N55B30M0 Engine: Notes
The 535i Gran Turismo F07 will be launched to the US market in the Spring of 2010. This vehicle uses the N55 engine which is the successor to the N54 engine. Technical updates and modifications make it possible to use only one exhaust turbocharger. The technical data have remained virtually the same - with reduced costs and improved quality.
Innovations on the N55 engine:
- Single exhaust turbocharger (twin scroll type)
- Air-gap-insulated exhaust manifold six into two
- Catalytic converter is located closer to engine
- Direct fuel injection with central injector location, (uses solenoid valve injectors)
- 3rd generation Valvetronic
- Engine mounted Digital Engine Electronics (MEVD17.2 Bosch), integrated into intake system, FlexRay capability
- Lightweight-construction crankshaft
- Characteristic-map-regulated oil pump
- Uniform single-belt drive across all model series
