EGR vharafu rangarira Zvinofanira kutsiva?
Basa reEGR valve uye kukanganisa kwekukuvara.
Iyo EGR valve (Exhaust gas recirculation valve) chinhu chakakosha chekudzora cheinjini yemotokari, iyo inoiswa painjini kudzora huwandu hwekubuda gasi recirculation inodzoserwa muhurongwa hwekutora. Kana iyo EGR valve yakuvadzwa, inotungamira kumatambudziko akadai sekusagadzikana kusingaite kumhanya, kutadza kukurumidza, kuwedzera kushandiswa kwemafuta, uye kusakwana simba. Chikonzero chekuyeuka kazhinji ndechekuti zvikamu zvemukati zveEGR valve zvakasvibiswa nepamusoro-soro yeklorini mumafuta, zvichiita kuti pave nekushaya kushanda kwemuviri wevhavha, izvo zvinogona kukonzera injini kusashanda, uye mumamiriro ezvinhu akaoma, motokari inogona kumira. pakumhanya kwakaderera, zvichiwedzera njodzi yekuparara.
Zvikonzero uye kudikanwa kwekuyeuka
Chikonzero chekuyeuka kazhinji ndechekuti zvikamu zvemukati zveEGR valve zvakasvibiswa nepamusoro-soro yeklorini mumafuta, zvichiita kuti pave nekushaya kushanda kwemuviri wevhavha, izvo zvinogona kukonzera injini kusashanda, uye mumamiriro ezvinhu akaoma, motokari inogona kumira. pakumhanya kwakaderera, zvichiwedzera njodzi yekuparara. Nokudaro, kuchinjwa panguva yakakodzera kweEGR valve ndiyo chiyero chakakosha chekuvimbisa kushanda kwakajairika kweinjini uye kuchengetedzwa kwekutyaira.
Zvakanakira uye zvakaipira kutsiva EGR vharafu
Kutsiva EGR valve kunogona kuve nechokwadi chekushanda kwakajairika kweinjini, kudzivirira matambudziko akadai seasina kugadzikana kukurumidza kukurumidza uye kutadza kukurumidza, uye kuderedza kushandiswa kwemafuta uye simba risina kukwana. Zvisinei, kutsiva EGR valve kunoda imwe mari uye nguva, uye zvingave zvakakosha kana motokari yave ichishandiswa kwenguva yakareba kana kuti ine mileage yakawanda; Zvisinei, kana motokari ichishandiswa kwenguva pfupi kana kuti ine mileage shoma, unogona kufunga kuenderera mberi nekushandisa zvikamu zvepakutanga kugadzirisa.
Chii chinonzi egr valve?
Exhaust gasi recirculation valve
EGR vharafu inopedza gasi recirculation valve. Icho chigadzirwa chemagetsi chekubatanidza chakaiswa painjini yedhiziri kuti idzore huwandu hwekuburitsa gasi recirculation yakadzoserwa kuhurongwa hwekutora, uye yakakosha uye yakakosha chikamu mune yekuburitsa gasi recirculation mudziyo. .
Basa guru reEGR valve ndere kudzora huwandu hwemhepo inopedza gasi inopinda muhuwandu hwekudya, kuitira kuti imwe huwandu hwemhepo inopera inoyerera ichipinda muhuwandu hwekutora kuti idzoke zvakare. Inowanzo kuwanikwa kudivi rerudyi rekupinza manifold, padhuze nemuviri wekufema, uye inosarudza huwandu hwegasi rekuburitsa rinoendeswa kune yakawanda yekutora nedhigirii rekuvhurwa kwevhavha inodzorwa neiyo vacuum chubhu. Nekutungamira gasi rekuburitsa kubva mumoto weinjini kuenda kune yakawanda yekutora kutora chikamu mukupisa, iyo EGR valve inogona kuderedza kupisa kwekamuri yekupisa, kuvandudza injini kushanda zvakanaka, kuvandudza nharaunda yekupisa, uye kuderedza mutoro weinjini. Panguva imwecheteyo, inogona kunyatso kudzikisa kubuda kwekabhoni monoxide makomisheni, kuderedza kugogodza, uye kuwedzera hupenyu hwebasa rechikamu chimwe nechimwe.
Mukuwedzera, mavharuvhu eEGR akakamurwawo kuva marudzi maviri emakanika uye emagetsi kutonga kuti aenderane nezvinodiwa zveinjini dzakasiyana. Muinjini yemazuva ano inodzorwa nemagetsi, kuitira kunyatso kudzora huwandu hwekuburitsa gasi kudzokororwa, iyo yakavharwa-loop yekudzora nzira inotorwa zvakare, uye phase sensor inoiswa paEGR valve kuti inzwe kushanda kweinjini muchokwadi. nguva, uye maererano nemashoko aya, EGR valve inogadziriswa kuti ivhure uye ivhare, kuitira kuti iwane kutonga kwakarurama kwehuwandu hwekupedza gasi recirculation.
Car egr valve yatsemuka ine chiratidzo chipi?
Ndezvipi zviratidzo zviri pachena zvaungave nazvo kana EGR valve yemotokari yako yakundikana?
EGR vharafu, iyo yekupedza gasi recirculation system valve, kana yakanganisa, mota ichaonekwa nhevedzano yezviratidzo zvekunyevera. Chekutanga, kusagadzikana kana kudzima moto chinhu chinowanzoitika, uye mwenje wemhosva unogona zvakare kupenya kazhinji kukuyeuchidza kuti uteerere mamiriro einjini. Chechipiri, nokuti EGR kukundikana kwevhavha kunogona kutungamirira kune kusvibiswa kwepasi, motokari inogona kutarisana nekunyadziswa kwekukundikana kupasa kuongororwa kwegore negore.
Kana EGR valve ichichengetwa yakazaruka, migumisiro inotonyanya kukosha: motokari icharatidza utsi hwakasviba uye kusava nekukurumidzira, asi kushandiswa kwemafuta kunoderera uye kushandiswa kwemafuta kunowedzera. Pane zvinopesana, kana EGR valve yakavharwa, kubuda kwemhepo kunokanganiswa uye kunogona kutungamirira zvakananga mukukundikana kupfuudza maitiro ekuongorora kwegore negore.
Kana zviri izvo zvinokonzeresa EGR kukuvadzwa kwevharuvhu, pane zvakanyanya akati wandei zvinhu: tsvina gasi recirculation system matambudziko emhando, kutadza kugadzirisa, kushata kwemafuta uye kuchembera kwevhavha pachayo. Semuenzaniso, kushandiswa kwepasi-kuchena peturu kana kuwedzera zvisina kufanira kwemafuta emafuta kunogona kuve kamwe kamwe chinhu chinokonzera EGR kukundikana kwevhavha. EGR mavharuvhu anoshanda pakudziya kweinjini yakakwira, uye nekufamba kwenguva, sevhavha yekamuri yevhavha yevhavha mapedhi uye mhete dzerabha, ivo vanokura nekuda kwekupfeka.
Pakazere, hutano hweEGR valve hwakakosha kuchengetedza kushanda kweinjini uye kuburitsa kwezvakatipoteredza, kana zviratidzo zviri pamusoro zvawanikwa, kuchengetedza kwehunyanzvi kunofanirwa kutsvakwa nekukurumidza sezvinobvira kuti ive nechokwadi chekuti kutyaira kuchengetedza uye zvinodiwa zvezvakatipoteredza zvinosangana.
Kana iwe uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonere kana uchida zvigadzirwa zvakadaro.
