Inzwa yokushisa kwemoto iLada Granta

Imininingwane enjalo ebonakala ingabalulekile yemoto njengenzwa yokushisa yeLada Grant ingenye yamadivayisi abaluleke kakhulu emotweni. Ukusebenza okuphephile kwenjini evuthayo yangaphakathi (ICE) kuncike ekusebenzeni kwayo. Ukukhonjwa okufika ngesikhathi kwembangela yokwanda okubukhali kwezinga lokushisa kwe-coolant kuzosindisa umnikazi wemoto ezinkingeni zomgwaqo kanye nezindleko ezinkulu ezingalindelekile.

Lada Granda:

Kungani ipholisa libila

Kwesinye isikhathi ungathola imoto imi eceleni komgwaqo i-hood ibheke phezulu, ngaphansi kwayo kuphuma isitimu ngamakilabhu. Lona umphumela wokuhluleka kwenzwa yokushisa ye-Lada Grant. Umshini unikeze ulwazi olungalungile ku-electronic control unit (ECU), futhi uhlelo lokungenisa umoya alukwazanga ukusebenza ngesikhathi, okubangele ukuthi i-antifreeze ibile.

Ngenzwa yezinga lokushisa elipholile engalungile (i-DTOZH) ku-Lada Granta, i-antifreeze ingase ibile ngenxa yezizathu ezimbalwa:

1. Ibhande lesikhathi liyaxega.
2. Ukuhluleka kokuthwala iphampu.
3. Ukuhluleka kwe-thermostat.
4. Ukuvuza kwe-antifreeze.

Ibhande lesikhathi elixegayo

Ibhande lingaxega ngenxa yokuphelelwa yimpilo noma ukungasebenzi kahle. Ibhande liqala ukushelela phezu kwamazinyo egiya lokushayela iphampu. Ijubane lokuhamba kwe-antifreeze ku-radiator liyehla, futhi izinga lokushisa likhuphuka kakhulu. Ibhande liqiniswa noma lifakwe umkhiqizo omusha.

Ibhande lesikhathi:

Ukuhluleka kokuthwala iphampu

Umphumela wokuhluleka kwama-bearings wepompo yamanzi (okupholisa) ukuthi iphampu iqala ukugoba. I-antifreeze iyayeka ukuhamba ngaphakathi kwesekethe enkulu yesistimu yokupholisa ye-Grant, futhi uketshezi, ukushisisa ngokushesha, lufike endaweni yokubilisa engu-100 ° C. Iphampu ihlakazwa ngokushesha futhi kufakwe iphampu entsha.

Iphampu yamanzi:

Ukuhluleka kwe-thermostat

Ngokuhamba kwesikhathi, idivayisi ingase iqede insiza yayo, futhi lapho i-antifreeze ishisa, i-valve iyayeka ukusebenza. Ngenxa yalokho, i-antifreeze ayikwazi ukujikeleza ngesifunda esikhulu futhi idlule kurediyetha. Uketshezi olusele ejazini lenjini luyashisa ngokushesha futhi lubile. I-thermostat idinga ukushintshwa ngokushesha.

I-Thermostat:

ukuvuza kwe-antifreeze

Lokhu kungenzeka ngenxa yokuvuza ekuxhumekeni kwamapayipi esistimu yokupholisa, ukulimala kwe-radiator, ithangi lokunweba kanye nepompo. Izinga eliphansi le-antifreeze lingabonakala emakakweni ethangini lokunweba. Kuzobonakala futhi ngokuthi inaliti ihamba ngokushesha kangakanani noma amanani okushisa ashintsha kusixhumi esibonakalayo sephaneli yezinsimbi. Udinga ukwengeza uketshezi ezingeni oyifunayo bese uya egalaji noma esiteshini sesevisi.

Ithangi lokunweba:

Ukuqokwa

Inqubo yokuthungela ingxube kaphethiloli kumasilinda enjini yomlilo yangaphakathi ihambisana nokwanda kwezinga lokushisa elifinyelela ku-20000C. Uma ungagcini izinga lokushisa lokusebenza, i-cylinder block enayo yonke imininingwane izovele iwe. Inhloso yesistimu yokupholisa injini iwukugcina amandla okushisa enjini ezingeni eliphephile.

Inzwa yezinga lokushisa lenjini kaGrant iyinzwa etshela i-ECU ukuthi into epholile ishisa kangakanani. Iyunithi ye-elekthronikhi yona, ehlaziya idatha evela kuzo zonke izinzwa, okuhlanganisa i-DTOZH, iletha zonke izinhlelo zenjini evuthayo yangaphakathi kumodi yokusebenza efanele nebhalansile.

I-MOT:

Idivayisi nenqubo yokusebenza

Inzwa yezinga lokushisa ye-Grant iyi-thermistor yokumelana ne-variable. I-thermocouple, evalwe ngekesi lethusi eline-threaded tip, inciphisa ukumelana kwesekethe kagesi uma ishiswa. Lokhu kuvumela i-ECU ukuthi inqume izinga lokushisa elipholile.

Idivayisi ye-MOT:

Uma sicabangela inzwa engxenyeni, singabona amacembe amabili okuxhumana atholakala phezulu nangaphansi kwe-thermistor, eyenziwe nge-alloy yensimbi ekhethekile, eshintsha ukumelana kwayo kuye ngezinga lokushisa. Vala bobabili abathintwayo. Umuntu uthola amandla kunethiwekhi esebhodini. I-current, isidlule ku-resistor enesici esishintshile, iphuma ngothintana naye wesibili bese ingena ku-microprocessor yekhompyutha ngocingo.

Amapharamitha alandelayo enjini evuthayo yangaphakathi ancike ku-DTOZH:

• ukufundwa kwezinzwa zokushisa kuphaneli yensimbi;
• ukuqala okufika ngesikhathi kwe-fan yokupholisa ephoqelekile yenjini yangaphakathi yomlilo;
• ukucebisa ingxube kaphethiloli;
• isivinini injini engenzi lutho.

Izimpawu zokungasebenzi kahle

Zonke izenzakalo ezimbi ezivelayo, ngokushesha nje lapho i-DTOZH ihluleka, zingachazwa kanje:

• ukusetshenziswa kukaphethiloli kwanda kakhulu;
• kunzima ukuqala "okubandayo" kwenjini ";
• lapho uqala, i-muffler "iphefumula";
• i-radiator fan isebenza njalo;
• isiphephetha-moya asivuli ezingeni elibucayi lezinga lokushisa elipholile.

Ngaphambi kokuthatha i-disassembly yemitha, ochwepheshe batusa ukuthi uqale uhlole ukuthembeka kwe-wiring kanye nokuqiniswa kwezixhumi.

Uphi

Ukuthola inzwa yokushisa akunzima neze. Abathuthukisi be-VAZ-1290 Lada Granta 91 bakha inzwa ku-thermostat izindlu. Lena indawo nje kusistimu yokupholisa lapho ungasetha khona izinga eliphezulu lokushisisa kwe-antifreeze. Uma uphakamisa i-hood, ungabona ngokushesha lapho i-thermostat itholakala khona. Itholakala ngakwesokudla kwekhanda lesilinda. Sithola inzwa esihlalweni somzimba we-valve eshisayo.

Indawo ye-DTOZH (inadi eliphuzi liyabonakala):

Ukuhlolwa kokusebenza

Ukuze uhlole ukusebenza komshayeli, udinga ukuyisusa (indlela yokwenza lokhu, bheka ngezansi) bese ulungiselela okulandelayo:

• hlanza inzwa othulini nasekungcoleni;
• i-multimeter yedijithali;
• i-thermocouple enenzwa noma i-thermometer;
• isitsha esivulekile samanzi abilayo.

I-Multimeter:

Ihlola inqubo

Ukuhlola i-DTOZH kwenziwa kanje.

1. Izitsha ezinamanzi zibekwe esitofini bese zivula isishisi segesi noma isitofu sikagesi.
2. I-multimeter isethwe kumodi ye-voltmeter. I-probe ivala othintana naye ngo-"0" wekhawunta. Inzwa yesibili ixhunywe kokunye okukhiphayo kwenzwa.
3. Isilawuli sehliselwa endishini ukuze ithiphu laso kuphela lihlale emanzini.
4. Enqubweni yokushisisa amanzi, izinguquko zokushisa kanye namanani okumelana nezinzwa ayarekhodwa.

Idatha etholiwe iqhathaniswa nezinkomba zethebula elilandelayo:

Izinga lokushisa lamanzi ethangini, °C	Ukumelana nezinzwa, kOhm

Isixhumi esibonakalayo sohlelo lweselula lwe-Opendiag ku-Android:

Ukufaka esikhundleni

Uma unamakhono okuphatha amathuluzi alula, ukufaka esikhundleni sedivayisi eyonakele ngenzwa entsha akunzima. Ngaphambi kokuqala umsebenzi, kufanele uqiniseke ukuthi injini iyabanda, imoto imi endaweni eyisicaba kubhuleki lesandla futhi kukhishwe itheminali enegethivu ebhethrini. Ngemva kwalokho, qhubeka kanje:

1. I-chip yokuxhumana enentambo iyakhishwa ekhanda lesixhumi se-DTOZH.
2. Khipha enye (cishe i-½ ilitha) yesipholile esitsheni esifanele ngokukhipha ibhawudi ngaphansi kwebhulokhi yesilinda.
3. I-wrench evulekile ku-"19" ikhulula inzwa endala.
4. Faka inzwa entsha bese ufaka i-chip yokuxhumana kusixhumi se-DTOZH.
5. I-Antifreeze yengezwa ethangini lokunweba lifike ezingeni olifunayo.
6. Itheminali ibuyiselwa endaweni yayo ebhethrini.

Ngekhono elithile, akudingekile ukukhipha i-coolant. Uma ucindezela ngokushesha umgodi ngomunwe wakho, bese ufaka ngokushesha futhi uphendule umshayeli omusha 1-2, khona-ke ukulahlekelwa kwe-antifreeze kuyoba amaconsi ambalwa. Lokhu kuzokusindisa ekusebenzeni "okunzima" kokukhipha amanzi bese wengeza i-antifreeze.

Isiqinisekiso ngokumelene nezinkinga esikhathini esizayo sizoba isixwayiso lapho ukhetha inzwa entsha yezinga lokushisa elipholile. Kufanele uthenge amadivayisi kuphela kubakhiqizi abanophawu oluthembekile. Uma imoto ineminyaka engaphezu kwengu-2 ubudala noma i-mileage isivele iyizinkulungwane ezingu-20 km, khona-ke i-DTOZH eyisipele esiqwini seLada Grant ngeke ibe yinto engafaneleki.
