"Sensor y'ibidukikije by'imodoka" bivuze iki?
Utwuma tw’ibinyabiziga dupima ubushyuhe bw’ikirere, ubusanzwe tuvuga utwuma tw’ubushyuhe bw’ikirere, ari byo bikoresho biri mu modoka bikoreshwa mu gupima ubushyuhe bw’ikirere cyo hanze. Bikora nk' "utwuma tw’ubushyuhe" bw’imodoka, bigafasha sisitemu z’ikoranabuhanga z’imodoka gusobanukirwa imiterere y’ikirere cyo hanze.
Akamaro k'ingenzi k'icyuma gipima ubushyuhe bw'ibidukikije ni ugupima ubushyuhe bwo hanze no gutanga amakuru ku cyuma gipima ubushyuhe (ECU). Iki cyuma gikoresha ikoranabuhanga rigezweho (thermistor), agaciro kacyo gahinduka bitewe n'ubushyuhe, kigahindura ikimenyetso cy'ubushyuhe kikaba ikimenyetso cy'amashanyarazi hanyuma kikacyohereza kuri ECU. Ubusanzwe gishyirwa imbere y'ikinyabiziga (nk'urukuta rw'ikigega cy'amazi cyangwa agasanduku k'inyuma) kugira ngo kimenye neza ubushyuhe bw'ibidukikije.
Iyi sensor ni ingenzi cyane kuri sisitemu nyinshi z'imodoka:
Sisitemu yo gukonjesha: ECU ihindura ubushyuhe cyangwa ubukonje bitewe n'itandukaniro riri hagati y'ubushyuhe bwo hanze n'ubwo imbere kugira ngo ikomeze kuba nziza mu kazu.
Gucunga moteri: Bifasha guhindura ibipimo nko gukoresha lisansi n'igihe cyo gutwika kugira ngo moteri ikore neza ku bushyuhe butandukanye.
Sisitemu z'umutekano wa batiri: Mu modoka zikoresha amashanyarazi, bifasha mu gucunga ubushyuhe bwa batiri; binagira ingaruka ku ngamba nko guhagarika imodoka mu buryo bwikora, bikongera umutekano no gukoresha neza ingufu.
Iyo sensor inaniwe, ishobora gutuma habaho imikorere idahwitse ya moteri cyangwa igatuma moteri ikora nabi. Kubwibyo, ni ngombwa kugenzura buri gihe amashanyarazi, imiyoboro y'insinga, n'agaciro k'ubudahangarwa kugira ngo urebe ko ari ibisanzwe.
Utwuma dupima ibidukikije by’imodoka, cyane cyane utwuma dupima ubushyuhe bw’ibidukikije, ni bimwe mu bigize sisitemu y’ikoranabuhanga yo kugenzura imodoka, ahanini bishinzwe kumenya ubushyuhe bw’ibidukikije hanze no guhindura amakuru mo ibimenyetso by’amashanyarazi kugira ngo yoherezwe muri ECU kugira ngo ishyigikire kugenzura neza sisitemu nyinshi.
Muri sisitemu yo gukonjesha, sensor igenzura ubushyuhe bwo hanze, maze ECU igahindura inshuro ya compressor yo gukonjesha, ubushobozi bwo gukonjesha, cyangwa imbaraga zo gushyushya hashingiwe ku itandukaniro riri hagati y'ubushyuhe bw'imbere n'ubwo hanze. Urugero, yongera ubukonje iyo bushyushye kandi igatangira gushyushya iyo bukonje, bigatuma ubushyuhe bw'imbere burushaho kuba bwiza kandi bwihuse.
Ku bijyanye no gucunga moteri, amakuru y’ubushyuhe atangwa na sensor afasha ECU kunoza ingamba zo gukora, nko kongera ingano y’ibikomoka kuri lisansi kugira ngo byorohere gutangira no kugabanya kwangirika ku bushyuhe buri hasi, no guhindura umuvuduko w’umufana ukonjesha n’ifungura rya thermostat ku bushyuhe bwinshi kugira ngo hongerwe uburyo ubushyuhe bukwirakwira, bityo binoze uburyo lisansi ikoreshwa neza kandi ihamye.
Muri sisitemu yo gucunga bateri (cyane cyane mu modoka zikoresha amashanyarazi), sensor ikurikirana ingaruka z'ubushyuhe bwo hanze ku bikorwa bya bateri, maze ECU ihindura ingamba zo gusharija/gusohora umuriro cyangwa uburyo bwo gucunga ubushyuhe bwo gutangira, ikarinda ubushyuhe bukabije cyangwa kugabanuka k'imikorere ku bushyuhe buri hasi, yongerera igihe bateri imara kandi ikarinda umutekano.
Byongeye kandi, amakuru ajyanye n'ibipimo by'imodoka afasha mudasobwa itwara imodoka, sisitemu yo kuyobora imodoka mu kwerekana ubushyuhe bw'ibidukikije, kandi mu binyabiziga bimwe na bimwe, bikagira uruhare mu gutahura urubura ku muhanda kugira ngo birusheho guteza imbere umutekano w'imodoka.
Ubusanzwe iyi sensor ikoresha thermistors za NTC, zishyirwa ahantu nka bumper y'imbere kugira ngo hirindwe ko habaho kubangamira amasoko y'ubushyuhe, kandi ubuziranenge bwayo bugira ingaruka zitaziguye ku mikoranire myiza ya sisitemu nyinshi.
Utwuma dupima ibidukikije by'imodoka (nk'utwuma dupima umwuka wa ogisijeni, utwuma dupima ubushyuhe bw'amazi, utwuma dupima imvura, nibindi) dukoreshwa mu kugenzura ibipimo by'ibidukikije imbere n'inyuma y'imodoka, kandi amakosa ashobora kugira ingaruka ku mikorere ya moteri, kugenzura imyuka ihumanya ikirere, cyangwa uburyo bwo gufasha gutwara imodoka.
Impamvu z'amakosa ziratandukanye, cyane cyane zirimo:
Ibintu bifitanye isano n’ibidukikije: Ubushyuhe bukabije, ubushuhe, ivumbi, cyangwa kwibira mu mazi bishobora gutuma ibice by’ibikoresho bishaza, bigahinduka, cyangwa bikagira imiyoboro migufi y’amashanyarazi. Urugero, ubushyuhe bwinshi bwihutisha gusaza kw’ibikoresho by’umwuka wa ogisijeni, kandi ahantu hatose hatera ingese.
Ibibazo by'amashanyarazi: Imiyoboro migufi, imiyoboro ifunguye, gukora nabi k'amashanyarazi, cyangwa ihindagurika ry'amashanyarazi bishobora kubangamira uburyo bwo kohereza amajwi, bigatuma sensor inanirwa gukora neza.
Kwangirika kwa mekanike: Kugongana, guhindagura, cyangwa gushyiraho nabi bishobora gutuma sensor yimuka cyangwa kwangirika kw'imiterere yayo y'imbere, cyane cyane ku byuma bipima bishyirwa kuri chassis cyangwa amapine.
Umwanda n'ifunga: Kwirundanya kw'umukungugu, amavuta, cyangwa uduce twa karuboni bishobora gutwikira agace gapima sensor, bikabangamira uburyo ibidukikije bibona. Urugero, sensor ya ogisijeni yafunzwe itera guhindagurika kw'ibimenyetso.
Inenge zo gusaza no gukora: Gukoresha igihe kirekire bitera kwangirika k'imikorere y'ibice, cyangwa hashobora kubaho inenge mu byuma bipima ubwabyo, bishobora gutuma bicika intege hakiri kare.
Ibimenyetso by'ikosa biratandukanye bitewe n'ubwoko bwa sensor. Urugero, kunanirwa kwa sensor ya ogisijeni bishobora gutuma lisansi ikoreshwa cyane ndetse n'imyuka ihumanya ikabije; sensor y'ubushyuhe bw'amazi idasanzwe ishobora gutuma imiterere y'ubushyuhe bw'amazi idasobanutse neza; sensor y'imvura idafite ishingiro ishobora kugira ingaruka ku mikorere ya sensor y'ikirahure cyikora.
Gusuzuma no gukemura ikibazo bisaba iperereza rihamye: Ubwa mbere, emeza ikibazo usoma kode z'ikosa, kandi urebe aho ibyuma bihurira, insinga, n'amashanyarazi; koresha multimeter ya digitale ifite impedance nyinshi kugira ngo umenye, wirinde gukoresha ibikoresho byo mu bwoko bwa pointer cyangwa "uburyo bwo gushwanyaguza". Fata ingamba ku byuma bitandukanye, nko gusukura cyangwa gusimbuza sensor ya ogisijeni, guhindura aho throttle ihagaze. Mu gihe cyo gukora, witondere uburinzi kugira ngo wirinde ko ECU itoha cyangwa ngo imiyoboro igabanuke.
Kwirinda bisaba gushyira imbaraga mu kubungabunga buri munsi: Kugenzura buri gihe uko ibyuma bipima imiterere n'uko insinga zihagaze, kwirinda guhindura ibikoresho bishobora gutera ikibazo cy'amashanyarazi; kwitondera imiterere y'umuhanda mu gihe utwaye imodoka, kugabanya ibyago byo kugongana; kubungabunga imodoka buri gihe no gusukura vuba umwanda ukikije ibyuma bipima amashanyarazi.
Niba ushaka kumenya byinshi, komeza usome izindi nkuru kuri uru rubuga!
Duhamagare niba ukeneye ibyo bicuruzwa.
