Mota inogogodza sensor basa
Basa guru remotokari inogogodza sensor ndeyekuona kugogodza chiitiko cheinjini, uye kudzivirira kugogodza nekugadzirisa iyo ignition yepamberi Angle, kuitira kuchengetedza injini kubva mukukuvadzwa. a
Iyo yekugogodza sensor inoshandura ma mechanic vibrations einjini kuita masaini emagetsi ayo anotumirwa kune yemagetsi control unit (ECU). Iyo ECU inogadzirisa iyo iginition yepamberi Angle zvinoenderana nechiratidzo chakagamuchirwa kuti udzivise kuenderera kunoitika kwe detonation. Iyo yekugogodza sensor inowanzo shandisa piezoelectric ceramic tekinoroji. Injini painozununguka, iyo ceramic inomanikidzwa uye yakaremara kuti ibudise chiratidzo chemagetsi, chinotumirwa kuECU kuburikidza newaya yakavharidzirwa kuti igadziriswe.
Nheyo yekushanda yekugogodza sensor inobva pane piezoelectric effect, apo injini inogogodza, piezoelectric ceramics mukati me sensor inosvinwa, ichiita chiratidzo chemagetsi. Aya masaini anotumirwa kuECU, iyo inogadzirisa yekubatidza kumberi kweAngle zvichibva pane yakachengetwa data kudzivirira kugogodza. Uye zvakare, kugogodza masensa anogona kuona kumhanya uye chinzvimbo cheinjini, ichipa ruzivo rwakawanda kubatsira kukwirisa injini kuita.
Iyo yekugogodza sensor inowanzoiswa mune imwe nzvimbo mujini block, senge pakati pe2 uye 3 masilinda echina-cylinder muchina kana pakati pe1 uye 2 cylinder uye 3 kana 4 cylinder. Nzvimbo yaro yekukwira inovimbisa kubatwa kwakasimba kwediki injini vibrations uye kugogodza.
Kana sensor yekugogodza ikatadza, kunyangwe ikasaita kuti injini itadze kutanga, inokonzeresa matambudziko akadai sejitter yejitter, kupera simba, kuderera kwehupfumi hwemafuta, uye magetsi emagetsi. Naizvozvo, kushanda kwakakodzera kwekugogodza sensor kwakakosha pakuita kweinjini.
Mota inogogodza sensor mudziyo wakaiswa painjini block, inonyanya kushandiswa kuona kugogodza kweinjini. Kune akawanda marudzi ekugogodza masensa, anonyanya kuzivikanwa ayo anosanganisira magnetostrictive uye piezoelectric ceramic.
Mhando uye chimiro chekugogodza sensor
Magnetostrictive: ine magineti musimboti, magineti echigarire uye induction coil. Injini painozunguzika, iyo magineti musimboti inoshanduka, zvichikonzera shanduko yemagnetic flux muinduction coil, zvichikonzera induced electromotive force .
piezoelectric ceramic : Kana injini ichizununguka, ceramic mukati inosvinwa kuti ibudise chiratidzo chemagetsi. Nekuti iyo chiratidzo haina kusimba, tambo yekubatanidza inowanzoputirwa netambo yakavharidzirwa.
piezoelectric resonance : yakaiswa pachikamu chepamusoro chemuviri weinjini, kushandiswa kwepiezoelectric effect kushandura mechanical vibration kuita masaini emagetsi. Kana iyo yekugogodza vibration frequency ichienderana neyakajairwa frequency ye sensor, resonance phenomenon ichaitika, uye iyo yakakwira yekugogodza chiratidzo chemagetsi ichabuditswa kuECU, zvichienderana nekuti iyo ECU ichagadzirisa nguva yekudzima kuti usagogodza.
Iyo yekugogodza sensor inoshanda sei
Iyo inogogodza sensor inonzwa kuzununguka uye ruzha rweinjini uye inoashandura kuita masaini emagetsi anotumirwa kune injini control unit (ECU). Iyo ECU inogadzirisa iginition yepamberi Angle zvinoenderana nechiratidzo chakagamuchirwa kudzivirira kuitika kwe detonation. Iyo chaiyo yekushanda musimboti ndeiyi inotevera:
Magnetostrictive : injini vibration inokonzeresa kuti magineti musimboti ichinje, ichichinja magineti flux muinduction coil, zvichikonzera induced electromotive force.
piezoelectric ceramic : injini painozununguka, piezoelectric ceramic inosvinwa kuti ibudise chiratidzo chemagetsi, ECU inogadzirisa nguva yekubatidza zvinoenderana nechiratidzo.
piezoelectric resonance type : kana kugogodza kubhuroka frequency kuchienderana neakajairika frequency ye sensor, chiitiko che resonance chinoitika, uye yakakwira yekugogodza chiratidzo voltage inobuda kuECU.
Basa rekugogodza masensa mumotokari
Basa guru rekugogodza sensor ndeyekuyera jitter degree rejini. Kana injini ikaburitsa kugogodza, siginecha yemagetsi inotumirwa kuECU, uye ECU inogadzirisa iyo yekuvhenekesa kumberi kweAngle nenzira kwayo kudzivirira kugogodza. Kugogodza kunogona kukonzera kukuvara kweinjini, saka kugogodza masensa kunoita basa rakakosha kuchengetedza injini.
