Basa guru remota yekutanga mota
Se "nzvimbo yetsinga" yesystem yemagetsi, module yekudzora mota yekutanga inoshanda sechinobatanidza chakakosha mirairo yemutyairi nekushanda kweinjini. Mabasa ayo anosanganisira kudzora simba, dziviriro yekuchengetedzwa, uye manejimendi ane hungwaru muzvikamu zvakasiyana-siyana.
Kubva pamaonero esimba rinobuda, module yekudzora injini (ECU) inobatanidza data kubva kuzvinhu zvakaita semasensa enzvimbo yecrankshaft uye masensa ekuyerera kwemhepo kuti igadzirise hupamhi hwepulse yeinjection yemafuta uye angle yepamberi yeignition nekumhanya kwemhinduro ye millisecond. Mumamiriro ekukurumidzira ekukurumidza, ECU ichawedzera vhoriyamu yeinjection yemafuta panguva imwe chete uye ichafambisa nguva yeignition, ichisimudzira simba reimperation ne15%-25%; mumamiriro ezvinhu asina basa, inochengetedza chiyero chemhepo-mafuta che14.7:1 kuburikidza nekudzora kwakavharika, ichivimbisa kushanda kwakasimba kweinjini uku ichiwedzera kuchengetedzwa kwemafuta ne8%-12%. Module yekudzora ignition (ICM), seswitch yemagetsi yemagetsi, inodzora zvakananga circuit yekutanga yeignition coil zvichibva pamirairo yeECU, ichigadzira magetsi ane voltage yakawanda kuti ape simba kuspark plug, ichishanda semutongi weinjini.
Basa rekuchengetedza ndiro rimwe basa guru remodule yekudzora start-up. Pakuona kutadza kwesensor, kuputika, kana zvimwe zvinhu zvisina kumira zvakanaka, ECU inochengetedza kodhi yekukanganisa nekukasika uye inoburitsa mwenje wedashboard. Muzviitiko zvakakomba, inomutsa modhi yekukamhina kuti ideredze kubuda kwemagetsi, ichidzivirira kukuvara kwakanyanya kuinjini. Module yekudzora muviri (BCM) inoshandisa network yeCAN kuti iwane dziviriro yakarongeka ye start-up logic. Kana kumhanya kwemotokari kwasvika 10 km/h, inokiya magonhi otomatiki, ichikonzera maalarm anonzwika uye anoona kana paine kupinda kwemotokari zvisiri pamutemo, uye inotodzivirira kutanga kwemotokari zvisiri pamutemo kuburikidza nesystem yekudzivirira kuba injini. Pamusoro pezvo, module yekudzora start-up ine kugona kwekutonga simba, ichibatanidza magetsi emidziyo yemagetsi yakagoverwa yechinyakare, ichideredza huwandu hwemawaya emagetsi neanopfuura 40%, ichideredza njodzi yekufamba kwenguva pfupi uye kusakara, uye ichivandudza mashandiro ekugadzirisa.
Zviratidzo zvekutadza kwemodule yekudzora yekutanga
Sezvo mota ichikura, module yekudzora mota inotanga inogona kusangana nematambudziko akasiyana-siyana nekuda kwekukwegura kwezvikamu kana zvikanganiso zvewaya, zvinonyanya kuoneka semhando nhatu: kutanga kusina kujairika, kushanduka kwesimba, uye kushandiswa kwesimba kusina kujairika.
Chinonyanya kuoneka ndechekuti injini haichakwanise kuvhurwa. Kana injini ikatadza kuvhurwa, inotadza kudzora nguva chaiyo yekugadzirwa, zvichikonzera matambudziko ekutanga injini kana kutotadza kubatidza zvachose. Kana ECU ikatadza kushanda zvakanaka kana kukanganisa ndangariro, izvi zvinozokonzera kutadza kushanda zvakanaka kwemirairo yekuisa injini uye mafuta, zvichikanganisa zvachose mashandiro esystem yekutanga. Mamwe mamodheru anogonawo kusangana nematambudziko ekutanga nekuda kwekutadza kushanda zvakanaka kweCAN communication, senge P00A8 fault code inoratidza kukanganiswa kwesignali pakati pemota, zvichiita kuti mota ikwanise kuregedza kugamuchira mirairo yeECU.
Kuchinja-chinja kwesimba remagetsi ndiko kuratidzwa kwakavanzika kwekutadza. Module yekupisa isina kunaka inokonzera kupisa kusina kukwana, zvichikonzera simba risina kukwana panguva yekushanda kwemotokari, kumhanya zvishoma nezvishoma, uye kunonoka kweinenge 0.5-1 sekondi mukuwedzera kumhanya; mumamiriro ezvinhu asina kumira, injini inosanganawo nekudengenyeka nguva nenguva, uye muzviitiko zvakakomba, ichadzima zvakananga. Data reECU sensor risingawanzoitiki rinogonawo kukonzera kusagadzikana kwesimba, semuenzaniso, kutsauka muchiratidzo chesensor yemhepo kunotungamira pakuverengerwa kwemafuta zvisiri izvo, zvichikonzera kukanganiswa kwesimba panguva yekuchinja kwemutoro.
Kushandiswa kwesimba zvisina kujairika uye kuburitswa kwemhepo ndizvo zvinokonzerwa nekutadza. Kushandiswa kwemagetsi kusina kunaka kuchaita kuti mafuta asashande zvakanaka, zvichiwedzera kushandiswa kwemafuta ne10%-15%, uye zvichikonzera kuti carbon monoxide nehydrocarbon zvipfuure mwero wenguva nenguva ka2-3. Kana ECU ikapinda muchimiro chekukamhina, icharamba ichishanda zvakanaka nekudzikamisa huwandu hwemafuta anoshandiswa, kunyangwe ichigona kudzivirira kukuvara kweinjini, ichaita kuti mafuta awedzere kuwedzera, uye mune mamwe mamodheru, kushandiswa kwemafuta kunogona kutopetwa kaviri.
Kuongororwa kwezvikanganiso uye nzira dzekuzvigadzirisa nadzo
Kana paine zvikanganiso zvekutanga kwemodule yekudzora, nzira yekugadzirisa matambudziko ine mativi akawanda inosanganisa kuongorora kodhi yezvikanganiso, kuona zviratidzo, uye kuyedzwa kwezvikamu inofanira kushandiswa. Mukuongorora kwehunyanzvi, nzira yedambudziko inotanga yaonekwa nekuverenga kodhi dzezvikanganiso kuburikidza neOBD-II. Makodhi P0351-P0358 anonongedzera zvakananga kuzvikanganiso zvemodule yekupisa, nepo P00A8 ichiratidza kutaurirana kusingawanzoitiki kweCAN. Zvadaro, waveform yemagetsi ekutanga yemodule yekupisa inoonekwa uchishandisa oscilloscope. Kana waveform ichiratidza ruzha kana kukanganiswa, zvinogona kusimbiswa kuti zvikamu zvemukati zvemodule zvakakuvara. Kune zvikanganiso zveECU, zvakakosha kutarisa zvakare kana voltage yedunhu remagetsi iri mukati mehuwandu hwakajairika hwe13.5-14.5V, uye panguva imwe chete, ongorora kana paine kutsauka muzviratidzo zve sensor kuburikidza nekuongorora kwe data flow.
Munguva yekugadzirisa zuva nezuva, varidzi vemotokari vanogona kugamuchira yambiro yekutanga nekuona zviitiko zvisina kujairika. Kana mota ikasangana nekunonoka kutanga kwemotokari kweanopfuura masekondi matatu, idling vibration amplitude inodarika 50 rpm paminiti, kana kuwedzera kamwe kamwe kwekushandiswa kwemafuta kweanopfuura 10%, zvakakosha kuenda kunzvimbo yehunyanzvi kuti inoongororwa nekukurumidza. Panguva yekugadzirisa, zvakakosha kucherechedza kuti kutsiva ignition module kunoda kuisa high-temperature conductive silicone grease kuti ive nechokwadi chekuti kupisa hakuchaperi, uye ECU programming inofanira kushandisa chirongwa chepakutanga chakafanana nefekitori kudzivirira zvikanganiso zvechipiri zvinokonzerwa nekusawirirana kwema parameter. Pamusoro pezvo, kuchenesa nguva dzose sensor carbon deposits uye kutarisa kusimba kwekubatanidza wiring harness kunogona kuderedza mwero wekuitika kwezvikanganiso mu start control module. Rugwaro rwuri pamusoro runotsanangura mashandiro makuru, zvikanganiso zvakajairika uye zvirongwa zvekupindura zve start control module yemotokari, zvichifukidza zvese technical parameters uye mazano ekugadzirisa anoshanda. Inogona kupa referensi kune vashandi vekugadzirisa mota uye zvakare kubatsira varidzi vemotokari kunzwisisa mashandiro esystem yekutanga yemotokari.
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
