Kudzoserwa kwevharuvhu yeEGR kunofanirwa kutsiva here?
Basa revharuvhu yeEGR uye kukanganisa kwekukuvara.
Vharuvhu yeEGR (vharuvhu yekudzokorora magasi emota) chinhu chakakosha chekudzora injini yemotokari, iyo inoiswa painjini kudzora huwandu hwegasi rekudzokorora magasi rinodzoserwa muhurongwa hwekudya. Kana vharuvhu yeEGR ikakuvara, zvinozokonzera matambudziko akadai sekumhanya kusina kugadzikana, kumhanya kusingashande zvakanaka, kushandiswa kwemafuta kwakawanda, uye simba risina kukwana. Chikonzero chekudzoserwa kwemotokari kazhinji ndechekuti zvikamu zvemukati zvevharuvhu yeEGR zvinokanganiswa nehuwandu hwakawanda hwechlorine mumafuta, zvichikonzera kusashanda zvakanaka kwemuviri wevharuvhu, izvo zvinogona kukonzera kusashanda zvakanaka kweinjini, uye mune zviitiko zvakanyanya, mota inogona kumira nekumhanya kwakaderera, zvichiwedzera njodzi yekudonha.
Zvikonzero uye kukosha kwekuyeuka
Chikonzero chekudzoserwa kwemotokari chinowanzo kuve chekuti zvikamu zvemukati zvevharuvhu reEGR zvinokanganiswa nekuwanda kwechlorine mumafuta, zvichikonzera kusashanda zvakanaka kwemuviri wevharuvhu, izvo zvinogona kukonzera kusashanda zvakanaka kweinjini, uye muzviitiko zvakanyanya, mota inogona kumira nekumhanya kwakaderera, zvichiwedzera njodzi yekudonha kwemotokari. Saka, kutsiva vharuvhu reEGR nenguva inzira yakakosha yekuona kushanda kwakajairika kweinjini uye kuchengetedzeka kwekutyaira.
Zvakanakira nezvakaipa zvekutsiva vharuvhu yeEGR
Kutsiva vharuvhu yeEGR kunogona kuve nechokwadi chekuti injini inofamba zvakanaka, kudzivirira matambudziko akadai sekumhanya kusina kugadzikana uye kumhanya kusingafadzi, uye kuderedza kushandiswa kwemafuta uye simba risina kukwana. Zvisinei, kutsiva vharuvhu yeEGR kunoda mari yakati wandei nenguva, uye kunogona kudiwa kana mota yave ichishandiswa kwenguva yakareba kana kuti iine daro rakareba; Zvisinei, kana mota ikashandiswa kwenguva pfupi kana kuti iine daro diki, unogona kufunga nezvekuramba uchishandisa zvikamu zvepakutanga pakugadzirisa.
Chii chinonzi egr valve?
Vharuvhu yekudzoreredza kutenderera kwegesi
Vharuvhu yeEGR ivharuvhu yekudzokorodza magasi emhepo. Ichi chigadzirwa chekubatanidza ma electromechanical chakaiswa painjini yedhiziri kudzora huwandu hwemagasi emhepo anodzokorodza anodzoserwa kuhurongwa hwekudyara, uye chinhu chakakosha uye chakakosha mumudziyo wekudzokorodza magasi emhepo.
Basa guru revharuvhu reEGR nderekudzora huwandu hwegasi rinobuda mumhepo rinopinda mumhepo, kuitira kuti huwandu hwakati hwegasi rinobuda mumhepo ripinde mumhepo rinodzoka mumhepo. Rinowanzo kuwanikwa kurudyi rwemhepo inobuda, pedyo nepaburi remagetsi, uye rinoona huwandu hwegasi rinobuda mumhepo rinoendeswa kumhepo rinobuda nechiyero chekuvhurwa kwevharuvhu rinodzorwa nechubhu ye vacuum. Nekutungamira gasi rinobuda mumhepo kubva pamoto weinjini kuenda kumhepo inobuda mumhepo kuti riite basa rekutsva, vharuvhu reEGR rinogona kuderedza tembiricha yekamuri rinopisa, kuvandudza kushanda zvakanaka kweinjini, kuvandudza nzvimbo inopisa, uye kuderedza mutoro weinjini. Panguva imwe chete, rinogona kuderedza zvinobudirira kuburitswa kwemakemikari ecarbon monoxide, kuderedza kugogodza, uye kuwedzera hupenyu hwebasa hwechikamu chimwe nechimwe.
Pamusoro pezvo, mavharuvhu eEGR akakamurwawo kuita mhando mbiri dzekudzora kwemuchina nemagetsi kuti zvienderane nezvinodiwa nemainjini akasiyana. Muinjini yemazuva ano inodzorwa nemagetsi, kuti inyatso dzora huwandu hwemhepo inobuda, nzira yekudzora yakavharika inoshandiswawo, uye sensor yechikamu inoiswa pavharuvhu yeEGR kuti inzwe mamiriro ekushanda kweinjini munguva chaiyo, uye zvichienderana neruzivo urwu, vharuvhu yeEGR inogadziriswa kuti ivhurike uye ivhare, kuitira kuti iwane kutonga kwakarurama kwehuwandu hwemhepo inobuda.
Vharuvhu yemotokari yakatyoka ine chiratidzo chipi?
Ndezvipi zviratidzo zviri pachena zvaunogona kuona kana vharuvhu yeEGR yemotokari yako ikakundikana?
Vharuvhu yeEGR, vharuvhu yemagetsi inoburitsa mweya, kana isina kushanda zvakanaka, mota inoonekwa sechiratidzo chekunyevera. Chekutanga, kusagadzikana kwemotokari kana kutodzima moto chinhu chinowanzoitika, uye mwenje wemagetsi unogona zvakare kupenya kakawanda kukuyeuchidza kuti utarise mamiriro einjini. Chechipiri, nekuti vharuvhu yeEGR inogona kutungamira mukubuda kwemhepo kusina kunaka, mota inogona kusangana nekunyara kwekukundikana kupasa bvunzo yegore negore.
Kana vharuvhu yeEGR ikachengetwa yakavhurika, mhedzisiro yacho inonyanya kukosha: mota icharatidza utsi hutema uye kusamhanya, ukuwo kushandisa mafuta zvakanaka kuchiderera uye kushandiswa kwemafuta kuchikwira. Kusiyana neizvi, kana vharuvhu yeEGR yakavharwa, kuburitsa utsi kuchakanganiswa uye zvinogona kukonzera kutadza kupasa mitemo yekuongorora yegore negore.
Kana zviri zvikonzero zvekukuvadzwa kwevharuvhu reEGR, pane zvinhu zvakawanda: matambudziko emhando yemagetsi anodzokororwa, kugadziriswa zvisina kunaka, mafuta asina kunaka uye kukwegura kwevharuvhu pachayo. Semuenzaniso, kushandiswa kwepeturu isina kuchena zvakanyanya kana kuwedzerwa mafuta zvisina kunaka kunogona kuva chinhu chinokurumidza kukonzera kutadza kushanda kwevharuvhu reEGR. Mavharuvhu eEGR anoshanda pakupisa kwakanyanya kweinjini, uye nekufamba kwenguva, senge mavharuvhu emakamuri ekufukidza makamuri nemarubha, anokwegura nekuda kwekusakara.
Kazhinji, hutano hwevharuvhu reEGR hwakakosha kuchengetedza mashandiro einjini uye kuburitsa mweya kubva munzvimbo inotonhorera, kana zviratidzo zvataurwa pamusoro apa zvawanikwa, nyanzvi dzinofanira kutsvaga kugadziriswa nekukurumidza kuitira kuti kuchengetedzwa kwekutyaira uye zvinodiwa nenharaunda zvizadzikiswe.
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonerei kana muchida zvigadzirwa zvakadaro.
