Comparison of engine 275 and engine 275 AMG
| Engine 275 | Engine 275 AMG |
|---|---|
| Fuel, ME-SFI [ME] injection and ignition system 2.7.1 (up to about 28.02.06) Fuel, ME-SFI [ME] injection and ignition system 2.7.2 (up to about 01.03.06) |
Fuel, ME-SFI [ME] injection and ignition system 2.7.1 (up to about 28.02.06) Fuel, ME-SFI [ME] injection and ignition system 2.7.2 (up to about 01.03.06) |
| Displacement 5513 cm3 Rated output up to 380 kW (520 HP) and an 800 Nm rated torque |
Displacement increased to 5980 cm3 (stroke +6 mm, hole +0.6 mm) Rated output 450 kilowatt (612 HP), rated torque 1000 Nm (Forged piston, connecting rod, crankshaft and connecting rod bearing made out of optimized materials - lubricating system adapted, oil cooler to vehicle front and in the front wheel well) |
| One turbocharger (Biturbo) per cylinder bank in cast steel. | In each cylinder bank a larger turbocharger (Biturbo) made out of steel casting. (Geometry and heat resistance were adapted to the increased gas flow) |
| The maximum boost pressure is approx. 0.9 bar at sea level. | The maximum boost pressure is approx. 1.5 bar at sea level. |
| Fuel filter with integrated overflow valve approx. 3.5 bar and with installed throttle (approx. 50 liters/hr). | Model 216, 221: In the fuel tank a fuel filter with integral overflow valve, about 4.1 bar, without throttle. Model 215, 220, 230: fuel tank with intank fuel pump (M3/1) (for model 230 up to about 28.02.06), fuel tank with fuel pressure regulating valve approx. 4.1 bar and throttle approx. 50 liters/hour. |
| Fuel pump (M3) with a maximum delivery rate of approx. 245 liters/hr. | Fuel pump (M3) with a maximum delivery rate of approx. 330 liters/hr. |
| Model 215, 220, 230: the fuel pump control unit (N118) actuates the fuel pump by means of a PWM signal. Model 216, 221: electronically regulated fuel supply: the fuel pump control unit is a CAN subscriber and can be diagnosed. Fuel pressure specification from the ME-SFI [ME] control unit (N3/10) to the fuel pump control unit. |
Model 215, 220 and model 230 until around 28.02.06 (N118): the fuel pump control unit () actuates the fuel pump by means of a PWM signal and the intank fuel pump relay (K27/5, K40/8kX) by means of a ground signal. Model 230 from about 01.03.06: intank fuel pump - removed. The fuel pump control unit actuates the fuel pump with a PWM signal. Model 216, 221: electronically regulated fuel supply: the fuel pump control unit is a CAN subscriber and can be diagnosed. Fuel pressure specification from the ME-SFI [ME] control unit (N3/10) to the fuel pump control unit. |
| Low temperature cooler mounted behind the radiator engine cooling. | Large low temperature cooler (with increased cooling power) mounted in front of the radiator engine cooling. |
| Exhaust system with mixing area for the exhaust gases from each cylinder bank and 2 exhaust tailpipes. | Exhaust system without mixing area (separate exhaust duct) and 4 exhaust tailpipes. |
