Kub V , los yog V Kub - nws suab zoo dua hauv lus Askiv, tsis muaj qhov tsis ntseeg - yog lub npe uas tau pom kev pom tom qab tso tawm ntawm Mercedes-AMG GT, nruab nrog M178, tag nrho cov muaj zog 4000cc twin-turbo V8 los ntawm Affalterbach.
Tab sis vim li cas Hot V? Nws tsis muaj dab tsi ua nrog rau cov npe ntawm lub cav qhov zoo, siv cov lus Askiv hais lus. Qhov tseeb, nws yog ib qho kev siv rau ib qho tshwj xeeb ntawm kev tsim cov cav nrog V-lub tog raj kheej - txawm tias roj av lossis diesel - qhov twg, tsis zoo li lwm yam Vs, cov chaw nres nkoj tso tawm (hauv lub taub hau cav) taw qhia rau sab hauv. lub V hloov mus rau sab nraud, uas tso cai rau tso lub turbochargers ntawm ob lub tog raj kheej lub tog raj kheej thiab tsis nyob rau sab nraud ntawm lawv.
Vim li cas thiaj siv cov tshuaj no? Muaj peb qhov laj thawj zoo heev thiab cia peb mus rau lawv kom ntxaws ntxiv.
Kub
Koj yuav pom qhov twg lub npe Kub los ntawm. Turbochargers yog siv los ntawm cov pa roj, nyob ntawm seb lawv tig kom zoo. Cov pa hluav taws xob xav tau kub heev - kub ntau, siab dua, yog li ntawd, ntau ceev -; Qhov no yog tib txoj kev los xyuas kom meej tias lub turbine sai sai mus txog nws qhov optimum rotational ceev.
Yog tias cov roj cua txias, poob siab, qhov ua tau zoo ntawm lub turbo kuj txo, txawm tias nce lub sij hawm kom txog thaum lub turbo tig kom zoo, lossis tsis ncav cuag qhov zoo tshaj plaws kev sib hloov ceev. Hauv lwm lo lus, peb xav muab cov turbos tso rau hauv qhov chaw kub thiab ze rau qhov chaw nres nkoj tso pa.
Thiab nrog cov pa tso pa tawm taw qhia rau sab hauv ntawm V, thiab cov turbos tso nruab nrab ntawm ob lub tog raj kheej lub tog raj kheej, lawv txawm nyob rau hauv "kub qhov chaw", uas yog, nyob rau hauv lub engine cheeb tsam uas emanates cua sov tshaj plaws thiab ntau ze rau lub lub qhov rooj tso cov yeeb nkab - uas ua rau cov kav dej tsawg dua kom nqa cov pa pa tawm, thiab yog li ntawd tsawg dua qhov kub thaum taug kev los ntawm lawv.
Tsis tas li ntawd cov catalytic converters nyob rau hauv lub V, es tsis txhob ntawm lawv li ib txwm txoj hauj lwm nyob rau hauv lub tsheb, raws li cov no ua hauj lwm zoo tshaj plaws thaum lawv kub heev.
Ntim
Raws li koj tuaj yeem xav, nrog txhua qhov chaw zoo nyob, ua rau lub cav ntxaib-turbo V ntau dua li ib qho nrog turbos tso rau sab nraum V . Raws li nws yog ntau compact, nws kuj yog yooj yim rau muab tso rau hauv ib tug ntau ntawm cov qauv. Noj M178 ntawm Mercedes-AMG GT, peb tuaj yeem pom ntau yam ntawm nws - M176 thiab M177 - hauv ntau tus qauv, txawm tias nyob hauv C-Class tsawg tshaj plaws.
Lwm qhov zoo dua yog kev tswj hwm ntawm lub cav nws tus kheej hauv lub compartment destined rau nws. Cov pawg muaj ntau qhov chaw, ua rau lawv cov viav vias tuaj yeem kwv yees ntau dua.
Thawj Kub V
Mercedes-AMG tau ua tus Hot V npe nrov, tab sis lawv tsis yog thawj tus siv cov tshuaj no. Nws cov neeg sib tw BMW tau nthuav tawm nws xyoo ua ntej - nws yog thawj zaug siv cov tshuaj no rau lub tsheb tsim khoom. Lub cav N63, twin-turbo V8, tau tshwm sim hauv xyoo 2008 hauv BMW X6 xDrive50i, thiab yuav los muab ntau lub BMWs suav nrog X5M, X6M lossis M5, qhov twg N63 tau dhau los ua S63, tom qab tau dhau los ntawm M. Tab sis qhov no Ib tug layout ntawm lub turbos nyob rau hauv lub V yog thawj zaug pom nyob rau hauv kev sib tw, thiab ces nyob rau hauv lub premier chav kawm ntawv, Formula 1, nyob rau hauv 1981. Ferrari 126C yog thawj zaug txais yuav qhov kev daws teeb meem no. Lub tsheb tau nruab nrog V6 ntawm 120º nrog ob lub turbos thiab tsuas yog 1.5 l, muaj peev xwm xa tau ntau dua 570 hp.
Turbocharger tswj
Qhov sib thooj ntawm cov turbochargers mus rau qhov chaw nres nkoj tawm, kuj tso cai rau kev tswj kom meej dua ntawm cov no. V-engines muaj lawv tus kheej ignition ib ntus, uas ua rau kev tswj lub turbocharger nyuaj, raws li lub rotor poob thiab nce ceev irregularly.
Nyob rau hauv ib tug pa twin-turbo V-engine, kom txo tau tus yam ntxwv no, ua kom ceev variation ntau kwv yees, yuav tsum tau ntxiv cov kav dej ntau. Nyob rau hauv ib tug kub V, ntawm qhov tod tes, qhov sib npaug ntawm lub cav thiab lub turbos yog qhov zoo dua, vim yog qhov sib thooj ntawm tag nrho cov khoom, uas ua rau cov lus teb meej dua thiab sharpening throttle, uas yog reflected nyob rau hauv lub tsheb tswj.
Qhov Kub Vs yog, yog li ntawd, ib qho kev txiav txim siab mus rau "tsis pom" turbos, uas yog, peb yuav mus txog qhov chaw uas qhov sib txawv ntawm incisive teb thiab linearity ntawm ib txwm aspirated engine thiab ib tug turbocharged yuav imperceptible. Nyob deb ntawm cov hnub ntawm cov tshuab zoo li Porsche 930 Turbo lossis Ferrari F40, qhov twg nws yog "tsis muaj dab tsi, tsis muaj dab tsi, tsis muaj dab tsi… TUUUUUUDO!" - tsis yog lawv tsis ntshaw vim li ntawd...
