Oxygen sensor basic ruzivo uye kuona uye kugadzirisa, zvese kamwechete kukuudza!
Nhasi tichataura nezve ma sensors eokisijeni.
Kutanga, basa reokisijeni sensor
Iyo okisijeni sensor inonyanya kushandiswa kutarisa iyo okisijeni yemukati mumhepo yekuburitsa gasi reinjini mushure mekutsva, uye inoshandura iyo okisijeni yemukati kuita chiratidzo chemagetsi kuECU, iyo inoongorora uye kuona kusanganiswa kwemusanganiswa zvichienderana nechiratidzo, uye kugadzirisa. iyo nguva yejekiseni zvinoenderana nemamiriro ezvinhu, kuitira kuti injini iwane iyo yakanyanya kusanganiswa yemusanganiswa.
PS: Iyo pre-oxygen sensor inonyanya kushandiswa kuona kusangana kwemusanganiswa, uye iyo post-oxygen sensor inonyanya kushandiswa kuenzanisa chiratidzo chemagetsi neiyo pre-oxygen sensor yekutarisa shanduko yenzira nhatu inoshandura inoshandura. .
Chechipiri, kuisa nzvimbo
Oxygen sensors anowanzo kuuya ari maviri maviri, kune maviri kana mana, akaiswa mupombi yekupopotera matatu-nzira catalytic converter pamberi uye shure.
3. Chirungu chidimbu
Muchidimbu Chirungu: O2, O2S, HO2S
Chechina, kupatsanura chimiro
Kune nzira dzakawanda dzekuisa maokisijeni sensors, PS: ikozvino okisijeni sensors inopisa, uye yekutanga uye yechipiri mitsara isiri-inopisa oksijeni sensors. Uye zvakare, iyo okisijeni sensor inopatsanurwawo kumusoro (kumberi) okisijeni sensor uye yakadzika (kumashure) okisijeni sensor zvinoenderana nenzvimbo (kana basa). Mota dzakawanda dzave ne5-waya uye 6-waya Broadband oxygen sensors.
Pano, isu tinonyanya kutaura nezve matatu maokisijeni sensors:
Titanium oxide mhando:
Iyi sensor inoshandisa semiconductor zvinhu titanium dioxide, uye kukosha kwayo kwekudzivirira kunoenderana nekusangana kweokisijeni munzvimbo yakatenderedza semiconductor zvinhu titanium dioxide.
Kana paine okisijeni yakawanda kutenderedza, kuramba kwetitanium dioxide TiO2 kunowedzera. Kusiyana neizvi, kana okisijeni yakapoteredza iri diki, kushorwa kwetitanium dioxide TiO2 kunoderera, saka kushorwa kwetitanium dioxide okisijeni sensor inoshanduka zvakanyanya pedyo neiyo theoretical air-fuel ratio, uye kubuda kwemagetsi kunochinja zvakanyanya.
Ongorora: Kana tembiricha yadzikira zvakanyanya, kukosha kwekupokana kwetitanium dioxide kunoshanduka kuita infinity, zvekuti iyo sensor inobuda voltage ingangoita zero.
Zirconia mhando:
Nzvimbo dzemukati nekunze dze zirconia tubes dzakaputirwa nehupamhi hweplatinum. Pasi pemamwe mamiriro ezvinhu (kupisa kwepamusoro uye platinum catalysis), mutsauko unogona kuitika unogadzirwa nekusiyana kwehutano hweokisijeni kumativi ose e zirconia.
Broadband oxygen sensor:
Inonzi zvakare air-fuel ratio sensor, Broadband oxygen sensor, linear oxygen sensor, yakakura renji oxygen sensor, nezvimwe.
PS: Yakavakirwa pane inopisa zirconia mhando oxygen sensor yekuwedzera.
Zhuo Meng Shanghai Auto Co., Ltd. yakazvipira kutengesa MG&MAUXS zvikamu zvemotokari zvinogamuchirwa kutenga.
