<p>A method and a system are provided to prevent the turbine of a turbo charger of a combustion engine adapted to power a motor vehicle from over speeding. The engine control system is adapted to control the controllable turbine to a state acting to reduce the turbine speed, in a second step to control the fuel feed to the engine to a reduced fuel feed when the turbine speed reaches a high turbine speed level, and finally turning off the fuel feed when the turbine exceeds a third turbine speed level. Hereby, a turbine over speed protection is achieved.</p> |
