Volkswagen-Audi tsheb muaj ntau heev nyob rau hauv Russia. Ib qho ntawm cov yam ntxwv ntawm cov tshuab no yog cov cav turbocharged. Thiab yog tias ua ntej lub turbine tsuas tuaj yeem pom ntawm lub cav diesel, ces VAG siv nws txhua qhov chaw ntawm cov roj av cav.

Lub hom phiaj ntawm kev hloov kho tshiab yog txhawm rau ua kom muaj txiaj ntsig zoo ntawm chav tsev thaum tuav nws cov ntim ua haujlwm. Txij li cov roj efficiency tseem ceeb niaj hnub no, nws yog tsis yooj yim sua kom nce lub ntim ntawm lub combustion chamber indefinitely. Yog li ntawd, automakers mus rau txawv tricks. Ib qho piv txwv ntawm kev ua haujlwm zoo li no yog lub cav TSI. Nws yog dab tsi thiab dab tsi yog cov yam ntxwv ntawm lub tshuab fais fab no? Xav txog hauv peb tsab xov xwm niaj hnub no.

yam ntxwv

The TSI engine is a gasoline powertrain used in Volkswagen, Skoda and Audi. Ib tug yam ntxwv txawv ntawm lub TSI engine yog lub xub ntiag ntawm ib tug ob chav turbocharger thiab ib tug ncaj qha roj txhaj system (tsis txhob yuav tsis meej pem nrog lub Common Rail). Tau tsim ib qho tshwj xeeb tsim, German engineers ua tiav cov roj efficiency ntawm chav tsev nrog cov yam ntxwv zoo.

Raws li koj tuaj yeem pom, ntau lub zog ntawm cov chav nyob yog qhov dav heev.

Device

Nws tsim nyog sau cia tias TSI engines tau raug kho dua tshiab. Yog li ntawd, ib qho txhuas lub tog raj kheej thaiv, kev hloov kho kom haum thiab tso pa tawm, nrog rau kev txhim kho cov roj txhaj tshuaj tau nruab ntawm no. Txawm li cas los xij, thawj yam ua ntej.

Superchargers

Turbine yog lub hauv paus tseem ceeb vim tias cov yam ntxwv zoo li no tau ua tiav. Superchargers ntawm TSI motors nyob rau ntawm qhov sib txawv ntawm qhov thaiv. Lub mechanism yog powered los ntawm lub zog ntawm cov pa pa. Lub tom kawg tau teeb tsa hauv kev txav lub impeller, uas, los ntawm cov tsav tshwj xeeb, tso cua nkag mus rau hauv cov khoom siv manifold. Nco ntsoov tias cov pa turbocharged xyaw muaj ntau qhov tsis zoo. Tshwj xeeb, qhov no yog qhov cuam tshuam ntawm turbo lag - qhov poob ntawm lub zog ntawm lub cav sab hauv combustion ntawm nws qee qhov nrawm. TSI motors yog dawb los ntawm qhov tsis zoo no ua tsaug rau ntau lub superchargers. Ib qho ua haujlwm ntawm qhov qis qis, thiab qhov thib ob yog txuas nrog siab. Qhov no yog yuav ua li cas lub siab tshaj plaws torque yog pom nyob rau hauv ib tug ncaj ntau yam.

Kev txhawb nqa ua haujlwm li cas?

Nyob ntawm seb muaj pes tsawg lub kiv puag ncig ntawm lub crankshaft, muaj cov qauv hauv qab no ntawm kev ua haujlwm ntawm qhov system:

  • Tsis txhob haus. Hauv qhov no, lub turbine tsis koom nrog kev ua haujlwm. Kev hloov pauvcav tsis pub tshaj ib txhiab ib feeb. Throttle tswj valve kaw.
  • Kev ua haujlwm ntawm lub tshuab supercharger. Lub tshuab no yog qhib thaum lub kiv puag ncig yog los ntawm ib mus rau ob thiab ib nrab txhiab ib feeb. Cov neeg kho tshuab supercharger pab muab lub zog zoo thaum pib lub tsheb los ntawm qhov chaw nres.
  • Kev sib xyaw ntawm turbine thiab supercharger. Qhov no tshwm sim ntawm revs ntawm 2,500 thiab 3,500.
  • Turbocharger ua haujlwm. Lub tshuab blower tsis pib lawm. Supercharging tsuas yog muab los ntawm turbine impeller nyob rau hauv hom ceev ntawm peb thiab ib nrab txhiab thiab siab dua.

Raws li RPM nce, huab cua siab npaum li cas. Yog li, nyob rau hauv hom thib ob, qhov ntsuas no yog kwv yees li 0.17 MPa. Hauv qhov thib peb, lub zog siab nce mus txog 0.26 MPa. Nyob rau hauv high speeds, lub siab txo qis me ntsis. Qhov no yog ua los ntawm kev tiv thaiv cov nyhuv ntawm detonation (spontaneous ignition ntawm cov roj av sib tov, uas yog nrog los ntawm ib tug yam ntxwv tshuab rau lub piston crown). Thaum lub turbocharger ua haujlwm, qhov siab yog 0.18 MPa. Tab sis qhov no tsuas yog txaus los muab lub zog siab thiab lub zog thaum tsiv ntawm qhov nrawm.

txias system

Vim lub cav nyob rau hauv qhov kev thauj khoom tas li, nws xav tau txias txias.

Yog li, lub kaw lus muaj cov kav dej uas dhau los ntawm kev sib tshuam. Ua tsaug rau qhov no hauv cylinderscua txias nkag. Qhov no ua kom muaj kev sib xyaw ua kom tiav ntau dua thiab ua rau muaj kev nce hauv lub zog ntawm lub cav.

Txhaj tshuaj

TSI engine has a modernized injection system. Nws belongs rau hom tam sim ntawd. Yog li ntawd, roj nkag mus rau hauv lub chamber tam sim ntawd, bypassing lub classic roj tsheb ciav hlau. Raws li tau sau tseg los ntawm kev tshuaj xyuas, kev ua haujlwm ntawm kev txhaj tshuaj ncaj qha yog xav tau thaum nrawm nrawm. Lub tsheb cia undermines los ntawm hauv qab. Tab sis kev siv xws li kev txhaj tshuaj yog tsom tsis tsuas yog txhawm rau txhim kho kev ua haujlwm thiab lub zog ntawm lub cav, nws pab txo qis kev siv roj cav.

Lub tog raj kheej thaiv

TSI engine nta lub teeb yuag txhuas lub tog raj kheej thaiv. Kev siv xws li ib tug alloy ho txo qhov loj ntawm lub cev muaj zog. Qhov nruab nrab, xws li ib lub thaiv hnyav 14 kg tsawg dua cam khwb cia hlau. Tsis tas li, tus qauv tsim siv lwm cov camshafts zais tom qab lub hau yas. Yog li, kev ua haujlwm siab ntawm lub tshuab hluav taws xob sab hauv yog ua tiav.

Problems

TSI engines muaj teeb meem dab tsi? Ib qho ntawm cov kab mob ntawm cov nroj tsuag hluav taws xob no yog kev siv roj ntau ntxiv. Ntxiv mus, lub maslozhor tsis yog tsis tshua muaj txawm nyob rau hauv lub cav tshiab. Reviews hais txog 1.4 TSI engines? Cov units no haus txog li 500 grams roj ib 1000 kilometers. Qhov ntawd yog ntau heev. Cov tswv feem ntau yuav tsum tswj cov qib nrog lub dipstick. Yog hais tias koj miscalculate lub sij hawm, koj muaj peev xwm ntes roj tshaib plab, uas yog fraught nrog ib tug txo nyob rau hauv cov kev pab cuam ntawm lub TSI engine, uas yog nws piston pawg. Cov teeb meem no puas tuaj yeem daws tau? Hmoov tsis zoo, qhov no"ib tus kab mob kho tsis tau" ntawm tag nrho cov TSI motors, yog li tus tswv tsuas tuaj yeem saib xyuas lub dipstick tsis tu ncua thiab nqa ib lub raj mis roj nrog nws mus rau saum.

Lwm qhov teeb meem uas xaus rau qhov kev cia siab ntawm lub cav 1.4 TSI yog qhov tsis ua haujlwm ntawm lub turbine. Nws yog feem ntau "pov" nrog roj, thiab los ntawm 80 txhiab bearing plays tshwm. Lub turbine tsis tuaj yeem tso pa tawm raws li qhov xav tau, uas ua rau cov khoom siv tsis zoo thiab hloov tus cwj pwm ntawm lub tsheb. Tus nqi ntawm kev kho lub supercharger yog kwv yees li 60 txhiab rubles, thiab muaj ob peb lub turbines hauv lub cav.

Qhov kev poob siab tom ntej uas hu rau cov lus nug txog kev ntseeg siab ntawm TSI cov cav yog lub tshuab xa tawm roj. Lawv ua hauj lwm los ntawm ib tug saw uas feem ntau stretches. Yog vim li cas rau qhov no yog heev loads. Nyob rau hauv xyoo tas los no, German chaw tsim tshuaj paus tau pib nruab ib txoj siv tawv tsav. Raws li cov chaw tsim khoom, nws lub zog tau nce ob npaug. Qhov no tau txhim kho qhov xwm txheej me ntsis, txawm li cas los xij, tseem muaj ntau lub tsheb nyob rau hauv kev ua lag luam nrog lub sijhawm qub.

TSI engine kav ntev npaum li cas? Raws li cov chaw tsim khoom, nws cov peev txheej yog li peb puas txhiab kilometers. Txawm li cas los xij, hauv kev xyaum, cov motors no khiav 150-200 kilometers. Dab tsi tseem ceeb ua rau qhov teeb meem yog qhov thaiv aluminium. Nws yog xyaum dhau kev kho. Tsis muaj lub tsho ntub dej li niaj zaus uas tuaj yeem hloov tau, yog li thaum tsis ua haujlwm, TSI lub cev muaj zog yooj yim dua los hloov nrog ib qho tshiab, uas, los ntawm txoj kev, yog kim heev.

Zoo kawg

So, we find out what the TSI engine is. Lub tswv yim tom qab lub cev muaj zog yog qhov zoo. Cov Germans nrhiav los ua lub cav muaj zog thiab tsim tau, kom tau txais kev ua haujlwm siab tshaj plaws los ntawm nws. Txawm li cas los xij, nyob rau hauv kev nrhiav kev ua tau zoo tshaj plaws, cov engineers tsis tau coj mus rau hauv tus account ntau ntawm nuances uas twb tau raug kho nyob rau hauv cov txheej txheem ntawm loj zus tau tej cov cav. Nws puas tsim nyog yuav lub tsheb nrog lub cav zoo li no? Cov kws tshaj lij muab cov lus teb tsis zoo, txij li cov peev txheej ntawm cov motors no tsawg heev. Tsis tas li ntawd feem ntau muaj teeb meem nrog cov saw tsav. Txawm hais tias muaj kev ua haujlwm siab thiab siv roj tsawg, koj yuav tsum tsis txhob yuav lub tsheb zoo li no. Tus tswv yuav ntsib kev kho tsis tau zoo thiab kev nqis peev hnyav heev.
