Izimpawu Zesipholile se-EGR Esinephutha noma Esinephutha
Izimpawu ezijwayelekile zihlanganisa ukushisa kwenjini, ukuvuza kwe-exhaust, kanye nokukhanya kwe-Check Engine okuzayo.
I-cooler ye-EGR iyingxenye esetshenziselwa ukwehlisa izinga lokushisa lamagesi aphumayo aphinde ajikeleziswa uhlelo lwe-EGR. Uhlelo lwe-EGR luzungeza kabusha amagesi e-exhaust abuyele enjinini ukuze kwehliswe izinga lokushisa lesilinda kanye nokukhishwa kwe-NOx. Nokho, igesi ezungeza ohlelweni lwe-EGR ingashisa kakhulu, ikakhulukazi ezimotweni ezinezinjini zikadizili. Ngenxa yalesi sizathu, izinjini eziningi zikadizili zifakwe ama-coolers e-EGR ukuze ehlise izinga lokushisa lamagesi akhipha umoya ngaphambi kokuba angene enjinini.
I-cooler ye-EGR iyisisetshenziswa sensimbi esebenzisa amashaneli amancane namaphiko ukupholisa amagesi akhipha umoya. Zisebenza ngendlela efanayo ne-radiator, zisebenzisa umoya obandayo odlula emaphikweni ukuze zipholise amagesi akhipha umoya adlula endaweni epholile. Uma isipholile se-EGR sinezinkinga, singabangela izinkinga ngokusebenza kwesistimu ye-EGR. Lokhu kungaholela ezinkingeni zokusebenza ngisho nezinkinga zokudlulisa amazinga okukhishwa kwegesi ezifundazweni lapho edingeka khona. Ngokuvamile, isibandisi se-EGR esinephutha noma esinephutha sidala izimpawu ezimbalwa ezingaxwayisa umshayeli ngenkinga engaba khona okufanele ixazululwe.
1. Ukushisa kwenjini
Esinye sezimpawu zokuqala zenkinga ye-EGR epholile engaba khona ukushisa kwenjini. Uma isipholile se-EGR sinezinkinga ezikhawulela ukugeleza kwamagesi e-exhaust ngesipholile, lokhu kungabangela injini ukuba ishise ngokweqile. Ngokuhamba kwesikhathi, ikhabhoni ingakheka ngaphakathi kokupholisa kwe-EGR futhi ikhawulele ukugeleza kwesipholile. Lokhu kungaholela ekushiseni ngokweqile kweyunithi, emva kwalokho ngeke ikwazi ukupholisa amagesi okukhipha, futhi ngenxa yalokho, injini izoshisa kakhulu. Ukushisa kwenjini ngokweqile kungabangela injini ukushayeka noma ukushayisa futhi ngisho nomonakalo omkhulu uma inkinga ishiywe inganakiwe.
2. Ukuvuza kwe-exhaust
Enye inkinga nge-EGR cooler ukuvuza kwegesi yokukhipha. Uma ama-cooler gaskets e-EGR ehluleka noma okokupholisa konakale nganoma yisiphi isizathu, kungase kubangele ukuvuza kwegesi yokukhipha umoya. Ukuvuza kwe-exhaust kungase kuzwakale njengomsindo ozwakalayo noma umsindo ovela ngaphambili emotweni. Lokhu kuzonciphisa ukusebenza kahle kwesistimu ye-exhaust gas recirculation futhi kube nomthelela omubi ekusebenzeni kwenjini.
3. Hlola ukukhanya kwenjini kuyakhanya.
Olunye uphawu lwe-EGR cooler embi noma enephutha ukukhanya kwe-Check Engine. Uma ikhompuyutha ithola inkinga ngohlelo lwe-EGR, njengokugeleza okunganele noma ukukhipha umoya, izokhanyisa isibani senjini yokuhlola ukuze yazise umshayeli ngenkinga. Ukukhanya kwenjini yokuhlola kungabangelwa ezinye izinkinga eziningi, ngakho-ke kunconywa kakhulu ukuthi uskene ikhompuyutha yakho ukuze uthole amakhodi enkathazo.
Ama-coolers e-EGR awafakiwe kuzo zonke izimoto, kodwa ezimotweni ezihlome ngazo, abalulekile ekusebenzeni kwemoto nasekushayeleni. Noma yiziphi izinkinga nge-EGR cooler zingaholela ekukhiqizweni okuphezulu, okuzoba inkinga ezifundazweni ezidinga ukuhlolwa kwe-emission kuzo zonke izimoto zazo. Ngenxa yalesi sizathu, uma usola ukuthi isipholile sakho se-EGR kungenzeka sinenkinga, yiba nochwepheshe oqeqeshiwe, ofana nalowo ovela ku-AvtoTachki, cela imoto yakho ihlolwe ukuze kutholwe ukuthi ingabe isipholile kufanele sishintshwe yini.
