Mayendedwe oyesa akuwonetsa injini yatsopano ya Opel 2,0 CDTI

Mbadwo watsopano wamagulu akuluakulu a dizilo unayamba ku Paris

Mphamvu yayikulu, makokedwe apamwamba, mafuta ochepa komanso mpweya wotulutsa mpweya wophatikizidwa ndi kukonzanso kotsogola: Injini yatsopano ya Opel 2,0-lita ya dizilo ndiwosintha konse. Injini yaukadaulo kwambiri iyi, yomwe idayamba ku Insignia ndi Zafira Tourer ku 2014 Mondial de l'Automobile ku Paris (Okutobala 4-19), ikuwonetsa gawo lina pakupanga injini yatsopano ya Opel.

Chigawo chatsopano chokhala ndi 125 kW / 170 hp. ndipo makokedwe okhumbirika a 400 Nm amalowa m'malo mwa injini ya 2,0 CDTI (120 kW / 163 hp) pamwamba pamzere wa dizilo wa Opel. Makina oyenera a Euro 6 amapereka mphamvu zowonjezera pafupifupi 14% ndi makokedwe a 2%, komanso amachepetsa kugwiritsa ntchito mafuta ndi mpweya wa COXNUMX. Chofunikanso kwambiri, injini imayenda mwakachetechete komanso moyenera, zotsatira zakugwira ntchito molimbika kwa akatswiri aukadaulo a Opel kuti achepetse phokoso, kunjenjemera komanso nkhanza.

"Injini yapamwambayi ndiyomwe imagwirizana kwambiri ndi zitsanzo zathu zazikulu za Insignia ndi Zafira Tourer," adatero Michael Abelson, wotsatila pulezidenti wa Vehicle Engineering Europe. "Kuchulukirachulukira kwake kwamagetsi, magwiridwe antchito abwino, chuma chake komanso zosangalatsa zamagalimoto zimapangitsa kuti ikhale imodzi mwamainjini apamwamba kwambiri a dizilo m'gulu lake. 6 CDTI yatsopano ikugwirizana ndi Euro 2,0 ndipo ikukwaniritsa zofunikira zamtsogolo ndipo ipangitsa kuti injini yathu ya dizilo ikhale yokongola kwambiri.

Injini yatsopano ya 2,0 CDTI, yomwe iyamba kupanga chaka chamawa, idzakhala yoyamba pamzere watsopano wa injini zazikulu za dizilo zopangidwa ndi kampaniyo. Ntchitoyi idakhazikitsidwa ndi akatswiri padziko lonse lapansi ochokera ku Turin ndi Rüsselsheim mothandizidwa ndi anzawo aku North America. Idzapangidwa ku Opel ku Kaiserslautern, Germany.

Kuchulukitsa mphamvu zamagetsi ndikuchepetsa mafuta ndi mpweya

Kuchotsa kuchuluka kwa mphamvu padontho lililonse lamafuta ndiye chinsinsi chothandizira mphamvu zazikulu zonse mwatsatanetsatane komanso molingana ndi kuchuluka kwa mphamvu, zomwe zimafotokozedwa ngati mtengo wa 85 hp. / l - kapena mphamvu yeniyeni yofanana ndi injini. kuchokera ku m'badwo watsopano wa Opel 1.6 CDTI. Njinga yatsopanoyi imatsimikizira kuyendetsa bwino popanda kusokoneza bajeti yamakasitomala. Chochititsa chidwi cha 400 Nm cha makokedwe chilipo kuchokera ku 1750 mpaka 2500 rpm ndi mphamvu yotulutsa 125 kW / 170 hp. adangofikira 3750 rpm.

Zina mwa zinthu zofunika kwambiri kuti mukwaniritse mawonekedwe agalimoto ndi chipinda choyaka moto, mawonekedwe owonjezera opangidwanso ndi jakisoni watsopano wamafuta omwe ali ndi mphamvu yayikulu ya 2000, ndikuthekera kwa jakisoni 10 pozungulira. Mfundo imeneyi ndi maziko a kukwaniritsa mkulu mlingo wa mphamvu, ndi bwino mafuta atomization kumapanga zofunika kuti ntchito modekha. Kusankhidwa kwa mawonekedwe a chipinda choyaka moto chokha ndi zotsatira za kusanthula kwa makompyuta oposa 80, asanu omwe anasankhidwa kuti apite patsogolo.

VGT (Variable Geometry Turbocharger) turbocharger imakhala ndi chida chowongolera chowongolera magetsi, chomwe chimapereka kuyankha mwachangu kwa 20% kuposa kuyimitsidwa. Makina ophatikizika kwambiri a VGT turbocharger ndi intercooler amachepetsa mpweya pakati pa kompresa ndi injini, kupititsa patsogolo nthawi yowonjezera. Kupititsa patsogolo kudalirika kwa turbocharger, chipangizocho chimakhazikika m'madzi ndipo fyuluta yamafuta imayikidwa panjira yolowera mafuta, yomwe imachepetsa kukangana pakamagwira ntchito.

Turbocharger ndi utsi mpweya recirculation (EGR) gawo limaphatikizidwa mumapangidwe amodzi kuti apange bwino kwambiri. Gawo la EGR limakhazikika pamalingaliro atsopano okhala ndi radiator yazitsulo zosapanga dzimbiri zomwe zimapereka kuziziritsa kwama 90%. Mafuta ophatikizika otulutsa madzi otsekemera omwe amalowetsa pansi amachepetsa kutsika kwa kuthamanga ndipo kuyendetsa kwake kotsekedwa kumachepetsa kwambiri nitrogen oxide ndi particulate matter (NOx / PM) potulutsa zinthu pakasinthidwe kazinthu, ndikukweza mpweya. ma hydrocarboni ndi carbon monoxide (HC ndi CO).

Yosalala ntchito: Dizilo mphamvu ndi ntchito yeniyeni ngati chopangira mphamvu mpweya

Kusintha kwakumaso kwa phokoso ndi kugwedera m'njira zonse zogwirira ntchito kwakhala kofunikira pakukonza injini yatsopano kuyambira pomwe ntchito yayikulu idamalizidwa. Mitundu yambiri yamakompyuta yama Computer Aided Engineering (CAE) idagwiritsidwa ntchito popanga ndikusanthula gawo lirilonse lisanachitike injini yoyamba.

Kusintha kwa zomangamanga kumayang'ana mbali ziwiri zomwe zimapanga phokoso lalikulu: pamwamba ndi pansi pa injini. Kapangidwe katsopano ka mutu wa aluminiyamu, kuphatikiza kuwonjezera kwa boneti yamagetsi yama polima yokhala ndi mapangidwe olekanitsa ndi gasket, imathandizira kuchepetsa phokoso. Zochulukitsa zambiri zimatsekedwa ndichinthu chimodzi chotsekereza mawu.

Pansi pa injiniyo pali module yatsopano yothamanga kwambiri yopanga zotayidwa. Imakhala ndi zitsime ziwiri zosinthasintha zotsutsana zomwe zimakwanitsa mpaka 83% ya kunjenjemera kwachiwiri. Zida zolimbitsa pamphepete mwa crankshaft zimayendetsa imodzi mwama shaft shaft, yomwe imayendetsanso inayo. Kupanga kwamano awiri (lumo) kumatsimikizira kutengapo gawo koyenera komanso kosalala kwa mano, ndipo kusapezeka kwa unyolo wamagalimoto kumachotsa chiopsezo chobvutikira. Pambuyo pofufuza mwatsatanetsatane, mayendedwe amanja amasankhidwa kuposa mayendedwe olumikizira migodi kuti achepetse phokoso ndi kugwedera komanso kulemera.

Mapangidwe a sump nawonso ndi atsopano. Njira yothetsera vutoli tsopano yasinthidwa ndi mapangidwe awiri pomwe pepala lazitsulo limamangiriridwa kumtunda wapamwamba wa zotayidwa pamwamba. Phokoso ndi magwiridwe antchito zimalimbikitsidwanso ndi kuyerekezera kwamitundu yambiri kwamkati ndi kunja kwa nthiti za magawo awiriwo.

Njira zina zomangamanga zochepetsera phokoso ndi monga:

ma jekeseni okhathamira kuti achepetse kuyaka kosawotchera popanda kuchepetsa mafuta; cholinga kuganizira za lamayimbidwe makhalidwe a nthiti mu pulasitala chitsulo yamphamvu; Kuyanjanitsa kwa ma compressor ndi mawilo amagetsi; kukonza bwino mano a nthawi ya lamba ndi zinthu zotchinjiriza kuti muchotse chikuto chake.

Chifukwa cha zisankho zapangidwezi, injini yatsopanoyo imapanga phokoso locheperako pantchito kuposa yomwe idapangidwirapo, ndipo ikangokhala chete imangokhala chete.

Sambani mipweya pogwiritsa ntchito Kuchepetsa Kuchepetsa Mavuto (SCR)

CDTI yatsopano ya 2,0 imatulutsa mpweya wofanana ndi mafuta, makamaka chifukwa cha Opel BlueInjection Selective Catalytic Reduction (SCR), yomwe ikugwirizana ndi Euro 6.

BlueInjection ndi ukadaulo wapambuyo womwe umachotsa ma nitrogen oxide (NOx) pamipweya yotulutsa mpweya. Kugwira ntchito kwa SCR kumachokera ku kugwiritsidwa ntchito kwa AdBlue® madzi opanda vuto, opangidwa ndi urea ndi madzi, omwe amalowetsedwa mumtsinje wotulutsa mpweya. Mwanjira iyi, yankho limawola ku ammonia, lomwe limatengedwa ndi misa yapadera yothandizira porous. Pochita nawo, ma nitrogen oxides (NOx), omwe ndi gawo la kuchuluka kwa zinthu zoyipa mumipweya yotulutsa mpweya yomwe imalowa mu chothandizira, amasinthidwa kukhala nayitrogeni weniweni ndi nthunzi wamadzi. Njira yothetsera AdBlue, yomwe imapezeka m'malo opangira ndalama m'malo ogula zinthu komanso m'malo operekera chithandizo cha Opel, imasungidwa mu thanki yomwe imatha kudzazidwa ngati kuli kofunikira kudzera pabowo lomwe lili pafupi ndi doko lodzaza.
