Accord 7 Knock Sensor

Iyo injini inogogodza sensor ndiyo imwe yeanonzwa mune injini manejimendi system. Pasinei nekuvimbika kwehukama hwekugogodza sensor paHonda Accord 7, dzimwe nguva inokundikana. Funga nezvechigadzirwa uye zvikonzero zvekusashanda kwe sensor, mhedzisiro inogoneka, nzira dzekudzora uye kutevedzana kwekutsiva sensor.

Knock sensor mudziyo Accord 7

Mota dzechinomwe Accord dzinoshandisa resonant type knock sensor. Kusiyana nebroadband sensor inoendesa iyo yese spectrum yeinjini vibrations kune control unit, resonant sensors inongopindura kune injini kumhanya kuri mukati me crankshaft kumhanya. Izvi zvine zvazvakanakira nezvazvakaipira.

Chinhu chakanaka ndechekuti injini yekudzora unit haifanire "kutarisira" maaramu enhema, semuenzaniso, kune yakakwira-frequency kuridza bhandi realternator, uye kumwe kudengenyeka kwekunze. Zvakare, resonant sensors ine yakakwirira amplitude yechiratidzo chemagetsi, izvo zvinoreva kukwirira kweruzha kusadzivirirwa.

Negative nguva - iyo sensor ine yakaderera senitivity pazasi, uye, zvinopesana, yakakwira injini kumhanya. Izvi zvinogona kukonzera kurasikirwa kweruzivo rwakakosha.

Kuonekwa kweiyo knock sensor Accord 7 inoratidzwa mumufananidzo:

Kuonekwa kwekugogodza sensor

Panguva yeinjini detonation, vibrations inopfuudzwa kune inozunguza ndiro, iyo, inonzwika, inodzokorodza kuwedzera ma mechanical vibrations. Iyo piezoelectric element inoshandura ma mechanical vibrations kuita mavibrations emagetsi anotevera injini yekudzora unit.

Sensor design

Chinangwa chekugogodza sensor

Chinangwa chikuru cheinjini kugogodza sensor ndechekugadzirisa kona yekupisa yeinjini kana injini inogogodza iripo. Injini kugogodza inowanzobatanidzwa nekutanga kutanga. Kutanga injini kutanga kunogoneka kana:

• kuwedzera mafuta nemafuta akaderera (somuenzaniso, nenhamba yakaderera octane);
• kupfeka kwemaitiro ekugovera gasi;
• kurongeka kwakashata kwekona yekudzima panguva yekudzivirira nekugadzirisa basa.

Kana chiratidzo chekugogodza chikaonekwa, injini yekudzora unit inogadzirisa mafuta, inoderedza nguva yekudzima, i.e. kunonoka kupisa, kudzivirira iyo detonation mhedzisiro. Kana iyo sensor isingashande nemazvo, detonation effect haigone kudzivirirwa. Izvi zvinogona kutungamirira kumigumisiro yakakomba, inoti:

• kuwedzera kukuru kwemutoro pane zvikamu uye maitiro ejini;
• kusashanda kwegasi rekugovera hurongwa;
• mamwe matambudziko akakomba kune kudiwa kwekugadzirisa injini.

Kukundikana kwekugogodza sensor kunogoneka nekuda kwezvikonzero zvinotevera:

• kupfeka;
• kukuvara kwemagetsi panguva yekugadzirisa basa kana pakaitika tsaona yemotokari.

Nzira dzekutarisa kusashanda kweiyo knock sensor

Chiratidzo chikuru cheyakaipa yekugogodza sensor kuvepo kweinjini inogogodza maitiro, iyo inonzwika kana iyo accelerator pedal inotsikirirwa zvakaomarara pasi pemutoro, senge kana uchityaira uchidzika kana kumhanyisa. Muchiitiko ichi, iva nechokwadi chekutarisa kushanda kwe sensor.

Nzira yakavimbika kwazvo yekuona kusashanda kweiyo Accord 7 injini kugogodza sensor ndeyekuitisa kuongororwa kwekombuta. Kodhi yekukanganisa P0325 inoenderana nekugogodza sensor kukanganisa. Iwe unogona zvakare kushandisa iyo parametric control nzira. Kuti uite izvi, sensor inofanira kubviswa. Izvo zvinodikanwawo kushandisa yakanyanya kujeka AC voltmeter (iwe unogona kushandisa multimeter seyekupedzisira sarudzo, kuseta switch kune yakaderera muganho kuyera AC voltage) kana oscilloscope kutarisa chiyero chechiratidzo pakati pekesi uye inobuda sensor. kugadzira mapundu madiki pachigadzirwa.

Iyo amplitude yezviratidzo inofanira kunge iine 0,5 volts. Kana iyo sensor yakanaka, unofanirwa kutarisa wiring kubva kwairi kuenda kune injini yekudzora unit.

Izvo hazvigoneke kutarisa sensor neine nyore dial toni ine multimeter.

Kutsiva iyo yekugogodza sensor neAccord 7

Iyo yekugogodza sensor inowanikwa munzvimbo isingaite yekutsiviwa: pasi peiyo manifold, kuruboshwe rwekutanga. Iwe unogona kuona nzvimbo yayo mune zvakadzama pane iyo dhizaini yekudhirowa.

Mumufananidzo uyu, sensor inoratidzwa munzvimbo 15.

Usati wabvisa iyo yekugogodza sensor, inofanirwa kubata iyo sensor yekumisikidza saiti neshizha simbi kana imwe yakakosha kuumbwa kuti ubvise coke, sezvo panguva yekushanda yaive mune mafuta kune yakanyanya tembiricha.

Iyo nyowani yekugogodza sensor haina kudhura. Semuenzaniso, yekutanga yeJapan-yakagadzirwa sensor pasi pechinyorwa 30530-PNA-003 inodhura anenge 1500 rubles.

Mushure mekuisa sensor nyowani, unofanirwa kusetazve injini zvikanganiso uchishandisa diagnostic scanner.
