EGR valve - ndeyei uye inogona kungobviswa?

Iyo EGR valve ndeimwe yezvishandiso izvo zvinokonzeresa kuderera kwemhepo, uye panguva imwechete imwe yeayo anokonzera matambudziko mazhinji. Kuparara kunoitika kakawanda, uye injini itsva, iyo inodhura zvikuru chikamu. Mari inoshandiswa i PLN 1000 kana kupfuura. Naizvozvo, vanhu vazhinji vanosarudza kubvisa kana kudzima EGR valve. 

Iyo EGR valve ndiyo chikamu cheEGR system iyo ine basa rekuvhura nekuvhara kuyerera kwemagasi emhepo kuburikidza nepombi yekubatanidza pakati peanopotera uye masystem ekupinza. Basa rake rakanangana naro kuderera kweokisijeni yemukati mumhepoiyo inodyiswa mumasilinda, nokudaro inoderedza kutonhora uye inoderedza kupisa kwemoto. Izvi, zvakare, zvinoderedza kuburitswa kwenitrogen oxides (NOx). Mumotokari dzemazuva ano, EGR valve inhengo inokosha yemidziyo yose yejini inobata zvakananga maitiro ekupisa. Pasina iyo, komputa yekudzora yaizonyimwa imwe yezvishandiso iyo inogona kuseta, semuenzaniso, tembiricha yakataurwa mucylinder.

Ivhavha yeEGR haideredzi simba ichiri kushanda.

Zvinowanzogamuchirwa kuti EGR valve ine basa rekudzikisa injini simba. Humbowo hweizvi - zvirinani mumadhizaini ekare - ndiyo mhinduro iri nani kukuwedzera kwegasi mushure mekubaya kana kubvisa EGR vharafu. Vamwe vanhu, zvisinei, vanovhiringidza zvinhu zviviri pano - simba guru nemanzwiro ekuzvibata.

Zvakanaka kuseka Injini inosvika pakureba kwayo kana iyo accelerator pedal yakatsikirirwa pasi - Throttle valve yakazaruka zvizere. Mumamiriro ezvinhu aya, EGR valve inoramba yakavharwa, i.e. haitenderi kupera magasi mumhepo inopinza. Saka hapana mubvunzo kuti izvi zvinokanganisa kuderedzwa kwesimba guru. Mamiriro acho akasiyana pakuremerwa kwechikamu, uko mamwe magasi ekupedza anopfuura nepakati peEGR system uye anodzokera kunjini. Zvisinei, saka isu tinogona kutaura kwete zvakanyanya pamusoro pekuderera kwesimba guru, asi pamusoro pekunzwa kusina kunaka, kunosanganisira kuderera kwekupindura kwekuwedzera kwegesi. Kuda kutsika gasi. Kuti ujekese mamiriro acho ezvinhu - kana EGR valve ichibviswa nenzira imwechete yekuzarura zvishoma, injini inogona kukurumidza kukurumidza.

Taura nezvazvo yakanyanya kuderedza simba tinogona chete kana EGR valve yakuvadzwa. Somugumisiro wekusvibiswa kwakanyanya, valve inomira kuvhara pane imwe nguva. Izvi zvinoreva kuti zvisinei kuti iyo throttle valve yakavhurika sei, mamwe emagasi ekupedza anopinda muhurongwa hwekutora. Uye ipapo, chaizvoizvo, injini inogona kusabudisa simba rakazara.

Sei EGR yakavharwa?

Kufanana nechikamu chega chega chine chekuita nekupihwa kwemagasi, iyo EGR valve inosvibawo nekufamba kwenguva. Danda rinoiswa ipapo, iro rinoomesa pasi pesimba rekushisa kwepamusoro, richigadzira yakaoma-ku-kubvisa crust. Uyezve, kana, semuenzaniso, kupisa kusingafambi zvakanaka kana mafuta einjini paanopisa, kuunganidzwa kwemari kunosvibisa vharuvhu nekukurumidza. Zvinongodzivisika, saizvozvowo Iyo yekupedza gasi recirculation valve chikamu chinoda kucheneswa nguva nenguva. Zvisinei, izvi zvinongoitwa chete kana matambudziko atanga kumuka.

Ipofumadze, bvisa, dzima

Mukuwedzera kune zvakajeka uye chete kugadzirisa kweEGR valve, i.e. kuchenesa kana - kana pasina chinoshanda - kuitsiva neitsva, vashandisi vemotokari uye makanika vanodzidzira zvitatu nzira dzisiri pamutemo uye dzisiri dzehunyanzvi dzekugadzirisa dambudziko.

• Batanidza EGR valve iyo inosanganisira mumagetsi kuvhara nzira yayo uye nokudaro kudzivirira zvachose kushanda kwegadziriro. Kazhinji, semugumisiro wekushanda kwema sensors akasiyana-siyana, injini ECU inoona kukanganisa, ichiisa chiratidzo cheCheck Engine.
• Kubvisa EGR valve uye kuitsiva iyo inonzi bypass, i.e. chinhu chakafanana mukugadzira, asi hachibvumiri magesi emhepo kuti apinde muhurongwa hwekudya.
• Electronic shutdown kubva pakushanda kweEGR valve. Izvi zvinogoneka chete nemavharuvhu anodzorwa nemagetsi.

Dzimwe nguva imwe yenzira mbiri dzekutanga inoshandiswa pamwe chete neyechitatu, nokuti injini yekudzora unit inogara ichicherechedza chiito chemagetsi pane EGR valve. Saka, mumainjini akawanda - mushure mekuvhara kana kubvisa EGR valve - iwe uchiri kufanira "kunyengera" mutongi. 

Ndeipi yeiyi nzira inopa mhedzisiro yakanaka? Kana tikataura pamusoro pemigumisiro nenzira yekushanda kwejini uye kusavapo kwezvinetso neEGR, saka munhu wose. Kunze kwekuti inoitwa nemazvo, i.e. shanduko mukutarisira injini inotariswa zvakare. Kusiyana nezvinoita kunge ndiyo chete inogoneka yakaringana EGR system kubva mukushanda kweinjini muhurongwa hwemagetsi, nekuti kupindira kwemagetsi hakukanganisi kushanda kweinjini komputa. Inoshanda uye inoshanda nemazvo chete mumotokari dzakura. 

Nhamo, kukanganisa EGR hazvisi pamutemonekuti zvinokonzeresa kuwedzera kwekubuda kwemhepo. Tiri kutaura pano chete nezvedzidziso uye mutemo, nekuti izvi hazvizogara zvichiva mhedzisiro. Iyo yakanyorwa patsva injini manejimendi chirongwa chinosanganisira kudzima EGR valve inogona kuunza zvirinani, kusanganisira yezvakatipoteredza, pane kuitsiva neitsva. 

Zvechokwadi, zvakanakisisa kutsiva EGR valve neimwe itsva pasina kupindira nekushanda kwejini zvachose. Kurangarira matambudziko awaive nawo, nguva nenguva - makumi ezviuru zvemamaira - unofanirwa kuichenesa isati yakakura yakaomeswa dhipoziti yaonekwa pairi zvakare.
