Txheem
Lub cav no raug suav hais tias yog qhov nrov tshaj plaws diesel chav tsev ntawm lig 90s thiab thaum ntxov 2000s. Nws tau nruab rau ntawm cov tsheb ntawm cov chav kawm sib txawv kiag li, thiab txhua qhov chaw tsav tsheb tuaj yeem tau txais thiab txaus siab rau cov txiaj ntsig tau muab. Cov chav nyob sau npe X20DTL tau tsim los ntawm 1997 txog 2008 thiab tom qab ntawd tau hloov tag nrho los ntawm lub zog hluav taws xob nruab nrog Common Rail system.
Nws yog ib nqi sau cia hais tias twb nyob rau hauv thaum ntxov 2000s, muaj coob tus tau tham txog qhov yuav tsum tau los tsim ib tug tshiab diesel cav, tab sis rau ib tug ntev xya xyoo, lub tuam txhab designers tsis muab ib tug tsim nyog lwm txoj rau lub hwj chim unit.
Tsuas yog lwm qhov tsim nyog rau lub tshuab hluav taws xob no yog lub zog hluav taws xob yuav los ntawm lub tuam txhab los ntawm BMW. Nws yog lub npe nrov M57D25, nrog Common Rail txhaj tshuaj, txawm hais tias ntawm Opel tsheb, nws cov cim zoo li Y25DT, vim qhov peculiarities ntawm ICE kev faib tawm los ntawm GM.

Cov yam ntxwv ntawm cov cuab yeej siv tshuab X20DTL
Nws yog tsim nyog sau cia hais tias thaum lub sij hawm ntawm nws cov tsos, xws li cov yam ntxwv tau txiav txim siab heev mus rau lub engine thiab qhib lub zeem muag zoo heev rau Opel tsheb nruab nrog cov units. 16-valve lub tog raj kheej lub taub hau thiab hluav taws xob TNDV tau suav tias yog ib qho ntawm cov kev daws teeb meem loj tshaj plaws ntawm lawv lub sijhawm.
Lub cev muaj zog no yog ib tus neeg sawv cev tseem ceeb ntawm cov khoom siv hluav taws xob zoo hauv cov tshuab hluav taws xob uas tsim tawm thaum kawg ntawm lub xyoo pua xeem. Nws tau nruab nrog aluminium valve cover thiab ib tug cam khwb cia hlau thaiv. Nyob rau hauv lub neej yav tom ntej, tib qhov kev hloov kho tau ua tiav, thiab lub hau npog tau los ua yas, thiab lub thaiv yog ua los ntawm cov hlau alloy.
Ib tug txawv feature ntawm lub cev muaj zog yog lub xub ntiag ntawm ib tug loj tus naj npawb ntawm kho qhov ntau thiab tsawg ntawm lub tog raj kheej-piston pab pawg neeg thiab cov kev sib txuas pas nrig mechanism.
Lub sijhawm tsav yog tus cwj pwm los ntawm kev muaj ob txoj hlua - ib ob kab thiab ib kab ib leeg. Nyob rau tib lub sijhawm, thawj tus tsav lub camshaft, thiab qhov thib ob yog tsim los rau VP44 txhaj tshuaj twj tso kua mis, uas tau muaj kev tsis txaus siab ntau heev txij li thaum nws tso tawm vim tsim tsis zoo.
Tus qauv X20DTL tau dhau los ua lub hauv paus rau kev txhim kho ntxiv thiab kev hloov kho, uas tso cai rau kev txhim kho lub tuam txhab lub cav lub cav. Thawj lub tsheb tau txais xws li chav tsev, Opel Vectra B, thaum kawg kis mus rau yuav luag txhua qhov kev hloov kho ntawm cov tsheb nruab nrab.
Feem ntau tawg ntawm X20DTL fais fab units
Nyob rau lub sijhawm ntev ntawm kev ua haujlwm ntawm lub zog hluav taws xob no, cov neeg tsav tsheb tau txheeb xyuas tag nrho cov teeb meem ntawm thaj chaw thiab qhov chaw, qhov zoo ntawm qhov kuv xav kom txhim kho. Txawm hais tias nws yuav tsum tau muab sau tseg tias feem ntau ntawm lub zog hluav taws xob tau yooj yim tsav 300 txhiab km yam tsis muaj kev kho, thiab cov peev txheej ntawm lub cev muaj zog yog 400 txhiab thiab qhov kev puas tsuaj loj tshwm sim tom qab cov peev txheej no tas lawm.
Ntawm cov teeb meem feem ntau uas lub cav no nto moo rau, cov kws tshaj lij sau tseg:
- kev txhaj tshuaj lub kaum sab xis tsis raug. Qhov teeb meem yog los ntawm stretching lub sij hawm saw. Lub teb ntawm lub tsheb no pib tsis meej pib. Muaj peev xwm jerks thiab floating revolutions thaum txav;
- depressurization ntawm roj hmab-hlau gaskets thiab roj injectors, traverses. Tom qab ntawd, muaj kev pheej hmoo ntawm cov roj cav nkag mus rau hauv cov roj diesel thiab airing cov roj system;
- kev puas tsuaj rau cov kev taw qhia los yog nro rollers ntawm lub sij hawm chains. Cov kev tshwm sim tuaj yeem sib txawv heev. Los ntawm cov nroj tsuag tsis ruaj khov rau cov lim lim.
- ua tsis tiav ntawm TNDV VP44. Lub tshuab hluav taws xob ntawm lub twj tso kua mis no yog qhov tsis muaj zog ntawm yuav luag txhua lub tsheb Opel uas tsim tawm lub sijhawm no. Kev ua txhaum me me los yog qhov tsis xws luag hauv qhov no ua rau lub tsheb tsis pib txhua, lossis ua haujlwm ntawm ib feem peb ntawm nws lub zog ua tau. Kev ua haujlwm tsis zoo raug kuaj pom nyob rau hauv cov xwm txheej ntawm kev pabcuam tsheb ntawm qhov muag;
- hnav thiab txhaws cov kav dej. Qhov teeb meem no tshwm sim thaum siv cov roj tsis zoo thiab cov roj nplua nyeem. Lub tsheb poob lub zog, tsis ruaj khov hauv kev ua haujlwm yog manifested. Tsuas yog kev tu tag nrho ntawm qhov system tuaj yeem txuag qhov xwm txheej.
Tag nrho cov teeb meem saum toj no tsis tshua pom muaj nyob hauv cov tsheb, tom qab kev kho dua tshiab thiab lub zog hluav taws xob nrog cov mais tsawg. Nws yog ib nqi sau cia hais tias lub motors ntawm no series muaj ib tug loj tus naj npawb ntawm kho qhov ntau thiab tsawg thiab nws muaj peev xwm rov qab tau txhua lub hwj chim unit yuav luag indefinitely.
Muaj peev xwm hloov nrog lub zog nce ntxiv
Ntawm cov muaj zog tshaj sab hauv combustion xyaw uas tuaj yeem hloov pauv rau cov qauv no, nws tsim nyog hais txog Y22DTR nrog 117 lossis 125 hp. Lawv tau ua pov thawj lawv tus kheej hauv kev xyaum thiab yuav ua kom lub zog ntawm lub tshuab ua kom muaj zog, yam tsis muaj kev noj ntau ntxiv. Nyob rau tib lub sijhawm, rau cov neeg uas xav txhim kho lub zog tshiab thiab zoo ib puag ncig hauv lawv lub tsheb, xyuam xim rau Y20DTH, uas ua raws li EURO 3 ib puag ncig cov qauv, nws lub zog yog 101 hp. thiab tseem yuav tso cai rau koj los yeej ob peb los ntawm kev ntxiv ob peb tus nees rau lub zog.
Ua ntej hloov lub cev muaj zog nrog daim ntawv cog lus, lossis txhawm rau txhim kho lub zog muaj zog dua, koj yuav tsum ua tib zoo xyuas tag nrho cov lej ntawm cov khoom seem uas tau teev tseg hauv cov ntaub ntawv.
Txwv tsis pub, koj khiav txoj kev pheej hmoo ntawm kev tau txais cov khoom tsis raug cai lossis raug nyiag thiab tsis ntev los no koj tuaj yeem mus rau hauv thaj chaw nplua. Rau Opel X20DTL cav, tus qauv qhov chaw qhia tus lej yog qhov qis ntawm qhov thaiv, me ntsis rau sab laug thiab ze rau qhov chaw kuaj xyuas. Qee qhov xwm txheej, nrog rau lub hau npog aluminium thiab lub cam khwb cia hlau, cov ntaub ntawv no tuaj yeem nyob rau ntawm lub valve npog lossis ntawm qhov chaw uas nws txuas rau lub ntsiab ntawm chav tsev.
