摘要： The invention relates to a method for determination (26, 27, 28) of temperature values (T1M; T2M) in the material of at least one component (3; 8) provided in association with or inside a combustion engine (1), comprising: detection (25) of data representing predetermined variables of the operating conditions of the engine (1) and the vehicle, derivation of said temperature values (T1M; T2M) dependent upon said variables, whereby control (33; 40; 46) of the thermal load of the engine (1) may be performed dependent upon at least said temperature values (T1M; T2M). The invention is characterised in that said temperature values (T1M; T2M) are derived dependent upon the thermal inertia inherent in said component (3; 8) when changing the rotational speed and/or the load of said engine (1). The invention also relates to a device for such determination of temperature values. The invention provides an improved control of a combustion engine, entailing a reduction of the fuel consumption at high speeds and loads, but without causing the thermal load of certain components to exceed predetermined limit values.
