<p>The invention relates to a method for limitation of at least one controllable operating parameter which can cause ageing of at least one component (17; 19; 20) or one material in connection with an engine (1), comprising determination of a maximum limit value allowed (T2; Ta, Tb, Tc; n1) regarding said operating parameter (T; n) and control of the engine (1) so that said limit value (T2; Ta, Tb, Tc; n1) is not exceeded, by means of which ageing of said component (17; 19; 20) or material is limited. The invention is characterized in that it comprises continuous determination of a measure (F) which corresponds to the degree of impairment of said component (17; 19; 20) which depends on ageing, wherein said determination of said limit value (T2; Ta, Tb, Tc; n1) is made depending on said measure (F). The invention also relates to an arrangement for accomplishing said method. By means of the invention, an improved method and arrangement is provided for limitation of ageing of components and materials which in particular are arranged in connection with a combustion engine in a vehicle, which provides an improved fuel consumption, improved emissions and an improved performance of the vehicle.</p> |
