Abstract

A method for heating a fuel flowing through an injection valve into a combustion space of an internal combustion engine includes conveying fuel through ducts of a filter element arranged in the fuel flow, heating walls of the throughflow ducts at least in certain regions along their longitudinal extent, and introducing heat from the walls into the fuel.
