The BMW N55 is a turbocharged straight-six petrol engine that began production in 2009. The N55 replaced the BMW N54 engine and was introduced in the F07 5 Series Gran Turismo.
The N55 was BMW's first straight-6 engine to apply a twin-scroll turbocharger. It also won three straight Ward'southward 10 Best Engines awards in 2011–2013.[1]
Post-obit the introduction of the BMW B58 engine in 2015, the N55 began to be phased out.[2]
BMW S55 engine is a high operation version of the N55 fabricated by BMW M GmbH, which is used past the F80 M3, F82 M4 and F87 M2 Competition/CS.
Design [edit]
The main differences between the N55 and its N54 predecessor are the use of a single turbocharger, the improver of Valvetronic and the blazon of fuel injectors. Whilst the N54 used a twin-turbo organisation, the newer N55 uses only a unmarried twin scroll turbocharger.[3] [4] Valvetronic (variable valve lift)[five] is claimed to improve throttle response, depression-rev torque, exhaust emissions and to reduce fuel consumption by fifteen%.[6] [v] [vii] The direct injection system uses solenoid-type injectors, instead of the piezo-blazon fuel injectors used by its N54 predecessor. The piezo injectors were more expensive and BMW decided they were not worthwhile outside of Europe, because the potential benefits of lean-burn operation could not be fully realised.[5]
The exhaust manifold design, called Cylinder-bank Comprehensive Manifold (CCM) past BMW, aims to reduce the pressure fluctuations to reduce throttle lag and exhaust dorsum-pressure.[8] The twin-scroll turbocharger uses 2 sets of frazzle duct to plow 1 turbine wheel, with cylinders i–3 and iv–6.[9] The engine direction system is Bosch MEVD 17.2, and compatible fuels are ROZ (RON) 91–98 octane (minimum RON 95 is recommended),[10] [11]
As per the N54, the compression ratio is 10.ii:1, the bore is 84.0 mm (3.31 in), the stroke is 89.half-dozen mm (iii.53 in) and the displacement is 2,979 cc (181.8 cu in).
