Zambiri za injini ya OM611
Injini ya dizilo ya OM611 ili ndi chitsulo chosungunuka, mutu wamiyala woponyera, jekeseni wamba wa njanji, ma camshafts awiri (ma drive awiri oyenda sitiroko), mavavu anayi pa silinda iliyonse (yoyendetsedwa ndi ma pusher) ndi njira yotulutsa mpweya.

Injini ya OM611 poyambilira inali ndi turbocharger momwe mphamvu yolimbikitsira imayang'aniridwa ndi zinyalala.
Kuyambira 1999, injini ya OM611 yakhala ndi turbine yosinthira ya nozzle (VNT, yotchedwanso variable geometry turbocharger kapena VGT). VNT idagwiritsa ntchito masamba omwe anali panjira yothamanga mpweya, ndikusintha mbali ya masambawo, kuchuluka kwa mpweya womwe umadutsa mu chopangira mphamvu, komanso kuthamanga kwake, kumasintha.
Pamagetsi othamanga kwambiri, pomwe mpweya wopita ku injiniyo unali wotsika, kuthamanga kwa mpweya kumatha kukwezedwa ndikutseka pang'ono masamba, potero kumawonjezera liwiro la chopangira mphamvu.
Ma injini a OM611, OM612 ndi OM613 asinthidwa ndi OM646, OM647 ndi OM648.

Mavuto a OM611
Kudya kangapo... Monga momwe injini zambiri zimayikidwira ku Mercedes, pali vuto la mapiko ofooka pambiri, popeza amapangidwa ndi pulasitiki. Popita nthawi, amatha kusokonekera ndikulowa pang'ono mu injini, koma izi sizimawononga kwambiri. Komanso, dampers izi zikayamba kupindika, mabowo a olamulira omwe dampers amazungulira amatha kuyamba kusweka.
Nozzles... Komanso, kuwonongeka komwe kumakhudzana ndi kuvala kwa ma jakisoni si zachilendo, chifukwa cha zomwe zimayamba kutayikira. Chifukwa chake chitha kukhala chachitsulo komanso chopanda mafuta. Osachepera 60 zikwi. Ndibwino kuti muzitsuka makina ochapira pansi pa jakisoni ndi ma bolts okwera, kuti mupewe kulowa kwa dothi mu injini.
Camshaft pa Wothamanga... Nthawi zambiri, vuto la kugwedeza zombo zazikulu za camshaft limadziwika makamaka pamitundu ya Sprinter. Zingwe za 2 ndi 4 zimasinthidwa. Chifukwa cha kulephera kumeneku chagona pakusakwanira kwa mpope wamafuta. Vutoli limathetsedwa mwa kukhazikitsa mpope wamafuta wamphamvu kwambiri kuchokera kumasulira amakono a ОМ612 ndi ОМ613.

Kukhazikitsa OM611
Njira yofikira kwambiri ya OM611 ndiyo kukonza tchipisi. Zotsatira zake zingapezeke mukangosintha firmware ya injini ya OM611 2.2 143 hp:
- 143 hp. -> 175-177 HP;
- 315 NM -> 380 Nm ya makokedwe.
Zosinthazi sizowopsa ndipo izi sizingakhudze kwambiri gwero la injini (mulimonsemo, simudzawona kuchepa kwa gwero pazomwe ma motors amatha kupirira).
