4Introduction.N57 Engine.HighlightsThe N57 is a logical development from theN47 engine. For instance, the N47 alreadyfeatured rear-mounted chain drive systemdesigned to satisfy future pedestrian impactseverity reduction requirements and a vacuumpump relocated inside the sump.Another modification was the repositioning ofthe auxiliary units on the left-hand side of theengine. By having the auxiliary units all on oneside, space is created on the right-hand side ofthe engine for locating exhaust treatmentcomponents close to the engine. There is alsosufficient space for the Top modelturbocharger assembly (N47 Top engine).It has also been possible to reduce the heightof the cylinder head by 29 mm compared withthe predecessor model. The inlet ports nowrun parallel and the intake system with integralswirl flaps is an ultra-compact design.Below the sound insulation cover on the F01,sufficient space is allowed at the rear for an airintake muffler and the engine-mountedunfiltered and filtered air ducting. Theindividual power options vary in this regardonly in terms of the size of the filter element.In order to minimize the complexity ofapplication adaptations, instead of the enginemounted air intake muffler, the E9x modelsuse the unfiltered air ducting and the vehiclemounted air intake muffler from theM57D30T2 engine.The 3rd-generation common-rail system withan injection pressure of up to 1,800 bar, a newCP4.2 high-pressure pump and piezo-electricfuel injectors complete the fuel-systemmodifications.As on the N47 engine, the exhaust system hasan electric EGR valve flange-mounted on the"hot" side and a bypass in the EGR cooler sothat the EURO 5 emission limits can bereliably complied with. Thus on volumeproduction launch, the N57 engine will alreadymeet the EURO 5 emission requirements notdue to come into force until 01/01/2011.For compliance with the EURO 6 emissionlimits, additional use of an active exhausttreatment system will be necessary.Depending on flywheel weight class (vehicleweight) and resistance to motion, either anNOx-accumulator catalytic converter or anSCR (selective catalytic reduction) systemsupplemented by low-pressure exhaustrecirculation will be used. Those two systemsare explained in the "M57D30T2 US Engine"documentation and, therefore, are notdescribed in further detail at this point.Following on from the 4-cylinderdiesel engine, a new 6-cylinderdiesel engine has now also beenintroduced. After 10 years and twomajor upgrades, the 6-cylinderdiesel engine is now being replacedby an entirely new design, the N57.The N57 engine has manycomponents that have already beenused in volume production on theN47 engine.With even more power and torquecombined with lower fuelconsumption and lighter weight, it isideally equipped to continue thesuccess story.Objectives Increased power and torque Ability to derive performance versions Reduction of CO2 emissions Compliance with EURO 5 and upgradabilityto EURO 6 and LEVII/Bin5 (USA) Reduction of weight and dimensions with aview to compliance with futurerequirements regarding exhaust treatmentand pedestrian impact severity reduction Modular design and use of identicalcomponents from the N47 models.11

4Summary of design featuresVariant structureThe table below summarizes the changesimplemented on the N57 engine. Distinctionsare made in various categories.The basic concept means that the enginecasing components can be developed andproduced according to the same standardsboth for the 4-cylinder and the 6-cylinderdiesel engines. "New development" denotes a technologythat was not used on the predecessorengine.Differentiation is achieved by way ofturbocharging, fuel injection and exhausttreatment systems. "Identical component" denotes acomponent that was designed for the N47engine and is also used on the N57 engine.Thus the N47 engines and the N57 engineshare the following features: "Identical concept" denotes a componentthat is based on the same design concepton the N47 and the N57 engines but whichhas been adapted for the N57 engine. Standardized combustion chamber Same cylinder spacing Same engine height Same attachment arrangements (e.g.gearbox)16Identical component on N47 engineand N57 engine7777Valvegear components77Fuel pump77Fuel filter heater77Fuel injectors and highpressure fuel lines77Identical concept onN47 engine and N57 engineComponentPistons and connectingrodsMain and big-end bearingsNew development Standardized auxiliary units.RemarksOptimized for new generation of dieselenginesDimensioned for the various performanceratings (e.g. N47TOP)Use of reduced-friction and weightoptimized componentsThe fuel pump is a regulated-pressuredesignThe fuel filter heater is controlled by thedigital diesel engine managementNew generation of fuel injectors adapted forthe high injection pressures. The higherperformance and the "Top" line models havepiezo-electric injectors.

The auxiliary unitmounting bracket is identical on all E9xmodels. On the F01 a new mounting bracketwith sliding bushes is used.The auxiliary units are adapted to the vehicleconcerned.Different belt tensioners are used accordingto vehicle model. A two-sided belt is used.New-design components are used for bothengine casing assemblies (N47 and N57engines). On the N47 engine, a bypass valveis fitted in some cases dependent ongearbox version and performance rating. TheN57 engine always has a bypass valve.The same, new-design sensor system isused both on the N47 engine and the N57engine.The crankcase is an entirely new design andemploys an identical concept for bothengines. Rigidity has been increased so as tobe able to meet future requirements as well.A reinforcing plate further increasesstrength. The aluminium crankcase hasthermally joined cast iron cylinder liners. Thecrankshaft main bearing caps are providedwith a raised profile on the joint face.The crankshaft drive system has beenadapted to the higher engine power output.At the same time, however, great emphasiswas placed on lightweight design.17

TheCP4.1 is a single-piston HP pump, the CP4.2a twin-piston HP pump. The high-pressurepumps can generate injection pressures upto 2,000 bar.The high-pressure accumulator is designedfor the high fuel pressures.The latest-generation engine managementis used.
