Sei EGR vharuvhu?

vanhu vashoma vanoziva, asi nemhaka EGR anogona kuderedza motokari mafuta kuparadzwa, kuvandudza injini kuita, normalize mashandiro awo uye kuderedza pachiyero detonation. Pane kudaro hurongwa iri nguva refu, uye panguva iyoyo nayo rinoshandisirwa zvakakwana pamotokari zvose. Kunyange National "Cornfield" pane mudziyo yakadaro.

Nei tichifanira ino?

Recirculation kuti chiutsi magasi chinodiwa kuti injini haana kurasa simba raro nokuda akabuda unburnt mafuta residues. Uye ichi kunoitika sezvinotevera. Kana tembiricha iri combustion mukamuri pamwe okisijeni, senitrogen dzinotanga kuumbika nitric oxide. Muna peturu injini O2 aida kuti vakarongeka combustion peturu, uye nokuti kunoderedza uwandu senitrogen, nemvura hauna combusted chose. Somugumisiro, peturu anongoti chaibwinya kupinda mutopota, mafuta zvinodyiwa kunowandawo, uye izvi zvinoderedza chokupika dzomunyika injini. The EGR vharafu anobvumira mafuta kutsva kuguma mukana pamberi, zvokuti normalized simba uye mafuta kudyiwa iri motokari.

Chii vharuvhu?

Tichifunga denderedzwa diki nomuchubhu iyo kwakabatana kuti yaunodya zhinji uye wanamatira humburumbira musoro. Munguva quiescent nyora chiutsi gasi recirculation vharafu ( "Audi" kusanganisira) ndiyo Akanyatsovharwa. Asi panongovira injini chinotsva romugove kunoitika, zvinonzi actuated. mhepo isina kuumbwa dura, Hunoita kutamisira Kamudzira, uye, uyewo, anovhura EGR vharuvhu.

mhando

Pari zvino pane marudzi vanoverengeka date mano. The EGR vharafu iri mechanically (zvinozoita rakakamurwa okunatsiridza shanu) uye yemagetsi (3 ipapo nadzurudzo).

Chii ari kuzviitirei?

mashandiro ichi chinokosha pakuderedza pamusoro recirculation hurongwa. It anodzoka shure mugove zvinhu kupiswa ari kudya zhinji uye mixes navo mhepo. Ekupedzisira, uyewo, inowedzera combustion tembiricha (nokuda okisijeni - O2). Saka, nokuda artificially kuderedza kwayo kugutsikana mune rutapudzo ane mwero combustion kunoitika pakati huni mhepo nezvakasanganiswa. Okisijeni ikasakendenga pamwe senitrogen, uye nekuti ukuru tembiricha kuderera, zvinoramba zvichitowedzera kukosha kudaro mukamuri peturu unopisa zvachose.

Mukuwedzera, pedza gasi recirculation vharafu (BMW kusanganisira) substantially kunoderedza kupomba kurasikirwa, sezvo pane yakadaro donhwe kwakasimba vomanikidza throttle. Low combustion tembiricha kunoderedza padanho detonation, riri nani zvikuru nokuti injini (hapana torque kurasikirwa). Panyaya Diesel zvivako pano EGR vharafu normalizes "zvakaoma" mudzimu injini pa chamunobata nemhaka chichiburutswa combustion tembiricha kunoderedza kumanikidzwa mukamuri, saka pane vibrations simba.
