Abstract
In multi-valve engines, a partition wall dividing the intake channel into inlet-valve channels as an evaporation element in the intake channel of a cylinder head of an internal-combustion engine for improving the fuel-mixture formation and consequently for reducing the emission of hydrocarbons. The partition wall is electrically heated by a heating bar and is subjected to fuel substantially tangentially from a fuel injection located at the intake channel. As a result of this configuration, the flow behavior of the mixture is optimized in terms of the installation of evaporation elements in the intake channel, and an improved transmission of heat to the mixture and a homogeneous mixture formation are achieved. In addition, sealing problems between the intake channel and the surroundings are solved in a simple way.
