Inzwa yokushisa komoya yokungenisa
Okuqukethwe
I-DTVV ejwayelekile
Inzwa yokushisa komoya yokungenisa ingenye yezinhlelo eziningi nezinzwa emotweni. ukuwohloka ekusebenzeni kwayo kungathinta ngqo ukusebenza kwenjini yomlilo yangaphakathi, ikakhulukazi ngenkathi ebandayo.
Iyini inzwa yomoya ongenayo futhi itholakala kuphi
Inzwa yokushisa komoya yokungenisa (isifinyezo se-DTVV, noma i-IAT ngesiNgisi) okudingekayo ukulungisa ukwakheka kwengxube kaphethiloliinikezwa injini evuthayo yangaphakathi. Lokhu kuyadingeka ekusebenzeni okujwayelekile kwemoto ezimweni ezihlukene zokushisa. Ngokufanelekile, iphutha kunzwa yokushisa komoya oyithathayo kuya kokuningi lisongela ukusetshenziswa kukaphethiloli ngokweqile noma ukusebenza okungazinzile kwenjini evuthayo yangaphakathi.
I-DTVV itholakala endaweni yokuhlunga umoya noma ngemuva kwayo. Kuncike ekuklanyweni kwemoto. Yena kwenziwa ngokwehlukana noma ingase ibe yingxenye yenzwa yokugeleza komoya (DMRV).
Itholakala kuphi inzwa yokushisa komoya oyithathayo?
ukwehluleka kwenzwa yokushisa komoya
Kunezibonakaliso ezimbalwa zenzwa yokushisa komoya yokungenisa engasebenzi kahle. Phakathi kwazo:
- ukuphazamiseka ekusebenzeni kwenjini yomlilo yangaphakathi ngokungenzi lutho (ikakhulukazi ngenkathi ebandayo);
- isivinini esiphezulu kakhulu noma esiphansi sokungenzi lutho senjini evuthayo yangaphakathi;
- izinkinga ngokuqala injini yomlilo yangaphakathi (esithwathwaneni esinzima);
- ukunciphisa amandla e-ICE;
- ukugcwala kwamafutha.
Ukuhlukana kungaba ngenxa yezizathu ezilandelayo:
- ukulimala komshini kunzwa okubangelwa izinhlayiya eziqinile;
- ukulahlekelwa ukuzwela ngenxa yokungcola (ukwanda kwe-inertia yesikhashana);
- I-voltage enganele ohlelweni lukagesi lwemoto noma ukuthintana kahle kukagesi;
- ukwehluleka kwe-wiring yesignali yenzwa noma ukusebenza kwayo okungalungile;
- isifunda esifushane ngaphakathi kwe-IAT;
- ukungcoliswa koxhumana nabo benzwa.
Ukuhlola nokuhlanza i-DTVV.
Ihlola inzwa yokushisa komoya oyithathayo
Ngaphambi kokuba uhlole inzwa yokushisa komoya wokungena, udinga ukuqonda isimiso sokusebenza kwayo. Inzwa isuselwe ku-thermistor. Kuye ngezinga lokushisa lomoya ongenayo, i-DTVV ishintsha ukumelana kwayo nogesi. Izimpawu ezikhiqizwa kuleli cala zithunyelwa ku-ECM ukuze kutholwe isilinganiso esifanele sengxube kaphethiloli.
Ukuxilongwa kwenzwa yokushisa komoya wokungena kufanele kwenziwe ngesisekelo sokulinganisa ukumelana nobukhulu bezimpawu zikagesi eziphuma kuyo.
Ukuhlolwa kuqala ngokubalwa kokumelana. Ukuze wenze lokhu, sebenzisa i-ohmmeter ngokukhipha inzwa emotweni.Inqubo yenzeka ngokunqamula izintambo ezimbili bese uzixhuma kudivayisi yokulinganisa (multimeter). Isilinganiso siyenziwa ezindleleni ezimbili zokusebenza kwenjini yangaphakathi evuthayo — “kubanda” nangesivinini esigcwele.
Ukunikezwa kwesilinganiso se-voltage
Isilinganiso sokumelana nezinzwa
Esimweni sokuqala, ukumelana kuyoba ukumelana okuphezulu (ama-kOhm amaningana). Kwesibili - ukumelana okuphansi (kufika ku-kOhm eyodwa). Imiyalo yokusebenza yenzwa kufanele ibe netafula noma igrafu enamanani okumelana nokuya ngezinga lokushisa. Ukuchezuka okukhulu kubonisa ukusebenza okungalungile kwedivayisi.
Ngokwesibonelo, sinikeza itafula isilinganiso lokushisa kanye ukumelana inzwa yokungenisa umoya injini ovuthayo yangaphakathi VAZ 2170 "Lada Priora" imoto:
| Izinga lokushisa lomoya, °C | Ukumelana, kOhm |
| -40 | 39,2 |
| -30 | 23 |
| -20 | 13,9 |
| -10 | 8,6 |
| 0 | 5,5 |
| + 10 | 3,6 |
| + 20 | 2,4 |
| + 30 | 1,7 |
| + 40 | 1,2 |
| + 50 | 0,84 |
| + 60 | 0,6 |
| + 70 | 0,45 |
| + 80 | 0,34 |
| + 90 | 0,26 |
| + 100 | 0,2 |
| + 110 | 0,16 |
| + 120 | 0,13 |
Esigabeni esilandelayo, hlola ukuxhumeka kwama-conductor kudivayisi yokulawula. Okusho ukuthi, usebenzisa umhloli, qiniseka ukuthi kukhona conductivity yokuxhumana ngamunye phansi. Sebenzisa i-ohmmeter, exhunywe phakathi kwesixhumi senzwa yezinga lokushisa nesixhumi sedivayisi yokulawula enqanyuliwe. Kulokhu, inani kufanele libe ngu-0 ohm (qaphela ukuthi udinga i-pinout kulokhu). Hlola noma yikuphi othintana naye kusixhumi senzwa nge-ohmmeter nesixhumi esinqanyuliwe emhlabathini.
Isilinganiso sokumelana ne-DTVV seToyota Camry XV20
Isibonelo, ukuze uhlole ukumelana kwenzwa kuToyota Camry XV20 ngenjini engu-6-cylinder, udinga ukuxhuma i-ohmmeter (multimeter) ekuphumeni kwenzwa yesi-4 neyesi-5 (bheka umfanekiso).
Nokho, ngokuvamile i-DTVV inemiphumela emibili ye-thermistor, lapho kudingekile ukuhlola ukumelana kwesici. sikulethela futhi umdwebo wokuxhumeka kwe-IAT emotweni ye-Hyundai Matrix:
Umdwebo wokuxhuma we-DTVV ne-DBP ye-Hyundai Matrix
Isigaba sokugcina sokuqinisekisa sithi thola i-voltage kusixhumi. Kulokhu, udinga ukuvula ukuthungela imoto. Inani lesiginali kagesi kufanele libe ngu-5 V (kwamanye amamodeli e-DTVV, leli nani lingahluka, lihlole kudatha yepasipoti).
Inzwa yokushisa komoya oyithathayo iyidivayisi ye-semiconductor. Ngenxa yalokho, ayikwazi ukumiswa. Kungenzeka kuphela ukuhlanza othintana nabo, hlola izintambo zesignali, kanye nokushintsha ngokuphelele idivayisi.
Ukulungiswa kwenzwa yezinga lokushisa lomoya
Ngingayilungisa kanjani inzwa yezinga lokushisa engu-BB.
The kakhulu uhlobo olulula lokulungisa i-IAT - ukuhlanza. Ukuze wenze lokhu, uzodinga uhlobo oluthile loketshezi lokuhlanza (isicoci se-carb, utshwala, noma esinye isihlanzi). Nokho, khumbula ukuthi udinga ukusebenza ngokucophelela, ukuze ungalimazi abathintwayo bangaphandle.
Uma uhlangabezana nenkinga lapho inzwa ibonisa izinga lokushisa elingalungile, esikhundleni sokushintshwa okuphelele, ungayilungisa. Kwalokhu thenga i-thermistor enezici ezifanayo noma ezifanayoene-thermistor esivele ifakiwe emotweni.
Ingqikithi yokulungisa i-soldering futhi iwashintsha endaweni yezindlu zezinzwa. Ukuze wenze lokhu, uzodinga insimbi ye-soldering kanye namakhono afanele. Inzuzo yalokhu kulungiswa ukonga imali ebalulekile, njengoba i-thermistor ibiza cishe idola noma ngaphansi.
Ukushintsha inzwa yokushisa komoya oyithathayo
Inqubo yokufaka esikhundleni ayinzima futhi ayithathi isikhathi esiningi. Inzwa ifakwe kuma-bolts angu-1-4 adinga ukukhishwa, kanye nokunyakaza okulula ukunqamula isixhumi samandla ukuze kukhishwe inzwa yomoya wokungenisa endaweni yayo.
Uma uthenga inzwa entsha, qiniseka ukuthi iyifanele imoto yakho. Intengo yayo isuka ku-$30 iye ku-$60, kuya ngohlobo lwemoto nomkhiqizi.
