musimboti wekushanda

1.Oxygen sensor ndiyo inogadziriswa inogadziriswa mumotokari. Icho chinhu chekuyeresa chinoshandisa ceramic inonzwa zvinhu kuyera kugona kweokisijeni mumapombi ekufambisa emotokari, uye inoverengera inoenderana neokisijeni inoenderana nemusimboti wemakemikari chiyero, kuitira kutarisa uye kudzora kupisa kwemhepo-mafuta chiyero uye kuona chigadzirwa. kunaka uye exhaust emission kuti isangane nezviyero. Oxygen sensor inoshandiswa zvakanyanya mumhepo kutonga kwekupisa kwemarasha kwakasiyana, kupisa kwemafuta, kupisa gasi uye mamwe mavira. Ndiyo nzira yakanakisa yekuyera mamiriro ekupisa panguva ino, uye ine zvakanakira chimiro chakareruka, kukurumidza kupindura, kugadzirisa kuri nyore, kushandiswa kuri nyore uye kuyerwa kwakaringana. Kushandisa iyi sensor kuyera uye kudzora kupisa kwemhepo hakugone chete kudzikamisa nekuvandudza mhando yechigadzirwa, asiwo kupfupisa kutenderera kwekugadzira uye kuchengetedza simba.

2.Nheyo yekushanda yeokisijeni sensor mumotokari yakafanana neyebheteri yakaoma, uye zirconia element mu sensor inoita se electrolyte. Nheyo yayo yekutanga yekushanda ndeye: pasi pemamwe mamiriro, mutsauko unogona kuburitswa nekushandisa iyo oxygen yekumisikidza musiyano pakati pemukati nekunze kwe zirconia, uye iyo yakakura iyo yekumisikidza musiyano, yakakura mutsauko unogona. Izvo zviri mukati meokisijeni mumhepo i21%, uye gasi rekuburitsa mushure mekupisa musanganiswa wakapfuma harina oxygen. Gasi rinobuda mushure mekupisa musanganiswa wakaonda kana gasi remhepo nekuda kwekushaikwa kwemoto rine okisijeni yakawanda, asi ichiri shoma pane iyo okisijeni iri mumhepo. Pasi pekugadzirisa kweplatinum pakupisa kwepamusoro, ion yeokisijeni yakashata inoshambadzirwa mukati nekunze kwekunze kwe zirconia sleeve. Nekuda kwekuti kune mweya weokisijeni wakawanda mumhepo kupfuura mumhepo inobuda mumhepo, rutivi rwuri kutaurirana nechadenga pane casing rinotora mamwe maioni asina kunaka kupfuura ari padivi pegasi rekubuda, uye musiyano weiyoni kumativi ese maviri unoburitsa simba remagetsi.

3.Apo iyo okisijeni inopinda padivi rekubuda gasi remotokari casing yakaderera, mhepo yakakwira (0.6 ~ 1V) inogadzirwa pakati pemagetsi eiyo okisijeni sensor, uye ichi chiratidzo chemagetsi chinotumirwa kumotokari ECU kuti iwedzere. Iyo ECU inoona iyo yakakwira voltage siginecha seyakapfuma musanganiswa uye yakaderera voltage chiratidzo seyakaonda musanganiswa. Maererano nemagetsi emagetsi emagetsi emagetsi emhepo, kombiyuta inoderedza kana kuwedzera musanganiswa maererano ne theoretical optimal air-fuel ratio sepedyo sezvinobvira kusvika 14.7: 1. Nokudaro, okisijeni sensor ndiyo sensor inokosha yemagetsi kutonga metering yemafuta. Chete kana iyo okisijeni sensor iri pakupisa kwakanyanya (kuguma kunosvika kupfuura 300 ° C) maitiro ayo anogona kuratidzwa zvizere uye voltage inogona kubuda. Panenge pa800 ° C, ine mhinduro inokurumidza kune shanduko yemusanganiswa, asi hunhu uhu huchachinja zvakanyanya pakudzika kwakadzika.
