nws yog dab tsi? Ntaus thiab yam ntxwv. Video.

Yog tias peb saib cov yam ntxwv ntawm Volkswagen, Audi, Skoda tsheb, peb yuav pom cov cav nyob rau hauv kab ntawm lub hwj chim units, uas yog abbreviated li FSI, TSI, TFSI. Peb twb tau tham txog FSI ntawm peb Vodi.su autoportal, nyob rau hauv tsab xov xwm no kuv xav nyob rau hauv TFSI hwj chim units nyob rau hauv ntau yam.

TFSI stands for abbreviation

Raws li koj tuaj yeem twv, tsab ntawv T qhia txog qhov muaj lub tshuab hluav taws xob. Yog li, qhov sib txawv tseem ceeb ntawm FSI yog lub turbocharger, ua tsaug rau cov pa roj carbon monoxide re-burned, yog li TFSI yog qhov txawv ntawm lawv cov kev ua tau zoo thiab ib puag ncig tus phooj ywg - qhov tsawg kawg nkaus ntawm CO2 nkag rau hauv huab cua.

Lub npe TFSI sawv cev rau Turbo roj stratified txhaj tshuaj, uas txhais tau tias: turbocharged cav nrog stratified roj txhaj. Ntawd yog, nws yog kev hloov pauv, rau nws lub sijhawm, lub kaw lus ntawm kev txhaj tshuaj ncaj qha rau hauv lub combustion chamber ntawm txhua tus neeg piston, nruab nrog lub turbine.

Ua tsaug rau qhov kev qhia no, cov txiaj ntsig zoo tau tiav:

siab cav fais fab;
loj torque;
kuj tsis tshua muaj roj noj, txawm hais tias turbocharged cav yog ib txwm tsis yig.

Feem ntau hom no lub cev muaj zog yog ntsia rau ntawm Audi tsheb. Volkswagen, ntawm qhov tod tes, nyiam siv cov txheej txheem zoo sib xws ntawm nws cov tsheb - TSI (turbo engine nrog kev txhaj tshuaj ncaj qha). FSI, nyob rau hauv lem, tsis tau nruab nrog lub turbine.

Thawj thawj zaug TFSI tau teeb tsa ntawm Audi A4 qauv. Lub hwj chim chav tsev muaj ib tug ntim ntawm 2 litres, thaum muab tawm 200 horsepower, thiab tractive zog yog 280 Nm. Txhawm rau ua tiav cov txiaj ntsig zoo ib yam ntawm lub cav ntawm cov qauv tsim ua ntej, nws yuav tsum muaj qhov ntim ntawm qhov kev txiav txim ntawm 3-3,5 litres thiab nruab nrog 6 pistons.

Nyob rau hauv 2011, Audi engineers ho upgraded TFSI. Niaj hnub no, lub tshuab hluav taws xob ob-liter thib ob no qhia txog cov yam ntxwv hauv qab no:

211hp ua ntawm 4300-6000 rpm;
torque 350 Nm ntawm 1500-3200 rpm.

Ntawd yog, txawm tias tsis yog tus kws tshaj lij tuaj yeem pom tias cov cav ntawm hom no txawv ntawm lub zog zoo ntawm ob qho tib si qis thiab siab ceev. Txaus nws los sib piv: hauv 2011, Audi tau txiav tawm 3.2-liter FSI nrog 6 pistons, uas ua rau 255 hp. ntawm 6500 rpm, thiab lub zog ntawm 330 Newton meters tau tiav ntawm 3-5 txhiab rpm.

Ntawm no, piv txwv li, yog cov yam ntxwv ntawm Audi A4 TFSI 1.8 liter, tsim nyob rau hauv 2007:

zog 160hp ntawm 4500 rpm;
Qhov siab tshaj plaws torque ntawm 250 Nm yog mus txog ntawm 1500 rpm;
acceleration mus rau pua pua yuav siv sij hawm 8,4 vib nas this;
noj nyob rau hauv lub nroog voj voog (kev ceev kis tau tus mob) - 9.9 litres ntawm A-95;
noj nyob rau hauv txoj kev loj - 5.5 litres.

nws yog dab tsi? Ntaus thiab yam ntxwv. Video.

Yog hais tias peb coj tag nrho cov log tsav version ntawm Audi A4 Allroad 2.0 TFSI Quattro, ces ob-liter turbocharged TFSI muaj peev xwm tsim 252 hp. Acceleration mus rau pua pua yuav siv sij hawm nws 6.1 vib nas this, thiab noj yog 8,6 litres nyob rau hauv lub nroog nrog ib tug tsis siv neeg kis tau tus mob thiab 6,1 litres sab nraum lub nroog. Lub tsheb muaj roj av A-95.

Tam sim no xav tias qhov txawv. Volkswagen Passat 2.0 TSI:

zog 150hp ntawm 6000 rpm;
torque - 200 Nm ntawm 3000 rpm;
acceleration mus rau pua pua - 9,4 vib nas this;
Nyob rau hauv lub nroog voj voog, ib lub tsheb nrog mechanics noj 11,4 litres ntawm A-95;
Lub voj voog ntxiv hauv nroog - 6,4 litres.

Ntawd yog, piv rau FSI, lub cav TFSI tau dhau los ua ib kauj ruam tom ntej ua tsaug rau kev teeb tsa ntawm lub turbocharger. Txawm li cas los xij, cov kev hloov pauv kuj cuam tshuam rau qhov tsim nyog.

Tsim nta ntawm TFSI xyaw

Lub turbocharger yog ntsia rau hauv cov pa tawm manifold, uas tsim ib qho kev sib koom ua ke, thiab cov pa roj tom qab tau rov muab rau cov khoom noj khoom haus. Cov roj siv hluav taws xob tau raug hloov pauv vim yog siv lub twj tso kua mis lub twj tso kua mis hauv lub tshuab hluav taws xob thib ob, uas muaj peev xwm nqus tau ntau dua.

Cov roj priming twj tso kua mis yog tswj los ntawm lub tshuab hluav taws xob tswj, yog li tus nqi ntawm cov roj-cua sib tov uas tau txhaj rau hauv lub pistons nyob ntawm qhov load tam sim no ntawm lub cav. Yog tias tsim nyog, lub siab yog nce ntxiv, piv txwv li, yog tias lub tsheb txav hauv qis qis qis qis. Yog li, nws muaj peev xwm ua kom tau txais txiaj ntsig tseem ceeb hauv kev siv roj.

nws yog dab tsi? Ntaus thiab yam ntxwv. Video.

Lwm qhov sib txawv tseem ceeb ntawm FSI yog nyob rau hauv qab ntawm pistons. Lub combustion chambers nyob rau hauv lawv yog me me, tab sis nyob rau tib lub sij hawm lawv nyob ib tug loj cheeb tsam. Daim ntawv no tso cai rau koj los ua haujlwm zoo nrog kev txo qis ntawm compression.

Feem ntau, TFSI fais fab units ua haujlwm zoo ib yam li tag nrho lwm cov cav ntawm Volkswagen kev txhawj xeeb:

ob lub voj voog ntawm cov roj system - qis thiab siab;
Lub tshuab hluav taws xob tsis tshua muaj xws li: lub tank, lub twj tso kua mis roj, cov roj lim dej ntxhib thiab zoo, roj sensor;
qhov kev txhaj tshuaj ncaj qha, piv txwv li lub injector, yog ib feem tseem ceeb ntawm kev kub siab Circuit Court.

Cov kev khiav hauj lwm hom ntawm tag nrho cov Cheebtsam yog tswj los ntawm cov tswj unit. Nws ua hauj lwm raws li complex algorithms uas txheeb xyuas ntau yam tsis tau ntawm lub tsheb lub tshuab, raws li cov lus txib raug xa mus rau lub actuators thiab ib tug nruj ntsuas tus nqi ntawm cov roj nkag mus rau hauv lub system.

Txawm li cas los xij, turbine cav xav tau txoj hauv kev tshwj xeeb, lawv muaj ntau qhov tsis zoo piv rau cov pa cua:
