Injini yakwaMercedes M272
Okuqukethwe
Injini yakwaMercedes-Benz M272 iyi-V6 eyethulwa ngo-2004 futhi isetshenziswa ngawo wonke ama-00s. Kunezici eziningana eziyehlukanisayo neyandulelayo. Ngale njini, isikhathi se-valve esishintshashintshayo sasetshenziswa okokuqala ngqa, kanye nokulawulwa kwe-elekthronikhi kokugeleza kokupholisa (ukufakwa esikhundleni kwe-thermostat emishini). Njengenjini ye-M112, iphinde isebenzisa i-balance shaft efakwe phakathi kwama-cylinder bank ku-cylinder block ukuze iqede ukudlidliza.
Imininingwane M272
Injini ye-M272 inezici ezilandelayo:
- umkhiqizi - I-Stuttgart-Bad Cannstatt Plant;
- iminyaka yokukhululwa - 2004-2013;
- cylinder block impahla - aluminium;
- ikhanda - aluminium;
- uhlobo lwamafutha - uphethiloli;
- idivayisi yesistimu ye-fuel - umjovo kanye nokuqondisa (enguqulweni ye-3,5-litre V6);
- inani lamasilinda - 6;
- amandla, h.p. 258, 272, 292, 305, 250, 270, 265.
Iphi inombolo yenjini
Inombolo yenjini itholakala ngemuva kwekhanda lesilinda esingakwesokunxele, eduze ne-flywheel.
Ukulungiswa kwenjini ye-M272
Injini inezinguqulo ezilandelayo:
Ukuguqulwa | Ivolumu yokusebenza [cm3] | Isilinganiso sokucindezela | Amandla [kW / hp. nge.] | I-Torque [N / m] |
| M272 KE25 | 2496 | 11,2: 1 | 150/204 ngo-6200 | 245 ku-2900-5500 |
| M272 KE30 | 2996 | 11,3: 1 | 170/231 ngo-6000 | 300 ku-2500-5000 |
| M272 KE35 | 3498 | 10,7: 1 | 190/258 ngo-6000 | 340 ku-2500-5000 |
| M272 KE35 | 10,7: 1 | 200/272 ngo-6000 | 350 ku-2400-5000 | |
| M272 DE35 CGI | 12,2: 1 | 215/292 ngo-6400 | 365 ku-3000-5100 | |
| I-M272 KE35 Sportmotor (R171) | 11,7: 1 | 224/305 ngo-6500 | 360 ngo-4900 | |
| I-M272 KE35 Sportmotor (R230) | 10,5: 1 | 232/316 ngo-6500 | 360 ngo-4900 |
Izinkinga Nobuthakathaka
- Ukuvuza kwamafutha. Hlola amapulaki ekhanda lamasilinda epulasitiki - angase adinge ukushintshwa. Lokhu kuyimbangela yokuvuza okuningi okwenzekayo.
- Ama-valve okungena amaningi anephutha. Injini ayizinzile uma ubhekene nale nkinga. Kulokhu, ukushintshwa okuphelele kwe-multifold intake kuyadingeka. Le nkinga yenzeka ezinjinini ngaphambi kuka-2007 futhi ingenye enzima kakhulu ukuyixazulula.
- Ngeshwa, amamodeli amaningi e-Mercedes-Benz E-Class anenjini ye-M272 ekhiqizwa phakathi kuka-2004-2008 anezinkinga nge-balance shafts. Lokhu kungenye yamaphutha avame kakhulu. Lapho amagiya e-balance shaft eqala ukwehluleka, cishe uzozwa umsindo oklabalasayo - njalo uphawu olucacile lwenkinga yenjini. Icala elithile lale nkinga ngokuvamile i-sprocket egqoke ngaphambi kwesikhathi.
Ukuhlwaya
Indlela elula yokwandisa amandla kancane ihlotshaniswa nokushuna kwe-chip. Iqukethe ukukhishwa kwama-catalysts kanye nokufakwa kwesihlungi esinokumelana okuncishisiwe, kanye ne-firmware yezemidlalo. Inzuzo eyengeziwe etholwa umnikazi wemoto kuleli cala isuka ku-15 kuya ku-20 yamahhashi. Ukufaka ama-camshaft ezemidlalo kunikeza amanye amandla angama-20 kuye kwangama-25. Ngokulungiswa okwengeziwe, imoto iba nzima ukuhamba ezindaweni zasemadolobheni.
