Kuongorora iyo catalyst ye back pressure

Kana mota yamira kukwira zvakajairwa kana kuti Cheki Injini mwenje ikauya, bvunzo yecatalytic converter inodiwa. Inogona kuvhara kana kuputsa zvachose muzinga weuchi. bobbin inogonawo kukuvara. Kuti utarise iyo catalyst, unogona kuibvisa zvachose kana kushandisa nzira yacho pasina kuibvisa. Kuoma kweiyi nzira iri mukuti iwe unoda mubatsiri kuti ashande neiyo yekumanikidza geji, haugone kurarama wega.

Zvikonzero zvekubvisa Catalyst

Pamatambudziko ekutanga mukushanda kwecatalyst, varidzi vemotokari dzakashandiswa vanofunga nezvekubvisa chinhu ichi. Panogona kuva nezvikonzero zvakawanda zveizvi.

Zvikonzero nei vazhinji vachibvisa catalysts:

vamwe vanokarakadza kuti catalyst ingakundikana panguva isina kufanira zvikurusa;
yechipiri inofunga kuti yakarohwa zvakanyanya nepeturu yemumba, haibvumire injini yekupisa mukati "kufema zvakanyanya";
vamwe vanotenda kuti kana iwe ukabvisa kupikisa kwakanyanya pakubuda, unogona kuwana kuwedzera kwesimba reICE, pamwe nekuderedza kushandiswa kwemafuta.

Asi, zvinosuruvarisa, vatyairi vazhinji vakakwira pasi pehodhi necrowbar vari mune isingafadze kushamisika - uye iyi iECU (ICE control unit). ichi chivharo chinoona kuti hapana shanduko mumagasi ekuburitsa pamberi uye mushure meiyo catalyst uye ichapa chikanganiso.

Zvinogoneka kunyengedza chivharo, asi iwe unogona zvakare kuivhenekera (iyi nzira haizotaurwa mune ino chinyorwa). Panyaya imwe neimwe, pane nzira (idzi nyaya dzinokurukurwa pamaforamu emashini).

Ngationei mudzi wezvakaipa - mamiriro e "katalik". ASI inofanira kubviswa? Vatyairi vakawanda vanotungamirirwa nemanzwiro avo: motokari yakatanga kudhonza zvisina kunaka, "Ndine chokwadi chokuti catalyst yakavharwa uye ndicho chikonzero," nezvimwewo. Ini handisi kuzonyengerera vakaoma musoro, asi vane njere vanoverenga. Saka, zvose zvaunoda kuita ndezvekutarisa mamiriro ekugadzirisa, uye zvichienderana nemamiriro ayo, tichagumisa kuti inoda kubviswa kana kuchinjwa, asi kazhinji inobviswa nekuda kwemari yavo.

Catalyst check

Kuongororwa kweiyo catalyst yekubvisa uye kuvhara

Saka, mubvunzo wakamuka, "Sei kutarisa catalyst?". Iyo inonyanya kushanda uye iri nyore nzira ndeyekubvisa iyo catalyst uye kuiongorora. Kana kukanganisa kwakanyanya kukawanikwa, iyo catalyst inogona kugadziriswa.

Isu tinobvisa catalyst uye tinotarisa mamiriro emasero sese - kuvharika kwemasero kunogona kuongororwa kuti kucheneswa, uye nekuda kweizvi chitubu chechiedza chinobatsira. Asi hazvisi zvese zviri nyore sezvazvinoratidzika. Dzimwe nguva, panguva yekushandiswa kwenguva refu, iyo catalyst gomo inonamatira zvakanyanya zvekuti Kubvisa iyo catalyst inogona kushanduka kuita basa refu uye rinonakidza. (Ini pachangu ndakasunungura nzungu mbiri dzekumashure kwemaawa matatu, pakupedzisira hazvina kushanda - ndaifanira kudzicheka nepakati!). Basa racho harina kunaka zvakanyanya, nekuti unofanirwa kushanda kubva pazasi mota.

Chiratidzo chikuru uye nzira dzekutarisa iyo catalyst haina kuvharika

kune kunewo nzira dzakawanda dzekutarisa iyo catalyst:

zvinokwanisika kuyera kupera kwezviri mukati mezvinhu zvinokuvadza (necho chinokanganisa chinokonzera, zvinyorwa zvezvinhu zvinokuvadza zvinowedzera zvakanyanya kana zvichienzaniswa ne-servable catalyst);
iwe unogona zvakare kutarisa kumanikidzwa kwemashure pakubuda (chiratidzo cheyakavharika catalyst inowedzera kushorwa uye, semhedzisiro, kumanikidza).

Kuti uone chinangwa chenyika, unofanirwa kusanganisa nzira mbiri idzi.

Kuongorora iyo catalyst ye back pressure

Back pressure test

Inotevera inotsanangura nzira yekutarisa mamiriro eiyo catalyst inopesana neyakagadzirwa back pressure.

Kuti uite izvi, pamberi peiyo catalyst, zvinodikanwa kuti weld sampling fittings yemuenzaniso wekupedza gasi. Zvinokurudzirwa kubatanidza mafittings neshinda uye chiteshi chimiro, izvi zvigadziriso zvakafanana nefittings for brake pombi. Mushure mekunge zviyero zvapedzwa, mapulagi anodzvanywa mune aya mafittings.

Stoppers kunyanya yakagadzirwa nendarira - izvi zvichavapa mahara unscrew panguva yekushanda. Nezviyero, pombi yebhureki 400-500 mm kureba inofanira kukwizwa mukati mekukodzera, iro basa nderekubvisa kupisa kwakanyanya. Isu tinoisa hose yerabha pamucheto wakasununguka wechubhu, hokore geji yekumanikidza kune hose, kuyerwa kwayo kunofanirwa kusvika 1 kg / cm3.

Izvo zvinodikanwa kuve nechokwadi kuti panguva iyi nzira hose haina kusangana nezvikamu zve exhaust system.

Kumashure kudzvinyirirwa kunogona kuyerwa uku mota iri kumhanyisa ne throttle yakavhurika. Kudzvanywa kunotarwa neiyo yekumanikidza geji panguva yekumhanyisa, nekuwedzera kwekumhanya, zvese zvakakosha zvinorekodhwa. Muchiitiko chekuti kukosha kwekumanikidzwa kwemashure panguva yekushanda ine damper yakazaruka yakazara mune chero nhanho yekumhanya inodarika 0,35 kg / cm3, izvi zvinoreva kuti iyo epoust system inoda kuvandudzwa.

Iyi nzira yekutarisa iyo catalyst inodiwa, zvisinei, muhupenyu chaihwo, welding fittings ibhizimusi rine madhaka. Naizvozvo, ndakaita izvi: Ndakasunungura lambda inomira pamberi pekatalyst ndokuisa chinoyera chekumanikidza kuburikidza neadapter. (Zvinokurudzirwa kushandisa geji yekumanikidza zvakanyanya kusvika 1 kg / cm3).

Se-adapter, ndakashandisa rubber hose, iyo yandakagadzirisa kuhukuru nebanga (usakanganwa kuti kusimba kunokosha).

Izvi ndizvo zvinoita basa rehunyanzvi chishandiso

Sam akamupima nehosi.

Saka:

Isu tinotanga injini yekupisa yemukati uye tinotarisa kuverenga kweiyo pressure gauge (iyi ndiyo backpressure pane yekubuda).
Isu tinoisa mubatsiri kumashure kwegumbo, anosimudza kasi kusvika ku3000, tinotora kuverenga.
Mubatsiri anosimudzazve kumhanya, asi atosvika ku5000, tinotora kuverenga.

ICE haidi kumonyaniswa! 5-7 seconds yakakwana. Izvo hazvifanirwe kushandisa yekumanikidza geji inoyera kusvika 3 kg / cm3, sezvo inogona kusatombonzwa kumanikidzwa. Iyo yakanyanya kudzvanywa geji ndeye 2kg/cm3, iri nani pane 0,5 (zvikasadaro kukanganisa kunogona kuenderana nehuyero kukosha). Ndakashandisa geji yekumanikidza iyo yakanga isina kunyatsokodzera, asi panguva imwechete iyo yakakwira yaive 0,5 kg / cm3, iyo yakakura panguva yekuwedzera kwekukurumidza kwekukurumidza kubva kuXX kusvika ku5000 (iyo geji yekumanikidza yakazununguka ikawira ku "0"). Saka, izvi hazvina basa.

Uye mupfungwa dzangu Nzira mbiri idzi dzinogona kusanganiswa seizvi:

1) kusunungura lambda pamberi pechinokonzera;

2) pachinzvimbo cheiyi lambda, isu tinokurisa mukukodzera;

3) sunga chimedu chepombi yebhureki kune yakakodzera (kune mabhaudhi emubatanidzwa);

4) isa hose pamagumo echubhu, uye uisundire mukati meimba;

5) zvakanaka, uyezve, sepakutanga;

Kune rimwe divi, isu tinobatanidza kune yekumanikidza geji, kuyerwa kwechiyero kunosvika 1 kg / cm3. Izvo zvinodikanwa kuve nechokwadi kuti iyo hose haina kusangana nemashoko eiyo exhaust system.

Kumashure kudzvinyirirwa kunogona kuyerwa uku mota iri kumhanyisa ne throttle yakavhurika.

Kudzvanywa kunotarwa neiyo yekumanikidza geji panguva yekumhanyisa, nekuwedzera kwekumhanya, zvese zvakakosha zvinorekodhwa. Muchiitiko chekuti kukosha kwekumanikidzwa kwemashure panguva yekushanda ine damper yakazaruka yakazara mune chero nhanho yekumhanya inodarika 0,35 kg / cm3, izvi zvinoreva kuti iyo epoust system inoda kuvandudzwa.

6) nekuda kwekusashanda (lambda isina kuvharwa, cheki inotanga kupisa), mushure mokunge lambda yaiswa panzvimbo, cheki ichabuda;

7) Muganho we 0,35 kg / cm3 unoshandiswa kumotokari dzakagadziriswa, asi kumotokari dzakajairika, mumaonero angu, kushivirira kunogona kuwedzerwa kusvika 0,5 kg / cm3.

Kana iyo diagnostics yecatalyst ikaratidza kuwedzera kupikisa kunopfuura kwemagasi emhepo, ipapo iyo catalyst inoda kunyungudutswa; kana kubhururuka kusingagoneke, ipapo iyo catalyst inofanirwa kutsiviwa. Uye kana kutsiva kusingagoneki mune zvehupfumi, saka tinobvisa iyo catalyst. Iwe unogona kudzidza zvakawanda nezve kuongorora backpressure catalyst muvhidhiyo pazasi:
