Injini yamagalimoto ndiye gwero lamphamvu komanso gawo lalikulu lagalimoto. Ndi kukweza kosalekeza kwagalimoto, magwiridwe antchito a injini amakhalanso bwino nthawi zonse. Cholinga chake ndikuwonjezera mphamvu zamagetsi ndikuchepetsa kugwiritsa ntchito mafuta komanso zowononga zowononga. Tekinoloje zambiri zapamwamba zamainjini, monga ukadaulo wa silinda yotseka. Ndikukhulupirira kuti okwera mosamala adzapeza kuti pali VVT, VVT-i, VVT-W, DVVT, CVVT, etc. pa injini ya galimoto yawo. Ndiye zizindikiro izi zikutanthauza chiyani? Madalaivala akale sangadziwe, anthu ambiri sangadziwe kusiyana kwake!
Izi zizindikiro pa injini galimoto mosakayikira zizindikiro za ntchito inayake ya injini, koma kwenikweni iwo si osiyana kwambiri, monga dongosolo galimoto magudumu anayi. Dongosolo la magudumu a Audi la Audi limatchedwa Quattro, Subaru's four-wheel drive system amatchedwa DCCD, Mitsubishi's four-wheel drive system imatchedwa S-AWC, ndi zina zotero. N'chimodzimodzinso ndi logos injini tatchulazi. Onse pamodzi amatchedwa VVT, njira yosinthira valavu ya injini yamagalimoto, yomwe imangokhala mawonekedwe a valve a injini.
Bodza: Anthu ambiri amaganiza kuti kulowetsa injini ndikosavuta, makamaka injini ya turbo ndikuwonjezera zida za turbo. Mpweya ukhoza kuwonedwa kulikonse, koma mafuta ndi ochepa, choncho anthu ambiri amaganiza kuti kulowetsa injini kumakhala kosavuta, koma kwenikweni, kulowetsedwa kwa injini kumakhala kovuta. Kupanda kutero, pangakhale bwanji mawonekedwe ogawa omwe tawatchulawa?
Monga tonse tikudziwa, silinda ya injini imapanga mphamvu poyatsira ndi kupondereza mafuta ndi mpweya. Ndi mafuta ochuluka bwanji omwe amaperekedwa mu silinda kudzera mu makina opangira mafuta agalimoto, ndipo mpweya wake ndi wochuluka bwanji? Injini yolakalaka mwachilengedwe imalowa mwachilengedwe kudzera mukuyenda kwa mpweya, koma mphamvu yamagetsi si yabwino. Kuti athetse vutoli, turbocharged injini anabadwa. Pambuyo poyika chipangizo cha turbo-aspirated, mphamvuyo yakhala yabwino kwambiri. Mmodzi mwa awiriwa ndi wongokhala. Pokoka mpweya, mmodzi ndi yogwira inhalation.
Zitha kuwoneka kuchokera pamwambapa kuti mpweya umagwira ntchito yofunika kwambiri pamagetsi a galimoto, ndipo kuwonjezera kwa VVT ya injini ya galimoto mosakayika kudzabweretsa ntchitoyo pamlingo wapamwamba. Mwa kulamulira dongosolo la ntchito ya masilindala a injini, madoko olowera ndi kutulutsa a silinda iliyonse amatsegulidwa ndikutsekedwa pafupipafupi kuti mpweya wambiri ulowe mu silinda ndikusakanikirana ndi mafuta, kotero kuti injiniyo imatha kuchita bwino kwambiri, kotero kuti in-cylinder Mukalowa mpweya wambiri, galimoto yanu imachita bwino.
Injini VVT-i, VVT-W, DVVT, CVVT ndi zizindikiro zina kwenikweni ndi valavu limagwirira injini. Zomwe zimatchedwa kusinthasintha kwa nthawi ya valve ndi kukweza ukadaulo kumatanthauza kuti mawonekedwe a valve ya injini ndi kukweza valavu zimatha kusiyana ndi injini. Ukadaulo womwe umasintha nthawi iliyonse chifukwa cha kusintha kwa liwiro komanso magwiridwe antchito ali ngati anthufe timadya panthawi yoikika. Ngati zimanenedwa kuti zimatsegulidwa pasadakhale nthawi ya chakudya isanakwane, ndipo chakudya chimatsegulidwa pasadakhale, zitha kumveka bwino kuti valavu yolowera imatsegulidwa kale, ndipo Kuti muthane ndi zolimbitsa thupi pambuyo pake, idyani zakudya zambiri, kotero kuchedwetsa nthawi yosiya kudya ndikofanana ndi kutseka kochedwa kwa silinda. Atadziwa zimenezi, dalaivala wakale yemwe wakhala akuyendetsa galimoto kwa zaka khumi akuchita manyazi, ndipo galimoto yomwe yakhala ikuyendetsedwa kwa zaka zoposa khumi sichidziwa chizindikiro, chomwe chiridi manyazi.
Chifukwa chomwe iwo amasiyana ndi chakuti opanga magalimoto osiyanasiyana ali ndi malingaliro osiyanasiyana ndi machitidwe a makina osinthasintha a nthawi ya injini, kotero pali zochitika zosiyanasiyana zomwe maluwa zana amatsutsana, kotero pali VVT, VVT-i, VVT-W , DVVT, CVVT. Mwachindunji, VVT imatanthawuza kusinthasintha kwa nthawi ya valve, DVVT imatanthawuza kulowetsa ndi kutulutsa mpweya wa valve wapawiri, CVVT imatanthawuza kusinthasintha kwa nthawi ya valve, ndipo VVT-i imatanthawuza dongosolo la Toyota lanzeru losintha nthawi. VVT-iW imatanthawuza njira ya Toyota yanzeru yosinthira valavu yomwe imatha kuzindikira kuzungulira kwa Atkinson. Iwo ali kwambiri wothandiza zotsatira pa ntchito ya injini ndi kumwa mafuta a galimoto.
(Chithunzi ndi zolembazo zikuchokera pa intaneti, ngati pali zophwanya, chonde lemberani kuti muchotse)
