BMS-X engine management system
A pioneer in electronic engine management
The new BMW six-cylinder is equipped with what is currently the most advanced digital engine management system on the market (BMS-X = BMW engine control X). The most important features are fully-sequential, cylinder-specific fuel injection for six cylinders, rapid processing of comprehensive sensor signals using the latest microelectronics, a compact layout, low weight and self-diagnostics. As a result, BMW Motorrad is further enhancing the pioneering role in electronic engine management it has held for a long time now.
The alpha-n-based engine management with torque interface takes into account a multitude of influencing factors. It enables a targeted torque output and engine operation to be sensitively adapted to the widest variety of boundary conditions.
The basis for this engine management is the quantity of intake air, which is determined indirectly via the aperture angle and the rotational speed. The engine control system forms individually coordinated values for injection quantity and ignition time using additional engine and environmental parameters (including engine temperature, air temperature, ambient air pressure) together with the characteristic maps and correction functions stored. The fuel type is specified as Super lead-free, i.e. at least 95 octane.
