A method for controlling intake throttling for a diesel engine provided with an exhaust gas soot catcher, which also has an intake throttling valve for restricting intake air, thus heating the exhaust gases for purging the soot catcher. The intake throttling valve is controlled by selecting a target opening amount for the intake throttling valve, and by altering the actual opening amount of the intake throttling valve, if substantially different from this target opening amount, in the direction of the target opening amount. The rate of change of the actual opening amount of the intake throttling valve is made to be greater when the difference between the actual opening amount of the intake throttling valve and the target opening amount for the intake throttling valve is greater, and is smaller when the difference between the actual opening amount of the intake throttling valve and the target opening amount is smaller. Apparatus is also described for controlling an intake throttling valve in this manner.
