Opel Z19DT cav
Txheem
Diesel xyaw tsim los ntawm General Motors yog dav paub tias yog cov khoom siv zoo, txhim khu kev qha thiab ruaj khov zog uas tuaj yeem mus txog ntau pua txhiab mais yam tsis muaj kev kho ntxiv thiab kev saib xyuas kim. Tus qauv Opel Z19DT tsis muaj qhov tshwj xeeb, uas yog ib qho piv txwv turbocharged diesel cav nruab rau ntawm cov tsheb ntawm C thiab H series, tiam thib peb. Los ntawm nws tus qauv tsim, lub cav no yog ib feem qiv los ntawm FIAT, thiab lub rooj sib txoos tau ua ncaj qha rau hauv lub teb chaws Yelemees, ntawm qhov tsis zoo, niaj hnub cog hauv nroog Kaiserslautern.
Thaum lub sijhawm ntawm nws cov khoom tsim los ntawm 2004 txog 2008, plaub lub tog raj kheej diesel cav tau tswj kom yeej lub siab ntawm ntau tus neeg tsav tsheb thiab tom qab ntawd raug yuam tawm ntawm kev ua lag luam los ntawm Opel counterpart nrog Z19DTH cim. Qhov no yog ib qho ntawm kev lag luam tshaj plaws thiab tib lub sijhawm txhim khu kev qha fais fab hauv nws chav kawm. Raws li rau cov analogues tsis tshua muaj zog, Z17DT lub cev muaj zog thiab nws txuas ntxiv Z17DTH tuaj yeem ua rau muaj kev nyab xeeb rau tsev neeg no.

Tsim nta Z19DT
Ib qho yooj yim thiab txhim khu kev qha tsim tso cai rau cov hwj huam no yooj yim kov yeej ntau tshaj 400 txhiab yam tsis muaj kev kho loj.
Cov chav tsev fais fab yog tsim tshwj xeeb rau kev ua haujlwm ntev thiab muaj qhov txawv ntawm qhov zoo ntawm cov hlau thiab kev sib dhos.
Lub npe nrov Common Rail cov cuab yeej siv hluav taws xob kuj tau hloov pauv. Qhov chaw ntawm cov cuab yeej Bosch ib txwm muaj, cov cuab yeej Denso tam sim no tau muab nrog cov cav no. Nws muaj kev ntseeg siab dua, txawm tias nyuaj dua los kho, vim tsis muaj ntau lub chaw pabcuam.
Qhov nrov tshaj plaws faults Z19DT
Nws yuav tsum raug sau tseg tam sim ntawd tias feem ntau ntawm cov teeb meem tshwm sim thaum lub sijhawm ua haujlwm ntawm cov tshuab hluav taws xob sab hauv no tshwm sim vim kev hnav thiab tsim kua muag lossis kev ua haujlwm tsis raug. Lub cev muaj zog no tsis raug kev puas tsuaj, raws li lawv hais tias "Tawm ntawm xiav".
Cov teeb meem feem ntau cov kws tshaj lij hu:
- clogging los yog hlawv ntawm cov lim lim. Kev kho feem ntau yog txiav tawm cov kev pab cuam saum toj no thiab flashing;
- roj injector hnav. Qhov teeb meem yog daws los ntawm kev hloov cov saum toj no thiab tshwm sim los ntawm kev siv cov roj tsis zoo thiab cov roj, nrog rau kev hloov pauv ntawm cov dej ua haujlwm tsis zoo;
- tsis ua hauj lwm ntawm EGR valve. Lub slightest ingress ntawm noo noo ua rau nws souring thiab jamming. Kev kuaj mob thiab kev txiav txim siab los kho lossis hloov cov cuab yeej no yog ua tam sim tom qab kev kuaj mob hauv kev pabcuam tsheb tshwj xeeb;
- Exhaust Manifold teeb meem. Vim overheating, saum toj no tej zaum yuav deformed. Tsis tas li ntawd, feem ntau muaj kev tawg ntawm vortex dampers;
- tawg ntawm lub ignition module. Nws tuaj yeem tshwm sim los ntawm kev siv cov roj cav tsis zoo thiab cov hluav taws xob tsis zoo. Yog li ntawd, thaum hloov, nws yog ib qho tsim nyog yuav tsum tau them sai sai rau cov khoom pom zoo los ntawm cov chaw tsim khoom;
- roj xau ntawm cov pob qij txha thiab los ntawm hauv qab lub gaskets thiab cov ntsaws ruaj ruaj. Qhov teeb meem tshwm sim tom qab lub zog clamping siab dhau lawm, tom qab kho. Qhov teeb meem yog kho los ntawm kev hloov cov saum toj no.
Feem ntau, chav tsev no tau dhau los ua lub hauv paus rau ntau yam kev txhim kho thiab kev txhim kho. Nws tau teeb tsa rau ntau lub tsheb thiab ntau tus neeg tsav tsheb tsis xav yuav daim ntawv cog lus Z19DT rau lawv tus kheej lub tsheb.
Lub tsheb twg yog ntsia rau
Cov motors no tau siv dav hauv 3rd tiam Opel tsheb, suav nrog cov hloov tshiab. Tshwj xeeb, cov motors tau dhau los tshwj xeeb tshaj yog nyob rau ntawm Astra, Vectra thiab Zafira qauv. Lawv muab ib tug txaus theem ntawm lub hwj chim, throttle teb thiab teb, thaum tseem tshuav heev yig thiab ib puag ncig tus phooj ywg.
Raws li kev txhim kho uas ua kom muaj zog ntxiv, feem ntau cov neeg tsav tsheb tau txwv rau kev sib tw nti, uas tuaj yeem ntxiv 20-30 hp. Lwm qhov kev txhim kho yog tsis muaj txiaj ntsig los ntawm qhov kev xav ntawm kev lag luam, thiab nyob rau hauv rooj plaub no nws yog qhov zoo dua los yuav ib qho analogue uas muaj zog dua los ntawm tsev neeg ntawm lub hwj chim. Thaum muas ib daim ntawv cog lus, tsis txhob hnov qab xyuas lub cav naj npawb nrog cov ntawv qhia hauv cov ntaub ntawv.
Nws yog nyob rau ntawm qhov sib tshuam ntawm qhov thaiv thiab qhov chaw kuaj xyuas, yuav tsum du thiab meej, tsis muaj cov ntawv dhia thiab smearing. Txwv tsis pub, cov neeg ua haujlwm kuaj xyuas ntawm lub xeev cov neeg saib xyuas tsheb yuav muaj lus nug tsim nyog, thiab seb tus naj npawb ntawm cov chav tsev no puas tau cuam tshuam thiab, vim li ntawd, lub cev muaj zog yuav raug kuaj ntau yam.
