Mafuta ndi jekeseni mwachindunji
Magalimoto ochulukirachulukira pamsika wathu ali ndi injini zamafuta zokhala ndi jekeseni mwachindunji. Kodi ndi oyenera kugula?
Injini zokhala ndi jekeseni mwachindunji wa petulo ziyenera kukhala zotsika mtengo kuposa zamakono. Mwachidziwitso, ndalama zomwe zimagwiritsidwa ntchito pamafuta ziyenera kukhala pafupifupi 10%. Kwa opanga ma automaker, iyi ndi gawo lofunikira, ndipo pafupifupi aliyense akuchita kafukufuku ndi magetsi otere.
Chodetsa nkhaŵa cha Volkswagen chinayang'ana kwambiri pa jekeseni wachindunji, makamaka m'malo mwa injini zachikhalidwe ndi mayunitsi a jekeseni, otchedwa FSI. Msika wathu, injini za FSI zitha kupezeka ku Skoda, Volkswagen, Audi ndi Mipando. Alfa Romeo amafotokoza injini monga JTS, zomwe zimapezekanso kwa ife. Magawo amphamvu oterowo 
imaperekanso Toyota ndi Lexus.
Lingaliro la jekeseni wolunjika wa petulo ndikupanga osakaniza mwachindunji muchipinda choyaka moto. Kuti muchite izi, jekeseni wamagetsi amayikidwa m'chipinda choyaka moto, ndipo mpweya wokhawo umaperekedwa kudzera mu valve yolowera. Mafuta amabayidwa mopanikizika kwambiri kuchokera ku 50 mpaka 120 bar, opangidwa ndi mpope wapadera.
Kutengera kuchuluka kwa katundu wa injini, imagwira ntchito m'njira ziwiri. Pansi pa katundu wopepuka, monga idling kapena kuyendetsa pa liwiro lokhazikika pamtunda wosalala, wosalala, wosakanikirana wowonda amadyetsedwa mmenemo. Pali mafuta ocheperako pakusakaniza kowonda, ndipo izi ndizo ndalama zomwe zalengezedwa.
Komabe, pogwira ntchito pamtunda wapamwamba (mwachitsanzo, kuthamanga, kuyendetsa mtunda, kukoka ngolo), komanso ngakhale pa liwiro la 3000 rpm, injini imawotcha osakaniza stoichiometric, monga injini wamba.
Tidawona momwe zimawonekera poyendetsa VW Golf yokhala ndi injini ya 1,6 FSI yokhala ndi 115 hp. Poyendetsa mumsewu waukulu ndi katundu wochepa pa injini, galimotoyo inkadya pafupifupi malita 5,5 a mafuta pa 100 km. Poyendetsa mwamphamvu pamsewu "wabwinobwino", magalimoto odutsa ndi magalimoto ocheperako, Gofu idadya malita 10 pa 100 km. Titabwerera m’galimoto imodzimodziyo, tinayendetsa galimoto mwakachetechete, ndipo pa mtunda wa makilomita 5,8 tinadya pafupifupi malita 100.
Tidapeza zotsatira zofananira poyendetsa Skoda Octavia ndi Toyota Avensis.
Njira yoyendetsera galimoto imagwira ntchito yofunika kwambiri pakugwiritsa ntchito mafuta a injini ya jekeseni wolunjika wa petulo. Apa ndipamene kuyendetsa mowonda ndikofunikira. Madalaivala omwe amakonda kuyendetsa movutikira sangapindule ndi njira yachuma yoyendetsera injini. Zikatere, zingakhale bwino kugula zotsika mtengo, zachikhalidwe.
