Mercedes-Benz M270 cav
Thaum pib ntawm 2011, Mercedes officially luam tawm thawj cov duab ntawm lub tshiab 1.6-liter combustion engine. Qhov no tau ua tiav ntawm Shanghai Auto Show nrog tib lub hom phiaj ntawm kev sim tus cwj pwm ntawm cov neeg siv khoom muaj peev xwm ntawm lub tsheb tshiab W176. Qhov debut ntawm M270, raws li qhov kev xaiv ua haujlwm tseem ceeb tsis yog M266, tau tshwm sim ntawm W246. Lub cav tau nruab nrog lub turbocharger thiab ncaj qha txhaj tshuaj Blue Direct.
txheej txheem cej luam
Lub transversely mounted M270 engine yog nruab nrog ncaj qha txhaj thiab ib tug turbocharger. Lub cev muaj zog txuas nrog lub thawv tshuab nrog ob lub clutches.
Structurely, lub cav sib txawv los ntawm analogues nyob rau hauv ib tug sib sib zog nqus tsim - compact BC yog nrum los ntawm txhuas nyob rau hauv siab. Lub tog raj kheej lub taub hau thiab crankshaft kuj yog ua los ntawm winged hlau. Lub tom kawg rotates nrog kev pab los ntawm plaub counterweights los yog ib tug balancer. Muaj nyob rau hauv 1.6 liter los yog 2 liter versions. Ob lub versions tau txais kev cog lus, ua haujlwm ceev ceev camshaft adjusters.
ICE ncaj qha txhaj tshuaj muab compression ntau dua piv rau cov pa txhaj tshuaj. Raws li, cov efficiency kuj nce. Lub siab yog muab los ntawm lub twj tso kua mis uas muaj peev xwm xa 200 bar. Qhov no yog ib leeg-plunger mechanism nrog ib tug integrated flow sensor. Roj yog muab los ntawm high-pressure kab rau nozzles uas nqa tawm ncaj qha txhaj rau hauv lub chamber. Piezo effect injector, nruab nrog atomizers nrog ntau lub qhov.
BU cav ntawm hom tshiab. Lub voj voog tag nrho txuas nrog kev tswj hwm ntawm KM tus nqi, nws yog kev koom ua ke nrog lub gearbox thiab lwm yam tseem ceeb ntawm lub tsheb. Efficiency yog nce vim lub lightness ntawm lub cav piv rau plaub-lub tog raj kheej units ntawm chav kawm ntawv no thiab tsis muaj kev sib txhuam poob.
Kev hloov kho
M270 tau muab faib ua cov qauv hauv qab no:
- 6 l DE16 AL liab, 102-122 hp Nrog .;
- 6 l DE 16 AL, 156 hp. Nrog .;
- 2 l DE20 AL, 156-218 hp Nrog.
Tag nrho cov fais fab nroj tsuag yog plaub-lub tog raj kheej, nruab nrog balancers, roj twj tso kua mis thiab lub twj tso kua mis. Cov motors siv qhov tseeb Camtronic system nrog 2-theem sib txawv lub sij hawm thiab Blue Direct system. Ib qho txiaj ntsig kev tsim kho tshiab yog siv ntau qhov hluav taws xob hluav taws xob.
Lub nozzles ntawm lub cav no tso cai rau koj mus tsuag roj nyob rau hauv ib tug tshwj xeeb, zoo tshaj plaws txoj kev. Qhov no yuav txo tau lub sij hawm thiab qhov zoo ntawm combustion ntawm roj av. Tsis tas li ntawd, kev sib xyaw ua ke ntawm cov roj sib txuas tau yooj yim los ntawm kev siv ntau qhov hluav taws xob, nrog rau tus nqi ntawm 4 tawm ib millisecond.

| Oleg | Mileage 145000, pib quaj me ntsis, ntawm idle - mus chirp. Hauv qhov no, cov lus nug tshwm sim. 1. Cov peev txheej ntawm lub cav m270 yog dab tsi, nws tuaj yeem mus ntev npaum li cas nrog kev ceev faj thiab kev saib xyuas zoo? 2. Dab tsi yog qhov peev txheej ntawm lub sijhawm sib txuas? |
| Macleod | Koj xav tau ib tug tshwj xeeb MB scanner kom paub cov saw stretch. Tk normal yuav tsis qhia qhov no. Txawm tias hydraulics los yog saw chirped. Cov saw saw hlau yog nyob rau nruab nrab 150-200tkm, nyob ntawm qhov zaus ntawm kev hloov roj. |
| Consta | Koj puas tuaj yeem piav qhia txog qhov tsis txawj ntse ntawm kev sib txuas ntawm cov saw stretch thiab roj hloov lub sijhawm? ... |
