Cav cim nyob rau hauv lub tsheb ntawm lwm hom thiab nyob rau hauv uas lub tsheb nws twb ntsia

Lub cav 1.9 JTD tuaj yeem sau npe txawv. Nws nyob ntawm qhov kev txiav txim siab ua lag luam ntawm cov tuam ntxhab siv nws. Opel siv lub npe CDTi, Saab siv lub npe TiD thiab TTiD. Lub cav tau nruab rau ntawm cov tsheb xws li:

Twin turbos pib siv nyob rau hauv 180 hp versions. thiab 190 hp nrog lub siab tshaj plaws torque ntawm 400 Nm ntawm 2000 rpm. Thawj ntawm cov units tau nruab rau ntawm lub tsheb ntawm ntau hom, thiab qhov thib ob tsuas yog ntawm cov tsheb ntawm Fiat kev txhawj xeeb.

Kev ua haujlwm ntawm lub tshuab tsav - dab tsi los nrhiav?

Cov tsheb nruab nrog lub zog no ua tau zoo. Kev ua haujlwm tau zoo heev uas ntau tus qauv tau zoo heev txawm tias xyoo dhau los. 

Txawm hais tias kev tshuaj xyuas zoo, 1.9 JTD lub cav muaj ntau qhov tsis zoo. Cov no suav nrog cov teeb meem nrog lub hnub ci, qhov tso pa tawm, EGR valve, lossis kev sib kis ntawm phau ntawv. Kawm paub ntau ntxiv txog qhov ua txhaum ntau tshaj plaws. 

Flap Malfunction 

Nyob rau hauv diesel xyaw nrog 4 li qub rau ib lub tog raj kheej, swirl flaps feem ntau ntsia - nyob rau hauv ib qho ntawm ob qhov chaw nres nkoj ntawm txhua lub tog raj kheej. Cov dampers poob lawv txoj kev txav mus los vim muaj kab mob ntawm cov turbodiesel inlet yeeb nkab. 

Qhov no tshwm sim tom qab ib pliag - lub throttle sticks los yog so. Raws li qhov tshwm sim, tus actuator tsis tuaj yeem nrawm mus rau ntau tshaj 2000 rpm, thiab hauv qhov xwm txheej hnyav, lub kaw lus tuaj yeem tawm thiab poob rau hauv lub tog raj kheej. Txoj kev daws teeb meem yog los hloov cov khoom noj manifold nrog ib qho tshiab.

Teeb meem nrog cov pa tawm manifold, EGR thiab alternator

Cov khoom siv manifold tuaj yeem deformed vim qhov kub thiab txias. Vim li no, nws tso tseg rau hauv lub tog raj kheej taub hau. Feem ntau, qhov no yog manifested los ntawm soot accumulating nyob rau hauv lub collector, raws li zoo raws li ib tug hnov ​​tsw ntawm lub tsheb tso pa tawm.

Cov teeb meem EGR yog tshwm sim los ntawm qhov txhaws valve. Tus tsav ces mus rau hauv hom kev kub ceev. Txoj kev daws teeb meem yog hloov cov khoom qub nrog ib qho tshiab.

Lub tshuab hluav taws xob tsis ua haujlwm tshwm sim qee lub sijhawm. Hauv qhov xwm txheej no, nws nres them ib txwm. Feem ntau yog vim li cas yog lub diode nyob rau hauv lub voltage regulator. Yuav tsum tau hloov.

Manual Transmission Malfunction

Thaum lub sijhawm ua haujlwm ntawm 1.9 JTD lub cav, phau ntawv sib kis feem ntau ua tsis tiav. Txawm tias muaj tseeb hais tias nws tsis yog ib qho khoom ncaj qha ntawm lub cav, nws txoj haujlwm yog txuas nrog lub tshuab tsav. Feem ntau, cov bearings ntawm lub thib tsib thiab thib rau lub zog poob. Ib qho cim qhia tias lub kaw lus tsis ua haujlwm zoo yog suab nrov thiab tawg. Hauv cov kauj ruam hauv qab no, lub tshuab xa hluav taws xob tuaj yeem poob kev sib tw thiab lub zog 5 thiab 6 yuav tsum tsis txhob teb.

Lub cav 1,9 JTD puas tuaj yeem hu ua kev ntseeg siab?

Cov kev poob qis no tuaj yeem ntxhov siab heev, tab sis los ntawm kev paub tias lawv muaj, koj tuaj yeem tiv thaiv lawv. Nws yog ib qho tsim nyog sau cia tias, ntxiv rau cov teeb meem saum toj no, tsis muaj kev ua haujlwm tsis zoo thaum lub sijhawm ua haujlwm ntawm 1.9 JTD lub cav, uas tuaj yeem ua rau, piv txwv li, mus rau kev kho dua tshiab ntawm chav tsev fais fab. Vim li no, lub cev muaj zog los ntawm Fiat - tsis muaj kev tsim kho tsis zoo, tuaj yeem piav qhia tau zoo thiab ruaj khov.
