Subaru Impreza cav
Txheem
Tus qauv uas cov kiv cua feem ntau koom nrog kev ua kis las yog Subaru Impreza. Ib txhia xav tias nws yog ib tug qauv ntawm pheej yig tsis zoo saj, lwm tus - qhov kawg npau suav. Txawm li cas los xij, duality ntawm cov ntsiab lus ntawm kev pom tsis yog qhov kev txiav txim siab tseem ceeb uas lub legendary sedan muaj lub cim tshwj xeeb.
Qhov debut ntawm thawj tiam Impreza (wagon thiab sedan) coj qhov chaw nyob rau hauv 1992. Ob xyoos tom qab, tus qauv coupe tau nthuav tawm rau lub tsev hais plaub ntawm cov neeg tsav tsheb, txawm tias nyob rau hauv ib qho kev txwv ntau. Hauv Subaru lineup, Impreza tau ceev nrooj nyob ntawm qhov khoob khoob uas tsim los ntawm Justy thiab Legacy versions.
Tus tsim yog raws li lub shortened platform ntawm lub predecessor - yav tas los hais "Legacy". Thaum pib, lub hom phiaj tseem ceeb ntawm txoj haujlwm no yog los tsim lub tsheb tsim khoom - tus neeg koom nrog "hauv paus" thiab, tej zaum, tus yeej ntawm WRC ntiaj teb kev sib tw. Raws li qhov tshwm sim, lub tsheb ci ntsa iab thiab tsis zoo li qub tau tshwm sim, qhov txawv txav ntawm tus kheej uas tau muab rau nws nrog kev lees paub dav ntawm cov neeg yuav khoom.

Cov tsheb tau nruab nrog boxer plaub-lub tog raj kheej xyaw ntawm EJ hloov kho nyob rau hauv ntau yam versions. Yooj yim "Impreza" versions tau txais 1,6-liter "EJ16" thiab 1,5-liter "EJ15". Sab saum toj-ntawm-tus-kab variations, branded "Impreza WRX" thiab "Impreza WRX STI", tau nruab nrog turbocharged "EJ20" thiab "EJ25", feem. Ntawm cov qauv tsis muaj zog ntawm peb tiam, ib thiab ib nrab litre EL15 fais fab chav tsev lossis ob-liter boxer diesel cav tau teeb tsa.
Qhov thib plaub version ntawm Subaru Impreza yog "tub rog" nrog 2-liter "FB20" thiab 1,6-liter "FB16", thiab kev hloov kho kev ua si ntawm lub tsheb - "FA20" (rau "WRX") thiab "EL25" / "EJ20" ("WRX STI") raws. Kom meej meej cov ntaub ntawv no tau nthuav tawm hauv cov lus 1-5.

Технические характеристики
Raws li tau pom los ntawm Table 1, qhov kev xaiv ntawm powertrains rau Impreza yog incredibly nplua nuj thiab ntau yam. Txawm li cas los xij, ntawm qhov tseeb connoisseurs ntawm cov qauv no, cov motors tau nruab rau sab saum toj versions ntawm WRX thiab WRX STI tshwj xeeb tshaj yog nyiam. Nws tau hais los ntawm qib siab ntawm kev ua tau zoo ua ke nrog lawv cov kev tshwj xeeb thiab kev ua haujlwm. Txhawm rau nkag siab txog kev hloov pauv ntawm Impreza powertrains, xav txog ntau yam qauv: ob-liter EJ20E (135,0 hp) ntawm thawj tiam, 2,5-liter EJ25 (170,0) ntawm tiam thib peb thiab 2,0-liter EJ207 (308,0 XNUMX hp) ) tiam plaub. Cov ntaub ntawv tau nthuav tawm hauv lub rooj.

Tsim nta thiab cov teeb meem raug
Lub hwj chim units tau nruab rau ntawm lub tsheb Impreza, zoo li txhua txoj hauv kev, muaj cov yam ntxwv tsis muaj zog tshwj xeeb rau nws:
- Hauv yuav luag txhua qhov kev hloov kho ntawm EJ20, sai dua lossis tom qab lub khob yuav tshwm sim hauv plaub lub tog raj kheej. Yog vim li cas rau nws qhov tshwm sim yog qhov tsis zoo ntawm qhov tsim ntawm lub tshuab cua txias. Qhov tseem ceeb tshaj plaws yog lub sijhawm ntawm lub khob. Qhov kev tshwm sim luv luv ntawm cov tsos mob no tsis pub dhau 3 feeb tom qab pib yog qhov xwm txheej tsis tu ncua, thaum 10-feeb tapping ntawm lub cav uas muaj cua sov zoo yog ib qho harbinger ntawm kev rov kho dua tshiab.
- Sib sib zog nqus zaum ntawm piston rings, pib nce kev siv roj (hauv versions nruab nrog lub turbocharger).
- Ntxiv hnav thiab ua si ntawm camshaft ntsaws ruaj ruaj thiab valve npog ua rau lubricant to. Kev tshem tawm tsis tu ncua ntawm qhov teeb meem no yuav ua rau poob ntawm cov roj siab hauv lub cev thiab, vim li ntawd, roj tshaib plab ntawm lub cav.
- EJ25 lub zog hluav taws xob muaj cov phab ntsa nyias nyias piv rau lwm cov qauv siv hluav taws xob sab hauv, uas ua rau muaj kev pheej hmoo ntawm overheating, lub tog raj kheej lub taub hau deformation thiab gasket to.
- Kev hloov kho EJ257 thiab EJ255 feem ntau "tshem" los ntawm kev xa cov kab.
- FB20s yog ib qho tseem ceeb rau catalytic vulnerabilities vim siab rhiab heev rau roj theem thiab roj zoo. Tsis tas li ntawd, cov cav tsim ua ntej xyoo 2013 feem ntau muaj qhov tsis xws luag hauv lub tog raj kheej thaiv.
Cov peev txheej thiab kev ntseeg siab
Lub ntsiab zoo ntawm Subaru Impreza fais fab nroj tsuag yog zoo heev tshuav nyiaj li cas, siab zog, me me vibration uas nrog rau cov txheej txheem ua hauj lwm, thiab ib tug ntev kev pab cuam. Kev xyaum qhia tau hais tias feem ntau ntawm cov combustion engine nruab rau ntawm lub Impreza tsis muaj ib tug loj overhaul ntawm 250 - 300 txhiab kilometers.
Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias nqe lus no tsis siv rau turbocharged sports tsheb cav. Tag nrho cov kev hloov kho ntawm cov chav nyob no yog ua nyob rau hauv lub hom ntawm intensive loads, feem ntau ua rau ib tug bulkhead tom qab 120 - 150 txhiab mileage. Kuj tseem muaj cov teeb meem nyuaj tshwj xeeb thaum kho lub cev muaj zog yog technically tsis yooj yim sua.
Qhov siab tshaj plaws ntawm kev ntseeg siab yog muaj los ntawm cov chaw tsim hluav taws xob, lub ntim ua haujlwm uas tsis ncav cuag ob litres: EJ18, EJ16 thiab EJ15. Txawm li cas los xij, ob-liter cav yog nrov dua vim tias lawv muaj zog dua.
Raws li cov engineers - cov neeg tsim khoom ntawm Subaru kev txhawj xeeb, FB series qauv tau txais txiaj ntsig nrog cov peev txheej nce los ntawm ib feem peb.
Hauv kev xaus - qhov tshwm sim ntawm ib qho ntawm cov kev tshawb fawb ntawm cov kws tshaj lij thiab cov kiv cua ntawm Subaru Impreza tsheb, tsim los txiav txim siab lub cav zoo tshaj plaws. Qhov feem pua ntawm qhov kev ntsuam xyuas siab tshaj plaws tau txais los ntawm ob-liter SOHS cav: EJ20E, EJ201, EJ202.
