ABSTRACT:
In the method, the intake air for an internal combustion engine is heated both during the starting and/or warm-running phases by at least one electrically heatable heating element arranged upstream of the air inlet to the internal combustion engine and wherein the heating period for the pre-start is selected on the basis of the temperature of the cooling water of the internal combustion engine and the temperature of the unheated air taken in by the internal combustion engine, and the heating period for the post-start is selected independently of the pre-start heating time and selected solely on the basis of the cooling-water temperature.
