ABSTRACT:
A method operates an improved internal combustion engine by heating the fuel before entry into the cylinder, at least during the cold-start phase of the engine. In order to undertake the heating step in a favorable way, at least areas in the region of an intake valve are irradiated with an electromagnetic radiation of radiation source, and thereby heated without contact. As a result, liquid fuel in the valve region is heated by contact with the areas of the valve region, and condensation of the fuel is at least reduced.
