ACT cylinder deactivation ntchito. Kodi zimagwira ntchito bwanji ndipo zimapereka chiyani muzochita?
Kugwiritsa ntchito mafuta ndi chimodzi mwazinthu zofunika kwambiri posankha galimoto kwa wogula. Choncho, opanga amagwiritsa ntchito njira zosiyanasiyana zochepetsera mafuta. Chimodzi mwa izo ndi ntchito ya ACT, yomwe imalepheretsa theka la masilindala a injini.
Si chinsinsi kwa madalaivala ambiri kuti injini ya galimoto imafuna mphamvu zambiri kuti iyambitse galimotoyo komanso ikafunika kuthamanga mwamphamvu, monga pamene ikudutsa. Kumbali ina, poyendetsa pa liwiro lokhazikika, mphamvu yomwe injiniyo imatchula nthawi zambiri sagwiritsidwa ntchito. M'malo mwake, mafutawa amagwiritsidwa ntchito kupatsa mphamvu ma silinda. Chifukwa chake, okonzawo adawona kuti izi ndi zowononga ndipo adanenanso kuti ngati sikufunika mphamvu zonse zagalimoto, zimitsani theka la masilindala.
Mutha kuganiza kuti malingaliro otere akugwiritsidwa ntchito m'magalimoto okwera mtengo okhala ndi mayunitsi akulu. Palibe chomwe chingakhale cholakwika kwambiri. Mayankho amtunduwu amapezekanso m'magalimoto kwa makasitomala osiyanasiyana, mwachitsanzo, ku Skoda.
Mbali iyi ya silinda yothimitsa imapezeka mu injini ya petulo ya 1.5 TSI 150 hp, yomwe ingasankhidwe ku Skoda Octavia (saloon and station wagon) ndi Skoda Karoq, onse otumiza pamanja ndi apawiri-clutch.
Yankho lomwe likugwiritsidwa ntchito mu injini iyi limatchedwa Active Cylinder Technology - ACT. Kutengera kuchuluka kwa injini, ACT imatsekereza ma silinda awiri mwa anayi kuti achepetse kugwiritsa ntchito mafuta. Masilinda awiri amazimitsidwa ngati palibe chifukwa chowonjezera mphamvu ya injini, i.e. pakuyenda movutikira pa liwiro lotsika.
M'pofunikanso kuwonjezera kuti kufala zodziwikiratu kale ntchito zaka zingapo zapitazo mu injini 1.4 TSI ndi mphamvu 150 HP, amene anaikidwa mu Skoda Octavia. Pambuyo pake, gawoli linayamba kukhazikitsidwa pansi pazithunzi za Superb ndi Kodiaq.
Pokhudzana ndi injini ya 1.4 TSI, zosintha zingapo zapangidwa ku 1.5 TSI unit. Wopangayo akuti sitiroko ya silinda imachulukitsidwa ndi 5,9 mm ndikusunga mphamvu yomweyo - 150 hp. Komabe, poyerekeza ndi injini ya 1.4 TSI, injini ya 1.5 TSI imakhala yosinthika kwambiri ndipo imayankha mofulumira ku accelerator pedal.
Komanso, choziziritsa kukhosi, ndiko kuti, choziziritsa mpweya choponderezedwa ndi turbocharger (kukakamiza mpweya wochulukirapo kulowa mu masilindala ndikuwonjezera mphamvu ya injini), idapangidwa kuti iziziziritsa katundu woponderezedwa mpaka kutentha kwa madigiri 15 okha. kuposa injini. kutentha kozungulira. Chotsatira chake, mpweya wochuluka umalowa m'chipinda choyaka moto, zomwe zimapangitsa kuti galimoto ikhale yabwino.
Kuthamanga kwa jekeseni wa petulo kwawonjezekanso kuchoka pa 200 mpaka 350 bar, zomwe zathandizira kuyaka.
Kayendetsedwe ka makina a injini kwawongoleredwanso. Mwachitsanzo, chigawo chachikulu cha crankshaft chimakutidwa ndi polima, ndipo masilindala amapangidwa mwapadera kuti achepetse kugundana injini ikazizira.
