EGR valve - iyo EGR solenoid valve inoshanda sei uye ndeyei? Nzira yekubvisa sei kusashanda kwayo?

Kuderedza kuburitswa kwezvinhu zvinokuvadza zvinopisa kubva mukupiswa kwemafuta pane imwe nguva kwakava chiyero chakakosha muindasitiri yemotokari. Midziyo yakawanda uye masisitimu anoshandiswa pane izvi, akadai se:

• HORN;
• catalyst;
• particulate sefa;
• AdBlue.

Zvimwe zvikamu zveinjini uye zvishongedzo zvayo zvinowanzokanganisa kushanda kwayo, uye kana zvikashanda nemazvo, hazvionekwe. Panguva yekutadza kushanda, zvinova zvakanyanya kuoma, izvo zvinoita kuti hupenyu huome kune vatyairi vazhinji. Yakakuvadzwa EGR valve inokonzera zviratidzo zvakafanana neyakakundikana turbocharger.. Saka, sei kunyatsoongorora dambudziko mune injini ine EGR valve?

EGR vharafu mumotokari - chii uye chii chaizvo?

Iyo EGR system ine basa rekupinda zvakare mumagasi emhepo anokonzerwa nekupisa kwemafuta muhumburumbira. Paakabvunzwa kuti nei EGR valve ichidiwa, mhinduro iri nyore ndeyokuti yakagadzirirwa kuderedza kuwanda kwekukuvadza kwenitrogen-toxic compounds (NOx). Izvi zvinokonzerwa nekuderera kwekushisa mukati mekamuri rinopisa. Kutungamidza magasi ekubuditsa kudzokera kunjini uye kudzikisa kupisa kwekupisa kunoderedza mwero wemafuta oxidation process. Iyo EGR sisitimu yakagadzirirwa kugadzira zvakanyanya kuoma mamiriro ekubatanidzwa kweokisijeni nenitrogen, iyo inozoita kuderedza huwandu hwemagasi anokuvadza..

EGR kushanda muinjini

Iyo EGR solenoid valve haisi mudziyo wakasiyana, asi sisitimu ine chekuita nekupedza gasi recirculation.. Zvisinei, kazhinji inosanganiswa neEGR valve, iyo inokonzera matambudziko akawanda. Inowanikwa pakati pekutora uye exhaust manifolds. Kunyanya mumajini makuru epeturu uye mota dzine mayunitsi edhiziri, ine kuwedzera kutonhora. Izvi zvinodikanwa nekuda kwemagasi ekupisa anopisa kwazvo anosiya mukamuri yekupisa uye kukosha kwekudzoreredza huwandu hukuru hwadzo kudzokera mairi.

Kushanda kweEGR system kwakamanikana nekuti EGR valve pachayo haigare yakavhurika. Pasi pesimba rechiratidzo chakagamuchirwa kubva kune injini controller, iyo EGR inovhura, inodzora mushe kuyerera kwemagasi ekupedza. Iyi nzira inoitika chete paavhareji mutoro weinjini, nekuti jekiseni rekuburitsa gasi mukamuri rinopisa rinoderedza huwandu hweokisijeni, uye nekudaro inoderedza kushanda kwechikamu. EGR mumotokari haishande isingaiti, mudiki rev rev uye pamutoro mukuru.

EGR valve - sei kutarisa kana inoshanda?

Izvo zvinodikanwa kubatanidza diagnostic system kuti uone kuti EGR valve iri kushanda.. Kana iwe usingakwanise kuiwana, unogona kungoenda kuchitoro chiri pedyo chekugadzirisa auto. Rangarira, zvisinei, kuti mutengo wekuongororwa kwakadaro ungangoita makumi akati wandei ezł, zvichienderana nemhando yemotokari.

Zviratidzo zvekukuvara kweEGR valve

Zviratidzo zveEGR yakakuvadzwa zvakanyanya uye zvinoonekwa. Kusashanda zvakanaka kweEGR kunokonzera:

• kuwanda kwehutsi hutema kupfuura dhiziri;
• kamwe-kamwe kana zvachose kurasikirwa kwesimba;
• zvitoro zvemotokari zvisina basa. 

Mumamiriro ezvinhu akadaro, zvinowanzodiwa kuchenesa EGR.. Sechisarudzo chekupedzisira, EGR valve inoda kutsiviwa.

Nzira yekuchenesa sei EGR valve?

Iwe haufanirwe kuenda kuna makanika kuti uchenese EGR valve. Kana iwe uine zvishoma ruzivo rwemotokari uye mashoma makiyi, unogona kubudirira kuzviita iwe pachako. Kugadzirisa hazvidiwi kune pneumatically actuated versions, zvisinei, zvinogona kudiwa kune mamwe mazuva ano anodzorwa nemagetsi mavharuvhu, zvisingabatanidzi kugadzirisa pachako kunoshanda.

Chii chaunoda kuchenesa EGR valve iwe pachako? 

Chokutanga pane zvose, mumiririri wekuchenesa (somuenzaniso, peturu yekuwedzera kana nitro thinner), bhurashi, wrenches yekusunungura valve (kazhinji hex) uye gaskets. Sezvatataura pamusoro apa, tsvaga ichi chishandiso pakati pemanifold ekunze uye yakawanda yekudyara. Mushure mokusunungura nekuibvisa, zvakakosha zvikuru kuchenesa chete chikamu chinokonzera kufambisa valve, uye kwete zvinhu zvepneumatic uye diaphragm. Izvo zvakagadzirwa nerabha uye zvinogona kukuvadzwa nemvura ine hukasha.

Usashamisika kana mushure mekudisassembly ukaona soot yakawanda. Mhinduro yakanaka ndeyekugadzirira kwete yakakura, asi yakadzika mudziyo, iyo iyo EGR valve inonyudzwa uye inosiiwa kwemaawa akawanda kana zuva. Nenzira iyi iyo dema goo ichanyungudika uye iwe unogona kuchenesa ese ma nooks uye crannies nebhurashi. Mushure mekunge basa raitwa, iva nechokwadi chekupa EGR kupukuta kwakanaka usati waiisa mumotokari.. Iva nehanya nemagaskets matsva.

Nzira yekuchenesa EGR pasina disassembly?

Zvigadzirwa zviripo pamusika zvinobvumidza kubviswa kwekabhoni deposits uye zvimwe zvinosvibisa pasina kubvisa zvinhu. Zvechokwadi, pachava nenhamba huru yevatsigiri uye vanopikisa chisarudzo chakadaro, uye mumwe nomumwe wavo achave akarurama zvishoma. Kugadzirira nenzira yepfapfaidzo kunoshandiswa kune chirongwa chekutora panzvimbo, zvichienderana nekudiwa kwekuchenesa imwe chikamu. Kushandisa kunoitwa pane inomhanya uye inodziya injini zvinoenderana nemirairo yemugadziri wechigadzirwa. Dzimwe nguva, panzvimbo yekuchenesa, zvinogona kuitika kune mumwe munhu kuti avhare EGR valve. Zvinosanganisira chii?

Jamming EGR - mhedzisiro. Kugadziriswa kunodiwa riini?

Kune vamwe vatyairi, jamming iyo EGR inongova nemhedzisiro yakanaka - hutsi hushoma, hapana matambudziko nekuchinja kwemagetsi injini uye kubviswa kwejerks. Zvisinei, haisi kungotyaira chete, nokuti iyi hurongwa hwakabatana nehutano hwemagasi ekupedza. EGR inoderedza kubudiswa kwezvinhu zvine chepfu, saka zvakakosha kutevedzera mirairo. Mune dzimwe motokari dzemazuva ano, iyo, kunze kwevhavha pachayo, inewo nzvimbo ye sensor uye kutarisa chiyero chekusimudzira, kuisa plug muvharuvhu kuchakanganisa kushanda kwegungano. Mumamiriro ezvinhu akadaro, maitiro anofanirwa kuitwa neane ruzivo makanika anoziva zvemagetsi.

Ndeipi mhedzisiro yekuvharisa iyo EGR? Chaizvoizvo vane chekuita nekuongorora kwehunyanzvi. Kana iyo diagnostician, painoongorora mota, inoona kutyorwa kwakabatana nekuvhiya (kunyanya, kushaikwa kwekushanda) kweiyo epoust gasi recirculation valve, haazosimudze kuongorora. Pamusoro pezvo, kutadza kutevedzera mitemo yekuburitsa tsvina kunorangwawo nemapurisa. Mumotokari dzakavakwa kuti dzikwane, muridzi anogona kutarisira faindi ye5 PLN.

EGR shutdown kana EGR vharafu kutsiva?

Kana motokari yakakura uye motokari isina EGR sensor, kuvhara pavhavha yeEGR iri nyore. Uyezve, kutsiva EGR valve kunogona kudhura zvakanyanya. EGR solenoid inogona kudhura, sezvakaita basa. Zvose zvinogona kuva mazana zlotys. Panzvimbo yekubhadhara kutenga chikamu chitsva uye kutsiva EGR valve, vamwe vanosarudza kuisa.

EGR solenoid valve plug pane dizeli uye peturu nemhedzisiro

Mari yakakwirira yekutsiva EGR valve, chido chekudzivisa kudzokororwa zvakananga kumusoro mune ramangwana - izvi zvose zvinoita kuti vatyairi vakawanda vasarudze kuva bofu, i.e. dzima EGR. Zvine mhedzisiro here? Chii chinoitika kana iwe ukadzima EGR valve pane dhiziri kana peturu injini? Zvichida ... hapana. A side effect yekudzima EGR solenoid valve inogona kunge iri mwenje cheki injini. Mumotokari nyowani, mhedzisiro yekuremadza iyo EGR inogona kuderedzwa kuita kwekuita mune yepakati yekumhanyisa renji.

Kana iwe uchida kuti EGR system, kusanganisira EGR valve uye sensor, ishande zvisina kunaka kwenguva yakareba sezvinobvira, edza kuchenesa EGR solenoid valve nguva dzose.
