Valve ya EGR (valavu yotulutsa mpweya wotulutsa mpweya) ndi makina opangira makina omwe amaikidwa pa injini ya dizilo kuti athe kuwongolera kuchuluka kwa mpweya wotulutsa mpweya womwe umabwezeretsedwanso ku dongosolo lolowera.
Valve ya EGR ndi chinthu chamagetsi chomwe chimayikidwa pa injini ya dizilo kuti chiwongolere kuchuluka kwa mpweya wotulutsa mpweya womwe umabwezeretsedwanso ku dongosolo lodya.Nthawi zambiri imakhala kumanja kwa njira yolowera, pafupi ndi thupi la throttle, ndipo imalumikizidwa nayo ndi chubu chachifupi chachitsulo chomwe chimatsogolera kuzinthu zambiri zotulutsa.Ntchito yake ndikuwongolera kuchuluka kwa mpweya wotulutsa mpweya womwe umalowa munjira zambiri, kotero kuti kuchuluka kwa mpweya wotulutsa mpweya kumadutsa munjira zambiri zomwe zimapangidwira kuti zibwezeretsedwe.Valve ya EGR ndi gawo lofunika kwambiri komanso lofunikira kwambiri pa chipangizo chothamangitsa mpweya wotulutsa mpweya.
Vavu ya EGR imagawidwa m'mitundu iwiri: mtundu wamakina ndi mtundu wowongolera zamagetsi.
Valavu ya EGR imachepetsa kutentha kwa chipinda choyaka moto potsogolera mpweya wotuluka kuchokera kuyaka kwa injini kupita kumalo ochulukirapo kuti atenge nawo mbali kuyaka, kuwongolera magwiridwe antchito a injini, kukonza malo oyatsira moto, ndi kuchepetsa katundu injini, kuchepetsa kutulutsa kwa NO mankhwala, kuchepetsa kugogoda, ndi kutalikitsa nthawi ya chigawo chilichonse.moyo wautumiki.
Dzina lonse ndi Exhaust Gas Recirculation, ndiko kuti, kutulutsa mpweya wotulutsa mpweya [1] Dongosololi limagwiritsidwa ntchito kuchepetsa kutulutsa kwa nitrogen oxides (NOX) mu mpweya wotulutsa mpweya.Nayitrojeni ndi okosijeni amachita mwamankhwala pokhapokha kutentha kwambiri komanso kupanikizika kwambiri, ndipo kutentha ndi kupanikizika m'chipinda choyaka cha injini zimakumana ndi izi, makamaka panthawi yokakamiza.Pamene injini ikuyenda pansi pa katundu, valavu ya EGR imatsegula, kulola kuti mpweya wochepa pang'ono ulowe m'chipinda choyatsira moto pamodzi ndi kusakaniza koyaka.Valve ya EGR imatsekedwa popanda ntchito, ndipo mpweya wotopa pang'ono umabwerezedwanso ku injini.Gasi wotulutsa galimoto ndi gasi wosayaka (wopanda mafuta ndi oxidant) yemwe satenga nawo gawo pakuyaka muchipinda choyaka.Amachepetsa kuyaka kutentha ndi kupsyinjika mwa kuyamwa mbali ya kutentha kopangidwa ndi kuyaka kuti kuchepetsa kupanga kwa nitrogen oxides.Kuchuluka kwa mpweya wotulutsa mpweya wolowa m'chipinda choyaka kumawonjezeka ndi liwiro la injini ndi katundu
Kuthamangitsidwa kwa mpweya wotulutsa mpweya ndi njira yomwe gawo la mpweya wotulutsa mpweya umalowetsedwa mu mpweya wabwino (kapena wosakaniza) panthawi yogwira ntchito ya injini, ndikubwereranso ku silinda kuti ibwezeretsedwenso kuti iwonongeke.Ntchito yake ndikuchepetsa kutulutsa kwa NOx.NOx ndi mpweya woopsa kwambiri m'thupi la munthu, womwe umapangidwa makamaka ndi kutentha kwambiri komanso mpweya wabwino.Panthawi yogwira ntchito ya injini, ngati gawo la mpweya wotulutsa mpweya umalowetsedwanso mu silinda mu nthawi yake komanso yoyenera, chifukwa gawo lalikulu la mpweya wotulutsa mpweya uli ndi kutentha kwakukulu, CO2, mpweya wotulutsa mpweya ukhoza kuyamwa mbali. za kutentha kopangidwa ndi kuyaka ndikuzichotsa mu silinda, ndipo zimakhala ndi zotsatira zabwino pa kusakaniza.Zomwe zimapangidwira, motero kuchepetsa kutentha kwakukulu ndi mpweya wa mpweya wa injini, motero kuchepetsa mapangidwe a NOx.
Komabe, kutulutsa mpweya wochulukirapo kumakhudza magwiridwe antchito a injini, makamaka pamene injini ikugwira ntchito pa liwiro lopanda pake, liwiro lotsika komanso lotsika, ndipo injini ikugwira ntchito pozizira, ndipo mphamvu ya injini ikafunika kunyamula. (kuthamanga kwathunthu), kubwereza kwa mpweya wotulutsa mpweya kudzakhala ndi vuto lalikulu pakugwira ntchito kwa injini.Choncho, kuchuluka kwa mpweya wotulutsa mpweya womwe umalowa mu recirculation uyenera kusinthidwa molingana ndi momwe injini ikugwirira ntchito komanso kusintha kwa ntchito.Zochita zatsimikizira kuti, malinga ndi makina osiyanasiyana a injini, kuchuluka kwa mpweya wotulutsa mpweya womwe umakhudzidwa ndi kubwereza nthawi zambiri kumasiyana pakati pa 6% ndi 13%.
Pofuna kuti kuchuluka kwa mpweya wotulutsa mpweya kusakhale ndi mphamvu yochuluka pa injini, injini zamakono zoyendetsedwa ndi magetsi zimagwiritsanso ntchito njira yotsekera yotseketsa mpweya wotulutsa mpweya, ndi EGR valve position sensor imayikidwa pa mpweya wotulutsa mpweya. valve (zitsanzo zina zimagwiritsanso ntchito zowunikira kutentha kwa gasi).kapena kupanikizika sensa), kutsekedwa-kuwongolera kuwongolera ndemanga kuwongolera kwenikweni kutulutsa mpweya wotulutsa mpweya kumachitidwa. Malo oyenda bizinesi.Kutalika kwa pansi kuchokera pansi kumakhala kochepa, ndipo kuchuluka kwa malo ogwiritsira ntchito malo amkati ndipamwamba kwambiri pakati pa zinthu zofanana, zomwe ndi 19% kuposa zomwezo; malo aakulu.
Zokwanira pamitundu yosiyanasiyana, kuchuluka kwa chipinda chapakati chapakatikati mpaka 10.2m³
Bokosi la bokosi ndi lalikulu ndipo kuchuluka kwa kugwiritsidwa ntchito ndikokwera, 15% malo ochulukirapo kuposa zinthu zofanana
Mphamvu zapamwamba
SAIC π2.0T turbo injini ya dizilo
Kugwiritsa ntchito mafuta pa 100km ndi otsika ngati 7.8L, mphamvu pazipita ndi 102kW, ndi makokedwe apamwamba ndi 330N m.
Phokoso la idling limafika kuofesi ya 51dB yokha
2000bar high pressure common njanji, bwino mafuta atomization kwenikweni, kuchepetsa kumwa mafuta ndi 20%
Ndi imodzi yokha m'kalasi yake yomwe ili ndi 6-speed automatic transmission, yosintha mwanzeru, ndi 5% yowonjezera mafuta.
Kuwongolera mwanzeru
6AMT manual kufala, chapakati ulamuliro Integrated zida, akhoza kusankha 6MT, 6AMT zosiyanasiyana kufala mitundu, zida ndi yofewa ndi yosalala, ndi kulamulira ndi yabwino ndi yosavuta.
Kuwongolera kolimba, kokhazikika kwaukadaulo wa MIRA kumapereka kumverera koyendetsa kofanana ndi kwagalimoto yonyamula anthu.Ukadaulo wa kuyimitsidwa kwa mpweya ukhoza kupititsa patsogolo luso la kudzipatula kwa msewu, ndikuwongolera malire ndi chitonthozo [19]
Wodalirika komanso wokhazikika
Pepala lachitsulo lopangidwa ndi mbali ziwiri, EPP wokometsera madzi osasungunuka utoto, njira zinayi zochizira utoto wa phosphating, electrophoresis, zokutira zapakati ndi topcoat kuti zitsimikizire kuti sizikhala ndi dzimbiri kwa zaka 10.(Mulingo wadziko lonse umafunikira zaka 7)
【Chitetezo Chokwanira】: Thupi lonyamula katundu lomwe lili ndi mawonekedwe ophatikizika, a khola
Muyezo wa kapangidwe ka chitetezo ku Europe, magawo ofunikira amthupi amapangidwa ndi chitsulo champhamvu kwambiri, kuchuluka kwake kumafika 50%, ndipo pafupifupi 30% yokha yazinthu zofanana.
M'badwo waposachedwa wa Bosch ESP9.1 electronic stability assistance system ukuphatikizapo ABS, EBD, BAS, RMI, VDC, HBA, TCS ndi machitidwe ena, omwe amatha kuyang'anira momwe alili nthawi iliyonse pakuyendetsa kuti apewe kutsetsereka m'mbali mwagalimoto ndikugwedezeka panthawi ya braking. mchira wa ngodya kuti mutsimikizire chitetezo pamakona.
