Abstract
A fuel injection nozzle is connected to a pump for injecting the fuel and to a fresh air supply for the internal combustion engine. In order to provide an injection device which allows temperature control of the injected media with a simple structure and arrangement in the motor vehicle, the injection device has an electric heating device for heating the fresh air supplied. The heating device is fluidically connected via a first hose section to the inlet side of the fresh air supply and via a second hose section to the internal combustion engine. The heating device has a layered heating block comprising at least one heat-emitting layer and at least one heat-generating layer coupled thereto in a heat-conducting manner. The heat-generating layer includes at least one PTC element and conductor elements abutting opposed sides of the PTC element.
