Catalyst - kapangidwe ndi ntchito. Kodi chida chothandizira ndi chiyani?

Kodi chothandizira ndi chiyani ndipo chifukwa chiyani chili chofunikira?

Mfundo imeneyi ntchito monga mbali ya dongosolo utsi ili mu chitoliro utsi. Chosinthira chothandizira chagalimoto chimafanana ndi chitoliro chokhala ndi mainchesi akulu kuposa gawo la utsi, lomwe limalumikizidwa ndi kuyika kwa zinthu zothandizira mmenemo. Mutha kuzizindikira mosavuta m'magalimoto azaka zakale, petulo ndi dizilo.

Mu zitsanzo zomwe zapangidwa panopa, chiwerengero cha otembenuza othandizira omwe amaikidwa m'galimoto imodzi chawonjezeka. Izi ndichifukwa chakuchulukirachulukira kwa miyezo yotulutsa utsi ndikuwononga zinthu zovulaza zomwe zimachokera ku tailpipe. Kukula kwaukadaulo kwakhudzanso kupanga zosefera zapadera zamagalimoto a dizilo, zomwe zimatchedwa DPF. Pakadali pano, pafupifupi magalimoto onse a dizilo pamsika ali ndi zosefera zotere.

Kapangidwe ka chothandizira ndi zochita zake

Kunja, chosinthira chothandizira chimafanana ndi silencer yotulutsa mpweya ndipo, malingana ndi galimotoyo, ikhoza kukhala ndi mawonekedwe osalala kapena a cylindrical. M'magalimoto amakono, amagwiritsidwa ntchito ngati chowonjezera chopopera. Ubwino wa njira iyi ndikuwotcha mwachangu komanso kugwira ntchito moyenera. Mkati mwa chipangizo chothandizira muli zigawo izi:

• chishango cha kutentha;
• zitsulo za ceramic kapena zitsulo;
• zisa za uchi.
  
  

Kodi chothandizira chimagwira bwanji?

Mukufuna kudziwa momwe chothandizira chimagwirira ntchito? Njira yonseyi imayamba pamene zinthu zoyaka zowopsa za osakaniza zimalowa mkati mwake. Izi ndi ma hydrocarbon, carbon monoxide ndi nitrogen oxides. Chifukwa cha mapangidwe ndi kukhalapo kwa platinamu, zinthu zina ndi ma oxides a alumina ndi cerium oxide, NOX imachotsedwa ndipo, chifukwa chake, nayitrogeni N imatulutsidwa mumlengalenga.₂. Mu gawo lina la chothandizira, CO imakhala ndi oxidized ndipo CO imapangidwa.₂ ndi h₂O.

Chothandizira m'galimoto - kukhazikika

Chosinthira chothandizira, ngakhale chikugwira ntchito mosalekeza komanso kukumana ndi kusintha kwa nyengo, ndi gawo losawonongeka komanso lokhalitsa. M'mikhalidwe yabwino, imatha kugwira ntchito bwino pamtunda wopitilira makilomita 200. Komabe, ndi ntchito ya galimoto, dzuwa ake amachepetsa, ndipo akhoza kuchulukitsidwa ndi kuwonongeka injini.

Car catalytic converter - zovuta

Kulephera kwa catalyst kumatha kukhala kwamakina ndipo kumaphatikizapo kuwonongeka kwa zolumikizira kapena casing. Chifukwa cha kugunda chopinga kapena chifukwa cha kuoneka kwadzidzidzi kwa madzi kuchokera pamadzi, chosinthira chothandizira m'galimoto chikhoza kulephera. Kuphatikiza apo, makina oyatsira olakwika amathanso kuyambitsa zosefera zamkati kulephera. Chifukwa chake nthawi zambiri chimakhala kumbali ya dongosolo loyatsira lolakwika.

Ngati mafuta sakuwotcha mu silinda, amalowa mu dongosolo la utsi ndi kuyatsa mu chosinthira chothandizira. Chodabwitsa ichi chimakweza kutentha mkati mwa chipangizocho ndikuwononga katiriji, kusokoneza khalidwe la kuyeretsedwa kwa gasi. Kuyesa kuyambitsa galimoto mu tow kapena "jolts" kumapereka zotsatira zofanana. Chotsatira chake, mlingo wosawotchedwa wa mafuta umalowanso mu dongosolo lotopetsa ndipo zotsatira zake zimakhala zofanana ndi zomwe zachitika kale.

Zizindikiro za chothandizira galimoto yowonongeka

M'magalimoto amakono, chosinthira chothandizira chosweka chimawonetsedwa ndi kuchepa kwa mphamvu. Chifukwa chiyani? Izi ndichifukwa choti sensa yomwe idapangidwa mu chosinthira chothandizira imalandira zinthu zosiyana ndi zomwe zimafakitale. Chidziwitsochi chimagwiritsidwa ntchito ndi woyang'anira kukonzekera kusakaniza kwa mafuta-mpweya wosakaniza, kotero kusokonezeka kulikonse kumayambitsa kusintha kwake ndipo, chifukwa chake, kuwonongeka kwa galimoto.

Mutha kuzindikira chosinthira chothandizira chomwe chawonongeka mgalimoto polemba pa dashboard. Nthawi zambiri ndiye kuwala lalanje kumayaka fufuzani injini. Inde, sikuti ili ndi udindo pa chipangizo chothandizira, kotero maonekedwe ake pawonetsero sizikutanthauza kuti chinthu chofotokozedwacho chawonongeka. Njira ina ndi kafukufuku wa organoleptic wa boma la chothandizira. Chinthu chosokonekera chimadzipangitsa kumva ndi kugogoda kwachitsulo ndikugwedezeka.

Momwe mungakonzere chosinthira chothandizira mugalimoto?

Imodzi mwa njira zazikulu ndi chothandizira kusinthika. Kutengera mtunduwo, izi zitha kukuwonongerani ndalama zoposa ma zloty chikwi. Komabe, akadali otsika mtengo kwambiri kuposa kugula chinthu chatsopano. Nthawi zina, chosinthira chothandizira sichingakonzedwe ndipo muyenera kusankha chinthu chatsopano. Mwamwayi, pali zambiri zolowa m'malo pamsika zomwe ndizotsika mtengo kwambiri kuposa zida zoyambirira. Amapezekanso ngati zigawo zapadziko lonse lapansi zofananira ndi mphamvu ya unit.

Zinthu zimakhala zovuta kwambiri pamene galimoto ili ndi otembenuza angapo othandizira, kuphatikizapo imodzi yomwe ili muzitsulo zotulutsa mpweya. Mtengo wake ukhoza kupitilira ma zlotys masauzande angapo, omwe amatha kutulutsa chikwama chanu. Ndikofunikira kuti mutatha disassembly, chosinthira chothandizira magalimoto chiyenera kutayidwa. Choncho, kukhazikitsa chipangizo chogwiritsidwa ntchito n'kuphwanya lamulo. Kuphatikiza apo, mphamvu yake nthawi zambiri imakhala yayikulu komanso yosadziwika.

Kapena mwina kudula ...

Monga momwe akatswiri amateur amanenera, "zimitsani chothandizira, pakhala mahatchi ambiri." Kumbali imodzi, izi ndi zoona, chifukwa chinthuchi chimachepetsa kutuluka kwa mpweya kwaulere. Kuchotsa kwake kumlingo wina kumawonjezera magwiridwe antchito agalimoto. Komabe, dziwani kuti galimoto yopanda chosinthira chothandizira sichigwirizana ndi homologation ya wopanga. Chotsatira chake, ndi diagnostician sangathe kusankha zotsatira zabwino pa mayesero. Kuonjezera apo, kukana galimoto ya chothandizira kumagwirizana ndi kusintha kwa kuwerenga kwa wolamulira injini. Monga mukuonera, chosinthira chothandizira chimagwira ntchito yofunika kwambiri m'galimoto, ndipo tikhoza kuyembekezera kusintha kwake m'zaka zikubwerazi. Ecology imakakamiza kugwiritsa ntchito njira zapamwamba kwambiri zoyeretsera gasi. Pogula galimoto yogwiritsidwa ntchito, muyenera kuyang'ana momwe galimotoyo imasinthira kuti mupewe kukonzanso kapena kusinthidwa.
