Lambda probe - chii chinokonzeresa uye ndedzipi zviratidzo zvekukuvara kwayo?

Kune vese avo vanofunga kuti lambda probe chinhu chitsva chemidziyo yemotokari, isu tine nhau dzinosiririsa - makopi ekare eiyi zvishongedzo zvemotokari akaiswa anopfuura makore makumi mana apfuura. Kubva ipapo, kutarisisa kwekupedza gasi toxicity zviyero zvakawedzera zvakanyanya, saka dhizaini ye lambda probes uye nhamba yavo mumotokari zvachinja. Pakutanga zvakakodzera kutsanangura kuti lambda probe chii uye kuti inoshanda sei.

Chii chinonzi lambda probe uye inoshanda sei?

Nemashoko akareruka, lambda probe chinhu chidiki diki chinoti yeuchidza nezve spark plug. Waya yemagetsi yakabatana kwairi, iyo inotumira ruzivo nezvezvino kukosha kune dhiraivha controller. Iyo inoshanduka pasi pesimba rekuumbwa kwemagasi emhepo mumagetsi emagetsi. Kazhinji kazhinji inokwidziridzwa munzvimbo iri pakati peiyo manifold exhaust uye inoshandura inoshandura.

Chii chinonzi lambda probe? 

Sezvinoreva zita, ndezvekutarisa reshiyo yemhepo kune huwandu hwehuturu inobaiwa. Iri kushanda nemazvo lambda probe inokutendera kuti unyatso dhaya dosi yemafuta nekudzikisa kana kuwedzera nguva yejekiseni.

Chii chimwe chinokanganisa lambda probe?

Kuumbwa kwemhepo-mafuta musanganiswa kunokanganisa kushanda kwecatalytic converter. Inotarirwa neinonzi catalyst kutendeuka, i.e. mukana wekucheneswa kwayo kwemagasi ekupedza nekuita maitiro ekugadzirisa. Mumotokari dzisina kushandisa lambda probe, iyo catalyst inoshanda yakasvika 60%. Iye zvino michina iyi inopa ingangoita 95% kunyatsoshanda kwekusagadzikana kweanokuvadza makomisheni enitrogen kana kabhoni.

Nzira yekutarisa hutano hwe lambda probe?

Izvi zvinonyanya kuoneka muhuwandu hwehuni hwakatsva. Lambda inoshanda nemazvo inoshanda mumatatu matatu, ichitumira chiratidzo uchishandisa akasiyana voltages.

Kana kuumbwa kwemhepo-mafuta kusanganiswa kwakanyatsonaka, chigadziro chinobudisa chiratidzo che 1, icho chisingachinji kushanda kwemutongi maererano nejekiseni yemafuta. Zvisinei, munyaya yekuwedzera kwehuwandu hweokisijeni mumagasi emhepo (4-5%), magetsi anopiwa nechinhu chisati chapera. Mutongi "anoverenga" izvi sechido chekuwedzera huwandu hwemafuta akaiswa jekiseni nekuwedzera nguva yejekiseni yemafuta.

Panguva yekuderera kukuru kwehuwandu hweokisijeni mumagasi emhepo, lambda probe inowedzera simba, izvo zvinotungamirira kuderera kwehuwandu hwemafuta anopiwa. Exhaust composition inoratidza musanganiswa wakapfuma une mafuta akawandisa.

Zviratidzo zveakakuvadzwa lambda probe - ungazviziva sei?

Chiratidzo cheyakanganisika okisijeni sensor inowedzera kushandiswa kwemafuta, zvisinei nekutyaira maitiro. Muzviitiko zvakawanda, izvi zvinotowedzera zvakapetwa kaviri kupfuura mumamiriro ezvinhu akajairika. Ichi chiratidzo chakaoma kuona pasina kutarisa pa-bhodhi komputa. Mafupi madaro ekutyaira zvakare haabatsire kune izvi, nekuti haadyi yakawandisa mafuta.

Chimwe chiratidzo chekukuvadza kune lambda probe kusaenzana kweinjini kushanda. Panguva yekungoerekana yachinja nhanho dzekumhanya, unogona kufungidzira kuti lambda probe ichaongororwa nekukurumidza sezvinobvira. Iwe haugone kuita pasina kushanyira chiteshi chekuongorora.

Painjini dzedhiziri, utsi hutema hunobva kuchimuni huchawedzerawo, kunyanya kana huchikwira zvakasimba. Panguva dzakadai, mwero wehutsi ndiwo wakakwirira, saka zvinokwanisikawo kuona gore rinotyisa rehutsi.

Chiratidzo chekupedzisira chekusashanda kwe lambda probe kutaridzika kwe "cheki injini" mwenje pachiratidziro. Kunyangwe izvi zvichiwanzoreva zvikanganiso zvakawanda, kana iyo lambda probe ikakuvadzwa, yero icon ine zita reinjini chiratidzo.

Lambda probe - zviratidzo zveHBO

Zvizvarwa zvemhando II uye III gasi kuisirwa zvakashandisa zvakananga chiratidzo chinotumirwa ne lambda probes. Nekudaro, nekuuya kwechizvarwa chechiXNUMX chezvirimwa zvinoteedzana, mamiriro achinja. Iyo gasi controller inoshandisa zvakananga masensa ane basa rekushanda kwepeturu majekiseni, saka haatore zvakananga chiratidzo kubva kune lambda probe. Nekudaro, sezvamunoziva, komputa yeyuniti inoshandisa iyi chiratidzo kuona iyo chaiyo yemhepo-mafuta musanganiswa. 

Saka ndezvipi zviratidzo zveakakuvadzwa lambda probe mumotokari dzinofambiswa negasi? 

Chokutanga pane zvose, kupisa kunowedzera, asi kunhuhwirira kwegasi kunoonekwawo. Icho chikonzero ndechekutumira yakadzika yakadzika yakabuda voltage pamutengo wekunonoka sensor kukuvara uye komputa inowedzera metered mafuta. Izvi hazvinyanyi kukanganisa dhizaini yeinjini, asi zvinogona kutungamira mukuwedzera kushandiswa kwemafuta uye kusvibiswa kwemhepo.

Kutsiva yakakuvadzwa lambda probe

Sezvo maitiro ekushanda kweprobe akanyanyisa uye akaoma, nekufamba kwenguva inogona kukundikana. Naizvozvo, haufanirwe kuziva chete nzira yekutarisa lambda probe, asiwo nzira yekuitsiva uye kuti ndeupi modhi yekusarudza. Ichi chinhu chinogona kuwanikwa chakananga kumberi kweiyo catalytic converter uye iine plug iri mukati memugero wepakati kana kuseri kweiyo manifold ekutora. Mushure mekuwana, chinhu chinonyanya kukosha ndechekutenga kopi yakafanana (kana iyo yakakuvadzwa yakange yakanyorwa uye yemhando yepamusoro). Yakachipa inotsiva haipe iyo inodiwa paramita uye haina kusimba.

Iyo lambda probe chinhu chakakosha zvikuru chinobatanidzwa nekushanda kweinjini. Naizvozvo, kana uchitsiva lambda probe, gara uchisarudza modhi ine zviyero zvakafanana uye yakagadziridzwa kune chaiyo injini modhi. Usakanganwa kusarudza mabranded uye emhando yepamusoro zvikamu kuti urege kuomesa mashandiro emotokari neimwe inotsiva.
