Tusmo
Mercedes-Benz OM611, OM612 iyo OM613 waxay ahaayeen qoys matoorada naaftada oo leh afar, shan iyo lix dhululubo, siday u kala horreeyaan.
Macluumaad guud oo ku saabsan mishiinka OM611
Mashiinka naaftada ah ee loo yaqaan 'OM611 turbo diesel' wuxuu leeyahay bir bir ah, madaxa silsiladda la tuuray, cirbadeynta tareenka caadiga ah, labalaab dusha sare (laba silsilad silsilad wadata), afar walxaha halkii silsilad ah (oo ay wataan riixayaal) iyo nidaamka dib u soo celinta gaaska.
Mashiinka OM1997 ee la sii daayay 611-kii ee ay soo saartay Mercedes-Benz ayaa ahaa kii ugu horreeyay ee adeegsada nidaamka cirbadeynta shidaalka tooska ah ee loo yaqaan 'Bosch Common-Rail' (oo ka shaqeynaya cadaadis gaaraya illaa 1350 bar). Mishiinka OM611 markiisii hore waxaa lagu qalabeeyay turbocharger kaas oo cadaadiska kor u qaadista lagu xakameeyay qashin-qubka.
Laga soo bilaabo 1999, mashiinka OM611 waxaa lagu qalabeeyay marawaxadaha mashiinka wax lagu beddelo (VNT, oo sidoo kale loo yaqaan 'turbocharger joomatari isbeddel ah ama VGT). VNT waxay adeegsatay aalado farabadan oo lagu taagay wadada socodka hawada, iyo iyadoo la badalayo xagasha garbaha, mugga hawada maraya marawaxadaha, iyo waliba socodka socodka, ayaa isbadalay.
Xawaaraha mashiinka hooseeya, marka hawadu u socoto mishiinku yara yaraa, heerka socodka hawada ayaa lagu kordhin karaa iyadoo qayb ahaan la xiro aaladaha, taas oo markaa la kordhinayo xawaaraha marawaxadaha.
Mashiinnada OM611, OM612 iyo OM613 waxaa lagu beddelay OM646, OM647 iyo OM648.

Dhibaatooyinka OM611
Qaadashada noocyo badan... Sida mashiinno badan oo lagu rakibay Mercedes, waxaa jira dhibaatada furitaanka daciifka ah ee ku jira qaybaha kala duwan ee qaadashada, maaddaama ay ka samaysan yihiin caag. Waqti ka dib, way dillaaci karaan oo qayb ahaan mashiinka geli karaan, laakiin taasi ma keenayso dhaawac culus Sidoo kale, markay qoob-ka-ciyayaashu bilaabaan inay duulaan, godadka dhidibka ee ay biyuhu ku wareegaan ayaa bilaabi kara inay jabaan.
Nozzles... Sidoo kale, burburka la xiriira xirashada irbadaha cirbadaha ma ahan wax aan caadi ahayn, sababta oo ah waxay bilaabaan inay daataan. Sababta waxay noqon kartaa macdan bir ah oo tayo sare leh. Ugu yaraan 60 kun km. waxaa lagugula talinayaa inaad ku bedesho qalabka wax lagu nadiifiyo qalabka duritaanka hoostiisa iyo boolal lagu xiro, si looga fogaado in wasakhda ay gasho mashiinka.
Camshaft on Orod... Badanaa, dhibaatada rogista wiishashka 'camshaft' waxaa si cad loogu muujiyaa moodooyinka Orodka. Khadadka 2aad iyo 4aad waxay ku xiran yihiin wareeg. Sababta cilladan waxay ku timid waxqabadka aan ku filnayn ee mashiinka saliidda. Dhibaatada waxaa lagu xaliyay adoo ku rakibaya bamka saliida ka sii awood badan noocyada casriga ah ОМ612 iyo ОМ613.

Toosinta OM611
Ikhtiyaarka ugufiican ee loo yaqaan 'OM611' waa hagaajinta qashinka. Natiijooyinkee ayaa lagu gaari karaa iyadoo si fudud loogu beddelo qalabka qalabka OM611 2.2 143 hp engine:
- 143 h.p. -> 175-177 HP;
- 315 Nm -> 380 Nm oo Xuddunta ah.
Isbedelada ma ahan kuwo masiibo ah tanina si weyn uma saameyn doonto ilaha matoorka (sikastaba, ma ogaan doontid hoos u dhaca kheyraadka ee orodka ay matoorradan u adkeysan karaan).
