EGR valve - chii uye ndinogona kuibvisa?

Iyo EGR valve chinhu chakasarudzika pasi pehodhi yemotokari iyo vatyairi vanowanzove nemanzwiro akavhengana nezvayo. Sei? Kune rumwe rutivi, ine basa rekugadzirisa huwandu hwemagasi emhepo uye zvinhu zvinokuvadza mukati maro, uye kune rumwe rutivi, chikamu chinowanzokundikana. Kazhinji, iyo itsva motokari, iyo yakakwirira mutengo wekugadzirisa kwayo ichava. Naizvozvo, vamwe vanhu vanosarudza kubvisa iyo EGR system mumotokari dzavo. Ichokwadi here?

Chii chauchadzidza kubva pane ino post?

• Chii chinonzi exhaust gasi recirculation valve?
• Sei kushanda?
• Kubvisa, kudzima, kupofumadza iyo EGR - nei zviito izvi zvisingakurudzirwe?

Kupfupi kutaura

EGR valve ine basa rekudzikisa huwandu hwemakemikari ane njodzi anoburitswa mumhepo pamwe chete nemagasi emhepo. Nekuda kweizvozvo, mota dzedu dzinoenderana neanowanzo gamuchirwa exhaust emission standard. Kana iyo EGR system ikakundikana, inofanira kucheneswa kana kutsiviwa nevhavha itsva. Nekudaro, hazvikurudzirwe kuibvisa, kudzima kana kuipofumadza - ichi chiitiko chisingabvumirwe chinobatsira kushata kwemweya uye kusvibiswa kwakawanda kwezvakatipoteredza.

Chii chinonzi exhaust gasi recirculation valve?

EGR (Exhaust Gas Recirculation) chaizvoizvo zvinoreva Exhaust Gas Recirculation Valve. Yakaiswa pane injini inobuda yakawandauye rimwe remabasa ayo makuru ndere kucheneswa kwemagasi anopedza simba kubva kune ane carcinogenic makemikari emakemikari - mahydrocarboni CH, nitrogen oxides NOx uye kabhoni monoxide CO. Zviri mukati mezvinhu izvi zvinonyanya kuenderana nerudzi rwemhepo inopisa-mafuta musanganiswa mumakamuri einjini:

• kupisa musanganiswa wakapfuma (mafuta akawanda, oksijeni shoma) inowedzera kuwanda kwemahydrocarboni mumagasi ekupedza;
• Kupisa kwakaonda (yakakwira okisijeni, yakaderera mafuta) inowedzera kuwanda kwenitrogen oxides mukubuda.

Ivhavha yeEGR (EGR valve) imhinduro yekuwedzera kusvibiswa kwezvakatipoteredza uye kuora kwehutano hwemhepo, iyo isingagumiri kune zvakatipoteredza chete. Zvekunetsa zveMotokari, zvakare kuziva nezve njodzi, kwenguva yakati yakanangana nekupa zvazvino, pro-zvakatipoteredza mhinduro uye matekinoroji, izvo zvinozowana zvinoshanda mumotokari dzedu. Pakati pavo tinogona kuwana masisitimu akadai seanoshandura anoshandura, mafirita echikamu kana EGR vharafu. Iyo yekupedzisira, inopesana nechitendero chakakurumbira, haina kukuvadza chikwata chekutyaira, ndiko kuti, haikanganisi kuita kwechokwadi kwemotokari.

EGR valve - nheyo yekushanda

Nheyo yekushanda kweEGR exhaust valve inonyanya kuenderana "Kuvhuvhuta" imwe chiyero chemhepo yekupedza gasi mujini. (kunyanya, mukamuri inopisa), iyo inoderedza kusunungurwa kwemakemikari anokuvadza. Kupisa kwekushisa kwepamusoro magasi anopinda zvakare mukamuri yekupisa mhanyisa evaporation yehuni uye gadzira zvirinani musanganiswa... Kudzokorora kunowanzoitika kana musanganiswa wemhepo-mafuta wakaonda, kureva kuti, iyo ine yakawanda yeokisijeni. Iyo flue gasi inobva yatsiva O2 (iyo iripo yakawandisa), iyo inoderedza kuwanda kweiyo yakambotaurwa nitrogen oxides. Izvo zvakare zvinokanganisa oxidation yeinonzi "Broken" hydrocarbon cheni.

Exhaust gasi recirculation masisitimu akakamurwa kuita maviri makuru marudzi - emukati nekunze:

• Internal exhaust gasi recirculation - inosanganisira kushandiswa kwekugadzirisa kwepamusoro muhurongwa hwekugadzirisa nguva, kusanganisira kuvharwa kwemavhavha emhepo kunononoka, uye panguva imwechete mavhavha ekupinda anovhurwa. Nokudaro, chikamu chemagasi ekupedza chinoramba chiri mukamuri rinopisa. Iyo yemukati system inoshandiswa mu-high-speed uye high-power units.
• External exhaust gasi recirculation - izvi zvimwe EGR. Iyo inodzorwa nekombuta, iyo zvakare ine mutoro kune akati wandei mamwe akakosha anoshanda paramita yemotokari yemotokari. Iyo yekupedza gasi recirculation valve inoshanda zvakanyanya kupfuura yemukati system.

EGR kupofumadza itsika inokurudzirwa here?

Iyo yekubuda gasi recirculation valve, pamwe nechero chikamu chinokonzera kuyerera kwemagasi, nekufamba kwenguva inosviba. Inoisa madhipoziti - madhipoziti emafuta asina kupiswa uye zvidimbu zvemafuta, izvo zvinoomesa pasi pesimba rekushisa kwepamusoro uye zvinogadzira yakaoma-ku-kubvisa crust. Iyi inzira isingadzivisiki. Naizvozvo, nguva nenguva tinofanira kuita kuchenesa kwakadzama kweiyo exhaust gasi recirculation valve, zviri nani kana paine matambudziko nebasa rayo risingashande - incl. yakawedzera kupisa, yakavharwa particulate sefa kana, muzviitiko zvakanyanyisa, kudzima injini.

EGR kuchenesa uye kutsiva

Iwo akatenderwa masevhisi masevhisi ane chekuita nekupera gasi recirculation vharafu ane chekuita nekugadzirisa kwayo (kuchenesa) kana kutsiviwa neitsva. Nekudaro, nekuda kwekusanzwisisa pamusoro pekukanganisa kwakaipa kweEGR pasimba reinjini, vamwe vatyairi nemakanika vakatsamira kune matatu anti-artistic tricks. Izvi:

• kubviswa kwekubuda kwegasi recirculation valve - inosanganisira kubviswa kweEGR system uye kutsiva iyo inonzi bypassiyo, kunyange zvazvo yakafanana mukugadzirwa, haibvumiri kupera gasi kupinda muhurongwa hwekudya;
• kupofumadza EGR - inosanganisira kuvharwa kwemagetsi kwekufamba kwayochii chinotadzisa hurongwa kushanda;
• magetsi deactivation ye exhaust gasi recirculation system - inosanganisira zvachose deactivation nemagetsi vharafu inodzorwa.

Izvi zviito zvakakurumbira zvakare nekuda kwemutengo wavo - vheji nyowani inogona kudhura anenge 1000 zlotys, uye nekupofumadza iyo yekubuda gasi recirculation system nekuichenesa, isu tichabhadhara anenge 200 zlotys. Pano, zvisinei, zvakakodzera kumbomira kwekanguva uye kufunga ndezvipi zvinokonzerwa nevhavhavha yeEGR yakavharwa.

Kutanga, ine ngwavaira inetapuro pamhoteredzo. Mota dzakadzimwa kana plugged exhaust gas recirculation valve zvakanyanya kudarika mwero unobvumidzwa wekupisa. Chechipiri, zvinoitika kuti kana vharuvhu yakavhurwa, iyo kukanganisa muhurongwa hwekutonga, zvichiita kuti kurasikirwa kwekutyaira kwekufambisa (Izvi ndezvechokwadi kunyanya kumakore matsva). Isu tinogona zvakare kuona Cheki Injini mwenje kana chiratidzo chinozivisa nezve kusarongeka mune exhaust gasi yekuchenesa system. Chechitatu, uye sezvakakosha, hapana chimwe chezviito zviri pamusoro (kubvisa, kusabatanidzwa, kupofumadza) zviri pamutemo. Kana kuongororwa kwemugwagwa kunoratidza kuti tiri kutyaira mota isina EGR system (kana ine plug) uye nekudaro tisingasangana nemiyero yekuburitsa, tinoisa njodzi. zvakanaka kusvika ku5000 PLN... Isu tine basa rekubvisa mota munzira.
