabala - sebenza okwesikhashana ngokwehlisa ukushuba kwesimo samaconsi amanzi ajiyayo ukuze asakazeke eshidini lamanzi eliyisicaba, elisobala esikhundleni sokusabalalisa ukukhanya njengezigidi zobuhlalu obumhlophe. Kodwa-ke, uma leso singqimba se-surfactant sesigcwele umswakama, singanyakaza kakhulu ngaphansi kwezibani zangaphambili zasebusuku ezizayo, futhi ayithatheli indawo yokuhlanza ingilazi nge-isopropyl alcohol nokusebenzisa isiqeda humidifier se-A/C nge-Fresh Air ON.

Ingabe kuphephile ukuqhubeka ushayela iviki lonke nge-heater evuzayo uma nje ngigcina i-heater ivaliwe?

Cha, akuphephile ukuziba i-heater evuzayo engadluliswanga ngisho noma ucisha ifeni yedeshibhodi nezilawuli zokushisa. Ezimotweni eziningi zesimanje, isipholile senjini ecindezelwayo esishisayo sizungeza phakathi kwe-heater yedeshibhodi amaphesenti angu-100 esikhathi lapho injini isebenza khona (izinga lokushisa lilawulwa umnyango ohlanganisa umoya, hhayi i-valve yokuvala amanzi). Lokho kusho ukuthi imbobo yokuvuza kumongo we-heater ingavuleka ngokuzumayo ivuleke kakhulu ngesivinini somgwaqo omkhulu, iphampa into epholile ebilayo ezinyaweni zomgibeli futhi ikhiphe isistimu yokupholisa yenjini kuze kube yilapho ikhanda lesilinda lishisa ngokweqile futhi liguquguquka. Yiba umakhenikha afake i-under-hood heater-hose loop bypass ngaphambi kokuqhubeka nokushayela.

Kungani ingaphakathi le-windshield yami lithole ifilimu emhlophe enamafutha, ansundu nakuba imoto yami ingalahlekelwa yinoma iyiphi into epholile?

Uma ingaphakathi le-windshield yakho liba nenkani, inkungu emhlophe eguqubele emasontweni ambalwa - ikakhulukazi ngemva kokupaka elangeni elishisayo - ngaphandle kwephunga elimnandi le-antifreeze noma ukulahlekelwa okupholisayo, ubona "inkungu ye-vinyl" (i-plasticizer outgassing). Amaplastiki amakhemikhali aguquguqukayo asetshenziselwa ukugcina i-vinyl yedeshibhodi, isikhumba, kanye namapulasitiki athambile ahwamuka elangeni futhi aminyene endaweni yengilazi epholile, exutshwe nensile yomgwaqo kanye nensalela yokuphefumula/yokubhema. Ukusula ngamanzi kukodwa kugcoba lawa mafutha; qala usule ingilazi yangaphakathi ngethawula le-microfiber elimanziswe ngo-70% we-isopropyl wokuhlikihla utshwala (ukuvikela udwi ngethawula), bese uqeda ngesihlanzi sengilazi esingena-ammonia kanye nethawula elihlanzekile elomile le-waffle-weave.
