ABSTRACT:
An intake device for a mixture-compressing internal-combustion engine has a heating element for heating the injected fuel downstream of an injection nozzle in the intake channel in order to avoid formation of fuel condensate which is harmful in the exhaust emission. The heating elements are configured in plate form and directed at an angle towards the injected fuel jet such that, on one hand, there is a good heating and, on the other hand, there is a low flow resistance by the heating elements. The plate heating element can be integrated in a flush and heat-insulating manner in the wall of the intake channel. By virtue of the low flow resistance which a plate-like heating element arranged obliquely in the fuel/air mixture flow produces, the heating surface can be made larged and consequently a rapid fuel heating can be achieved.
