Njani na umba EGR?

Bambalwa abantu bazi, kodwa sibamba ngazibini ke EGR unga nciphisa ngokubaluleka ukusetyenziswa kwamafutha kwezithuthi, ukuphucula intsebenzo injini, ukulungisa ukusebenza kwayo nokunciphisa inqanaba detonation. Kukho indlela eso ixesha elide, kwaye kwavele lisetyenziswa ngokugqibeleleyo zonke izithuthi. Nokuba kwi "kwifama" yesizwe kukho sixhobo.

Kutheni sifuna le nkqubo?

Recirculation of iigesi zeemoto efunekayo ukuze injini khange baphelelwe ngamandla ayo amadlozi zeentsalela amafutha unburnt. Kwaye oku kwenzeka ngolu hlobo lulandelayo. Ukuba lobushushu egumbini yokutsha kunye ioksijini, nitrogen baqale-nitric oxide. Xa injini ipetroli O2 ezifunekayo ukutshiswa kakuhle zepetroli, yaye kuba lunciphisa isixa-nitrogen, i-ulwelo hayi combusted ngokupheleleyo. Ngenxa yoko, ipetroli ekhutshwa nje angena kumbhojana, ukunyuka amafutha, kwaye oku kunciphisa komsebenzi injini yokutsha lwangaphakathi. I EGR valve ivumela amafutha ecima phambi kokuphela ithuba, ukuze ukusetyenziswa kwamandla kunye amafutha nganye ezinga malungu abantu kwisithuthi.

Yintoni na vana?

Ngenxa idiski encinane ityhubhu oludityaniswe ngayo izinto eziphindaphindiweyo esingena kwaye iqhotyoshelwe intloko njengesilinda. Xa urhulumente quiescent qeda recirculation igesi vana ( "Audi" kuquka) evaliwe. Kodwa kamsinya nje amafutha injini kwenzeka, kokuba actuated. Sivula umoya eqalisiweyo dama, onyanzelisa ukususa inwebu, kwaye, yena, kuvula EGR vana.

uhlobo

Okwangoku, kukho iintlobo ezininzi izixhobo data. Ivelufa EGR yi zoomatshini (yena yahlulwe ukuguqulwa ezintlanu) kunye ngekhompyutha (3 apho ukuguqulwa).

yena wenza ntoni?

Le ndlela ngoyena ndoqo kwinkqubo recirculation. Ibuyisela umva izinto isahlulo zizitshise le ngezilingo esingena kwaye ixutywa kuwo umoya. Nevuthisayo ngexesha ke, kwandisa lobushushu yokutsha (ngenxa mpilo - O2). Ngenxa yoko, ngenxa eyenziweyo ngokunciphisa nokuqulethileyo ngokucuthwa iqondo yokutsha lwenzeka umxube amafutha-moya. Ioksijini idityaniswe nitrogen, nangenxa iqondo lobushushu nciphisa, kuya kuba njalo kwi ipetroli egumbini isha ngokupheleleyo.

Ukongeza, ivelufa zeemoto recirculation gas (BMW kubandakanywa) kakhulu kunciphisa zokumpompa ilahleko, njengoko kukho ukuhla olomeleleyo kwingcinezelo enjalo phezu umcephe wokunyusa. lobushushu yokutsha Low kunciphisa inqanaba detonation, nto leyo inzuzo enkulu ukuba imoto (akukho ilahleko torque). Ngokumalunga ufakelo apha idizili EGR vana normalizes "nzima" ukusebenza isithuthi niyahiliza, ngenxa lobushushu yokutsha bazifinyeza kunciphisa uxinzelelo egumbini, ngoko kukho intlokoma eyomeleleyo.
