Dieselgate itatha kuphimba ma Diesel mumtambo wakuda - timati "motsimikizika", chifukwa kwenikweni, mapeto ake anali akutsutsana kale modzichepetsa - tsopano m'malo oyenera akufunika. Mokonda kapena ayi, chowonadi ndi chakuti injini za dizilo zinali ndipo zikupitilizabe kukhala zosankha za ogula ambiri. Ndipo ayi, sikuli ku Portugal kokha… Tengani chitsanzo ichi.
Cholowa m'malo: amafuna!
Padzapita nthawi kuti magetsi akhale "wamba" pakampani yamagalimoto - akuti mu 2025 gawo la magalimoto amagetsi a 100% akadali pafupi ndi 10%, zomwe sizili zambiri.Choncho, mpaka kufika kwa "zachilendo" zatsopanozi, yankho likufunika lomwe limapereka chuma chogwiritsira ntchito komanso kuchuluka kwa mpweya wa Dizilo pamtengo wogula injini zamafuta.
Njira ina yotani imeneyi?
Chodabwitsa n'chakuti, Volkswagen, mtundu umene unali pachimake cha chivomezi chotulutsa mpweya, womwe umabwera ndi njira ina kuposa Dizilo. Malinga ndi mtundu waku Germany, njira ina ikhoza kukhala injini yanu yatsopano ya B-cycle. Chifukwa chake ndikuwonjezera mtundu wina wozungulira kwa omwe alipo kale mu injini zamafuta: Otto, Atkinson ndi Miller.
Zozungulira ndi zina zambiri
Chodziwika bwino ndi kuzungulira kwa Otto, yankho lobwerezabwereza kwambiri mumakampani amagalimoto. Kuzungulira kwa Atkinson ndi Miller kumakhala kothandiza kwambiri pakuwononga magwiridwe antchito ena.
Kupindula (mwachangu) ndi kutayika (pantchito) chifukwa cha nthawi yotsegula ya valve yolowera mu gawo loponderezedwa. Nthawi yotsegulirayi imayambitsa gawo loponderezedwa lomwe ndi lalifupi kuposa gawo lokulitsa.
Gawo la katundu mu gawo loponderezedwa limatulutsidwa ndi valve yolowera yomwe ikadali yotseguka. pisitoni motero amapeza zochepa kukana kwa psinjika mpweya - chifukwa dzuwa mwachindunji ndi otsika, ndiko kuti, kumabweretsa zochepa kavalo ndi Nm. Apa ndi pamene Miller mkombero, amatchedwanso «five sitiroko» injini, imalowa. yomwe, ikagwiritsa ntchito kuwotcha kwambiri, imabwezeretsa mtengo wotayikawu kuchipinda choyaka moto.
Masiku ano, chifukwa chakuchulukirachulukira kwa njira yonse yoyatsira, ngakhale ma injini ozungulira a Otto amatha kutengera ma cycle a Atkinson pamene katundu ali wochepa (potero akuwonjezera mphamvu zawo).
Ndiye cycle B imagwira ntchito bwanji?
Kwenikweni, kuzungulira B ndikusinthika kwa kuzungulira kwa Miller. Kuzungulira kwa Miller kumatseka ma valve omwe amadya atangotsala pang'ono kutha kwa sitiroko. Kuzungulira kwa B kumasiyana ndi kuzungulira kwa Miller chifukwa kumatseka ma valve olowera kale. Zotsatira zake zimakhala zotalikirapo, kuyaka bwino komanso kuthamanga kwa mpweya kumagasi omwe amamwa, zomwe zimapangitsa kuti mafuta azikhala bwino.
Chimodzi mwazabwino za B-mkombero watsopanowu ndikutha kusinthira kumayendedwe a Otto pomwe mphamvu yayikulu ikufunika, kubwerera kumayendedwe abwino kwambiri a B pamikhalidwe yogwiritsira ntchito. Izi ndizotheka chifukwa cha kusuntha kwa axial kwa camshaft - yomwe ili ndi makamera awiri pa valve iliyonse - kulola kuti nthawi zotsegulira za ma valve olowera zisinthidwe pazigawo zonse.
Poyambira
Injini ya EA888 inali poyambira yankho ili. Zodziwika kale kuchokera kuzinthu zina za gulu la Germany, ndi injini ya turbo 2.0 l yokhala ndi masilinda anayi pamzere. injini Izi makamaka kusinthidwa pa mlingo mutu (analandira camshafts latsopano ndi mavavu) ntchito molingana ndi magawo mkombero watsopano. Kusintha kumeneku kunakakamizanso kukonzanso ma pistoni, zigawo ndi chipinda choyaka moto.Pofuna kubweza gawo lalifupi la psinjika, Volkswagen idakweza chiŵerengero cha kuponderezedwa kwa 11.7: 1, mtengo womwe sunachitikepo wa injini yodzaza kwambiri, zomwe zimatsimikizira kulimbitsa kwa zigawo zina. Ngakhale EA888 yomwe ilipo sikudutsa 9.6:1. Jekeseni wachindunji adawonanso kuthamanga kwake, komwe kukufikira mipiringidzo 250.
Monga kusinthika kwa EA888, m'badwo wachitatu wa banja la injiniyi umadziwika kuti EA888 Gen. 3B.
tiyeni tipite ku manambala
EA888 B imasunga ma silinda anayi onse pamzere ndi 2.0 l wa mphamvu, komanso kugwiritsa ntchito turbo. Imapereka mozungulira 184 hp pakati pa 4400 ndi 6000 rpm ndi 300 Nm ya torque pakati pa 1600 ndi 3940 rpm. . Injini iyi poyamba ikufuna kusintha 1.8 TSI yomwe imakhala ndi mitundu yambiri yamitundu yaku Germany yomwe imagulitsidwa pamsika waku North America.
Kuchepetsa kuti mugwire bwino ntchito? Kapena kumuwona.
Zikhala mpaka zatsopano Volkswagen Tiguan injini yatsopano ku USA. Malingana ndi chizindikirocho, 2.0 yatsopano idzalola kuti machitidwe abwino azichita bwino komanso kuchepetsa kuchepa kwa mpweya ndi mpweya poyerekeza ndi 1.8 yomwe imasiya kugwira ntchito.
Pakalipano, palibe deta yovomerezeka yokhudza kumwa. Koma mtunduwo ukuyerekeza kuchepetsa kumwa pafupifupi 8%, chiwerengero chomwe chingawongoleredwe bwino ndikukula kwa B-cycle yatsopanoyi.
