Kutsiviwa kwerambi reNissan Qashqai probe

Lambda probe (DC) ndechimwe chezvinhu zvikuru zveiyo exhaust system yemotokari dzemazuva ano. Izvo zvinhu zvakaonekwa zvine chekuita nekugara kusimba kwezvinodiwa zvezvakatipoteredza, basa ravo nderekugadzirisa huwandu hweokisijeni mumagasi ekuburitsa, izvo zvinokutendera kuti uone kurongeka kwakaringana kwekusanganiswa kwemafuta emhepo uye kubvisa kuwedzera kwekushandisa peturu.

Lambda probes (kune maviri acho) anoshandiswa mumhando dzese dzeNissan Qashqai, kusanganisira zvizvarwa zvekutanga. Nehurombo, nekufamba kwenguva, sensor inogona kutadza. Kudzoreredza kwayo mhinduro isingashande; yakavimbika zvakanyanya kuita kutsiva kwakazara.

Yekutanga okisijeni sensor inowanikwa mune yakawanda yekudyara.

Kuputsika kukuru

Sensor defects inowanzo ratidzwa sezvinotevera:

• kuputsika kwechinhu chinopisa;

• kupisa kweceramic tip;

• kubata oxidation, kuumbwa kwekuora, kutyora kwekutanga kwemagetsi conductivity.

Kukundikana kweprobe kunogona kuve nekuda kwekupera kwehupenyu hwebasa. KuQashqai, kukosha uku kunosvika zviuru makumi manomwe zvemakiromita.

Mamiriro acho anodzorwa otomatiki neayo mota system.

Kuonekwa kwekusashanda kunobva kwakonzeresa activation yeiyo LED pane chiridzwa.

Izvo zvinofanirwa kuyeukwa kuti kutsauka mukushanda, zvisina kunanga zvichiratidza kusashanda kweiyo sensor, inogona zvakare kusanganiswa nemamwe ma module emafuta uye exhaust system. Zvichave zvichibvira kuziva chikonzero chaicho nerubatsiro rwekuongorora. Failure Definition

Izvi zvinotevera zvinoratidza kutadza kwesensor:

• kuwedzera kukuru mukushandiswa kwemafuta;

• kusagadzikana kwemotokari, nguva dzose "inoyerera" kumhanya;

• kukundikana kwekutanga kwechigadziriso nekuda kwekuvhara kwayo nezvigadzirwa zvinopisa;

• jolts kana motokari ichifamba;

• kushaya simba, kunonoka kukurumidza;

• nguva nenguva kumira kweinjini idling;

• mushure mekumira munzvimbo iyo lambda probe iripo, kurira kunonzwika;

• Kuongororwa kwekuona kwe sensor pakarepo mushure mekumira kunoratidza kuti yakatsvuka inopisa.

Zvinokonzera kuparara

Zvinoenderana nehuwandu hweNissan Qashqai sevhisi nzvimbo, zvinonyanya zvikonzero zvekutadza kwezvikamu ndezvi:

• Unhu husina kunaka hwemafuta, huwandu hwepamusoro hwekusvibiswa. Njodzi huru kune chigadzirwa ndiyo mutungamiri uye makemikari ayo.

• Kusangana kwemuviri neantifreeze kana brake fluid kunokonzera oxidation yakakura, kushanduka kwetembiricha, kukuvadzwa kwepamusoro uye kwechimiro.

• Kuedza kuzvichenura uchishandisa makomisheni asina kukodzera.

Kuchenesa

Vazhinji varidzi veNissan Qashqai vanosarudza kuchenesa sensor pane kuitsiva nechikamu chitsva. Kazhinji, nzira iyi inoruramiswa kana chikonzero chekukundikana chiri kusvibiswa nezvigadzirwa zvinopisa.

Kana chikamu chacho chichiita sechinyakare kunze, hapana kukuvara kunooneka pairi, asi soot inoonekwa, saka kuchenesa kunofanira kubatsira.

Unogona kuibvisa sezvizvi:

• Chinhu chikuru chinoshandiswa iphosphoric acid, iyo inopedza zvakakwana carbon deposits uye ngura. Mechanical yekuchenesa nzira haigamuchirwi, sandpaper kana simbi brashi inogona kukuvadza zvachose chikamu.

• Nzira yekuchenesa pachayo inobva pakuchengeta sensor mu phosphoric acid kwemaminitsi 15-20 uye wozoomesa. Kana iyo nzira isina kubatsira, pane imwe chete nzira yekubuda - yekutsiva.

Replacement

Kuchinja lambda probe yeNissan Qashqai iri nyore, sezvo chikamu chiri mune exhaust manifold uye izvi zvinoita kuti zvive nyore kuwana.

Usati watsiva, zvakakosha kuti udziye chigadziko chemagetsi zvakanaka, kuwedzera kwekupisa kwesimbi kunoita kuti zvive nyore kubvisa chikamu kubva pane zvakawanda.

Mirayiridzo inoita seizvi:

• Vhara injini, dzima moto.

• Kubvisa tambo.

• Bvisa chikamu chakakundikana ne socket kana wrench, zvichienderana nerudzi rwe sensor.

• Kuiswa kwechimwe chinhu chitsva. Inofanirwa kukwizwa mukati kusvika yamira, asi pasina kudzvanyirira kwakanyanya, iyo yakazara nekukuvadzwa kwemichina.

• Kubatanidza tambo.

Sezvineiwo, isa yekutanga Nissan sensors. Asi, mukusavapo kwayo, kana kudiwa kwekukurumidzira kuchengetedza mari, unogona kushandisa analogues kubva kuGerman kambani Bosch.

Vakazviratidza zvakanaka nevaridzi veKashkaev, vanoshanda zvakakwana uye vane hupenyu hwebasa hwakafanana nehwepakutanga.
