Ib qho zoo tshaj plaws 5-lub tog raj kheej turbodiesels los ntawm Swedish lub tuam txhab Volvo. Tsim los siv rau hauv tsheb ntawm peb tus kheej ntau lawm. Lub ntim ua haujlwm yog 2,4 litres, qhov sib piv compression nyob ntawm qhov kev hloov kho tshwj xeeb.

Hais txog motors D5 thiab D3

D5 cav

Nws yog noteworthy tias tsuas yog 5-lub tog raj kheej diesel units yog ib tug tshwj xeeb txoj kev loj hlob ntawm Swedish kev txhawj xeeb. Lwm lub cav, xws li 4-lub tog raj kheej D2 thiab D4, tau txais los ntawm PSA. Vim li no, qhov tom kawg yog, qhov tseeb, ntau dua nyob rau hauv 1.6 HDi thiab 2.0 HDi hom.

Lub ntim ua haujlwm ntawm diesel "tsib" ntawm D5 tsev neeg yog 2 thiab 2,4 litres. Thawj pab pawg yog sawv cev los ntawm D5204T lub cev muaj zog, qhov thib ob - los ntawm D5244T tau piav qhia. Txawm li cas los xij, lub npe D5 tsuas yog muaj nyob hauv cov qauv muaj zog ntawm tsev neeg no, lub zog ntawm ntau tshaj 200 hp. Nrog. Cov tshuab seem feem ntau raug xa mus rau hauv kev lag luam ua lag luam li D3 lossis 2.4 D.

Kev tuaj txog ntawm hom D3 feem ntau yog cov xov xwm tseem ceeb. Ntxiv rau qhov tseeb tias piston stroke raug txo los ntawm 93,15 mus rau 77 hli nrog lub tog raj kheej txoj kab uas hla sab laug zoo li ua ntej, lub ntim ua haujlwm ntawm chav tsev raug txo - los ntawm 2,4 txog 2,0 litres.

D3 tau muaj nyob rau hauv ntau lub versions:

• 136l ua. Nrog .;

zoo

Ntau tus kws tshaj lij pom zoo nrog lub tswv yim tias thawj versions ntawm lub cav no tsis yog li capricious thiab kuj txhim khu kev qha. Nyob rau hauv cov cav no tsis muaj dampers nyob rau hauv lub intake manifold, tsis muaj particulate lim. Electronics kuj tau khaws cia kom tsawg.

Nrog rau kev qhia txog cov qauv Euro-4, turbocharging tswj tau zoo dua. Tshwj xeeb, peb tab tom tham txog qhov tseeb ntawm qhov chaw. Lub tshuab nqus tsev vacuum, uas tau suav hais tias yog qhov nyuaj thiab tsis yooj yim, tab sis yog qhov qub thiab yooj yim heev, tau hloov los ntawm kev siv hluav taws xob siab heev.

2010 tau cim los ntawm kev tshaj tawm ntawm tus qauv Euro-5. Lub compression piv dua yuav tsum tau txo mus rau 16,5 units. Tab sis qhov kev hloov tseem ceeb tshaj plaws tshwm sim hauv lub tog raj kheej taub hau. Txawm hais tias cov phiaj xwm faib roj tau tso tseg tib yam - 20 li qub thiab ob lub camshafts, cov khoom siv cua tau txawv. Tam sim no cov dampers tau ntsia ncaj qha rau pem hauv ntej ntawm ib qho ntawm cov khoom siv hauv lub taub hau. Thiab txhua lub tog raj kheej tau txais nws tus kheej damper. Cov tom kawg, zoo li cov pas nrig, tau ua los ntawm cov yas, uas ua rau muaj kev nkag siab zoo. Raws li koj paub, hlau kaw feem ntau rhuav tshem lub tog raj kheej thaum lawv tawg thiab nkag mus rau hauv lub cav.

Disadvantages

Cia peb xav txog lawv hauv kev nthuav dav ntxiv.

1. Nrog rau kev hloov mus rau Euro-4, lub intercooler - compressed cua txias - tau nkag mus rau hauv qhov kev pheej hmoo. Nws tsis tuaj yeem tiv taus kev ua haujlwm ntev, raws li txoj cai, nws tawg vim qhov hnyav dhau. Cov cim tseem ceeb ntawm nws qhov kev ua haujlwm tsis zoo yog suav tias yog cov roj xau thiab lub cav mus rau hauv hom xwm txheej ceev. Lwm qhov tsis muaj zog hauv qhov kev txhawb zog ntawm D5 lub cav yog cov yeeb nkab txias.
2. Nrog rau kev hloov mus rau Euro-5, lub damper tsav tau yooj yim. Vim lub loads siab nyob rau hauv lub mechanism, ib tug backlash yog tsim nyob rau hauv lub sij hawm, ua rau ib tug mismatch. Lub cev muaj zog tam sim ntawd ua rau qhov no los ntawm kev nres. Lub tsav tsis tuaj yeem hloov tau nyias, nws yuav tsum tau nruab rau hauv kev sib dhos nrog dampers.
3. Cov roj siab regulator ntawm qhov kev hloov kho tshiab tuaj yeem ua rau pib tsis zoo, tsis ruaj khov lub cav ua haujlwm ntawm qhov qis revs.
4. Hydraulic lifters yog rhiab heev rau roj zoo. Tom qab 300th khiav, muaj cov xwm txheej thaum lawv ua tsis tiav thiab ua rau muaj tus cwj pwm tapping. Yav tom ntej, qhov teeb meem no tuaj yeem ua rau kev puas tsuaj ntawm cov rooj zaum hauv lub tog raj kheej lub taub hau.
5. Feem ntau lub tog raj kheej taub hau gasket pierced, vim hais tias gases leaked rau hauv lub txias system, thiab cov tub yees nkag mus rau hauv lub tog raj kheej.
6. Nyob rau hauv 2007, tom qab lwm restyling, tsav ntawm cov khoom siv ntxiv tau txais 3 txoj siv sia. Lub alternator siv thiab lub nro cov menyuam tau ua tsis tau zoo heev, nyob rau hauv uas cov kabmob tuaj yeem npaj txhij txog tawg. Qhov kawg malfunction yooj yim ua rau cov hauv qab no: cov menyuam warped, ya tawm ntawm high engine speeds thiab poob nyob rau hauv lub cover ntawm lub gas faib mechanism. Qhov no ua rau lub sij hawm siv mus dhia, ua raws li kev sib ntsib ntawm cov li qub nrog cov piston.

Ntau tus kws tshaj lij kuj hu lub valve npog ntawm lub cav no teeb meem.

Volvo "tsib" tag nrho yog txhim khu kev qha thiab ruaj khov, yog tias koj saib xyuas nws zoo. Tom qab 150th khiav ntawm lub tsheb, nws yog ib qho tsim nyog yuav tsum tau saib xyuas lub sijhawm siv sijhawm, hloov kho lub twj tso kua mis thiab txoj siv sia ntawm cov khoom sib txuas. Sau cov roj raws sijhawm, tsis pub dhau 10th khiav, nyiam dua 0W-30, ACEA A5 / B5.
