Chii chinonzi mota camshaft sensor?
Sensor yenzvimbo yeCamshaft inoita basa rakakosha muinjini yemotokari, basa guru nderekuunganidza chiratidzo chenzvimbo yecamshaft uye kuchiisa kuyuniti yekudzora yemagetsi (ECU) kuitira kuti ione nguva yekupisa uye nguva yekupinza mafuta. Nekuona nzvimbo yekutenderera yecamshaft, sensor inoona nguva yekuvhura nekuvhara kwevharuvhu, nokudaro ichikwanisa kudzora injini nemazvo.
Pfungwa yekushanda kwesensa yenzvimbo ye camshaft yakavakirwa pa electromagnetic induction kana photoelectric induction technology. Kana camshaft ichitenderera, sensa inoona bump kana notch mu camshaft uye inogadzira chiratidzo chemagetsi chinoenderana. Mushure mekugamuchira zviratidzo izvi, ECU inosarudza nguva yekupisa uye nguva yekuisirwa mafuta kuburikidza nekuverenga nekugadzirisa, kuitira kuti iwane kutonga kwakarurama kweinjini.
Kururama uye kuvimbika kwemasensa enzvimbo ye camshaft kwakakosha pakushanda zvakanaka kweinjini uye kuchengetedza mafuta. Kana sensa ikakundikana, zvinogona kukonzera kupisa kusina kunaka, kudzikira kwekuchengetedza mafuta, uye pamwe injini isingashande nemazvo. Saka, kuongororwa nguva dzose uye kugadziriswa kwesensa yenzvimbo ye camshaft kwakakosha zvikuru.
Sensor yecamshaft inonyanya kushandiswa kuona nzvimbo yecamshaft uye kumhanya kwayo, kuona kuti injini inoshanda zvakanaka. Sensor yeCamshaft, inozivikanwawo seCamshaft Position Sensor (CPS) kana kuti Cylinder Identification Sensor (CIS), basa rayo guru nderekuunganidza zviratidzo zvenzvimbo yevalvu camshaft. Zviratidzo izvi zvinoiswa muElectronic Control Unit (ECU). Kubva pazviratidzo izvi, ECU inokwanisa kuona TDC yekumanikidzwa kwecylinder 1 yekudzora mafuta, kudzora nguva yekupisa uye kudzora deflagration .
Maumbirwo uye musimboti wekushanda
Kune mhando dzakawanda dzemasensa enzvimbo dzecamshaft, anosanganisira photoelectric nemagnetic induction. Photoelectric sensor inonyanya kuumbwa nesignal disk, signal generator uye distributor, uye inogadzira signal kuburikidza nelight-emitting diode uye photosensitive transistor. Magnetic induction type inoshandisa Hall effect kana musimboti we magnetic induction kugadzira masignal, ayo anowanzo kamurwa kuita Hall type ne magnetoelectric type .
Nzvimbo yekuiswa
Sensor yenzvimbo yecamshaft inowanzoiswa kumberi kwechikamu checamshaft, yakatarisana nemberi kwechikamu cheinput ne exhaust camshaft. Dhizaini iyi inoita kuti sensor ikwanise kuunganidza chiratidzo chenzvimbo yecamshaft nemazvo.
Kushanda kwezvikanganiso uye kukanganisa
Kana sensor ye camshaft ikatadza kushanda, zviratidzo zvinowanzoonekwa zvinosanganisira kuoma kutanga mota, kuoma kudira mafuta kana kumira kana ichipisa, kushandiswa kwemafuta kwakawanda, simba risina kukwana uye kusamhanya zvakanaka. Zviratidzo izvi zvinokonzerwa nekusakwanisa kweECU kudzora mafuta nemazvo uye nguva yekupisa.
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonerei kana muchida zvigadzirwa zvakadaro.
