Ubushyuhe bwa sensor: kugenzura ubushyuhe bwa moteri

datchik_ubushyuhe_1

Imodoka yose ifite sensor yoroheje ariko yingenzi ifasha gukurikirana imikorere ya moteri - icyuma gikonjesha.Soma ibyerekeranye nubushyuhe bwubushyuhe icyo aricyo, igishushanyo gifite, kumahame umurimo wacyo ushingiyeho, nu mwanya ufata mumodoka.

 

Niki cyerekana ubushyuhe

Ubushyuhe bwa Coolant (DTOZh) ni sensor ya elegitoronike yagenewe gupima ubushyuhe bwa coolant (coolant) ya sisitemu yo gukonjesha ya moteri yaka imbere.Amakuru yabonetse na sensor akoreshwa mugukemura ibibazo byinshi:

• Kugenzura amashusho yubushyuhe bwumuriro w'amashanyarazi - amakuru ava muri sensor yerekanwa ku gikoresho gikwiranye (thermometero) ku kibaho kiri mu modoka;
• Guhindura imikorere ya sisitemu zitandukanye za moteri (ingufu, gutwika, gukonjesha, gaze ya gaze ya gaze nizindi) ukurikije uko ubushyuhe buriho - amakuru aturuka muri DTOZH ahabwa ishami rishinzwe kugenzura ibikoresho bya elegitoronike (ECU), rikagira ibyo rihindura.

Ubushyuhe bukonje bukoreshwa mumodoka zose zigezweho, zifite igishushanyo kimwe nihame ryimikorere.

Ubwoko nigishushanyo mbonera yubushyuhe

Mu binyabiziga bigezweho (kimwe no mubikoresho bitandukanye bya elegitoroniki), ibyuma bikoresha ubushyuhe birakoreshwa, ibintu byoroshye birimo thermistor (cyangwa thermistor).Thermistor nigikoresho cya semiconductor irwanya amashanyarazi biterwa nubushyuhe bwayo.Hano hari thermistors hamwe nubushuhe bubi kandi bwiza bwubushyuhe bwo kurwanya (TCS), kubikoresho bifite TCS itari nziza, kurwanya biragabanuka hamwe nubushyuhe bwiyongera, kubikoresho bifite TCS nziza, kurundi ruhande, biriyongera.Uyu munsi, thermistors hamwe na TCS mbi ikoreshwa cyane, kuko iroroshye kandi ihendutse.

Muburyo, imodoka zose DTOZh nimwe murimwe.Ishingiro ryigishushanyo ni umubiri wicyuma (silinderi) gikozwe mu muringa, umuringa cyangwa ibindi byuma birwanya ruswa.Umubiri wakozwe muburyo igice cyacyo gihura nigitemba gikonje - dore thermistor, ishobora kongerwaho gukanda nisoko (kugirango ubone amakuru yizewe nurubanza).Mugice cyo hejuru cyumubiri hari aho uhurira (cyangwa guhuza) kugirango uhuze sensor numuzunguruko uhuye na sisitemu yamashanyarazi yikinyabiziga.Urubanza narwo rufite urudodo kandi uruzitiro rwa hexagon rwakozwe mugushiraho sensor muri sisitemu yo gukonjesha moteri.

Ibyuma byubushyuhe biratandukanye muburyo bihujwe na ECU:

• Hamwe numuyoboro usanzwe wamashanyarazi - sensor ifite umuhuza wa plastike (cyangwa guhagarika) hamwe nabahuza;
• Hamwe noguhuza imigozi - umubonano umwe hamwe nugufata ibyuma bikozwe kuri sensor;
• Hamwe na pin ihuza - pin imwe cyangwa spatula itangwa kuri sensor.

Ibyumviro byubwoko bwa kabiri nubwa gatatu bifite aho bihurira gusa, icya kabiri ni umubiri wa sensor, uhujwe n "" hasi "ya sisitemu yimashanyarazi yimodoka ikoresheje moteri.Ibyo byuma bikoreshwa cyane mubinyabiziga byubucuruzi namakamyo, kubidasanzwe, ubuhinzi nibindi bikoresho.

Ubushyuhe bukonje bushyirwa ahantu hashyushye cyane ya sisitemu yo gukonjesha moteri - mu muyoboro usohora umutwe wa silinderi.Ku modoka zigezweho, DTOZhS ebyiri cyangwa eshatu zishyirwaho icyarimwe, buri imwe ikora imirimo yayo:

• Ikimenyetso cya termometero (igipimo cy'ubushyuhe bwa coolant) nicyo cyoroshye cyane, gifite ubunyangamugayo buke, kubera ko gifasha gusa kureba ubushyuhe bwubushyuhe bwumuriro;
• Icyuma cya ECU ku isohokera ry'umutwe w'ikigo nicyo gikora cyane kandi gikora neza (hamwe n'ikosa rya 1-2.5 ° C), bigufasha gukurikirana ihinduka ry'ubushyuhe bwa dogere nyinshi;
• Imirasire isohora ibyuma - ibyuma bifasha ibyuma bifata ibyemezo bike, byemeza ko bizimya mugihe cyo kuzimya no kuzimya umuyaga ukonjesha.

Senseri nyinshi zitanga ibisobanuro byinshi kubyerekeranye nubushyuhe buriho bwumuriro wamashanyarazi kandi bikagufasha gukurikirana neza imikorere yacyo.

 

Ihame ryimikorere nu mwanya wa sensor yubushyuhe mumodoka

Muri rusange, ihame ryimikorere yubushyuhe bworoshye biroroshye.Umuvuduko uhoraho (mubisanzwe 5 cyangwa 9 V) ushyirwa kuri sensor, kandi voltage igabanuka kuri thermistor ukurikije amategeko ya Ohm (kubera kuyirwanya).Imihindagurikire yubushyuhe isaba impinduka mukurwanya thermistor (iyo ubushyuhe buzamutse, ubukana buragabanuka, iyo ubushyuhe bugabanutse, bwiyongera), bityo voltage igabanuka mukuzunguruka kwa sensor.Agaciro gapimwe k'umuvuduko wa voltage (cyangwa kuruta, voltage nyirizina mumuzunguruko wa sensor) ikoreshwa na termometero cyangwa ECU kugirango umenye ubushyuhe bwa moteri.

Kugirango ugenzure neza ubushyuhe bwumuriro wamashanyarazi, igikoresho cyihariye cyamashanyarazi gihujwe numuyoboro wa sensor - ibipimo bya termometero.Igikoresho gikoresha amashanyarazi abiri cyangwa atatu, hagati yacyo hari armature yimukanwa hamwe numwambi.Umuyaga umwe cyangwa ibiri utanga umurima uhoraho wa magneti, kandi umuyaga umwe ushyirwa mumuzunguruko wubushyuhe, bityo umurima wa magneti uhinduka bitewe nubushyuhe bukonje.Nkigisubizo cyimikoranire yumurima wa magnetiki uhoraho kandi uhinduranya mumirongo ihindagurika, itera armature kuzenguruka umurongo wacyo, bisaba guhinduka mumwanya wurushinge rwa termometero kumurongo wacyo.

Kugenzura imikorere ya moteri muburyo butandukanye no kugenzura sisitemu zayo, ibyasomwe bya sensor bihabwa ishami rishinzwe kugenzura ibikoresho bya elegitoronike binyuze mugenzuzi wabigenewe.Ubushyuhe bupimwa nubunini bwigabanuka rya voltage mumuzunguruko wa sensor, kubwiyi ntego mububiko bwa ECU hari imbonerahamwe yandikirana hagati ya voltage mumuzunguruko wa sensor n'ubushyuhe bwa moteri.Ukurikije aya makuru, algorithm zitandukanye zo gukora sisitemu nyamukuru ya moteri yatangijwe muri ECU.

Ukurikije ibyasomwe na DTOZH, imikorere ya sisitemu yo gutwika irahindurwa (guhindura igihe cyo gutwika), gutanga amashanyarazi (guhindura imiterere yimvange yumuyaga-mwuka, kugabanuka kwayo cyangwa gukungahaza, kugenzura inteko ya trottle), kuzenguruka gaze ya gaze na abandi.Na none, ECU, ukurikije ubushyuhe bwa moteri, ishyiraho umuvuduko wa crankshaft nibindi biranga.

Ubushyuhe bwubushyuhe kuri radiator ikonje bukora muburyo busa, bukoreshwa mugucunga umuyaga wamashanyarazi.Ku binyabiziga bimwe, iyi sensor irashobora guhuzwa nimwe nyamukuru kugirango irusheho kugenzura neza sisitemu zitandukanye.

Ubushyuhe bugira uruhare runini mu kinyabiziga icyo aricyo cyose gifite moteri yaka imbere, mugihe habaye gusenyuka, bigomba gusimburwa vuba bishoboka - gusa muriki gihe imikorere isanzwe yumuriro wamashanyarazi muburyo ubwo aribwo bwose.
