Iwo anapereka ntchito yabwino kwambiri, ndipo unit palokha ankaona ngati yamakono. Zinali kuyankha kwa injini zamtundu wa Mercedes ndi BMW.

Mayankho apangidwe omwe amagwiritsidwa ntchito mu unit

Kwa chipangizochi, chipika chachitsulo chokhala ndi masilinda asanu ndi limodzi opangidwa mu 90 ° V chinasankhidwa, ndipo mutu wa silinda wa aluminiyamu wa 24-valve unayikidwa pamwamba. Injini ya 2.5 TDi idagwiritsanso ntchito shaft ya balancer yomwe idapangidwa kuti ichepetse kugwedezeka ndi kugwedezeka zomwe zimapangitsa chikhalidwe chapamwamba chantchito.

Zolakwika mu mtundu wa 2.5 TDi - zimawapangitsa chiyani?

Mavuto osasangalatsa kwambiri okhudzana ndi magwiridwe antchito a unit amaphatikiza kulephera kwa jakisoni. Choyambitsa nthawi zambiri chinali kulephera kwa mpope wamafuta, magetsi owongolera, kapena maginito omwe amawongolera metering yamafuta.

Izi zinali chifukwa cha mtundu wa zigawo zomwe zimagwiritsidwa ntchito. Pampu yogawa ma radial imakhudzidwa kwambiri ndi zonyansa mumafuta kuposa mtundu wa axial. Pachifukwa ichi, kuwonongeka kwa makina ku chinthucho kunachitika nthawi zambiri.

Kodi chomwe chingayambitse mavutowa ndi chiyani?

Zimanenedwanso kuti kulephera kwa injini ya 2.5 TDi ndi chifukwa cha kuyang'anira pakupanga. Zolephera zambiri ziyenera kudziwika mosavuta panthawi yoyesera, kotero zikuyembekezeka kuti injiniya wa Volkswagen sanapereke chidwi chokwanira ku mayeserowo ndipo chipangizocho sichinayesedwe pamtunda woyenera.

Mafunso ofunikira pakugwiritsa ntchito makina

Ndikoyenera kudziwa kuti ndi kusamalira bwino kunali kotheka kupewa kuwonongeka, kuphatikizapo okwera mtengo. Tikunena pano za dongosolo la nthawi, lomwe linali ndi chizolowezi chosokonekera chifukwa cha kuperewera kwa zida zomwe zimagwiritsidwa ntchito. Yankho labwino linali losintha lamba wanthawi yamakilomita 85 aliwonse. km, yomwe ili kale kwambiri kuposa momwe wopanga adapangira. Ngati dongosolo lokhalo linasweka, izi zikutanthauza kuti pafupifupi chiwonongeko chonse cha unit.

Ngati mukufuna kugula chitsanzo galimoto okonzeka ndi injini 2.5 TDi, ndi bwino kusankha galimoto pambuyo 2001. Zitsanzo za njinga yamoto isanafike tsiku ili yodziwika ndi mlingo wolephera - pambuyo 2001 mavuto ambiri anathetsedwa.

Ndi zosintha ziti zomwe zapangidwa kugawoli?

Volkswagen yasinthanso gawoli kuti lichotse zovuta zokhumudwitsa. Ntchitoyi inaphatikizapo kusinthidwa kwa majekeseni, komanso kukonzanso bwino kamangidwe ka unit, kusintha kwa nthawi.

Zovuta kwambiri za injini ya 2.5 TDi

Zowonongeka zomwe zimawoneka nthawi zambiri zinali zovuta ndi pampu yamafuta, yoyendetsedwa ndi crankshaft. Pamene injini ikugwira ntchito, pampu imatha kulephera, kusiya galimotoyo popanda mafuta. Zotsatira zake, mwayi wotsekera pampu yamafuta chifukwa cha kuvala kwa camshaft ukuwonjezeka.

Injini za 2.5 TDi zilinso ndi zovuta ndi turbine. Izi zikugwiranso ntchito kumitundu yamayunitsi omwe ayenda mtunda wopitilira 200 km. km. Nthawi zina kutaya kwakukulu kwa mphamvu kumayambitsidwanso ndi kuwonongeka kwa valve ya EGR ndi mita yothamanga.

Zomwe muyenera kuyang'ana posankha galimoto yokhala ndi unit iyi?

Ngati mukufuna kupeza njira yagawo yomwe ingakhale mwangozi kwambiri, muyenera kuyang'ana injini ya 2.5 TDi V6 yokhala ndi 155 hp. kapena 180 hp Euro 3 ikugwirizana. Kugwiritsa ntchito ma motors awa kumalumikizidwa ndi zovuta zochepa.
