Abstract
Embodiments for an engine system are provided. One example internal combustion engine having at least one cylinder head and at least two cylinders, in which each cylinder has at least one inlet opening for the supply of combustion air into the cylinder, comprises an intake line leading to each inlet opening, an overall intake line where the intake lines of at least two cylinders merge, such that a distributor junction point is formed, and a heating device arranged in the overall intake line which has at least one strip-like heating element, a first narrow side of a cross section of which faces toward intake combustion air flow, wherein the heating device is arranged adjacent to the distributor junction point at which the intake lines merge to form the overall intake line, a spacing between the heating device and the distributor junction point being smaller than the diameter of a cylinder.
