Kusintha kwatsopano kwa Volvo truck i-save system sikungochepetsa kuwononga mafuta, komanso kumachepetsa kwambiri mpweya woipa wa carbon dioxide, komanso kumapereka mwayi woyendetsa galimoto.I-save system imakweza ukadaulo wa injini, mapulogalamu owongolera ndi kapangidwe ka ndege.Kukweza konseko ndi cholinga chokwaniritsa cholinga chimodzi - kukulitsa mphamvu yamafuta.

Galimoto ya Volvo yakwezanso i-save system yonyamulidwa ndi Volvo FH, yomwe imawonetsetsa kukhathamiritsa kwa njira yoyatsira injini pofananiza jekeseni wamafuta, kompresa ndi camshaft ndi piston yake yatsopano ya wavy.Tekinoloje iyi sikuti imangochepetsa kulemera konse kwa injini, komanso imachepetsa kukangana kwamkati.Kuphatikiza pa kukweza turbocharger yogwira ntchito kwambiri ndi pampu yamafuta, zosefera za mpweya, mafuta ndi mafuta zakhala zikugwiranso ntchito bwino ndiukadaulo wawo wovomerezeka.

"Kuyambira ndi injini yabwino kwambiri, tadzipereka kukonza zinthu zambiri zofunika, zomwe zimaphatikizidwa kuti zithandizire kuyendetsa bwino mafuta.Zokwezerazi cholinga chake ndi kupeza mphamvu zochulukirapo kuchokera kudontho lililonse lamafuta. ”Helena AlSi, wachiwiri kwa purezidenti woyang'anira katundu wa Volvo truck powertrain, adatero.

Wokhazikika, wanzeru komanso wachangu

Pakatikati pa i-save system ndi injini ya d13tc - injini ya malita 13 ili ndi ukadaulo wa Volvo composite turbocharging.Injini imatha kusinthira kumayendedwe anthawi yayitali otsika kwambiri, kupangitsa kuyendetsa galimoto kukhala kokhazikika komanso phokoso lochepa.Injini ya d13tc imatha kugwira ntchito bwino pa liwiro lathunthu, ndipo liwiro loyenera ndi 900 mpaka 1300rpm.

Kuphatikiza pa kukweza kwa hardware, pulogalamu yatsopano yoyendetsera injini imawonjezeredwa, yomwe imagwira ntchito limodzi ndi kupititsa patsogolo kwa I-Shift.Kusintha kwanzeru kwaukadaulo wosinthira kumapangitsa galimotoyo kuyankha mwachangu komanso kuyendetsa bwino, zomwe sizimangowonjezera kuchuluka kwamafuta, komanso zikuwonetsa momwe amagwirira ntchito.

I-torque ndi pulogalamu yanzeru yowongolera mphamvu yamagetsi, yomwe imasanthula deta yamtunda munthawi yeniyeni kudzera munjira ya I-see cruise, kuti galimotoyo igwirizane ndi zomwe zikuchitika pamsewu, kuti zithandizire kuwongolera mafuta.Dongosolo la I-see limakulitsa mphamvu zamakinetic zamagalimoto oyenda kumadera amapiri kudzera muzambiri zenizeni zamisewu.I-torque engine control system imatha kuwongolera zida, torque ya injini ndi ma braking system.

"Kuti muchepetse kugwiritsa ntchito mafuta, galimotoyo imagwiritsa ntchito" eco "mode poyambira.Monga dalaivala, nthawi zonse mumatha kupeza mphamvu zofunikira, komanso mutha kupezanso kusintha kwa zida mwachangu komanso kuyankha kwa torque kuchokera pamakina otumizira. ”Helena AlSi anapitiriza.

Mapangidwe a aerodynamic amagalimoto amathandizira kwambiri kuchepetsa kugwiritsa ntchito mafuta panthawi yoyendetsa mtunda wautali.Magalimoto a Volvo apanga zosintha zambiri pamapangidwe aaerodynamic, monga malo ocheperako kutsogolo kwa kabati ndi zitseko zazitali.

Kuyambira pomwe i-save system idatuluka mu 2019, yakhala ikuthandizira makasitomala agalimoto a Volvo bwino.Kuti mubwezere chikondi cha makasitomala, injini yatsopano ya 420hp yawonjezedwa ku injini zam'mbuyo za 460hp ndi 500hp.Ma injini onse ndi hvo100 certified (hvo100 ndi zongowonjezwdwa mafuta mu mawonekedwe a hydrogenated masamba mafuta).

Magalimoto a Volvo FH, FM ndi FMX okhala ndi injini za 11 kapena 13 litre Euro 6 nawonso akwezedwa kuti apititse patsogolo kuyendetsa bwino kwamafuta.

 
Pitani ku magalimoto osakhala mafuta

Cholinga cha Volvo Trucks ndichakuti magalimoto amagetsi azitenga 50% yazogulitsa zonse pofika chaka cha 2030, koma injini zoyatsira mkati zipitiliza kugwira ntchito.Dongosolo la i-save lomwe langosinthidwa kumene limapereka mphamvu yabwino yamafuta ndikuwonetsetsa kuchepetsa kutulutsa mpweya wa carbon dioxide.

 
"Tadzipereka kutsata mgwirizano wanyengo wa Paris ndipo tidzachepetsa mosasunthika kutulutsa mpweya wa kaboni mumayendedwe onyamula katundu mumsewu.M’kupita kwa nthaŵi, ngakhale tikudziwa kuti kuyenda kwa magetsi ndi njira yofunika kwambiri yochepetsera mpweya wa carbon, injini zoyaka zoyaka mkati mwazopatsa mphamvu zidzachitanso mbali yofunika kwambiri m’zaka zingapo zikubwerazi.”Helena AlSi anamaliza.
