Injini iMercedes OM611
Okuqukethwe
IMercedes-Benz i-OM611, i-OM612 ne-OM613 bekungumndeni wezinjini zikadizili ezinamasilinda amane, amahlanu kanye ayisithupha, ngokulandelana.
Imininingwane ejwayelekile mayelana nenjini ye-OM611
Injini yedizili ye-OM611 turbo inebhulokhi yensimbi, ikhanda lesilinda, umjovo wesitimela ovamile, ama-camshafts aphindwe kabili (ama-double-stroke chain drive), ama-valve amane nge-cylinder (eqhutshwa ngama-pusher) nohlelo lokukhipha igesi qeda.
Injini ye-OM1997 eyakhishwa ngo-611 ngabakwaMercedes-Benz yaba ngeyokuqala ukusebenzisa uhlelo lweBosch Common-Rail direct injection system (esebenza ngezingcindezi ezifika ku-1350 bar). Injini ye-OM611 ekuqaleni yayifakwe i-turbocharger lapho umfutho wokunyusa wawulawulwa yi-wastegate.
Kusukela ngo-1999, injini ye-OM611 ifakwe i-turbine eguquguqukayo yombhobho (VNT, eyaziwa nangokuthi i-geometry turbocharger eguquguqukayo noma i-VGT). I-VNT isebenzise isethi yamabhande ebisendleleni yokugeleza komoya, futhi ngokushintsha i-engeli yamakhasi, ivolumu yomoya edlula ku-turbine, kanye nezinga lokugeleza, iguquliwe.
Ngezivinini zenjini ephansi, lapho ukugeleza komoya kuya enjinini bekuphansi kakhulu, izinga lokugeleza komoya lingakhushulwa ngokuvala kancane izindwani, ngaleyo ndlela kwandise isivinini sikaphephela.
Izinjini ze-OM611, i-OM612 ne-OM613 zithathelwe indawo i-OM646, i-OM647 ne-OM648.

Izinkinga ze-OM611
Ukudla okuningi... Njengazo zonke izinjini ezifakwe kwaMercedes, kunenkinga yamaphampu abuthakathaka kokuphindaphindwayo kokudla, ngoba enziwe ngepulasitiki. Ngokuhamba kwesikhathi, zingahle ziqhekeze futhi zingene kancane enjinini, kepha lokhu akuholeli emonakalweni omkhulu. Futhi, lapho lawa ma-dampers eqala ukuhlangana, izimbobo ze-eksisi lapho ama-damper ajikeleza kuzo zingaqala ukugqashuka.
Nozzles... Futhi, ukonakala okuhambisana nokufakwa kwama-injector akuvamile, ngenxa yalokho okuqala ukuvuza. Isizathu singaba ngophethiloli owenziwe ngensimbi futhi ongalungile. Okungenani ama-km ayizinkulungwane ezingama-60. Kunconywa ukuthi ubeke amanye ama-washer akhombisayo ngaphansi kwama-injectors namabhawodi akhwele ukuze kugwenywe ukungena kokungcola kungene enjinini.
Sabalalela ku-Sprinter... Imvamisa, inkinga yokugoqa amabombo we-camshaft main iziveza ngqo kumamodeli we-Sprinter. Amalayili we-2 nowesi-4 angaphansi kokushintshaniswa. Isizathu salokhu kungasebenzi kahle sisebenza ngokunganele kwepompo kawoyela. Inkinga ixazululwa ngokufaka iphampu kawoyela enamandla kakhulu kusuka kuzinguqulo zesimanjemanje i-ОМ612 ne-ОМ613.

Ukushuna i-OM611
Inketho yokuvuna ejwayelekile kakhulu ye-OM611 ukushuna kwe-chip. Yimiphi imiphumela engatholakala ngokumane ushintshe i-firmware yenjini ye-OM611 2.2 143 hp:
- 143 h.p. -> 175-177 hp;
- I-315 Nm -> i-torque engu-380 Nm.
Izinguquko aziyona inhlekelele futhi lokhu ngeke kuthinte kakhulu isisetshenziswa senjini (noma kunjalo, ngeke uqaphele ukwehla kwesisetshenziswa kuma-run angakwazi ukumelana nalezi zimoto).
