Chozizira chozizira
Chojambulira cha kutentha kozizira (DTOZH) sichophweka monga momwe chingawonekere poyamba. Anthu ambiri amaganiza kuti ali ndi udindo woyatsa / kuzimitsa chotenthetsera chozizira ndikuwonetsa kutentha koziziritsa pa bolodi. Chifukwa chake, ngati injini yasokonekera, samasamala kwambiri. Ndicho chifukwa chake ndinaganiza zolembera nkhaniyi ndikulankhula za zizindikiro zonse za kusokonezeka kwa DTOZH.
Koma choyamba, kumveketsa pang'ono. Pali masensa awiri ozizira otentha (nthawi zina 3), imodzi imatumiza chizindikiro ku muvi pa bolodi, yachiwiri (2 ojambula) kwa wolamulira. Komanso, tidzangolankhula za sensa yachiwiri, yomwe imatumiza uthenga ku kompyuta.
Ndipo kotero chizindikiro choyamba ndi chiyambi choipa cha injini yozizira. Zimangochitika kuti injini imayamba ndipo nthawi yomweyo imayima. Zambiri kapena zochepa zimagwira ntchito pa gasi. Pambuyo pakuwotha, vutoli limatha, chifukwa chiyani izi zingachitike? Sensa yoziziritsa kuzizira ikhoza kukhala ikupereka kuwerengera kolakwika kwa wowongolera. Mwachitsanzo, kuti injini kale kutentha (kutentha 90+ madigiri). Monga mukudziwa, zimatengera mafuta ambiri kuyambitsa injini yozizira kuposa yotentha. Ndipo popeza ECU "ikuganiza" kuti injini ndi yotentha, imapereka mafuta ochepa. Izi zimabweretsa chiyambi chosazizira bwino.
Chizindikiro chachiwiri ndikuyambitsa koyipa kwa injini pamoto wotentha. Apa chirichonse chiri chosiyana ndendende. DTOZH nthawi zonse imatha kupereka zowerengera mopepuka, i.e. "Uzani" wowongolera kuti injiniyo ndi yozizira. Kwa boot ozizira, izi ndi zachilendo, koma kwa otentha, ndizoipa. Injini yotentha imangodzaza ndi mafuta. Apa, mwa njira, cholakwika P0172, kusakaniza kolemera, kungawonekere. Onani ma spark plugs, ayenera kukhala akuda.
Chizindikiro chachitatu ndi kuchuluka kwa mafuta. Izi ndi zotsatira za chizindikiro chachiwiri. Ngati injini yadzaza ndi mafuta, kugwiritsa ntchito kumawonjezeka mwachibadwa.
Chachinayi ndi kuyambitsa kwachisokonezo kwa fan yoziziritsa. Galimotoyo ikuwoneka kuti ikuyenda bwino, ndi fan yokha yomwe nthawi zina imatha kuyatsa popanda chifukwa. Ichi ndi chizindikiro chachindunji cha kusagwira ntchito kwa sensa yoziziritsa kutentha. Sensor imatha kupereka mawerengedwe apakatikati. Ndiko kuti, ngati kutentha kozizira kwenikweni kwawonjezeka ndi digiri ya 1, ndiye kuti sensa imatha "kunena" kuti yawonjezeka ndi madigiri 4, kapena osayankha konse. Chifukwa chake, ngati kutentha kwa fani ndi madigiri a 101 ndipo kutentha kwenikweni ndi madigiri 97 (kuthamanga), ndiye podumpha madigiri 4, sensa "idzauza" ECU kuti kutentha kuli kale madigiri 101 ndipo ndi nthawi yoti muyatse fani. .
Choyipa kwambiri, ngati chosiyana chikachitika, sensor nthawi zina imatha kuwerengeka. N'zotheka kuti kutentha kozizira kwafika kale pa kutentha ndipo sensa "idzanena" kuti kutentha ndi kozolowereka (mwachitsanzo, madigiri 95) ndipo chifukwa chake ECU sichidzayatsa fan. Choncho, zimakupiza akhoza kuyatsa pamene galimoto yophika kale kapena osayatsa konse.
Kuyang'ana kachipangizo kozizira kozizira
Sindidzapereka matebulo omwe ali ndi mphamvu zotsutsa za masensa pa kutentha komwe kumaperekedwa, chifukwa ndimawona kuti njira yotsimikizirayi si yolondola kwenikweni. Cheke chosavuta komanso chachangu kwambiri cha DTOZH ndikungochotsa chip kuchokera pamenepo. Injini idzalowa mumayendedwe adzidzidzi, faniyo idzayatsa, kusakaniza kwamafuta kudzakonzedwa potengera kuwerengera kwa masensa ena. Ngati panthawi imodzimodziyo injini inayamba kugwira ntchito bwino, ndiye kuti sensa iyenera kusinthidwa.
Pa cheke chotsatira cha sensa yoziziritsa kutentha, mudzafunika zida zowunikira. Choyamba: muyenera kuyang'ana kutentha kwa kutentha pa injini yozizira (mwachitsanzo, m'mawa). Kuwerenga kuyenera kukhala kotentha. Chonde lolani kulakwitsa pang'ono kwa madigiri 3-4. Ndipo mutatha kuyambitsa injini, kutentha kuyenera kukwera bwino, osadumpha pakati pa kuwerenga. Ngati kutentha kunali madigiri 33, ndiyeno mwadzidzidzi anakhala madigiri 35 kapena 36, izi zikusonyeza kulephera kachipangizo.
