Nahea te piha EGR?
e matau ana torutoru iwi, engari he reira te whakawhetai ki te EGR taea tino whakaiti i waka kohi wahie, te whakapai ake mahi pūkaha, haerenga tona mahi, me te whakaiti i te taumata o te detonation. He he he pūnaha taua te he wa roa, me i te kau e tono tino i runga i waka katoa. Ahakoa i runga i te "koane" motu i reira ko te whakaaro taua.
He aha e hiahia ana tatou i tenei pūnaha?
Recirculation o hau whakapau hiahiatia te i roto i te tikanga e kore i te pūkaha tona kaha ngaro hoki paheke o ngā toenga wahie unburnt. Na tenei tupu e whai ake. Ki te te pāmahana i roto i te ruma ngingiha tahi ki te hāora, hauota timata ki te hanga i waikura nitric. I roto i te pūkaha penehīni hiahiatia O2 mō te ngingiha pai o wahie, a no te mea te whakaiti reira te nui o te hauota, e kore te tino ngingihatia te wai. Ka rite ki te hua, penehīni tukuna noa ki te putorino, piki wahie kohi, me tenei heke te mahi o te pūkaha ngingiha ā-. Te piha EGR taea te wahie tahu i te aroaro o te mutunga o te pea, kia kaha, me te wahie kohi tonu o roto i te waka.
He aha te mea te piha?
I roto i te tirohanga o te kōpae iti ki te ngongo hono nei te ki te maha horomanga me te piri ki te matenga puoto. I roto i te āhua āta te whakapau hau recirculation takirere ( "Audi" tae atu) he kuiti. Ko te taenga atu ano te supply wahie pūkaha puta, kua timataria ai reira. rangi korehau i hanga i roto i te awa ki, taruke ki te neke i te membrane, a reira, i roto i tahuri, oroko te piha EGR.

Ko te whakamutunga, i roto i te tahuri, faarahi te pāmahana ngingiha (e tika ana ki te hāora - O2). Ko te kupu, e āwenewene whakaiti tona ihirangi i roto i te whakaiti o te tohu o te ngingiha puta o te ranunga wahie-rangi. tauhohe hāora ki hauota, me te mea te tohu o te pāmahana heke, riro te reira atu na i roto i te penehīni ruma kaitahu tino.
I tua atu, i te piha whakapau hau recirculation (BMW tae) nui whakaiti kutētē mate, rite reira he he taua te maturuturunga iho kaha i roto i te pēhanga ki runga i te kātere. Iti pāmahana parariraa te whakaiti i te taumata o te detonation, i te mea he painga nui mo te nekeneke (kahore parekura taipana). Ki te whakaaro ki tāuta diesel konei EGR takirere normalizes "pakeke" mahi o te pūkaha i mangere: whakawhetai ki te pāmahana ngingiha tuku iho te whakaiti te pēhanga i roto i te ruma i, na reira he wiri kaha.
