Ni izihe ngaruka bizagira ku modoka niba sensor ya camshaft yangiritse?
Sensor ya camshaft yangiritse ishobora guteza ingorane mu gutangira kwa moteri, guhindagura mu gihe cyo kuyikoresha, kugabanuka k'ingufu, kongera ikoreshwa rya lisansi, ndetse no gutera akamo k'urumuri rw'imodoka.
Utumenyetso tw’imikorere ya moteri mu gutangiza no kuyikoresha nabi
Ingorane mu gutangiza no gushyushya mu buryo butunguranye: Nyuma yuko sensor yangiritse, ECU ntishobora kumenya neza uko buri cylinder n'icyiciro cya camshaft bihagaze, bigatuma habaho igihe cyo gushyushya mu buryo butunguranye, bikagaragara ko bisaba kugerageza inshuro nyinshi gutangira, cyangwa ndetse no gutinda gutangira cyangwa kunanirwa gutangira. Mu bihe bikomeye, mu gihe cyo gutangira, hashobora kubaho guhindurirwa crankshaft no gusubizwa inyuma mu buryo butunguranye.
Kugabanuka kw'imikorere no kudahagarara:
Kunyeganyega gukabije kw'imodoka: Kimwe n'ikimenyetso cy'uko moteri yaguye nabi, kunyeganyega kuragaragara.
Moteri ihora ihagarara mu gihe cyo gutwara: Cyane cyane iyo imodoka ishyushye, ishobora guhagarara mu buryo butunguranye mu gihe itwaye cyangwa irimo kongeramo lisansi.
Kwihuta buhoro: Nyuma yo gukandagira accelerator, ingufu zisohoka zirahagarara, kandi ubusanzwe, umuvuduko wa moteri ugomba kurenga 2500 rpm kugira ngo urusheho kuba mwiza.
Igabanuka ry'imikorere y'ingufu n'ubukungu bw'ibikomoka kuri lisansi
Igabanuka rikomeye ry'ingufu: Bitewe nuko ECU itabona ibimenyetso bya camshaft neza, igihe cyo gutera lisansi n'igihe cyo gutwika ntibishobora guhuzwa n'imikorere ya silinda, bigatuma moteri inanirwa, kwihuta buhoro, no gutinda mu gihe cyo kuzamuka cyangwa kurenga. ECU ya zimwe muri moderi ishobora kandi kugabanya umuvuduko ntarengwa wa moteri kugira ngo irinde moteri.
Kongera ikoreshwa rya lisansi n'ibyuka bihumanya: Igenzura rya ECU ku ikoreshwa rya lisansi ntirikwiye, ritera ikoreshwa ry'ibikomoka kuri lisansi rikabije cyangwa ikoreshwa ry'ibikomoka kuri lisansi ridafite aho rihuriye, kandi ikoreshwa rya lisansi ryapimwe rishobora kwiyongeraho 15%-30%. Muri icyo gihe, gutwika kutuzuye bizatera umwotsi w'umukara uva mu muyoboro w'imyotsi, impumuro y'imyotsi yongera, kandi bishobora kongera umutwaro kuri sensor ya ogisijeni na catalytic converter y'inzira eshatu, hamwe n'ibyago byo kwangirika mu gihe kirekire.
Kurinda sisitemu n'ingaruka zishobora guterwa na mekanike
Gukoresha uburyo bwo kurinda amakosa: Itara rya moteri rihora ryaka (ubusanzwe rijyanye n'amakode y'ikosa nka P0340), kandi ECU izinjira muri ubwo buryo, ikagabanya ingufu zisohoka, kandi ishobora guhagarika imikorere nka valive timing (VVT). Muri iki gihe, imodoka ishobora kugenda intera ngufi gusa, ariko imikorere yayo ni mike cyane.
Ingaruka zishobora guterwa n'ibyangiritse bya tekiniki:
Kutagena igihe cyo gutwika: Bishobora gutera guturika, kandi uko igihe kigenda gihita, bizangiza silinda, piston, n'ibindi bice byayo.
Ukwiyongera kw'uburyo bwo gukoresha valve: ECU ntishobora kugenzura neza urwego rwa valve, ibyo bikaba bishobora kongera kwangirika kw'ibice bifitanye isano na yo.
Mu bihe bikomeye iyo sensor ya crankshaft nayo yananiwe, imodoka ishobora kunanirwa gutangira cyangwa guhagarara burundu mu gihe cyo kuyikoresha.
Disiki y'ikimenyetso ishyirwa hagati ya diode itanga urumuri (LED) na transistor y'amashanyarazi (cyangwa photodiode). Iyo umwobo wohereza urumuri kuri disiki y'ikimenyetso uzenguruka hagati ya LED na transistor y'amashanyarazi, urumuri rutangwa na LED ruzamurikirwa kuri transistor y'amashanyarazi, aho transistor y'amashanyarazi ikora, kandi ikusanya ryayo rigasohora urwego rwo hasi (0.1-0.3V) ； iyo igice cy'igicucu kuri disiki y'ikimenyetso kizenguruka hagati ya LED na transistor y'amashanyarazi, urumuri rutangwa na LED ntirushobora kumurika kuri transistor y'amashanyarazi, aho transistor y'amashanyarazi izima, kandi ikusanya ryayo rigasohora urwego rwo hejuru (4.8-5.2V). Iyo disiki y'ikimenyetso izenguruka ubudasiba, umwobo wohereza urumuri n'igice cy'igicucu bizanyurana hagati ya LED na transistor y'amashanyarazi, kandi ikusanya rya transistor y'amashanyarazi rizasohora urwego rwo hejuru n'urwo hasi. Iyo umugozi w’icyuma uzenguruka hamwe n’icyuma gishyushya n’icyuma gishyushya, umwobo wohereza urumuri n’igice cy’igicucu kiri kuri disiki y’ikimenyetso bizanyura hagati ya LED na transistor y’amashanyarazi, urumuri rutangwa na LED ruzamurikirwa kuri transistor y’amashanyarazi y’icyuma gishyushya ikimenyetso, kandi sensor y’ikimenyetso izatanga ibimenyetso bijyana n’aho icyuma gishyushya n’aho icyuma gishyushya ikimenyetso kiri.
Kubera ko crankshaft izunguruka inshuro ebyiri zose, sensor y'ikimenyetso cya G izatanga ibimenyetso 6 byo gukanda. Sensor y'ikimenyetso cya Ne izatanga ibimenyetso 360 byo gukanda. Kubera ko umurongo w'intera y'umwobo wohereza urumuri w'ikimenyetso cya G ari 60. Kuri buri dogere 120 zo gukanda, ikimenyetso cyo gukanda kirakorwa. Kubwibyo, ikimenyetso cya G gikunze kwitwa ikimenyetso cya 120. Igishushanyo n'ishyirwaho ryemeza ko ikimenyetso cya 120. gitangwa 70. (BTDC70.) mbere y'igice cyo hejuru cya silinda ya moteri. Ikimenyetso cyakozwe n'uruhande rw'urukiramende rufite uruhande rurerure rungana na 70. imbere y'igice cyo hejuru cya silinda ya 1 ya moteri, kugira ngo ECU ibashe kugenzura inguni yo gutera lisansi n'inguni yo gukanda. Kubera ko intera y'umwobo w'urumuri ku kimenyetso cya Ne ari 1. (Umwobo w'urumuri ufata 0.5. naho umwobo w'igicucu ugafata 0.5.), muri buri ruziga rw'ingufu, urwego rwo hejuru n'urwo hasi buri kimwe gifata 1. inguni yo kuzunguruka kwa crankshaft, naho ibimenyetso 360 bigereranya kuzunguruka kwa crankshaft ya 720. Buri dogere 120. z'izunguruka rya crankshaft, sensor ya G itanga ikimenyetso kimwe, naho sensor ya Ne itanga ibimenyetso 60.
