Abstract
The invention relates to a method for limitation of at least one controllable operating parameter that can cause ageing of at least one component or one material in connection with an engine. The method includes the steps of determination of a maximum limit value allowed regarding the operating parameter and control of the engine so that the limit value is not exceeded, thereby limiting ageing of the component or material. The invention includes continuous determination of a measure that corresponds to the degree of impairment of the component that depends on ageing, wherein said determination of the limit value is made depending on the measure. The invention also relates to an arrangement for accomplishing this method. By means of the invention, an improved method and arrangement is provided for limitation of ageing of components and materials that, in particular, are arranged in connection with a combustion engine in a vehicle, thereby providing improved fuel consumption, improved emissions and improved performance of the vehicle.
