vatyairi Vazhinji vanodavira kuti EGR vharuvhu zvakafanira kudzima. Asi vamwe vanodavira kuti hazvina kukodzera kuti dzichikunetsa. Rega kunzwisisa kuti chii chinoumba mugadziriro.
recirculation (EGR) kazhinji anotadza uye anoita kusagadzikana mune injini kushanda panguva simbe. Mune zvimwe zviitiko, nokuda mhosva muchina anogona kungoti "kusimuka" panguva yomumugwagwa mwenje. Sezvingatarisirwa, hapana mufaro zvinetso zvakadaro havana kurwira. Uye kwete yose tenzi vanogona kukurira njodzi iyi. Vazhinji anoshandiswa "kurapa" kukanganisa mureza kana injini troit, jerks kana asingadi kutanga. Kuvadza USR - zvakaoma chaizvo kugadzirisa dambudziko kuti anogona anoedzesera kuva Misfire kana "nyengedza" zvemamiriro kubvisa mhepo. The Injini anogona anowanzoita kutanga akamuka uye kushanda zvakanaka, asi nokukurumidza ape chinoshamisa akatevedzana. Naizvozvo, nechirwere kukuvara negadziriro hakusi nyore. Hongu, uye kwete chitoro ose ane midziyo kuedza USR.
Chii USR?
Primordial basa rayo - kuchengetedza zvakatipoteredza. Part of chiutsi gasi inoendeswa sepombi mokugezera hurongwa, nokudaro achidzikisa combustion tembiricha uye, naizvozvovo, uwandu CO2. Asi zvose hachisi vakakwana, "achilles chitsitsinho" ino zvikuru ezvinhu - EGR vharafu. Vakawanda vanodavira kuti mashoko aya haasi kudiwa, asi akanga nguva aibvunzurudzwa "pfungwa" ari mumuchina uye zvazvinoita jekiseni hurongwa. Saka kana iwe nyore kudzima nechirwere kubudikidza zvakadzama ichi, tripcomputer anotambudza zvichemo zviri injini kudzora kukanganisa. Mukuwedzera, injini basa achapiwa kugadziridzwa kuratidza "mhosva", iyo ichaita kuti kuwedzera Diesel mafuta kuparadzwa, kurasikirwa simba uye zvimwe "nemazango". Asi pane nzira pano. Mune dzimwe motokari kuzvidzora kunoitika Via munhu solenoid vharafu uye EGR Vacuum kubva kurutivi yaunodya zhinji, uye mune mamwe - pachishandiswa tembiricha iri coolant Switch nezvimwe sensors.
vharafu kutadza zviratidzo
Kazhinji inoratidzwa sechipiriso jerk kana uchifamba yakaderera nokukurumidza. Anogona kurasikirwa simba uye inowedzera mutengo. Asi chakavimbika kupfuura chinoratidza - the runoenzanirana kukanganisa.
Sei uye nei unogona kudzima vharuvhu USR?
Pakutanga, chinangwa. Tsvikinyidza vharafu kuti chin'ai uye pedza gasi hazvirevi ichiyerera kunyika dura. Somugumisiro, mashoko sepombi kwenguva yakaisvonaka okisijeni iri mbuva, uye mafuta anopisa nani. Zhinji chisarudzo chinofanira vanyarare EGR vharuvhu pashure vanoverengeka ayo muchekechera. Kazhinji varwi kwezvakatipoteredza chete zvokuti kutarisa vaviri nguva kwete fuma zvokutadza zvinofadza kuomerera vharafu kuti kunzwisisa chii havadi nayo nendege kunyika yaunodya zvawanda.
Kuvhara vharuvhu EGR, pikicha kuti haasi zvinofadza meso, zvakakodzera sunungura screws uye awane ikanyanya. Uyezve, kubva Pepa simbi chekawo kwayo varara chimiro itsva gasket, ichazovapo maviri chete makomba bhaudhi. Zvino uise Mapedhi maviri panzvimbo. Unogonawo patsanura yacho Vacuum hosipaipi.
Vazhinji motokari varidzi vanoti kuti pashure zviito zvakadaro Turbo lag anonyangarika, zvichisiya utsi pasi rakaoma kumhanyisa, pamukwidza uye panguva dzakakwirira aimhanya Kuvandudzwa simba uye uwandu pfungwa.
