Kuziziritsa fan akuthamanga nthawi zonse

Mkhalidwe pamene Kuzizira kwa fan kumathamanga nthawi zonse Zitha kuchitika pazifukwa zingapo: kulephera kwa sensa yoziziritsa kuzizira kapena mawaya ake, kuwonongeka kwa fani yoyambira, kuwonongeka kwa mawaya agalimoto, "glitches" yamagetsi amagetsi a ICE (ECU) ndi ena.

kuti mumvetsetse momwe fani yoziziritsa iyenera kugwirira ntchito moyenera, muyenera kudziwa kutentha komwe kumapangidwira mugawo lowongolera kuti muyatse. Kapena yang'anani zomwe zili pa chosinthira cha fan chomwe chili mu radiator. Nthawi zambiri imakhala mkati mwa + 87 ... + 95 ° C.

M'nkhaniyi, tikambirana mwatsatanetsatane zifukwa zazikulu zonse zomwe zimakupiza kutentha kwa injini yamoto yoyaka mkati sizigwira ntchito kokha pamene kutentha kozizira kumafika madigiri 100, koma nthawi zonse ndi kuyatsa.

Zifukwa kuyatsa fani	Zoyenera kuphatikizidwa
Kulephera kwa DTOZH kapena kuwonongeka kwa waya wake	Anayambitsa injini kuyaka mkati mu mode mwadzidzidzi
Kufupikitsa mawaya pansi	Kuthamanga kwa injini yoyaka mkati, pamene kukhudzana kukuwonekera / kutha, wowotchayo akhoza kuzimitsa
Mawaya ang'onoang'ono kuti "pansi" pa DTOZH ziwiri	Kuthamanga injini yoyaka mkati (sensor yoyamba) kapena kuyatsa (sensor yachiwiri)
Fayilo yolakwika imayatsa kutumiza	Anayambitsa injini kuyaka mkati mu mode mwadzidzidzi
"Zovuta" ECU	Mitundu yosiyanasiyana, zimatengera ECU yeniyeni
Kutentha kwa radiator kumasokonekera (kuwonongeka)	Ndi injini ikuyenda, paulendo wautali
Sensor yolakwika ya freon pressure	Pamene choziziritsa mpweya chayatsidwa
Kutsika kwachangu kwa dongosolo lozizirira	Pamene injini ikuyenda

Chifukwa chiyani chowotcha chozizira chimapitilirabe kuthamanga

Ngati fani ya injini yoyaka mkati imakhala ikuyenda nthawi zonse, ndiye kuti pangakhale zifukwa 7 za izi.

Sensa yoziziritsa kutentha

• Kulephera kwa sensa yozizira kozizira kapena kuwonongeka kwa mawaya ake. Ngati chidziwitso cholakwika chimachokera ku sensa kupita ku ECU (chizindikiro chodziwikiratu kapena chocheperako, kusakhalapo kwake, dera lalifupi), ndiye kuti zolakwika zimapangidwira mu ECU, chifukwa chomwe gawo lowongolera limayika injini yoyaka mkati mwadzidzidzi. momwe zimakupiza "zimapuntha" nthawi zonse kuti pasakhale ICE wotentha. Kuti mumvetse kuti izi ndizowonongeka, zidzatheka ndi chiyambi chovuta cha injini yoyaka mkati pamene sichimatenthedwa.
• Mawaya akufupikitsa pansi. Nthawi zambiri fani imakhala ikuyenda nthawi zonse ngati itaya waya woipa. Kutengera kapangidwe ka injini yoyaka mkati, izi zitha kukhala m'malo osiyanasiyana. Ngati kapangidwe ka mota kamapereka ma DTOZH awiri, ndiye kuti "minus" ya sensa yoyamba ikasweka, fani "imatha" ndikuyatsa. Kuwonongeka kwa kutsekemera kwa mawaya a DTOZH yachiwiri, fani imathamanga nthawi zonse pamene injini yoyaka mkati ikugwira ntchito.
• Fayilo yolakwika imayatsa kutumiza. M'magalimoto ambiri, mphamvu ya fani imakhala ndi "kuphatikiza" kuchokera ku relay ndi "minus" kuchokera ku ECU potengera kutentha kwa DTOZH. "Plus" imaperekedwa nthawi zonse, ndi "minus" pamene kutentha kwa ntchito ya antifreeze kumafika.
• "Glitches" yamagetsi control unit. Momwemonso, ntchito yolakwika ya ECU ikhoza kuyambitsidwa ndi vuto la pulogalamu yake (mwachitsanzo, pambuyo powunikira) kapena ngati chinyezi chimalowa mkati mwake. Monga chinyezi, pakhoza kukhala banal antifreeze yomwe idalowa mu ECU (yogwirizana ndi magalimoto a Chevrolet Cruze, pamene antifreeze imalowa mu ECU kudzera mu chubu chotenthetsera chamoto, ili pafupi ndi ECU).
• Radieta yakuda. Izi zimagwiranso ntchito ku radiator yayikulu komanso radiator ya air conditioner. Pachifukwa ichi, nthawi zambiri zimakupiza zimathamanga nthawi zonse pamene air conditioner ili.
• Freon pressure sensor mu air conditioner. Ikalephera ndipo pali kutayikira kwa firiji, dongosololi "likuwona" kuti radiator ikuwotcha kwambiri ndikuyesa kuziziritsa ndi fan nthawi zonse. Kwa oyendetsa galimoto ena, choyatsira mpweya chikatsegulidwa, fani yozizirira imayenda nthawi zonse. M'malo mwake, izi siziyenera kukhala choncho, chifukwa izi zikuwonetsa radiator yotsekeka (yonyansa), kapena mavuto ndi sensor yamphamvu ya Freon (Freon leak).
• Kutsika kwachangu kwa dongosolo lozizirira. Kuwonongeka kumatha kulumikizidwa ndi mulingo wocheperako wozizirira, kutayikira kwake, chotenthetsera cholakwika, kulephera kwa pampu, kupsinjika kwa kapu ya radiator kapena thanki yokulitsa. Ndi vuto loterolo, faniyo sangagwire ntchito nthawi zonse, koma kwa nthawi yayitali kapena kuyatsa pafupipafupi.

Zoyenera kuchita ngati fan yoziziritsa ikugwira ntchito nthawi zonse

Pamene injini yoyaka moto yamkati ikuzizira nthawi zonse, ndikofunikira kuyang'ana kuwonongeka pochita njira zingapo zosavuta zowunikira. Chekecho chiyenera kuchitidwa motsatizana, kutengera zomwe zingayambitse.

Kuyeretsa radiator

• Onani zolakwika mu kukumbukira kwa ECU. Mwachitsanzo, khodi yolakwika p2185 imasonyeza kuti palibe "minus" pa DTOZH, ndipo ena angapo (kuyambira p0115 mpaka p0119) amasonyeza zovuta zina pamagetsi ake.
• Onani kukhulupirika kwa mawaya. Kutengera kapangidwe ka injini, mawaya omwe amalumikizidwa ndi fan drive amatha kuonongeka (nthawi zambiri kutchinjiriza kumasokonekera), zomwe zimapangitsa kuti pakhale kufupi. Choncho, mumangofunika kupeza malo omwe waya wawonongeka. Izi zitha kuchitika mowoneka kapena ndi ma multimeter. Monga njira, ikani singano ziwiri pazolumikizana ndi chip ndikutseka pamodzi. Ngati mawaya ali osasunthika, ECU ipereka cholakwika chamoto.
• Onani DTOZH. Chilichonse chikakhala mu dongosolo ndi mawaya ndi magetsi a sensa, ndiye kuti ndi bwino kuyang'ana kutentha kozizira. Pamodzi ndikuyang'ana kachipangizo komweko, muyeneranso kuyang'ana zolumikizira pa chip yake ndi mtundu wa chip fixation (ngati eyelet / latch yasweka). Ngati ndi kotheka, yeretsani zolumikizana ndi chip kuchokera ku oxides.
• Relay ndi fuse kufufuza. Onani ngati mphamvu imachokera ku relay kupita ku fan pogwiritsa ntchito multimeter (mutha kupeza nambala ya pini pazithunzi). Pali nthawi zina pamene "imamatira", ndiye muyenera kusintha. Ngati palibe mphamvu, yang'anani fuyusi.
• Kuyeretsa ma radiator ndi makina ozizira. Ngati radiator yapansi kapena radiator ya air conditioner yakutidwa ndi zinyalala, iyenera kutsukidwa. Kutsekeka kwa radiator ya injini yoyaka mkati kumatha kupanga mkati, ndiye muyenera kuyeretsa dongosolo lonse lozizirira ndi njira zapadera. Kapena chotsani radiator ndikutsuka payokha.
• Yang'anani momwe makina ozizira amagwirira ntchito. Faniyi imatha kugwira ntchito mosalekeza ndi magwiridwe antchito ozizirira komanso zinthu zake. Choncho, m'pofunika kuyang'ana dongosolo lozizira, ndipo ngati zowonongeka zizindikirika, konzekerani kapena kusintha magawo ake.
• Kuyang'ana mulingo wa freon ndi magwiridwe antchito a refrigerant pressure sensor. Kuti muchite izi ndikuchotsa zomwe zimayambitsa, ndi bwino kupita ku msonkhano.
• Mtengo wa ECU ndi njira yomaliza pamene ma node ena onse afufuzidwa kale. Nthawi zambiri, gawo lowongolera liyenera kuthetsedwa ndikuphwanyidwa nyumba yake. ndiye fufuzani mkhalidwe wa bolodi lamkati ndi zinthu zake, ngati kuli kofunikira, yeretsani ndi mowa kuchokera ku antifreeze ndi zinyalala.

M'chilimwe, kuyendetsa galimoto ndi fani nthawi zonse sikoyenera, koma kovomerezeka. Komabe, ngati faniyo imatembenuka nthawi zonse m'nyengo yozizira, tikulimbikitsidwa kuti tipeze ndi kukonza zowonongeka mwamsanga.

Pomaliza

Nthawi zambiri, zimakupiza kuzirala kwa rediyeta kumatembenuka nthawi zonse chifukwa chafupikitsa pagawo loyambira kapena ma waya ake. Mavuto ena sachitika kawirikawiri. Choncho, diagnostics ayenera kuyamba ndi kuyang'ana relay, mawaya ndi kukhalapo kwa zolakwika kukumbukira kompyuta.
