Cav: Nissan VK45DD, VK45DE
Txheem
Kev txhawj xeeb "Nissan" yog nto moo rau kev tsim cov peev nyiaj, tab sis cov khoom zoo heev. Txawm li cas los xij, nyob rau hauv cov qauv kab ntawm cov chaw tsim khoom kuj tseem kim, cov thawj coj lossis kev ua si tsheb.
Rau cov qauv zoo li no, Japanese tus kheej tsim thiab tsim cov motors uas muaj kev ua haujlwm zoo thiab kev ntseeg siab tshaj plaws. Niaj hnub no peb yuav tham txog ob lub cav Nissan muaj zog heev - VK45DD thiab VK45DE. Nyeem ntxiv txog lub tswv yim, keeb kwm ntawm lawv cov creation thiab cov yam ntxwv ntawm kev ua haujlwm hauv qab no.
Hais txog kev tsim thiab tsim cov motors
Lub ICEs tau txiav txim siab hnub no nyob rau hauv lub ntsej muag ntawm VK45DD thiab VK45DE nkag mus rau Nissan conveyors hauv 2001. Lawv tau tsim rau 9 xyoo, uas yog, nyob rau hauv 2010, lub creation ntawm engine ceased. VK45DD thiab VK45DE hloov cov chav nyob tsis tu ncua rau cov neeg sawv cev thiab cov qauv kev ua kis las ntawm kev txhawj xeeb. Kom meej meej, cov chav nyob tau hloov VH41DD/E thiab VH45DD/E. Lawv tau nruab rau hauv Infiniti Q45, Nissan Fuga, Thawj Tswj Hwm thiab Cima.
VK45DD thiab VK45DE yog 8-lub tog raj kheej, roj av cav nrog lub zog tsim thiab muaj zog txaus. Variations ntawm cav nrog ib tug ntim ntawm 4,5 litres thiab 280-340 "nees" tawm nyob rau hauv lub kawg tso tawm. Qhov sib txawv ntawm VK45DD thiab VK45DE dag nyob rau hauv ntau yam ntawm lawv cov kev tsim kho, uas yog:
- Compression ratio - rau VK45DD nws yog 11, thiab rau VK45DE nws yog nyob rau theem ntawm 10,5.
- Lub tshuab hluav taws xob - VK45DD muaj cov khoom noj ncaj qha nyob rau hauv kev tswj hwm ntawm ib chav tshwj xeeb, thaum VK45DE siv ntau lub ntsiab lus roj txhaj rau hauv lub tog raj kheej (ib qho tshuaj txhaj tshuaj).
Nyob rau hauv lwm yam, lub VK45DD thiab VK45DE yog kiag li zoo tib yam motors ua nyob rau hauv lub hauv paus ntawm txhuas thaiv thiab nws lub taub hau raug rau Nissan.
Piv nrog rau lawv cov neeg ua ntej, cov motors no muaj kev xav ntau dua thiab muaj qhov sib zog dua. Lub sijhawm dhau los, VK45s tau dhau los ua qhov qub thiab ntau lub tshuab niaj hnub tuaj hloov lawv, yog li txij li xyoo 2010 VK45DD thiab VK45DE tsis tau tsim. Koj tuaj yeem ntsib lawv tsuas yog hauv daim ntawv cog lus tub rog, tus nqi yog nyob rau hauv thaj tsam ntawm 100-000 rubles.

Nco tseg! Cov chav nyob hauv nqe lus nug tsuas yog tsim los ntawm cov roj av aspirated. Nws yog tsis yooj yim sua kom tau raws li ib tug sib txawv variation ntawm motors nrog ib tug turbine los yog cov yam ntxwv uas tsis yog cov uas tau sau tseg saum toj no.
Kho thiab kho tawm
VK45DD thiab VK45DE yog cov motors txhim khu kev qha, peb tuaj yeem hais dab tsi txog lawv cov peev txheej zoo. Ib nrab lab kilometers rau cov thawj coj hauv chav kawm ICE nrog lub hwj chim zoo li no tiag tiag. Muaj qhov zoo sib xws txawm nyob rau hauv cov khoom ntawm Nissan txhawj xeeb tsis tshua muaj. VK45-x tsis muaj qhov yuam kev, txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tau xyuas ib qho ntawm cov qauv tsim ua ntej pib ua haujlwm.
Peb tab tom tham txog cov catalysts pem hauv ntej, uas feem ntau raug puas tsuaj vim cov roj tsis zoo thiab cov khoom hnyav. Lawv cov ceramics nkag mus rau hauv lub tog raj kheej thiab ua rau tsis muaj kev puas tsuaj, yuav tsum tau hloov tag nrho lub cev muaj zog. Txhawm rau tiv thaiv qhov no, nws yog qhov txaus los saib xyuas cov catalysts tas li, lossis tsuas yog hloov lawv nrog cov nplaim taws thiab ua cov nti tuning. Nrog rau txoj hauv kev no thiab kev saib xyuas zoo, cov teeb meem ntawm VK45DD thiab VK45DE yuav tsum tsis txhob tshwm sim.
Raws li rau Modernization ntawm cov units, nws yog heev txaus. Lub peev xwm ntawm cov motors hauv nqe lus nug yog 350-370 horsepower nrog 280-340 tshaj tawm. Tuning VK45DD thiab VK45DE nqis los hloov lawv tus qauv. Feem ntau txaus:
- txhim kho camshafts;
- ntxiv dag zog rau CPG;
- upgrade lub tso pa system;
- reflash "lub hlwb".
Xws li manipulations yuav ntxiv 30-50 "nees" mus rau qhov ntws. Tsis tas yuav nruab turbines, turbo kits thiab lwm yam superchargers ntawm VK45s. Qhov no tsis yog tsuas yog tsis tsim nyog ntawm kev siv nyiaj, tab sis kuj tseem cuam tshuam rau cov peev txheej ntawm cov cav. Nws yog qhov muaj txiaj ntsig ntau dua thiab txawj nyeem kom yooj yim hloov cov qauv ntawm cov motors, tau txais kev lees paub thiab tsis muaj teeb meem 30-50 horsepower. Qhov nyiaj tshwj xeeb yog qhov zoo.
