Die Einspritzdüse erhitzt sich zwar durch die Wärme des Abgases etwas, aber der kontinuierlich die Einspritzdüse durchströmende Kraftstoff nimmt die Wärme der Einspritzdüse auf und transportiert diese aus der Einspritzdüse heraus. In vorteilhafter Weise wird dabei die Einspritzdüse durch den Kraftstoffstrom in der Einspritzdüse gekühlt.The inventive device is characterized by an injection nozzle, according to a first embodiment according to claim 1 in addition to the fuel inlet has a cooling return, wherein fuel is the fuel inlet and the cooling return in the operation of the internal combustion engine flows continuously. In a second embodiment according to claim 2, in addition to the fuel inlet, a cooling inlet and a cooling return provided the fuel being the cooling inlet and the cooling return in Operation of the internal combustion engine flows continuously. The injector is over a Dosing unit to a low-pressure circuit of an injection system, preferably a diesel injection system, connected. The injector is an exhaust system assigned to the internal combustion engine. The injector injects by means of a valve element provided in a fuel inlet Fuel into the exhaust system, so a particulate filter in the exhaust system downstream to regenerate the injection valve. The injector heated though through the heat the exhaust gas something, but the fuel flowing continuously through the injector takes the heat the injector and transports them out of the injection nozzle. In an advantageous manner Way, the injector is doing through cooled the fuel flow in the injector.
In Ausgestaltung der Erfindung gemäß Anspruch 3 ist der Kraftstoffzulauf zumindest teilweise von einem Kraftstoffsammelnden Raum umgeben, wobei Kraftstoff über den Kühlzulauf in den Kraftstoffsammelnden Raum einströmt und über den Kühlrücklauf aus dem Kraftstoffsammelnden Raum ausströmt.

Übersteigt der von der Dosiereinheit eingestellte Druck des Kraftstoffes im Kraftstoffzulauf einen vorgegebenen Wert, so öffnet das vorzugsweise federbelastete Ventilelement selbsttätig und der Kraftstoff wird in das Abgassystem der Brennkraftmaschine abgespritzt. Vorteilhafterweise ist hierzu kein Aktor zur Betätigung der Einspritzdüse nötig.In Further embodiment of the invention according to claim 4 opens the Valve element automatically by the pressure of the fuel in the fuel inlet. The fuel is over the Hosed valve element in the exhaust system. The dosing unit controls the fuel flow in the fuel supply to the valve element. exceeds the pressure of the fuel set by the dosing unit in Fuel inlet a predetermined value, so opens the preferably spring-loaded Valve element automatically and the fuel is introduced into the exhaust system of the internal combustion engine hosed. Advantageously, this is not an actuator for actuating the injection necessary.
In weiterer Ausgestaltung der Erfindung gemäß Anspruch 5 ist der Kühlrücklauf der Einspritzdüse über einen Wärmetauscher mit dem Niederdruckkreislauf verbunden. Der Kraftstoff strömt aus dem Kühlrücklauf der Einspritzdüse zunächst in den Wärmetauscher, der den erhitzten Kraftstoff aus der Einspritzdüse kommend abkühlt, bevor der Kraftstoff aus dem Wärmetauscher wieder in den Niederdruckkreislauf des Einspritzsystems zurückströmt. Von Vorteil ist, dass der Niederdruckkreislauf des Einspritzsystems nicht mit erhitztem Kraftstoff belastet wird bzw. es zu einer Erwärmung des Kraftstoffes im Niederdruckkreislauf kommt.In Another embodiment of the invention according to claim 5, the cooling return of Injection nozzle over one heat exchangers connected to the low pressure circuit. The fuel flows out of the cooling return of the injection first in the heat exchanger, which cools the heated fuel coming from the injector before the fuel from the heat exchanger flows back into the low pressure circuit of the injection system. Advantageous is that the low-pressure circuit of the injection system is not with heated fuel is charged or it is a heating of the Fuel comes in the low pressure circuit.
