Maitiro ekugadzira iwe-iwe-iwe pachako lambda probe snag

Ese mota dzemazuvano dzakashongedzerwa neuchi inopedza gasi toxicity neutralizer - inokonzeresa. Inodanwa kudaro pahwaro hwekuchinja kwemakemikari kunoitika ipapo, uko zvinhu zvakanakisa zvekuzadza zvinomhanyisa uye zvinoita kuti zvikwanise kugadzira zvinhu zvinokuvadza kuita izvo zvisina kwazvakarerekera nekukurumidza. Asi dzimwe nguva ichi chishandiso chinobatsira pachacho chinova chitubu chematambudziko makuru.

Sei uchinyengedza iyo oksijeni sensor

Iyo yakaonda chimiro cheiyo catalyst haimirire mechanical uye thermal overloads kwenguva yakareba. Tembiricha pano kunyangwe mune yakajairika mode inosvika chiuru madhigirii.

Ceramic honeycombs inoparadzwa, uye izvi zvinokonzera njodzi zviitiko:

• iyo yekuzadza inonyunguduka, siners uye inovharira kubuda kwemahara kwemagasi ekupedza;
• mizinga midiki yeuchi yakavharwa ne soot uye zvimwe zvigadzirwa zvine mugumisiro wakafanana;
• Chinhu chine njodzi ndechekuti iyo inokonzeresa, iyo vagadziri vanowanzoisa padyo sezvinobvira kune yekubuda chiteshi chemusoro we block kuti ikurumidze kudziya kusvika kune tembiricha yekushanda, inova sosi yeguruva re ceramic uye marara anopinda mumasilinda uye anoparadza injini zvikamu. .

Muinjini dzinonyanya kusavimbika pahwaro uhwu, varidzi vanowanzo bvisa ma converter ane njodzi kunyangwe aine mota yakaderera mileage. Nekuda kwekushandiswa kwesimbi dzakakosha mukuvaka, varidzi havadi kuisa zvinodhura zvepakutanga kana kugadzira zvigadzirwa.

Migumisiro inoratidzwa kwete chete mukuwedzera kwekupedza chepfu. Mamiriro ekugadzirisa anoramba achiongororwa nemagetsi ejini control unit (ECU) achishandisa zviratidzo kubva kune maviri okisijeni sensors (lambda probes).

Imwe yadzo iri pamberi peiyo catalyst, mota inodzora kuumbwa kwemusanganiswa wekushanda kuburikidza nayo, asi yechipiri inonyatso ikonzeresa yekubudirira kwekupedza neutralization.

Zviratidzo zvechipiri lambda zvinodzidzwa kuburikidza nekombuta, kusanganisira nekuita kudzora kutenderera kwekupisa iyo catalyst. Kusavapo kwayo kuchaverengerwa nekukurumidza, iyo sisitimu inoenda mune yekukurumidzira modhi uye nekusimbisa chiratidzo chekudzora pane dashboard. Injini icharasikirwa nehunhu hwayo hwese, kushandiswa kwemafuta uye mamwe matambudziko achatanga.

Kuti ushande pasina catalyst, unogona kushandura chirongwa che control unit. Chikamu chezvakatipoteredza chemotokari chichaenda pasi, asi kana zvisina kudaro ichava sarudzo yekushanda zvachose, zvinotokwanisika kuwedzera simba uye kuderedza kushandiswa, zvakatipoteredza hazviendi pasina, asi nokuda kwezvikonzero zvakasiyana-siyana, havasi vose vakagadzirira kuenda. nokuda kwayo.

Vamwe vanhu vanoda kunyengedza chirongwa cheECU chenguva dzose neimwe nzira, vachigadzira kuverenga kwakashata kweiyo okisijeni sensor.

Nheyo yekushanda kwe snag lambda probe

Mhedzisiro yakafanana inogona kuwanikwa nemagetsi uye mechanical nzira.

1. Muchiitiko chekutanga, chiratidzo chinogadzirwa icho, chokwadi, iyo okisijeni sensor haibudisi.
2. Mune yechipiri, mamiriro ese anogadzirwa kuti sensor ipe kuverenga kwakashata.

Haasi ese masisitimu anogona kunyengedzwa zvakavimbika nenzira dzechinyakare dzakadaro. Zvose zvinosarudzwa nemichina yeimwe motokari.

Mechanical musanganiswa we exhaust system catalyst

Nzira iri nyore ndeyekubvisa iyo okisijeni sensor kubva munzvimbo inodzorwa kweimwe chinhambwe nekuiisa pane spacer sleeve.

Chinhu chinoshanda chinotanga kushanda munzvimbo umo kuumbwa kwegasi kunoyerwa neimwe nzira, hukama hwakananga pakati pezviito zvekombuta uye mhinduro ye sensor inonyangarika, iyo inonzwisiswa nemapurogiramu akareruka sechiratidzo chezvakajairwa. kushanda kwecatalyst.

Blueprints

The spacer isimbi sleeve ine threaded magumo. Iyo tambo paramita inoenderana neyakaiswa sensor. Kune rumwe rutivi, shinda iri mukati, muviri we lambda probe inopindirwa mukati mayo, uye kune rumwe rutivi, iri kunze kwekuiswa mumucheka wakaiswa wepamhepo yekubuda kuseri kwecatalyst.

Gomba rinoboorwa pamwe chete neaxis yesleeve yekupfuura kwemagasi kune chinhu chinoshanda. Iyo paramita yebhushi ichave dhayamita yechiteshi ichi uye chinhambwe icho sensor inofamba kubva kune gasi ndima pombi. Izvo zvakakosha zvinosarudzwa kuyedza, iyo data inodiwa iri nyore kuwana kune chaiwo enjini mhando.

More advanced spacers ane catalyst elements. Muchiitiko ichi, iyo huru inoyerera inoenda yakananga kune yekubuda, uye iyo okisijeni sensor inogamuchira chete magasi akapfuura nepakati microcatalyst.

Chiratidzo chinozosiyana kubva kune chenguva dzose, asi mazhinji masisitimu anochigamuchira sechakajairika kushanda. Kunze kwezviitiko izvi apo ECU inoda kudziya iyo catalyst, uye kuiswa mu adapta hakuzoiti kune izvi nenzira ipi zvayo. Pamusoro pezvo, iyi microcatalyst inoita kukurumidza kuvharwa ne soot uye kumira kushanda zvachose.

Kuisa nzvimbo

Iyo catalyst inobviswa, uye spacer inoiswa panzvimbo yechipiri okisijeni sensor. Iyo dhayamita yegomba rekushanda inogona kusarudzwa maererano nekunyanya kugadzikana kushanda pasina kuratidza chiratidzo. Iyo sensor inopindirwa mushinda ye spacer. Ruzha rwekupopota runogadziriswa nekuisa chinosunga moto.

Electronic snag lambda probe

Nzira yemagetsi yekunyengedza ECU ndiyo yakarurama. Pane zvakawanda zvingasarudzwa pano, kubva kune yakapfava, apo iyo sensor chiratidzo inokwenenzverwa nesefa yakagadzirwa neanopikisa uye capacitor, hunhu hwayo hunosarudzirwa imwe komputa, uye kune mamwe akaomarara, ane jenareta inozvimiririra pulse.

The scheme

Simulation mune yakapusa kesi iri pasi peinobuda chiratidzo cheiyo oxygen sensor. Mune yepakutanga, ine nzvimbo dzakadzika, asi kana dzakazadzwa nerubatsiro rweRC cheni, saka mamwe mabhururu haazoone basa risingaite.

Zvimwe zvakaoma zvinokurumidza kuziva kunyengera panguva yekutanga kutonga kutenderera.

Kana iyo sensor ine yakashata yekupisa tambo, saka iwe unozofanirwa kuisa imwe resistor, sezvo bhuroka rinoziva kuzorora kwakadaro nekukurumidza uye nguva dzose.

Panzvimbo pe sensor, iwe unogona kubatanidza dunhu rinogadzira pulses, rakanyanya kufanana kune akajairwa. Kazhinji iyi sarudzo inoshanda, asi kana ECU yakadzidziswa kutenderera catalyst, zvino musanganiswa uyu hauzokwanisi kupindura zvakakwana.

Kuiswa nenzira

Izvo zvinodikanwa zveredhiyo zvikamu kana mabhodhi akaisirwa kungave mukuchekwa kweiyo oksijeni sensor chiratidzo waya kana panzvimbo payo, ichibatanidza zvakananga kune chinongedzo.

Gomba re sensor rinogona kuvharwa, semuenzaniso, nechikamu chakaremara.

Ndeipi yakanakisa lambda trick yekushandisa

Hapana akakwana cheats. Zvose zvinoenderana nemotokari chaiyo uye maitiro ekushandiswa kwebasa rekutarisa mamiriro ekugadzirisa. Muzviitiko zvakawanda, nzira chete yekubuda ndeyekuchinja ECU firmware.

Kazhinji izvi zvinotopiwa nepurogiramu yake, motokari dzakawanda dzinobudiswa mumhando dzakasiyana-siyana, kusanganisira dzisina catalysts. Chero zvazvingava, kudarika iyo yakavakirwa-mukati kutonga hakuzove kwakaoma kune ane ruzivo rwemota chiptuner.

Mibvunzo ine mutengo wevazhinji inomira uye kuvamanikidza kuita marudzi ese emanomano. Pano zvakakosha kunzwisisa zvakajeka kuti ndedzipi nzira dzinoshanda nemotokari iyi, uye ndedzipi dzichava kutambisa nguva nemari. Kunyangwe iwe uchigona kuyedza kana iwe uchikwanisa kutendeuka, zvikamu zveredhiyo uye simbi yekusimbisa.

Hazvigoneki kuti zvinokwanisika kukanganisa motokari pano, uye kana kukanganisa kwekupedzisira, zvisinei, taura nenyanzvi mukunyora purogiramu yekirasi yezvakatipoteredza.

Sechisarudzo, iwe unogona kuisa yakakwana yakasimba uye yakavimbika kugadzirisa catalyst, iyo, inopesana nemashure enguva yakashandiswa uye kubhadhara kwemabasa eshe, haitaridzi kudhura zvakanyanya.
