2.0 HDi injini - musimboti wekushanda kweyuniti

Zvakakosha kuziva kuti injini iyi 2.0 HDi inoshanda sei. Muchikwata, mafuta anogoverwa kubva patangi kusvika kune yakakwira yekumanikidza pombi kuburikidza nepasi pekumanikidza pombi. Zvadaro zvinouya kune yakanyanya kudzvanywa mafuta njanji - yakambotaurwa Common Rail system. 

Inopa magetsi anodzorwa nozzles ane yakanyanya kumanikidza ye1500 bar. Kudzvinyirira uku kunobvumira mafuta kuti apinzwe mumasilinda nenzira yekuti kupisa kuri nani kunowanikwa, kunyanya zvichienzaniswa neinjini dzekare. Izvi zvinonyanya kukonzerwa neatomization yemafuta edhiziri kuita madonhwe akanaka kwazvo. Somugumisiro, kushanda kwechikwata kunowedzera.

Iyo yekutanga kugadzirwa kwemagetsi unit kubva kuPSA Group

Boka rePSA - Peugeot Societe Anonyme rakagadzira injini ye2.0 HDi kutsiva mainjini edhiziri ekare. Chimwe chezvinangwa zvikuru chaive chekudzikisa huwandu hwemafuta anoshandiswa, kuzunguzika uye ruzha runoitika kana uchityaira mota. Nekuda kweizvozvo, tsika yebasa yeyuniti yakavandudza zvakanyanya uye kutyaira neinjini iyi kwave kunakidza zvakanyanya. 

Motokari ine injini ye2.0 HDi yainzi Citroen Xantia, idzi dzaive injini dze90 ne110 hp. Iwo mayuniti aifarira mukurumbira wakanaka - aionekwa seakavimbika, ane hupfumi uye emazuva ano.

Iyo yakajairika 2.0 HDi injini kutadza ndiyo turbo. Chii chaunofanira kungwarira?

Imwe yeakajairika 2.0 HDi injini kukundikana ndeye turbocharged kutadza. Iyi ndiyo mhedzisiro yekuunganidza kabhoni muunganidzwa. Tsvina inogona kukonzera matambudziko akawanda anodhura uye kuita kuti upenyu huome kumuridzi wemotokari. Zvino chii chaunofanira kungwarira?

Oiri kuvhara uye kugadzira soot

Kune mayunitsi - ese 2.0 uye 1.6 HDi, yakawanda soot inogona kuungana mukamuri yeinjini. Kushanda kwakakodzera kweinjini kunoenderana zvakanyanya nemitsara yemafuta kuenda uye kubva kune turbocharger. Iko kuburikidza navo iyo mafuta inopfuura, iyo inopa lubrication yemabhengi. Kana paine yakawandisa kabhoni deposits, mitsetse inovharira uye kucheka mafuta ekupa. Nekuda kweizvozvo, mabearings ari mukati me turbine anogona kupisa. 

Zviratidzo zvinogona kutariswa nekusashanda zvakanaka

Nzira yekuudza kana mafuta asiri kugovera zvakanaka ndeyekusunungura kana kusunungura turbo nut. Izvi zvingangove zvichikonzerwa nekuvharwa kwemafuta uye kabhoni kuvaka. Iyo nzungu pachayo mu 2.0 HDi injini inozvivharira uye inongosimbiswa neruoko. Izvi zvinokonzerwa nekuti inodhonzwa kumusoro kana turbocharger iri kushanda nemazvo - nekuda kwemascrews maviri anofamba akapesana uye torsional vibrations.

Zvimwe Zvikonzero Zvinokonzera Kukundikana Kwechikamu

Pane zvimwe zvikonzero nei turbo mune 2.0 HDi injini inogona kutadza. Kazhinji kune zvinhu zvekune dzimwe nyika zvakapinda mukati mechinhu ichi, zvisimbiso zvemafuta zvakapfekwa, kushandiswa kwemafuta eiyo isiriyo yakatarwa, kana kusateedzera nekugadzirisa nguva dzose kwechinhu.

Maitiro ekutarisira 2.0 HDi injini?

Nzira yakanakisa yekuve nechokwadi chekushanda kwakanaka kweinjini ye2.0 HDi kugara uchisevhisi unit, sekutsiva bhandi renguva kana kuchenesa dizeli particulate sefa. Zvingave zvakare pfungwa yakanaka kudzora huwandu hwemafuta mukamuri uye kushandisa iyo chaiyo mhando yemafuta. Izvo zvinodiwawo kuve nechokwadi chehutsanana uye kusavapo kwezvinhu zvekunze mukamuri yeyuniti. Nekuda kwemhinduro dzakadai, injini ichakubhadhara nekushanda kwakatsetseka uye kwakavimbika, kunounza mufaro mukuru wekutyaira.
