Mutongi weKuchaja: Mutongi Asingaonekwe uye Mutsigiri weMhosva weSisitimu yeMagetsi eMota
Muhurongwa hwemagetsi hwakaoma hwemotokari, kunyange zvazvo chinodzora kushaja chisina kuoneka seinjini kana giya regiya, chinoita basa guru. Chakafanana nechinodzora chakarurama chinogara chichigadzirisa maparameter zvichienderana nemamiriro ekushanda kweinjini kuti chive nechokwadi chekuti simba rinobuda zvakanaka uye rakagadzikana kubva mumotokari.
Basa guru remutongi wekuchaja mota
Chinodzora kushaja mota chakakamurwa kuva ma "power system charging controllers" uye ma "injini phase controllers", chimwe nechimwe chichiita mabasa acho ekuchengetedza mashandiro emota.
Mumagetsi emota, muchina wekuchaja une basa guru rekugadzirisa voltage. Kumhanya kweinjini kwakafara, uye voltage inobuda yejenareta inochinja zvinoenderana. Midziyo yemagetsi iri mukati memota, yakadai sema headlights, ma audio system, uye kufamba kwemota, zvese zvinoda voltage yakagadzikana kuti ishande zvakanaka. Muchina wekuchaja unodzora saizi yemagnetic field current mukati mejenareta, uchiwedzera magetsi kana kumhanya kweinjini kwakaderera uye unoideredza kana kumhanya kwacho kwakakwira, uchidzikamisa voltage inobuda yejenareta pamutengo wakarongwa (kazhinji inenge 14.0V) kuona kuti michina yemagetsi yemota haina kukanganiswa nekuchinja kwevoltage. Panguva imwe chete, inewo mabasa ekudzivirira magetsi ekuchaja akawandisa uye kudzima magetsi ekudzokera shure, kudzivirira kukuvara kwebhatiri nejenareta nekuda kwemagetsi ekuchaja akawandisa, kudzivirira bhatiri kuburitsa magetsi zvakanyanya uye kukuvara kwejenareta, uye kuwedzera hupenyu hwebhatiri nejenareta.
Mutongi wechikamu cheinjini anotarisa pakuvandudza mashandiro einjini. Semuenzaniso, mutongi wechikamu cheVVT anogona kugadzirisa chikamu checamshaft zvichienderana nekuchinja kwemamiriro ekushanda kweinjini, nokudaro achigadzirisa huwandu hweinjini nehwekubuda, achidzora nguva yekuvhura nekuvhara uye kona yemavharuvhu. Mumamiriro ekumhanya kwakaderera kana kwemutoro wakaderera, mutongi wechikamu cheinjini anofambisa zvakanaka nguva yekuvharwa kwevharuvhu yekupinda, achigadzira kurovera kweinjini kwenguva pfupi, achivandudza turbulence uye swirl effect mu cylinder, achiita kuti musanganiswa uve wakafanana, achivandudza kugadzikana kwekupisa, uye achisimudzira low-speed torque output, zvichiita kuti mota itange zvakanaka; kana injini iri pa high speed kana high-load mamiriro, inononotsa nguva yekuvharwa kwevharuvhu yekupinda, ichiwedzera urefu hwe intake stroke, ichibvumira mhepo yakawanda kupinda mu cylinder, uye ichibatana nenguva yekuiswa kwemafuta gare gare kuti igadzire musanganiswa wakaoma, ichiwedzera simba reinjini, ichizadzisa zvinodiwa zvekumhanyisa mota kana kutyaira nekukurumidza.
Zviratidzo zvinowanzoonekwa zvekukundikana kwechinodzora chekuchaja mota
Kana chinodzora kushaja mota chikatadza kushanda, chinoratidza kusarongeka kwezvinhu zvakawanda mumotokari.
Kana chinodzora kushaja system yemagetsi chikatadza kushanda, chinhu chinowanzoitika ndechekuti jenareta harigadzi magetsi. Panguva ino, mwenje wechiratidzo chebhatiri padashboard unobatidza, izvo zvinowanzo kukonzerwa nekukanganisika kwe transistor yemagetsi inogadzirisa magetsi kana kuti transistor yeDarlington. Panogonawo kuva nemamiriro ekugadzirwa kwemagetsi akawandisa, izvo zvinoita kuti bhatiri riwedzere kushaja, zvichikanganisa hupenyu hwebhatiri, uye zvichitokonzera kukuvara kwebhatiri, zvichiratidzwa sevoltage yebhatiri iri pasi pe10V, zvichiita kuti mota iome kutanga. Pamusoro pezvo, chinodzora jenareta chakakanganisika chichaitawo kuti mota iomerwe nekumhanya, kuwedzera kushandiswa kwemafuta, uye kukanganisa zvakanyanya mashandiro emotokari.
Kukundikana kwemutongi wechikamu cheinjini kuchakanganisa zvakananga simba reinjini uye kushandiswa kwemafuta. Kana injini ikakundikana, injini inogona kunge isina kugadzikana, ichizunguzika zvakanyanya, iine torque shoma, uye mota ichitanga kufamba zvishoma nezvishoma; kana mota ikamhanya zvakanyanya, simba reinjini harigone kusvika padanho rakajairika, uye kumhanya kwemotokari kuchaderera. Panguva imwe chete, nekuda kwekudzikira kwekushanda kwemoto, kushandiswa kwemafuta mumotokari kuchawedzera zvakanyanya, uye utsi hunogona kupfuura mwero wakatarwa.
Kuongorora uye kugadzirisa kutadza kwemutongi wekuchaja mota
Kana paine kutadza kwekutonga kwekuchaja kwemagetsi, nzira dzehunyanzvi dzekuongorora dzinogona kushandiswa pakuongorora. Semuenzaniso, pakuongorora mota, magetsi eDC anoshanduka e10 - 20V (kana 20 - 40V) anogona kushandiswa, akabatana zvichienderana nenzira dzakatarwa, uye kuchinja kwepointer yemita iripo kana mamiriro ebharubhu kunoonekwa kuti kuyera voltage inotonga yemutongi. Kana voltage isiri mukati me13.6 - 14.5V, zvinoratidza kuti mutongi haana kunaka. Kazhinji, ma-integrated circuit regulators haagone kugadziriswa kana akuvara uye anogona kutsiviwa chete. Paanotsiva, zvakakosha kusarudza mutongi akakodzera anoenderana neapakutanga maererano nevoltage yezita, ground polarity, nezvimwe zvinodiwa. Ma voltage uye grounding form emutongi nejenareta zvinofanirawo kunge zvakafanana.
Kuongororwa kwezvinodzora injini zvechikamu chemodulation kwakaoma uye kazhinji kunoda kushandiswa kwemichina yekuongorora mota yehunyanzvi. Kuverenga makodhi ekutadza einjini, kuongorora data rechikamu che camshaft, nezvimwewo. Kana kutadza kwaonekwa, kune vanodzora hydraulic-driven phase, zvingave zvakakosha kutarisa kana hydraulic oil circuit yakavharwa uye kana sealing ring yakakuvara; kune vanodzora mafambiro emagetsi, zvakakosha kutarisa kana mota nedunhu rekudzora zviri zvakajairika. Mune zvimwe zviitiko, zvikamu zvekutonga mafambiro zvakakuvara zvinoda kutsiviwa.
Pfungwa huru dzekuchengetedza mota dzemazuva ese
Kuti kuderedze kuitika kwekutadza kushanda kwemota, kugadzirisa kwezuva nezuva kwakakosha. Chekutanga, kuongororwa nguva nenguva kwemagetsi emotokari kunodiwa kuti tive nechokwadi chekuti waya dziri pakati pejenareta neregulator dzakachengeteka, kudzivirira zvikanganiso zvakaita sekuchaja kusina kugadzikana nekuda kwewaya dzisina kugadzikana. Chechipiri, zvichienderana nezvinodiwa nebhuku rekugadzirisa mota, gara uchitsiva mafuta einjini, mafirita emhepo, nezvimwewo, kuti uve nechokwadi chekuchena kwemukati meinjini uye kupa nzvimbo yakanaka yekushanda ye phase regulator. Pamusoro pezvo, kana uchitsiva bhatiri kana jenareta, sarudza zvigadzirwa zvinoenderana nemotokari kuti usakuvadze modulator nekuda kwekusaenderana kwevoltage kana zvimwe zvinetso.
Sechinhu chakakosha chemagetsi emotokari, mamodulators emotokari haafanirwe kurerutswa. Kunzwisisa mashandiro awo, zviratidzo zvezvikanganiso, uye nzira dzekuongorora nekugadzirisa zvinogona kubatsira varidzi vemotokari kuona nekugadzirisa matambudziko nekukurumidza, zvichiita kuti mota ishande zvakanaka uye kuwedzera hupenyu hwayo.
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonerei kana muchida zvigadzirwa zvakadaro.
