Ekupheleni kuka-2024, elokugcina engqikithini yamaloli amasha eMercedes-Benz Actros angu-500 anikezwa iQembu laseFinéjas emcimbini owawuseWörth. Amaloli akwaMercedes-Benz Actros 1845 LS 4×2 ahlome ngesizukulwane sakamuva senjini kadizili i-OM 471 enamandla angu-330 kW (449 hp), i-MirrorCam, i-Multimedia Cockpit Interactive kanye nezinhlelo zokuphepha zakamuva: Active Brake Assist 6, Active Sideguard Asguard 2 Front Assistad.
Isizukulwane sesithathu se-OM 471, eyethulwa ngo-2022, sinikeza intuthuko ekusebenzeni kahle ngenxa yokuqanjwa kabusha kwenjini. Isibonelo, i-geometry ye-recess ye-piston, idizayini yomjovo womjovo kanye nemingcele yekhanda lesilinda elifanele ukushintshaniswa kwegesi bekungaphansi kwenqubo yokuthuthukisa. Ngale ndlela, isilinganiso sokucindezela se-six-cylinder in-line injini senyusiwe sisuka ku-18.3:1 saya ku-20.3:1, lokhu kuholela ekushiseni okuphumelelayo ngengcindezi ephakeme yokuthungela engama-250 bar.
Esinye sezici ezibaluleke kakhulu ekwandiseni ukusebenza kahle kukaphethiloli ezinjinini zesimanje ezivuthayo zikadizili i-turbocharging optimization. Ngesizukulwane sesithathu se-OM 471, Amaloli akwaMercedes-Benz ethule ama-turbocharger amasha amabili athuthukisiwe futhi akhiqizwa ngaphakathi endlini alungiselwe kahle uhla olubanzi lwezidingo zamakhasimende. Enguqulweni elungiselelwe ukusetshenziswa kahle, kugxilwa ekusetshenzisweni kukaphethiloli okunokwenzeka okuphansi kakhulu—kumiselwe kusengaphambili ukuthi kusetshenziselwe ukuthutha ibanga elide ngenjini elinganiselwa ku-350 kW (476 hp).
Okuhlukile kwesibili kwe-turbocharger yakhelwe ukusebenza okuphezulu namandla okubhuleka injini futhi ilungele ukusetshenziswa emkhakheni we-heavy-duty- kanye nowokwakha onesilinganiso senjini esingafika ku-390 kW (530 hp). Emazingeni okusebenza aphansi namaphakathi e-OM 471, ukonga okukhulu kukaphethiloli uma kuqhathaniswa nesizukulwane sangaphambilini singafika kumaphesenti angu-4, futhi kumazinga okusebenza aphezulu afika ku-3.5%.
Ngaphezu kokuvutha nokushaja kwe-turbo, ukunciphisa ukungqubuzana kuyisici sesithathu esibalulekile sokuthuthukisa ukusebenza kahle kukaphethiloli. Ngale njongo, isizukulwane sesithathu i-OM 471 ine-valve yokulawula ingcindezi kawoyela esanda kuthuthukiswa. Ifakwe ngemuva kwephampu kawoyela yenjini naphambi kwe-thermostat yamafutha. I-actuator kagesi inika amandla izici zokusetshenziswa okulawulwa yimephu kwevalvu yokunciphisa ingcindezi. Ukwehliswa okutholakalayo komfutho kawoyela wenjini kunqunywa ku-matrix eyinkimbinkimbi ecabangela zonke izingxenye zenjini kanye nezidingo zazo ezithile, njengokuthambisa noma ukupholisa. Uwoyela wenjini osanda kuthuthukiswa one-viscosity ephansi uthuthukisa ukulawula umfutho kawoyela—uthuthukisa ukusebenza kahle kukaphethiloli ngaphandle kokunciphisa izikhawu zokushintsha uwoyela noma ukwandisa ukuguga ezingxenyeni zenjini ezithintekile.
I-exhaust gas aftertreatment system, eyavuselelwa ngokuphelele futhi yajwayelaniswa nohlelo olusha lomlilo nokulawula lwe-OM 471, nayo isiza ukuthuthukisa ukusebenza kahle kukaphethiloli. Uhlelo lukhawulela ukucindezela futhi lukhulisa inkomba yokufana kwe-AdBlue, okuholela ku-NO ethuthukisiwex ukuguqulwa kanye nokunciphisa ukusetshenziswa kukaphethiloli. Izinzwa ze-NOx kanye ne-NO evaliwe neguquguqukayox isifunda sokulawula iluphu evaliwe kanye nemodeli yezinga lokushisa le-SCR ebikezelayo yenze ukuzinza kokukhishwayo kuthuthukiswe nakakhulu. Ithobela ngisho nezindinganiso eziqine kakhulu zokukhipha umoya, njenge-Euro VIe, efuna ukuba kube nomkhawulo osebenzayo wesisi esikhipha umoya kuyo yonke impilo yesevisi evamile yemoto ngaphansi kwezimo ezivamile zokusetshenziswa.
I-Finéjas Group yinkampani yezokuthutha yamazwe ngamazwe ezinze eLithuania. Le nkampani yasungulwa ngo-1994, manje isiqashe abantu abangaphezu kuka-3,000 futhi inoxhaxha lwamaloli angu-1,500. Le nkampani igxile ekuthuthweni kwezimpahla ezingenabungozi nezingazweli izinga lokushisa kuma-trailer aseceleni kwekhethini (i-FTL transports, “Full Truck Load”) ngaphakathi kwe-Europe. Iqembu le-Finéjas lithembele kumkhumbi wemikhumbi ofanayo ukuze kuthuthwe imithwalo egcwele yamaloli eYurophu yonke indawo.
