Izinguquko ezilandelayo zale yunithi yamandla zikhiqizwa ekucushweni okuyisisekelo kwefekthri:
● I-OM 541.926 kanye ne-OM 541.920 – injini enamandla angu-313 hp, ehloselwe ukuqedela amaloli anomthamo ophansi wokuthwala futhi esebenza ezindizeni ezimfushane nezimaphakathi;
● Injini ye-OM 541.922 - 354 hp yokuqedela amaloli asebenza ezimweni ezihlukahlukene;
I-OM 541.923 - 394 hp injini kanye nokusetshenziswa okuphansi kukaphethiloli phakathi kwamayunithi wamandla ochungechunge angama-501;
● I-OM 541.921 kanye ne-OM 541.925 – injini enamandla amakhulu kakhulu ochungechungeni lwe-501 ku-428 hp
Esinye sezici ze-OM501 series motors yi-Telligent electronic system. Iqinisekisa ukusatshalaliswa okuphelele kanye nokujwayela isikhathi somjovo kanye nengcindezi kumapharamitha athile wokulayisha injini. Ngesikhathi esifanayo, uhlelo lunquma ngokuzimela imingcele yesilinda ngayinye ngokwehlukana, enomphumela omuhle ekusetshenzisweni kukaphethiloli kanye nenani lokukhishwa okuyingozi.
Izixazululo zobuchwepheshe zezinjini ze-Mercedes OM 501LA, kanye nesistimu ye-Telligent, ziqinisekisa ukunethezeka kokushayela iloli kanye nokuphendula okusheshayo kumyalo we-pedal.
Ukungalungi kwe-N55B30 injini
Le yunithi ayikubekezeleli uwoyela okungewona owoqobo kanye nama-cokes asheshayo;
Ama-hydraulic lifters, ama-Vanos nama-Valvetronic aphakathi kwabokuqala abahlushwa i-coke;
Kulezi zinjini, uhlelo lokujova uphethiloli oluqondile seluthembeke kakhulu, kodwa kusekuningi ukwehluleka;
Abanikazi abaningi bashintsha ama-injection kaphethiloli namaphampu omjovo ngebanga elingaphansi kuka-100,000 km;
Isizathu esiyinhloko sokulahlekelwa uwoyela lapha ivalvu yokungenisa umoya ye-crankcase.
