Abstract

A method and a device for controlling an internal combustion engine as a function of performance characteristics such as load, engine speed, a corrected value for the intake air temperature being used for the control, the corrected value being obtained from the following formula: EQU TANSK=T1+(TWS-T1)*f where PA1 TANSK=corrected value of the intake air temperature, PA1 T1=value (TANS) of the intake air temperature remote from the internal combustion engine determined by calculation or measured, PA1 TWS=value of the mean temperature of the intake manifold, PA1 f=weighting factor ranging from 0 to 1.
