Pehea e holo ai ka EGR kiwikā?

Mau kanaka ike, akā, ka mea, o ke aloha i ka EGR hiki me ka nui loa ho'ēmi i kaa wahie hokii,? Ienoai engine hana ana, normalize kona ana a me ka emi ka nui o ka detonation. Aia ka ia i ka'ōnaehana ua he lōʻihi manawa, a ma ka manawa ka mea, ua noi pono ma luna o nā mea a pau kaa. A hiki ma ka ", ako" o ke aupuni, he mea e like me ka noonoo o kanaka.

No ke aha la keia'ōnaehana mākou e pono ai?

Recirculation o kinoea a no ka maluhiluhi ua pono ai ma ka mea ana o ka engine i ole ka liu o kona mana no ka ea puka o unburnt wahie residues. A me keia ia lŘlŘ like penei. Inā ke ana wela i loko o ka'ā keena a pau me ka o oxygen, naikokene hoʻomaka e lilo nitric'okesaside. Ma ke kakolina engine O2 e pono ai no ka efficient'ā o ka wahie, a no ka mea, ho'ēmi i kā ka mea nui o ka naikokene, i ka wai a ua ole loa combusted. E like me ka hopena, kakolina wale kinoea i loko o ke paipu, wahie hokii, piʻi pū, a me keia emi i ka hana ana o ka mea maloko'ā engine. Ka EGR kiwikā e leie aku i ka wahie i kuni i ka mea mai ma mua o ka pau ana o ka manawa kūpono, no laila, ua normalized mana a me ka wahie hokii, i loko o ke kaa.

He aha ka ka nohona kiwikā o?

Ma nānaina o ka uuku, pā hōkū me ka Tube a ua pili i kaʻai ana nui loa, a ua pili i ka paukūʻolokaʻa poo. Ma ka quiescent moku'āina ka a no ka maluhiluhi kinoea recirculation kiwikā ( "Audi" me) Ua paʻa. Akā, i ka wā i ka engine wahie i lako i, ka mea, ua actuated. ea holo i hanaʻia i loko o ka? aieeeua, koa e neʻe i kaʻili lahilahi, a me ka ia, ma ka huli, wehe ka EGR kiwikā.

? ueo

Currently, loaʻa nō kekahi mau 'ano o kaʻikepili na manao ona. Ke EGR kiwikā mea mechanically (ma ka huli māheleʻia i loko o elima ka hoʻololi 'ana) a me ka lolouila (3 ma laila nā loli).

He aha ka mea e hana nei?

Kēiaʻano papa hana o ke ki ke keʻena o ka recirculation nenoaiu. Ua hoʻi hoʻi kuleana waiwai i kuni ai i kaʻai ana nui loa , a ua hui ia me ka lewa. Ka hope, i ka huli, maoli ka'ā mahana (ma muli o ka o oxygen - O2). Penei, ma artificially hoemi kona maʻiʻo ma ke ka ho'ēmiʻana o keʻano o ka'ā ia lŘlŘ o ka wahie-ea ukuhiia. Oxygen ma reacts me ka naikokene, a no ka mea, o ka degere o ka mahana emi ai, ua lilo oi no laila, i loko o ke keʻena kakolina puhi loa.

Eia hou, o ka a no ka maluhiluhi kinoea recirculation kiwikā (BMW me) kūpono kou ho'ēmi i kā pumping poho, me he mea ia he ikaika kulu i loko o ka puʻuwai o ka throttle. Low'ā ana wela ho'ēmi i kā ka iliwai o ka detonation, i mea he pomaikai nui no ka Hawaii (ʻaʻohe ikehu poho). Me ka pili ana i ka kakolina diesel nā mea hoʻonoho 'aneʻi EGR kiwikā normalizes "paakiki" ana o ka Hawaii ma ka hana ole ana: mililani aku i ka mea kuu iho'ā mahana ho'ēmi i kā ka puʻe i loko o ke keʻena, no laila, he mea ikaika kuekueni.
