Mavuto a injini ya M273

Imodzi mwamavuto akulu komanso otchuka a M273 ndi kuvala kwa zida zoyendetsa unyolo wanthawi, zomwe zimabweretsa kuphwanya malo a camshafts pamutu wamanja (wa injini zopangidwa isanachitike Seputembara 2006). Momwe mungazindikire vutoli: Nyali yama injini, ma diagnostic Trouble Codes (DTCs) 1200 kapena 1208 amasungidwa mu gawo loyang'anira la ME-SFI.

Magalimoto omangidwa kuyambira Seputembara 2006 amakhala ndi zida zachitsulo zolimba.

Mafuta kutayikira kudzera pulasitiki yamphamvu mapulagi... Mu injini za Mercedes-Benz M272 V6 ndipo M273 V8s omwe adatulutsidwa Juni Juni 2008 atha kutayikira mafuta (seepage) kudzera m'mapulagi ozungulira apulasitiki kumbuyo kwa mitu yamphamvu.

Panali mitundu iwiri yaziputu zamitundu yosiyanasiyana:

• A 000 998 55 90: mapulagi awiri okulirapo (pafupifupi 2,5 cm m'mimba mwake);
• A 000 998 56 90: pulagi yaying'ono ikulu yowonjezera (ya injini zopanda pampu yopuma).

Kuti mukonze izi, muyenera kuchotsa mapulagi omwe alipo, kuyeretsa dzenje, ndikuyika mapulagi atsopano. Musagwiritse ntchito sealant mukakhazikitsa mapulagi atsopano.

Mu Juni 2008, zida zatsopano zidapangidwa, zomwe sizingachitike chifukwa chamafuta.

Kutha kwa damper regulator pakudya kambiri (kusintha kosiyanasiyana kwamajometri). Chifukwa chokakamizidwa kulowa mpweya wama crankcase, ma carbon deposits amatha kudziunjikira mochulukitsa, zomwe zimalepheretsa kuyendetsa kwamphamvu, komwe kumabweretsa kuwonongeka kwake.

Zizindikiro:

• Osavuta osagwira;
• Kutaya mphamvu (makamaka pama liwiro a injini otsika ndi apakatikati);
• Kuunikira kwa nyali zochenjeza za injini;
• Mauthenga Othandizira Kuzindikira (DTCs) monga P2004, P2005, P2006, P2187 ndi P2189 (Kusintha ma code olakwika a OBD2).

Kukonzekera kwa injini ya Mercedes-Benz М273

Kukhazikitsa injini ya M273 kumayang'ana mumlengalenga ndi kompresa zosankha (zida zonse ziwiri zimapezeka ku Kleemann):

1. Kutali. Kukhazikitsa kwa camshafts ndi gawo la 268, kumaliza kumasulidwa, kudya kozizira, firmware yosinthidwa.
2. Compressor. Kampani ya Kleemann imapereka kompresa ya M273 popanda kufunika kosintha kompiston compressor chifukwa chotsika kwambiri. Ndi kukhazikitsa zida zotere, mutha kufika 500 hp.
