Audi A4 A6 B8 2 0 Tdi Quattro Crankshaft

VW 3.6 FSI engine yog VR6 (nqaim V-series EA390) petrol 3.6 liter engine. Nws yog thawj zaug qhia hauv 2005 hauv Audi Q7 (BHK thiab BHL xyaw) thiab tom qab ntawd hauv lwm cov Volkswagens: Passat R36 thiab CC (BLV, BWS), Phaeton (CHNA thiab CMVA), Touareg (CGRA, thiab lwm yam). 3. Kev hloov pauv loj dua ua rau muaj zog thiab lub zog loj dua piv rau lub cav 3.2L.

Lub cav 3.6 FSI muaj qhov tshiab 10.6 degree VR zoo li lub tog raj kheej thaiv ua los ntawm cov hlau cam khwb cia thiab txheej graphite. Lub tog raj kheej offset kuj tau hloov ntawm 12.5mm mus rau 22mm. Lub thaiv tshiab muaj qhov ntev tib yam li 3.2 VR6 manifold txhaj tshuab. Cov roj twj tso kua mis yog kev koom ua ke hauv lub cav thaiv. Tam sim no, lub cav muaj cam khwb cia hlau crankshaft, tab sis nws tseem nqa los ntawm xya lub ntsiab bearings. Tseem muaj cov tshiab aluminium alloy pistons nrog graphite txheej.

Lub cav 3.6 VR6 muaj 24- lub tog raj kheej lub taub hau ua los ntawm cov khoom siv hluav taws xob hypereutectic "Alusil" aluminium-silicon alloy (AlSi17Cu4Mg). Lub tog raj kheej lub taub hau tsim yog tib yam li 3.2 FSI V6 cav lub taub hau. Lub cav muaj dual nyiaj siv ua haujlwm saw tsav camshafts. Ib lub camshaft rau tag nrho cov intake li qub thiab ib qho rau tag nrho cov pa valve. Lawv txhua tus tau nruab nrog lub sijhawm hloov kho tas li. Qhov siab tshaj plaws camshaft hloov kho rau lub sijhawm sib txawv ntawm lub valve yog raws li hauv qab no: 52 degrees rau lub sijhawm noj; 42 degrees rau kev tso pa tawm. Lub tog raj kheej taub hau muaj 4 li qub rau ib lub tog raj kheej (24 li qub hauv tag nrho). Lawv txawv ntawm qhov ntev. Cov khoom siv valve yog 33.2 hli inch; cov pa tawm li qub yog 30.2 mm nyob rau hauv txoj kab uas hla; ob lub valve muaj ib txoj kab uas hla 6 mm.

Lub cav muaj kev txhaj tshuaj ncaj qha FSI (Fuel Stratified Injection). Cov injectors yog ntsia los ntawm qhov nkag sab. Lub qhov rau lub tog raj kheej 1, 3 thiab 5 yog nyob rau saum toj ntawm cov khoom noj khoom haus; cov injectors rau lub tog raj kheej 2, 4 thiab 6 yog mounted hauv qab ntawm qhov intake manifold. Lub twj tso kua mis siab siab nyob rau ntawm lub tog raj kheej lub taub hau thiab yog tsav los ntawm lub camshaft sij hawm saw. Nws tsim roj ntawm lub siab ntawm 1,595 psi (110 bar). Lub 3.6 FSI muaj qhov sib txawv ntawm qhov ntev ntawm cov khoom siv yas uas hloov lub zog thiab lub zog los ntawm kev qhib thiab kaw lub suab nrov nrov tswj li qub. Kev teeb tsa hluav taws xob yog nyob ntawm 0-1,200 thiab 4,{15}} ntxiv rau rpm; txoj hauj lwm torque yog nyob ntawm 1,200 mus rau 4, 000 rpm. Lub cav no tseem muaj lub tshuab hluav taws xob tswj / lub cev (tsav-los-xaim).

Lub cav yog tswj los ntawm ECU Bosch Motronic MED 9.1. Lub ignition kuj yog hluav taws xob. Lub tso pa tawm yog nruab nrog ob lub pre-catalytic converters thiab ob lub ntsiab catalytic converters. Nrog rau tag nrho cov yam ntxwv no, lub cav 3.6 FSI ua raws li Kev Siv Hluav Taws Xob Tsawg (LEV2) thiab European Euro 5 emission qauv.

Muaj ob lub ntsiab ntawm cov khoom siv crankshaft, ib qho yog steel crankshaft thiab lwm yam yog hlau crankshaft. Cov hlau crankshaft feem ntau yog cov khoom siv hlau uas txiav txim siab lub ntsiab zoo ntawm audi a4 b8 2.0 tdi crankshaft, thiab lwm yam yog kev siv tshuab thiab kev ua haujlwm raug. Cov hlau crankshaft feem ntau siv cov txheej txheem fillet dov. Audi A6 crankshaft thiab Audi A4 Crankshaft kev lag luam precision yog pom ntawm qhov muag liab qab. Ntxiv nrog rau cov txheej txheem fillet dov, lub nodular cam khwb cia hlau crankshaft kuj yuav tsum tau nitrided, thiab cov nitrided crankshaft yog xim dub. Nws raug pom zoo rau cov neeg zoo tib yam mus yuav Audi A4 Quattro Crankshaft mus yuav cov thawj lub cav tsim, uas tuaj yeem lav qhov zoo. Thaum xaiv, tsuas yog ua tib zoo saib kom tsis txhob muaj kab mob trachoma, rub cov cim, thiab lwm yam hauv qhov nkhaus, thiab feem ntau yuav tsis muaj teeb meem. Forged steel cov ntaub ntawv feem ntau yog nruab nrab carbon steel thiab nruab nrab carbon tsawg alloy steel, xws li 45 steel, 53 steel, 35CrMo, 40Cr, thiab lwm yam. Cov qib ntawm ductile hlau crankshafts yog QT600-3, QT700-2, QT800-2, QT900-2, QT900-5.
