Zodzikongoletsera za dizilo. Mavuto omwe angawononge injini

Swirl flaps ndi yankho lomwe limagwiritsidwa ntchito mumainjini ambiri a dizilo wamba. Kusokonekera kwa mpweya komwe kumapanga m'dongosolo lolowera patsogolo pa mavavu olowetsamo kumathandiza kuti kuyaka kwapang'onopang'ono. Chotsatira chake, mpweya wotuluka uyenera kukhala waukhondo, wokhala ndi ma nitrogen oxide otsika.  

Chiphunzitso chochuluka, chomwe chimafanana ndi chenicheni, ngati chirichonse mu injini chinali chothandiza komanso choyera. Monga lamulo, ma valve okwera pa oxis amasintha unsembe wawo malinga ndi liwiro la injini - pamunsi amatsekedwa kuti mpweya wochepa ulowe muzitsulo, koma amapotozedwa moyenerera, ndipo pamwamba ayenera kukhala otseguka. kotero kuti injini "imapuma" mokwanira. Tsoka ilo, chipangizochi chimagwira ntchito m'mikhalidwe yovuta kwambiri ndipo chifukwa chake chimakhala cholephera. Nthawi zambiri amakhala ndi kutsekereza mavavu chifukwa cha mwaye wosonkhanitsidwa kapena ngakhale kuwalekanitsa ndi zomangira.

Chizindikiro chofala cha kulephera kwa chipwirikiti kukhazikika pamalo otseguka, "pansi" ya injini ndi yofooka kwambiri, i.e. mpaka turbocharger ifika pamphamvu yowonjezereka kwambiri. Zotsatira zake kuchuluka kwa mwaye mu mpweya wotulutsa mpweyaNdipo akabwerera ku chakudya kudzera mu valavu ya EGR, zowononga zambiri zimadziunjikira mu dongosolo la kudya. Choncho, wosonkhanitsa - wodetsedwa kale - amakhala wakuda ngakhale mofulumira. 

Ma throttles akatsekeka, mutha kutsika mphamvu pama RPM apamwamba chifukwa mpweya wocheperako ukukokedwa mu masilindala. Ndiye mlingo wa mwaye mu dongosolo umawonjezekanso. Tsoka ilo, kuwonjezeka kwa utsi wotulutsa utsi, mosasamala kanthu za liwiro, kumakhala ndi zotsatira zake zina mwa mawonekedwe othamangitsidwa. Exhaust System kuvala (DPF fyuluta) ndi turbocharger. 

Monga lamulo, zizindikiro zotere zimawonekera pambuyo pa kuthamanga kwa 100-2005 km. Km, ngakhale opanga injini potsiriza anazindikira vuto ndi kusintha mapangidwe ambiri pambuyo 90. vuto lomwe linakula kwambiri pamene injini za dizilo za njanji zoyambilira chakumapeto kwa zaka za m’ma 47 zinayamba kulephera kwambiri. Izi ndizochitika zomwe nthawi zambiri zimayamba pamene ziwombankhanga, chifukwa cha kukwera kosauka muzobweza zambiri, zidasweka ndikugwa mozama mu dongosolo lakumwa, kugundana ndi valavu yolowera, ndipo ngakhale zitatha kusweka zidatha mu silinda. Kumeneko nthawi zambiri ankawonongeka kwambiri. Ma injini omwe anali pachiwopsezo chachikulu cha izi anali M57 ndi M1.9 kuchokera ku BMW ndi 2.4 ndi 1.9 JTD kuchokera ku Fiat ndi mapasa a CDTi ochokera ku Opel.

Akatswiri amalangiza - chotsani zophimba!

Ngakhale izi zikuwoneka ngati zotsutsana chifukwa cha kuyera kwa mpweya wotulutsa mpweya, makaniko omwe amagwira ntchito ndi injini za dizilo tsiku lililonse pafupifupi amavomereza kuti achotse zotchinga. Zimaphatikizapo kugwiritsa ntchito mapulagi pamalo omwe amayikirako ndi / kapena kuletsa ntchito yawo mu chowongolera chamoto. Akatswiri a dizilo otchuka amatsimikizira zimenezo kusowa kwa ma swirl flaps sikukhudza ntchito ndi mawonekedwe a injini. Izi ndizosangalatsa chifukwa kutseka zotchingira pamalo otseguka kumakhudza magawo otsika a rpm, kotero kupezeka kwawo m'mikhalidwe iyi kumawoneka kofunikira. Chifukwa chake, m'mainjini ena, ndikuchotsa zotchingira, tikulimbikitsidwa kukonzanso mamapu muzowongolera.

Kuphatikiza apo, ma dizilo okhala ndi ma mileage apamwamba amakhala ndi kusintha kwabwino kwa mpweya wotulutsa (utsi wochepa) mukachotsa zoziziritsa kukhosi. Ichi ndi chimodzi mwa njira zingapo zomwe zimagwiritsidwa ntchito mu injini zamakono za dizilo zomwe zimakhudza khalidwe la gasi, koma mpaka kufika pamtunda wina (otsika mtunda). M'kupita kwa nthawi, injini zopanda njira zokhazikika zimangoyenda bwino ndikuchita bwino.

Kapena mwina m'malo?

Pafupifupi zaka khumi zapitazo, uku kunali kukonza kokwera mtengo chifukwa zochulukira zimaperekedwa ngati magawo afakitale pamtengo pafupifupi PLN 2000 iliyonse. Pa injini za V6, nthawi zina ziwiri zimafunika kusinthidwa. Masiku ano, makampani ena amapereka kukonzanso kwa osonkhanitsa kapena kusintha kwa mazana angapo a zł, ndipo ngakhale m'malo mwa damper (otchedwa zida za regeneration) awonekera pamsika. Mitengo yawo ndi yaying'ono, pafupifupi 100-300 zloty pa seti.

Izi zimapangitsa kukonza ma dampers (kusinthika kwawo kapena kusinthidwa kwamitundu yonse) kusakhalenso okwera mtengo kwambiri, motero ndikofunikira. Komabe, palibe umboni wosonyeza kuti kukhazikitsa zida zatsopano, zogwirira ntchito pa injini yomwe ili ndi mtunda wautali, choncho nthawi zambiri imakhala yodetsedwa kale mkati, idzawongolera njira yoyatsira ndipo motero ukhondo wa mpweya wotulutsa mpweya. Komabe, kukhala ndi injini yathunthu ya fakitale ndikofunikira ngati pachifukwa ichi. Monga momwe adafunira mlengi wake.
