Musimboti:
Iyo oxygen sensor ndeye yakajairwa kumisikidzwa pamota.Inoshandisa ceramic inonzwa zvinhu kuyera kugona kweokisijeni mupombi yekupedza mota, uye inoverengera iyo inoenderana okisijeni kusungwa nekemikari chiyero chemisimboti yekutarisa uye kudzora kupisa kwemhepo-mafuta reshiyo kuti ive nechokwadi chechigadzirwa Uye chinhu chekuyera chinosangana nekubuda kwemhepo. standard.
Oxygen sensor inoshandiswa zvakanyanya mumhepo kutonga kwemarudzi akasiyana-siyana ekupisa kwemarasha, kupisa kwemafuta, kupisa gasi, nezvimwewo. Ndiyo nzira yakanakisisa yekupisa mamiriro ekuyera ikozvino.Iine zvakanakira chimiro chakareruka, kukurumidza kupindura, kugadzirisa nyore, kushandiswa kuri nyore, kuyerwa kwakaringana, etc. Kushandisa sensor kuyera uye kudzora mamiriro ekupisa hakugone chete kudzikamisa nekuvandudza mhando yechigadzirwa, asiwo kupfupisa kutenderera kwekugadzira uye kuchengetedza simba. .
Gadzirisa
Iyo oksijeni sensor inoshandisa iyoNernst musimboti.
The core element i porous ZrO2 ceramic chubhu, inova yakasimba electrolyte, ine porous platinum (Pt) maelectrodes akaiswa mativi ese.Pane imwe tembiricha, nekuda kwekuwanda kweokisijeni kwakasiyana mativi ese, mamorekuru eokisijeni ari kudivi rakakwirira-yakawanda (rutivi rwemukati rweceramic chubhu 4) anoiswa pamushonga weplatinamu uye anosanganiswa nemaerekitironi (4e) kuti aumbe. Oxygen ions O2-, iyo inoita kuti electrode iite zvakanaka, O2 -Ioni inotamira kune yakaderera oxygen concentration side (exhaust gas side) kuburikidza neoxygen ion vacancies mu electrolyte, kuitira kuti electrode inopomerwa zvakashata, kureva, inogona. musiyano unogadzirwa.
Kana iyo mhepo-mafuta reshiyo yakadzikira (yakapfuma musanganiswa), kune okisijeni shoma mumhepo yekuburitsa, saka kune mashoma maion okisijeni kunze kweceramic chubhu, kuumba simba re electromotive rinenge 1.0V;
Kana chiyero chemhepo-mafuta chakaenzana ne 14.7, simba re electromotive rinogadzirwa mukati uye kunze kwemativi e ceramic tube i 0.4V ~ 0.5V, uye iyi electromotive simba ndiro referensi electromotive simba;
Kana chiyero chemhepo-mafuta chakakwira (yakaonda musanganiswa), iyo okisijeni iri mugasi rekuburitsa yakakwira, uye iyo oksijeni ion concentration yemusiyano pakati pemukati nekunze kweceramic chubhu idiki, saka iyo inogadzirwa electromotive simba yakadzikira. pedyo ne zero.
Function
Basa re sensor ndeyekuona ruzivo rwekuti kune okisijeni yakawandisa mukubuda mushure mekupiswa kweinjini, kureva, iyo okisijeni yemukati, uye shandura iyo okisijeni yemukati kuita chiratidzo chemagetsi uye kuiendesa kune injini komputa, saka. kuti injini inogona kuona yakavharwa-loop control ine yakawandisa mhepo chinhu sechinangwa;to sure;Iyo mitatu-nzira inoshandura inoshandura ine hukuru hwekushandura hunoshanda kune zvitatu zvinosvibisa zvemahydrocarbons (HC), kabhoni monoxide (CO) uye nitrogen oxides (NOX) mugasi rekubuda, uye inowedzera shanduko uye kucheneswa kwezvinosvibisa zvinoburitsa.
Chinangwa
Oxygen sensors anoshandiswa zvakanyanya mumaindasitiri akadai se peturu, makemikari, marasha, simbi, kugadzira mapepa, kudzivirira moto, manejimendi manejimendi, mushonga, mota, uye gasi kubuda kwekutarisa.
YASEN inyanzvi yekugadzira bhizinesi mukugadzirwa kweVM okisijeni sensors, kana iwe uchida kuodha, gamuchira kuti utibate!
