Valavu ya EGR (valavu yobwerezabwereza mpweya wotulutsa utsi) ndi chinthu chopangidwa ndi makina chomwe chimayikidwa pa injini ya dizilo kuti chiwongolere kuchuluka kwa mpweya wotulutsa utsi womwe umabwerera ku dongosolo lolowera mpweya.
Valavu ya EGR ndi chinthu chopangidwa ndi makina chomwe chimayikidwa pa injini ya dizilo kuti chiwongolere kuchuluka kwa mpweya wotuluka womwe umabwerera ku dongosolo lolowera. Nthawi zambiri imakhala kumbali yakumanja ya manifold ya intake, pafupi ndi throttle body, ndipo imalumikizidwa nayo ndi chubu chaching'ono chachitsulo chopita ku manifold ya intake. Ntchito yake ndikuwongolera kuchuluka kwa mpweya wotuluka womwe umalowa mu intake manifold, kuti mpweya wotuluka wina ulowe mu intake manifold kuti ubwererenso. Valavu ya EGR ndi gawo lofunikira kwambiri komanso lofunikira kwambiri mu chipangizo cholowera mpweya wotuluka.
Valavu ya EGR imagawidwa m'mitundu iwiri: mtundu wa makina ndi mtundu wowongolera zamagetsi.
Valavu ya EGR imachepetsa kutentha kwa chipinda choyaka moto mwa kutsogolera mpweya wotuluka kuchokera ku kuyaka kwa injini kupita ku intake manifold kuti ugwire nawo ntchito yoyaka, kukonza bwino ntchito ya injini, kukonza malo oyatsira moto, ndikuchepetsa katundu pa injini, kuchepetsa kutulutsa kwa NO compounds, kuchepetsa kugogoda, ndikuwonjezera nthawi ya moyo wa ntchito ya gawo lililonse.
Dzina lonse ndi Exhaust Gas Recirculation, kutanthauza, exhaust gas recirculation [1] Dongosololi limagwiritsidwa ntchito kuchepetsa kutulutsa kwa nitrogen oxides (NOX) mu exhaust gas. Nayitrogeni ndi okosijeni zimagwira ntchito mwa mankhwala pokhapokha kutentha kwambiri komanso kupanikizika kwambiri, ndipo kutentha ndi kupanikizika mu chipinda choyaka moto cha injini zimakwaniritsa izi, makamaka panthawi yokakamiza kuthamanga. Injini ikagwira ntchito pansi pa katundu, valavu ya EGR imatsegulidwa, zomwe zimapangitsa kuti mpweya wochepa woyaka moto ulowe mu intake manifold ndikulowa mu chipinda choyaka moto pamodzi ndi chisakanizo choyaka. Vavu ya EGR imatsekedwa idle, ndipo mpweya wochepa woyaka moto umabwereranso ku injini. Gasi woyaka moto wagalimoto ndi mpweya wosayaka (wopanda mafuta ndi okosijeni) womwe sumalowa nawo mu chipinda choyaka moto. Umachepetsa kutentha ndi kupanikizika kwa moto poyamwa gawo la kutentha komwe kumapangidwa ndi kuyaka kuti achepetse kupanga kwa nitrogen oxides. Kuchuluka kwa mpweya woyaka moto wolowa mu chipinda choyaka moto kumawonjezeka ndi liwiro la injini ndi katundu.
Kubwerezabwereza mpweya wotulutsa mpweya ndi njira yomwe gawo la mpweya wotulutsa mpweya limalowetsedwa mu mpweya watsopano wopumidwa (kapena wosakaniza) panthawi yogwira ntchito ya injini, ndikubwezeredwa ku silinda kuti ibwererenso kuti igwire nawo ntchito yoyaka. Ntchito yake ndikuchepetsa kutulutsa kwa NOx. NOx ndi mpweya woopsa kwambiri m'thupi la munthu, womwe umapangidwa makamaka kutentha kwambiri komanso mpweya wochuluka. Panthawi yogwira ntchito ya injini, ngati gawo la mpweya wotulutsa mpweya libwezeretsedwanso mu silinda nthawi yake komanso moyenera, chifukwa gawo lalikulu la mpweya wotulutsa mpweya lili ndi mphamvu yayikulu yotentha, CO2, mpweya wotulutsa mpweya ukhoza kuyamwa gawo la kutentha komwe kumapangidwa ndi kuyaka ndikutulutsa mu silinda, ndipo kumakhudza bwino chisakanizocho. Kuchepetsa kutentha komwe kumachitika chifukwa cha kuyaka kwa injini, motero kuchepetsa kupanga kwa mankhwala a NOx.
Komabe, kubwerezabwereza kwa mpweya wotulutsa mpweya kwambiri kudzakhudza magwiridwe antchito abwinobwino a injini, makamaka injini ikakhala ikuyenda pa liwiro lopanda ntchito, liwiro lochepa komanso katundu wochepa ndipo injini ikuyenda mozizira, ndipo mphamvu ya injini ikafunika pa katundu wonse (full throttle), kubwerezabwereza kwa mpweya wotulutsa mpweya kumakhudza kwambiri magwiridwe antchito a injini. Chifukwa chake, kuchuluka kwa mpweya wotulutsa mpweya womwe umagwira ntchito pa kubwerezabwereza kwa mpweya kuyenera kusinthidwa kokha malinga ndi momwe injini imagwirira ntchito komanso kusintha kwa momwe imagwirira ntchito. Kafukufuku wasonyeza kuti, malinga ndi kapangidwe ka injini kosiyana, kuchuluka kwa mpweya wotulutsa mpweya womwe umagwira ntchito pa kubwerezabwereza kwa mpweya nthawi zambiri kumasiyana pakati pa 6% ndi 13%.
Kuti kuchuluka kwa mpweya wotulutsa mpweya kusakhudze kwambiri magwiridwe antchito a injini, mainjini amakono olamulidwa ndi magetsi amagwiritsanso ntchito njira yowongolera yotseka kuzungulira kwa mpweya wotulutsa mpweya, ndipo sensa ya malo a valve ya EGR imayikidwa pa valavu yobwezeretsanso mpweya wotulutsa mpweya (mitundu ina imagwiritsanso ntchito masensa otentha a mpweya wotulutsa mpweya). kapena sensa yokakamiza), kuwongolera kwa closed-loop kukonza kwa kuchuluka kwa mpweya wotulutsa mpweya kumachitika. Malo oyendera bizinesi. Kutalika kwa pansi kuchokera pansi ndi kochepa, ndipo kuchuluka kwa malo ogwiritsira ntchito mkati ndikokwera kwambiri pakati pa zinthu zofanana, zomwe ndi 19% kuposa zomwe zimapangidwa ndi zinthu zofanana; malo akulu.
Yoyenera zochitika zosiyanasiyana, kuchuluka kwa chipinda chapakati cha axis yayitali ndi mpaka 10.2m³
Bokosi lake ndi lalikulu ndipo kuchuluka kwa zinthu zomwe zimagwiritsidwa ntchito kuli kwakukulu, malo ochulukirapo ndi 15% kuposa zinthu zofanana.
Mphamvu zazikulu
Injini ya dizilo ya SAIC π2.0T ya turbo
Mafuta omwe amagwiritsidwa ntchito pa 100 kilomita ndi otsika kufika pa 7.8L, mphamvu yayikulu ndi 102kW, ndipo torque yayikulu ndi 330N m

Sitima yapamtunda ya 2000bar yokhala ndi mphamvu yayikulu, imachepetsa kugwiritsa ntchito mafuta ndi 20% bwino, komanso imachepetsa kugwiritsa ntchito mafuta ndi 20%.
Yokhayo m'gulu lake ili ndi magiya odziyimira okha a 6-speed, switching yanzeru, komanso yogwiritsa ntchito mafuta pang'ono ndi 5%.
Kulamulira mwanzeru
Giya yolumikizira ya 6AMT, yomwe ndi yolumikizira pakati, imatha kusankha mitundu yosiyanasiyana ya giya ya 6MT, 6AMT, giyayo ndi yofewa komanso yosalala, ndipo yowongolerayo ndi yosavuta komanso yosavuta.
Kukonza chassis yaukadaulo ya MIRA molimbika komanso mwapamwamba kumapereka kumverera koyendetsa kofanana ndi kwa galimoto yonyamula anthu. Ukadaulo woyimitsa mpweya ukhoza kusintha kwambiri kuthekera kodzipatula kwa kugwedezeka kwa msewu, ndikuwonjezera bwino malire owongolera komanso chitonthozo [19]
