Abstract

See full text

A fluid system of an internal combustion engine is provided with a heating device in a heating chamber. An electric heating element of the heating device is arranged between two holding bodies such that the heating element electrically and thermally contacts a contact section of at least one of the holding bodies. The heating chamber has an inner volume region between the holding bodies and at least one outer volume region arranged on an outer side of the holding bodies. The inner and outer volume regions allow fluid to flow through. The inner volume region has an enlarged section with a first spacing measured between the holding bodies. The holding bodies have a second spacing measured in a region of the contact section. The first spacing is greater than the second spacing at least at a circumferential side of the contact section facing the enlarged section.
