Fahimtar Kula da Matsi na Lantarki
A taƙaice dai, Na'urar Kula da Maƙurar Motsa Jiki (Electronic Throttle Control) tsarin sarrafa maƙurar ne wanda ke aiki ta amfani da siginar lantarki. Sau da yawa ana kiran wannan tsarin da drive-by-wire saboda direban ba ya "motsa" maƙurar kai tsaye da kebul, sai dai "yana aika umarni" ta hanyar firikwensin.
Idan direban ya danna fedar mai saurin motsawa, na'urar firikwensin da ke kan fedar (Accelerator Pedal Position Sensor/APPS) tana karanta nisan da pedal ɗin ke da shi. Ana aika wannan bayanin zuwa ECU. Sannan ECU tana ƙididdige buɗewar matsi da ta dace bisa ga abubuwa daban-daban - kamar saurin injin (RPM), nauyin injin, zafin injin, ko na'urar sanyaya iska tana kunne ko a kashe, da dabarun inganta amfani da mai - sannan ta umarci injin mai kunna wutar lantarki da ke jikin matsi don buɗe bawul ɗin matsi a wani kusurwa na musamman.
Saboda duk ana sarrafa shi ta hanyar lantarki, tsarin yana kuma da na'urar firikwensin matsayi na matsi (TPS) don tabbatar da cewa bawuloli suna buɗe kamar yadda aka umarta. A wata ma'anar, ETC tana aiki a cikin tsarin rufe-matsayi, tana ci gaba da gyara duk wani bambanci tsakanin yanayin manufa da na ainihi.
Babban Abubuwan da aka gyara na ETC
Domin fahimtar yadda yake aiki cikin sauƙi, ga abubuwan da ake samu gabaɗaya a cikin tsarin Kula da Matsewar Lantarki:
1. Feda mai amfani da firikwensin matsayi (APPS)
Wannan firikwensin yana maye gurbin wayoyi. Motoci da yawa suna amfani da firikwensin guda biyu (redundancy) don aminci, wanda ke bawa ECU damar kwatanta sigina da gano matsaloli.
2. ECU/ECM (Sashin Kula da Injin/Module)
Kwakwalwar tsarin, sarrafa shigarwar daga feda, na'urori masu auna injin, da sauran tsarin. ECU tana tantance madaidaicin buɗewar matsi ga kowane yanayi.
3. Jikin maƙurar lantarki
Ya ƙunshi bawul ɗin maƙulli, injin lantarki mai kunna wutar lantarki, da firikwensin matsayi na maƙulli (TPS). Motar tana motsa bawul ɗin bisa ga umarnin ECU.
4. Na'urori masu tallafi
Waɗannan sun haɗa da iska mai ƙarfi (MAF), matsin lamba mai yawa (MAP), zafin iska mai ɗaukar ciki (IAT), zafin sanyaya, na'urar firikwensin O2, na'urar firikwensin knock, da ƙari. Duk waɗannan suna taimaka wa ECU wajen yanke shawara mafi kyau game da matsi.
5. Tsarin aminci (yanayin gazawa/ƙarancin rauni)
Idan matsala ta faru, tsarin zai iya iyakance buɗewar maƙurar mota ta yadda motar za ta iya tafiya a hankali zuwa shagon gyara, amma har yanzu lafiya lau.
Yadda Sarrafa Matsi na Lantarki ke Aiki
Matakan aiki na ETC gabaɗaya sune kamar haka:
1. Direban yana danna feda mai.
2. APPS yana canza matsayin feda zuwa siginar lantarki (lambar wutar lantarki/dijital).
3. ECU yana karanta siginar, sannan ya haɗa ta da sauran bayanan firikwensin.
4. ECU tana ƙididdige buɗewar maƙurar da aka yi niyya (da kuma dabarun allurar mai da kunna wuta).
5. ECU tana aika sigina zuwa injin matsi don buɗe bawul ɗin bisa ga abin da aka nufa.
6. TPS tana aika ra'ayoyi kan ainihin matsayin matsi.
7. ECU tana kwatanta manufa idan aka kwatanta da ainihin kuma tana gyara idan ya cancanta.
Wannan tsari yana faruwa da sauri sosai (a cikin millise seconds), don haka amsawar pedal har yanzu tana jin kamar ta halitta.
Aikin Kula da Maƙulli na Lantarki
ETC ba wai kawai "maye gurbin kebul na throttle" ba ne. Wannan fasaha tana da ayyuka masu mahimmanci da yawa:
1. Daidaita samar da iska daidai
Injinan mai na zamani sun dogara sosai akan daidaitaccen haɗin iska da mai. Tare da ETC, ECU na iya buɗe maƙurar iska da cikakken daidaito, yana isar da iskar da ake buƙata. Sakamakon shine ƙarin konewa mai ƙarfi, amsawar injin mai santsi, da kuma ƙarin hayaki mai sarrafawa.
2. Ƙara ingancin mai
Domin ECU na iya inganta buɗewar maƙura dangane da yanayi, wannan tsarin yana taimakawa rage yawan amfani da mai. Misali, lokacin tuƙi akai-akai a kan hanya mai faɗi, ECU na iya zaɓar buɗewar maƙura mafi inganci fiye da kawai bin "kebul mai ja" kai tsaye.
3. Haɗawa da fasalulluka na aminci (sarrafa jan hankali da sarrafa kwanciyar hankali)
ETC yana bawa tsarin sarrafa jan hankali (TCS) da tsarin kula da kwanciyar hankali (ESC) damar rage karfin injin ba tare da dogaro da birki kawai ba. Idan tayoyi suka zame, ECU na iya rufe maƙurar nan take, wanda hakan zai inganta daidaiton abin hawa da kuma rage barazanar rasa iko.
4. Yana tallafawa sarrafa jiragen ruwa da kuma sarrafa jiragen ruwa masu daidaitawa
Tare da sarrafa jiragen ruwa, abin hawa dole ne ya kiyaye takamaiman gudu. Tare da ETC, ECU kawai yana daidaita maƙurar ta atomatik kamar yadda ake buƙata. Tare da daidaita sarrafa jiragen ruwa (ACC), tsarin zai iya daidaita gudu don bin abin hawa a gaba, duk wanda ke buƙatar maƙurar da kwamfuta ke sarrafawa.
5. Yana sassauta hanzarin aiki kuma yana ƙara jin daɗi
Saboda ECU na iya "tace" shigarwar direba, ana iya sa hanzarin ya yi laushi. Ana iya lura da wannan lokacin da motar ke tafiya a hankali a cikin cunkoson ababen hawa ko lokacin ajiye motoci, inda za a iya sa sarrafa feda ya yi laushi kuma ya rage yin motsi.
6. Ƙarin diyya ga kaya (AC, alternator, tuƙi na wutar lantarki)
Idan AC ɗin yana kunne, nauyin injin yana ƙaruwa kuma saurin rashin aiki yakan ragu. Tare da ETC, ECU na iya daidaita buɗewar maƙura ta atomatik don kiyaye rashin aiki mai ƙarfi ba tare da direban ya buƙaci danna feda mai haɓaka ba.
7. Sarrafa saurin aiki daidai gwargwado
A wasu tsofaffin tsarin, rashin aiki yana ƙarƙashin ikon sarrafa Idle Air Control Valve (IAC). A kan motocin ETC da yawa, ana iya sarrafa rashin aiki ta hanyar buɗe maƙurar iska kaɗan, sauƙaƙe abubuwan da ke cikinta da kuma sa ikon sarrafawa ya zama daidai.
8. Yana tallafawa yanayin tuƙi (Eco/Na al'ada/Wasanni)
Motoci da yawa na zamani suna da yanayin tuƙi. Waɗannan yanayin galibi suna canza taswirar pedal. Misali, yanayin Eco yana sa amsawar pedal ta yi laushi don amfani da mai, yayin da yanayin wasanni ke sa maƙurar ta fi ƙarfin amsawa cikin sauri. Wannan abu ne mai sauƙi saboda ECU ce ke sarrafa maƙurar.
Amfani da Rashin Amfanin ETC
Kelebihan:
- Babban daidaito a cikin daidaita wutar lantarki ta iska da injin
- Sauƙaƙe haɗewa tare da fasalulluka na aminci da ta'aziyya
- Ƙarin hayaki mai sarrafawa da kuma amsawar injin mai santsi
- Yana tallafawa fasahar zamani kamar ACC, TCS, ESC, da yanayin tuƙi
Kekurangan:
– Ya fi rikitarwa ta hanyar lantarki, don haka ganewar asali yana buƙatar kayan aikin scanning da kuma ƙwararren masani wanda ya fahimce shi.
- Alamomin wannan matsala na iya takaita wutar lantarki (yanayin rage gudu) saboda dalilai na tsaro.
- Wasu sassa sun fi tsada fiye da tsarin kebul (misali jikin na'urorin lantarki)
Duk da haka, a masana'antar kera motoci, fa'idodin ETC sun fi yawa, don haka wannan tsarin ya zama daidaitacce a cikin motoci da yawa.
Alamomin Matsalolin da ke tattare da Sarrafa Matsi na Lantarki
Wasu alamomin da aka saba gani idan ETC yana da matsala sun haɗa da:
– Hasken alamar injin (duba injin) yana kunne
– Jinkiri ko amsawar pedal ɗin gas
- Saurin aiki sama da ƙasa mara tabbas
– Motar tana jin kamar tana "girgiza" ko kuma ba zato ba tsammani ta rasa wutar lantarki
– Gargaɗi na musamman kamar “ETC”, “Mai Sarrafa Maƙura”, ko alamar maƙura suna bayyana.
– Motar tana shiga yanayin lanƙwasa don haka ba za ta iya hanzartawa yadda ya kamata ba.
Dalilan na iya bambanta: na'urar firikwensin pedal mara kyau, jikin maƙura mai datti, injin maƙura mai rauni, kebul na mahaɗin da ya lalace, ko matsala da ECU. A lokuta da yawa, jikin maƙura mai datti saboda maƙura mai gurɓata na iya tsoma baki ga sarrafawa, don haka tsaftacewa akai-akai bisa ga shawarwarin masana'anta na iya taimakawa.
Kammalawa
Tsarin Sarrafa Maƙulli na Lantarki tsarin sarrafa maƙulli ne na lantarki wanda ke maye gurbin kebul na maƙulli na gargajiya. ETC yana aiki tare da firikwensin pedal, ECU, injin kunna maƙulli, da na'urori masu auna martani don daidaita buɗe maƙulli daidai. Aikinsa ba wai kawai yana inganta aiki da ingancin mai ba ne, har ma yana samar da tushe don haɗa fasalulluka na aminci kamar sarrafa jan hankali da sarrafa kwanciyar hankali, da kuma fasalulluka na jin daɗi kamar sarrafa jiragen ruwa da nau'ikan hanyoyin tuƙi daban-daban.
Ta hanyar fahimtar ETC, masu motoci za su iya fahimtar dalilin da yasa motocin zamani suke jin daɗi, aminci, da kuma "wayo" a martanin da suke bayarwa ga fedar mai saurin gudu - da kuma abin da za su nema idan alamun matsala da tsarin suka bayyana.
