Basa re sensor rinogogodza mota
Basa guru remota inogogodza injini nderekuona kugogodza kweinjini, uye kudzivirira kugogodza nekugadzirisa Angle yekupisa, kuitira kudzivirira injini kubva mukukuvadzwa.
Sensor yekugogodza inoshandura kutenderera kwemagetsi kweinjini kuita masaini emagetsi anotumirwa kuyuniti yekudzora magetsi (ECU). ECU inogadzirisa Angle yekupisa zvichienderana nechiratidzo chinogamuchirwa kudzivirira kuitika kwekuputika kunoramba kuripo. Sensor yekugogodza inowanzo shandisa tekinoroji ye piezoelectric ceramic. Kana injini ikazununguka, ceramic inomanikidzwa uye inokanganisika kuti ibudise chiratidzo chemagetsi, icho chinotumirwa kuECU kuburikidza newaya yakavharirwa kuti chigadzirwe.
Pfungwa yekushanda kweknock sensor yakavakirwa pamhedzisiro yepiezoelectric, injini painogogodza, piezoelectric ceramics dziri mukati mesensor dzinodzvanywa, zvichigadzira chiratidzo chemagetsi. Zviratidzo izvi zvinotumirwa kuECU, iyo inogadzirisa Angle yekupisa zvichibva padata rakachengetwa kudzivirira kugogodza. Pamusoro pezvo, knock sensors dzinogona kunzwa kumhanya nenzvimbo yeinjini, zvichipa ruzivo rwakawanda kuti zvibatsire kugadzirisa mashandiro einjini.
Sensor yekugogodza inowanzoiswa panzvimbo chaiyo mubhokisi reinjini, senge pakati pemasilinda maviri nematatu emuchina une masilinda mana kana pakati pemasilinda rimwe ne maviri nesirinda rimwe kana mana. Nzvimbo yayo yekumisikidza inoita kuti injini ikwanise kubatwa nekunzwa kutetepa kwemhepo nekugogodza kudiki.
Kana sensor yekugogodza ikakundikana, kunyange zvazvo isingazokonzere kuti injini itadze kutanga, inokonzera matambudziko akadai sekumhanya kweinjini, kurasikirwa nesimba, kudzikira kwemafuta, uye mwenje yemafault. Saka, kushanda zvakanaka kwe sensor yekugogodza kwakakosha pakushanda kweinjini.
Automotive knock sensor mudziyo wakaiswa pa engine block, unoshandiswa zvakanyanya kuona kugogodza kweinjini. Kune mhando dzakawanda dze knock sensors, dzakajairika dzinosanganisira magnetostrictive uye piezoelectric ceramic.
Rudzi uye chimiro che sensor yekugogodza
Magnetostrictive : ine magnetic core, permanent magnet uye induction coil. Kana injini ikadedera, magnetic core inoshanduka, zvichikonzera shanduko mumagnetic flux mu induction coil, zvichikonzera induced electromotive force .
piezoelectric ceramic: Kana injini ikazununguka, ceramic iri mukati inodzvanywa kuti ibudise chiratidzo chemagetsi. Nekuti chiratidzo hachina kusimba, tambo yekubatanidza inowanzo kuputirwa newaya yakadzivirirwa .
piezoelectric resonance: yakaiswa pamusoro pemuviri weinjini, kushandiswa kwepiezoelectric effect kushandura mechanical vibration kuita masaini emagetsi. Kana knock vibration frequency ichiwirirana neyakajairika ye sensor, resonance phenomenon inoitika, uye high knock signal voltage ichaburitswa kuECU, zvichienderana nekuti ECU ichagadzirisa nguva yekupisa kuti isagogodza.
Mashandiro anoita sensor yekugogodza
Sensor yekugogodza inonzwa kudedera nemanzwi einjini uye inoashandura kuita masaini emagetsi anotumirwa kuyuniti yekudzora injini (ECU). ECU inogadzirisa Angle yekupisa zvichienderana nechiratidzo chakagamuchirwa kudzivirira kuitika kwekuputika. Nheyo chaiyo yekushanda ndeiyi inotevera:
Kudengenyeka kwesimba remagetsi: kudedera kweinjini kunoita kuti musimboti wemagineti uchinje, zvichichinja flux yemagineti mu induction coil, zvichikonzera simba remagetsi rinokonzereswa.
piezoelectric ceramic: kana injini yazununguka, piezoelectric ceramic inodzvanywa kuti ibudise chiratidzo chemagetsi, ECU inogadzirisa nguva yekupisa zvichienderana nechiratidzo.
piezoelectric resonance : kana frequency yekugogodza ichienderana nefrequency yechisikigo ye sensor, chiitiko che resonance chinoitika, uye voltage yechiratidzo chekugogodza yakakwira inoburitswa kuECU.
Basa rema sensor ekugogodza mumotokari
Basa guru reknock sensor nderekuyera jitter degree yeinjini. Kana injini yaburitsa knock, chiratidzo chemagetsi chinotumirwa kuECU, uye ECU inogadzirisa ignition advance Angle zvinoenderana nekudzivirira kugogodza kumwe. Knock inogona kukonzera kukuvara kweinjini, saka knock sensors inoita basa rakakosha mukudzivirira injini.
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonerei kana muchida zvigadzirwa zvakadaro.
