Injini ya Mercedes M112
Zamkatimu
Injini ya Mercedes M112 ndi injini yamafuta ya V6, yomwe idayambitsidwa mu Marichi 1997 mu E-kalasi kumbuyo kwa W210 (Injini W210). Iye m'malo injini M104.
Mfundo zambiri
Injini ya M112 imagwirizana kwambiri ndi M8 V113. Nthawi zambiri, adapangidwa pamalo omwewo opanga ndipo ali ndi magawo ambiri ofanana. Onsewa ali ndi chotchinga chopepuka cha alloy cylinder block chokhala ndi ma liner opangidwa ndi Silitec (Al-Si alloy). Injiniyo ili ndi camshaft imodzi pamzere uliwonse wa masilinda. Pamwamba pa crankshaft pali shaft yozungulira yomwe imazungulira molunjika pa crankshaft pa liwiro lomwelo kuti ichepetse kugwedezeka.
Ma camshafts ndi balancer shaft amayendetsedwa ndi unyolo wodzigudubuza wapawiri. Monga M113, M112 ili ndi mavavu awiri odyera ndi valavu imodzi yotulutsira yamphamvu iliyonse, yomwe imayendetsedwa ndi miyala yopepuka yazitsulo yokhala ndi ma hydraulic slack adjuster.
Kugwiritsa ntchito valavu imodzi yotulutsa kumapangitsa kuti pakhale doko laling'ono lotulutsa utsi motero kutentha pang'ono kumapita pamutu wamphamvu, makamaka ngati injini ikuzizira. Chifukwa chake, chothandizira chimafikira kutentha kwake kofulumira. Izi zimathandizidwanso ndi zocheperako zazitsulo zazitsulo zokhala ndi makoma awiri, zomwe zimatenga kutentha pang'ono.
Chipinda chilichonse choyaka moto chili ndi mapulagi awiri kumanja ndi kumanzere kwa valavu yotulutsa utsi. Kapangidwe ka mavavu ndi mapulagi ndi ofanana. Chifukwa cha poyatsira kawiri, kutentha kwa pisitoni kumawonjezeka, kumakhazikika ndi ma nozzles amafuta, kubaya mafuta amafuta kuchokera pansi mpaka pamutu wa pisitoni.
Injini ya M112 idapangidwa ndi kuchuluka kwa malita 2,4 mpaka 3,7. Tiona kusintha kwake mwatsatanetsatane pansipa.
Mu 2004, M112 idasinthidwa Injini ya M272.

Mavuto a injini ya Mercedes M112
Vuto lalikulu la injini iyi ndikudya mafuta, chifukwa cha zifukwa zingapo:
- makina oyendetsera mpweya wa crankcase adatsekedwa, mafuta amayamba kufinya kudzera mu gaskets ndi zisindikizo (kudzera m'machubu zopumira za mafuta, mafuta amayambiranso kulowerera m'malo olowera);
- kusinthana mwadzidzidzi kwa zisindikizo zamatayala;
- avale zonenepa ndi mphete zotsalira mafuta.
M'pofunikanso kuyang'anira kutambasula kwa unyolo (chinthu cha makilomita pafupifupi 250 zikwi). Ngati muwona mu nthawi, ndiye kuti m'malo unyolo (pali awiri a iwo) ndalama kuchokera 17 mpaka 40 zikwi rubles, malingana ndi mtengo wa zida zosinthira. Ndizoipa kwambiri ngati muphonya nthawi yovala - pamenepa, nyenyezi za camshaft ndi tensioner tensioner zimatha, motero, kukonzanso kudzakhala kokwera mtengo kangapo.
Kutulutsa M112
Kuyika katunduyo mwachilengedwe M112 poyamba sikuthandiza, chifukwa kuwonjezeka kwakukulu ndi bajeti yocheperako sikungapezeke, ndipo kusintha kwakukulu kumawononga ndalama zambiri kotero kuti ndikosavuta kugula galimoto yokhala ndi injini ya compressor kale.
Komabe, pali zida za kompresa zochokera ku kampani ya Kleemann, zopangidwa makamaka chifukwa cha injinizi. Mukakhazikitsa zida + za firmware, mutha kufika pa 400 hp pazotulutsa. (pa injini ya malita 3.2).
