Lambda ine mazita akawanda...

Kuongorora huwandu hwemafuta emhepo uye nekugadzirisa huwandu hwemafuta akaiswa pahwaro uhwu ndiwo mabasa makuru e lambda probe, inogona kuwanikwa mumotokari nyowani uye mazhinji ayo akagadzirwa kubva 1980. Kwemakore makumi matatu nemashanu ekuvapo muindasitiri yemotokari, ese marudzi e lambda probes uye nhamba yavo mumotokari zvachinja. Mazuva ano, mukuwedzera kune gadziriso yechinyakare iri pamberi peinoshandura inoshandura, mota nyowani dzakashongedzerwa neinonzi diagnostic inogona kuwanikwa mushure meiyo catalytic converter.

Sei kushanda?

Iyo lambda probe inoshanda nezvinhu zvitatu zvikuru: jekiseni remafuta ejekiseni, yemagetsi control unit uye catalytic converter. Basa rayo nderekugadzirisa huwandu hwemafuta akaiswa jekiseni nekugara achiongorora chiyero chekutora mweya (okisijeni) uye mafuta. Zvichitaurwa zviri nyore, kuumbwa kwemusanganiswa kunofungidzirwa zvichienderana nehuwandu hweokisijeni. Kana musanganiswa wakanyanya kupfuma ukaonekwa, huwandu hwemafuta hunoiswa hushoma. Zvakapesana ndezvechokwadi kana musanganiswa wanyanya kuonda. Nokudaro, kuvonga kune lambda probe, zvinokwanisika kuwana chiyero chepamusoro chemhepo-mafuta, izvo zvisingakanganisi nzira yakarurama yekupisa, asiwo inoderedza kuwanda kwezvinhu zvinokuvadza mumagasi emhepo, kusanganisira, semuenzaniso. carbon monoxide, nitrogen oxides kana mahydrocarbon asina kupiswa.

Imwe kana maviri?

Sezvataurwa munhanganyaya iyi, mumotokari zhinji itsva unogona kuwana kwete imwe chete, asi maviri lambda probes. Yekutanga yavo, iyo inodzora, inzwa inobatsira kudzora kurongeka kwakaringana kwemafuta-mhepo musanganiswa. Chechipiri ndechekuongorora, kutarisa kushanda kwechigadzirisi pachayo, kuyera chiyero cheokisijeni mumagasi ekubuda achisiya catalyst. Iyi probe, kana inoona kuti mamwe magasi anokuvadza haasi kutora chikamu mumakemikari anoita neokisijeni, inotumira chiratidzo pamusoro pekukundikana kana kupera kwechinokonzera. Iyo yekupedzisira inoda kutsiviwa.

Linear zirconia kana titanium?

Lambda probes inosiyana pakuyera kwaanoita huwandu hwemhepo (okisijeni), uye nekudaro inogadzira masaini akasiyana ekubuda. Iyo inonyanya kuzivikanwa ndeye zirconium gauges, iyo zvakare isinganyanyi kurongeka kana zvasvika pakudzora mafuta akaiswa jekiseni. Kushata uku hakushandi kune vanonzi. linear probes (inozivikanwawo seA / F). Izvo zvakanyanya kunzwisisika uye zvinobudirira zvichienzaniswa ne zirconium, iyo inobvumira kunyatso kudzora huwandu hwemafuta jekiseni. Mhando inonyanya kushanda ye lambda probes titanium analogues. Ivo vanosiyana kubva pamusoro apa probes kunyanya nenzira yavanoburitsa chiratidzo chekubuda - izvi hazviitwe nemagetsi, asi nekushandura kushorwa kweprobe. Pamusoro pezvo, kusiyana ne zirconium uye mutsara probes, titanium probes haidi kusangana nemhepo yemuchadenga kuti ishande.

Chii chinoputika uye nguva yekuchinja?

Kushanda uye hupenyu hwesevhisi ye lambda probes inokanganiswa zvakananga nehusina kunaka hwemafuta kana kusvibiswa. Iyo yekupedzisira inogona kukonzera, kunyanya, kuburitswa kwemhepo inokuvadza, iyo inogona kuvhara iyo probe electrodes. Zvinoitika kuti marudzi akasiyana-siyana ezvinowedzera kumafuta einjini, mafuta kana zvinhu zvinoshandiswa kuvhara injini zvakare zvine njodzi. Kukuvadzwa kana kupfeka kune lambda probe inogona kuonekwa zvisina kunanga. Kukanganisa kwayo kunoratidzwa mukusakwana kwekushanda kweinjini uye kunyanya kushandiswa kwemafuta. Kukuvadza kune lambda probe zvakare kunotungamira kune yakawedzera nhanho yekubuda kwezvinhu zvinokuvadza zviri mumagasi ekupedza. Nokudaro, kushanda kwakarurama kweprobe kunofanira kuongororwa - zvichida pane imwe neimwe yekuongorora kwemotokari yemotokari. Pakutsiva lambda probe, tinogona kushandisa izvo zvinonzi zvakakosha zvigadzirwa, i.e. zvakachinjirwa kune zvakatemwa zverudzi rwemotokari uye zvakagadzirira kuisirwa nekukurumidza neplug. Iwe unogonawo kusarudza universal probes, i.e. pasina forogo. Iyi mhinduro inowanzova nyore, sezvo ichikubvumira kuti ushandise zvakare plug kubva kune yakasakara (yakaputsika) lambda probe.
