Kutentha koyipa koyambira

Kubwera kwa masiku otentha, madalaivala ochulukirachulukira akukumana ndi vuto la kusayambira bwino kwa injini yoyaka mkati pamoto wotentha pambuyo pa mphindi zingapo zoyimitsa. Komanso, ili siliri vuto ndi carburetor ICEs - momwe zinthu zilili ngati sizikuyambira pakutentha zimatha kudikirira eni ake onse amagalimoto okhala ndi jakisoni wa ICE ndi magalimoto adizilo. Kungoti zifukwa za aliyense ndizosiyana. Apa tiyesetsa kuwasonkhanitsa ndikuzindikira omwe amapezeka kwambiri.

Pamene si kuyamba pa otentha carburetor mkati kuyaka injini

Chifukwa chiyani zimayambira moyipa pa yotentha komanso zomwe zimatulutsa

Zifukwa zomwe carburetor samayambira bwino pamoto wotentha ndizomveka bwino, apa makamaka Kusakhazikika kwa petulo ndiko chifukwa chake. Mfundo yaikulu ndi yakuti injini yoyaka mkati ikatenthedwa mpaka kutentha kwa ntchito, carburetor imatenthetsanso, ndipo itatha kuzimitsa, mkati mwa mphindi 10-15, mafuta amayamba kusungunuka, choncho zimakhala zovuta kuyambitsa galimoto.

Kuyika kwa textolite spacer kungathandize pano, koma sikumapereka zotsatira za 100%.

Kuti muyambitse injini yoyaka moto yamkati muzochitika zotere, kukanikiza chopondapo cha gasi pansi ndikutsuka makina amafuta kumathandizira, koma osapitilira masekondi 10-15, chifukwa mafuta amatha kusefukira makandulo. Ngati funso likukhudza Zhiguli, ndiye kuti pampu yamafuta ingakhalenso yolakwa, popeza mapampu amafuta a Zhiguli sakonda kutentha ndipo nthawi zina amakana kwathunthu kugwira ntchito akatenthedwa.

Pamene injini ya jekeseni sikuyamba

Popeza jekeseni ICE ndizovuta kwambiri kuposa carburetor, motero, padzakhala zifukwa zambiri zomwe injini yotereyi siimayambira. ndiye, iwo akhoza kukhala kulephera kwa zigawo zotsatirazi ndi njira:

1. Sensa yoziziritsa kutentha (OZH). M'nyengo yotentha, imatha kulephera ndikupereka chidziwitso cholakwika pakompyuta, kutanthauza kuti kutentha kozizira kumakhala kopitilira muyeso.
2. Crankshaft position sensor (DPKV). Kulephera kwake kudzatsogolera ku ntchito yolakwika ya ECU, yomwe sichidzalola kuti injini yoyaka moto iyambe.
3. Mass air flow sensor (DMRV). M'nyengo yotentha, sensayo singathe kulimbana ndi ntchito zomwe wapatsidwa, chifukwa kusiyana kwa kutentha pakati pa mpweya wobwera ndi wotuluka kudzakhala kochepa. Kuphatikiza apo, nthawi zonse pali kuthekera kwa kulephera kwake pang'ono kapena kwathunthu.
4. jekeseni mafuta. Apa zinthu ndi zofanana ndi carburetor ICE. Kagawo kakang'ono ka mafuta kamene kamasanduka nthunzi pa kutentha kwakukulu, kupanga mafuta osakaniza osakaniza. Choncho, injini kuyaka mkati sangathe kuyamba bwinobwino.
5. Pampu yamafuta. ndicho, muyenera kuyang'ana ntchito yake valavu cheke.
6. Idle Speed ​​​​Regulator (IAC).
7. Wowongolera kuthamanga kwamafuta.
8. moto module.

ndiye tiyeni tipitilize kuganizira zomwe zingayambitse kusayamba kotentha kwamagalimoto okhala ndi dizilo ICE.

Pamene kuli kovuta kuyamba pa injini yotentha ya dizilo

Tsoka ilo, injini za dizilo nthawi zina zimatha kulephera kuyambitsa kukatentha. Nthawi zambiri, zomwe zimayambitsa izi ndi kuwonongeka kwa mfundo zotsatirazi:

1. Sensor yoziziritsa. Pano zinthu zikufanana ndi zomwe tafotokoza m’chigawo chapitachi. Sensa ikhoza kulephera ndipo, motero, kufalitsa uthenga wolakwika ku kompyuta.
2. crankshaft position sensor. Zinthu zikufanana ndi injini ya jakisoni.
3. Sensor yotulutsa mpweya wambiri. Momwemonso.
4. Pampu yamafuta othamanga kwambiri. Izi zitha kuchitika chifukwa chakuwonongeka kwakukulu kwa ma bushings ndi chisindikizo chamafuta a pampu drive shaft. Mpweya umalowa mu mpope kuchokera pansi pa bokosi loyika zinthu, zomwe zimapangitsa kuti zikhale zosatheka kulimbikitsa kugwira ntchito mu chipinda cha sub-plunger.
5. Injini ya dizilo idle system.
6. Wowongolera kuthamanga kwamafuta.
7. moto module.

Tsopano tiyesa kufotokoza mwachidule zomwe zaperekedwa kuti zikhale zosavuta kuti mupeze chifukwa cha kuwonongeka ngati chinachitika pa galimoto yanu.

Zifukwa XNUMX Zapamwamba Zoyambira Zoyipa Kwambiri

Choncho, malinga ndi ziwerengero, zifukwa zazikulu za kusayamba bwino kwa injini kuyaka mkati pambuyo downtime pa kutentha kwambiri ndi:

1. Mafuta osakaniza osakaniza, omwe amapangidwa chifukwa cha mafuta otsika kwambiri (tizigawo tating'ono tating'ono tating'ono timasanduka nthunzi, ndipo mtundu wa "mafuta a chifunga" umapezeka).
2. Sensor yoziziritsa yolakwika. Pa kutentha kozungulira, pali kuthekera kwa ntchito yake yolakwika.
3. Kuyatsa kolakwika. Ikhoza kukhazikitsidwa molakwika kapena pangakhale zovuta ndi choyatsa choyatsira.

tidzakupatsaninso tebulo lomwe tidayesa kuwonetsa ma node omwe angayambitse mavuto, ndi zomwe ziyenera kufufuzidwa mumitundu yosiyanasiyana ya ICE.

Chifukwa chiyani injini yotentha imayima

Eni magalimoto ena amakumana ndi vuto lomwe injini yomwe ikuyenda kale komanso yotenthetsera mwadzidzidzi imayimilira. Kuphatikiza apo, izi zimachitika sensor ikakhazikitsa kutentha kwanthawi zonse. Pakhoza kukhala zifukwa zingapo za izi. ndiye tidzawalingalira mwatsatanetsatane, ndikuwonetsanso zomwe ziyenera kuchitidwa pazochitika zinazake.

1. Mafuta otsika kwambiri. Izi ndizochitika, mwachitsanzo, ngati mutayendetsa galimoto kuchoka ku gasi, ndipo patapita nthawi yochepa, injini yoyaka mkati imayamba "kutsokomola", galimotoyo imagwedezeka ndi kugulitsa. Yankho lake apa ndi lodziwikiratu - kukhetsa mafuta otsika kwambiri, yeretsani makina amafuta ndikusintha fyuluta yamafuta. m'pofunikanso m'malo makandulo, koma ngati ali atsopano, inu mukhoza kudutsa ndi kuwayeretsa iwo. Mwachibadwa, sikuli koyenera kuyimitsidwa ndi malo oterowo m'tsogolomu, ndipo ngati mwasunga risiti, mukhoza kupita kumeneko ndikukanena za ubwino wa mafuta.
2. Fyuluta yamafuta. Ndi kuyimitsidwa kwa injini, muyenera kuyang'ananso momwe fyuluta yamafuta ilili. Ndipo ngati, malinga ndi malamulo, ndikofunika kale kuti musinthe, ndiye kuti muyenera kuchita, mosasamala kanthu kuti ndizotsekedwa kapena ayi.
3. Fyuluta yamlengalenga. Pano zinthu zilinso chimodzimodzi. Injini yoyatsira yamkati imatha "kutsamwitsa" pazosakaniza zokometsedwa ndikuyima patangopita nthawi yochepa. Yang'anani momwe zilili ndikusintha ngati kuli kofunikira. Mwa njira, motere mutha kuchepetsanso kugwiritsa ntchito mafuta.
4. Mpope mafuta. Ngati sichigwira ntchito mokwanira, ndiye kuti injini yoyaka mkati idzalandira mafuta ochepa, ndipo, motero, idzayima pakapita nthawi.
5. Jenereta. Ngati idalephera kwathunthu kapena pang'ono, ndiye kuti idasiya kulipiritsa batire. Dalaivala sangazindikire nthawi yomweyo, yambani injini yoyaka mkati ndikupita. Komabe, idzangoyenda mpaka batire itatulutsidwa. Tsoka ilo, sikudzakhalanso kotheka kuyambitsanso injini yoyaka mkati mwake. Nthawi zina, mutha kuyesa kulimbitsa lamba wa alternator. Ngati izi sizinathandize, muyenera kuyimbira galimoto yokokera kapena kuyimbira anzanu kuti mukokere galimoto yanu kupita ku garaja kapena kothandizira.

Yesani kuwunika momwe zinthu zilili pamwambazi ndi njira. Ngakhale zowonongeka zing'onozing'ono, ngati sizinakhazikitsidwe m'nthawi yake, zimatha kukhala zovuta zazikulu zomwe zingasinthe kukhala zodula komanso zovuta kukonza kwa inu.

Pomaliza

Choyambirira chomwe muyenera kuchita kuti injini yoyaka mkati iyambike nthawi zonse pakuwotcha ndikuwonjezera mafuta pamagalasi otsimikiziridwa, komanso kuwunika momwe galimoto yanu ilili. Ngati, ngakhale patangotha ​​​​nthawi yochepa pakutentha, injini yoyatsira mkati siyamba, ndiye tsegulani kaye kaye (kanikizani chowongolera) kapena chotsani chivundikiro cha fyuluta ndikuchisiya chitseguke kwa mphindi zingapo. Panthawi imeneyi, mafuta amadzimadzi amasungunuka ndipo mudzatha kuyambitsa injini yoyaka mkati mwachizolowezi. Ngati ndondomekoyi sinathandize, ndiye kuti muyenera kuthetsa mavuto pakati pa mfundo ndi njira zomwe tafotokozazi.
