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.[1]
The N55 was BMW's first straight-six engine to use a twin-scroll turbocharger. It also won three straight Ward's 10 Best Engines awards in 2011-2013.[2]
Following the introduction of the BMW B58 engine in 2015, the N55 began to be phased out.[3]
BMW S55 engine is a high performance version of the N55, which is used by the F80 M3, F82 M4 and F87 M2 Competition.
Design[edit]
The main differences between the N55 and its N54 predecessor are the use of a single turbocharger, the addition of Valvetronic and the type of fuel injectors. Whilst the N54 used a twin-turbo arrangement, the newer N55 uses only a single twin scroll turbocharger.[4][5]Valvetronic (variable valve lift)[6] is claimed to improve throttle response, low-rev torque, exhaust emissions and to reduce fuel consumption by 15%.[7][6][8] The direct injection system uses solenoid-type injectors, instead of the piezo-type 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.[6]
The exhaust manifold design, called Cylinder-bank Comprehensive Manifold (CCM) by BMW, aims to reduce the pressure fluctuations to reduce throttle lag and exhaust back-pressure.[9] The twin-scroll turbocharger uses 2 sets of exhaust duct to turn 1 turbine wheel, with cylinders 1-3 and 4-6.[10] The engine management system is Bosch MEVD 17.2, and compatible fuels are ROZ (RON) 91-98 octane (minimum RON 95 is recommended),[11][12]
As per the N54, the compression ratio is 10.2:1, the bore is 84.0 mm (3.31 in), the stroke is 89.6 mm (3.53 in) and the displacement is 2,979 cc (181.8 cu in).
