Definitions
- the valve is preferably designed to close the channel at predetermined times (controlled and / or complete).
- no additive is passed through the channel of the exhaust treatment device any more.
- the valve may for example have a movable valve armature which closes the channel in the closed state and releases the channel in the open state.
- the valve armature can be moved, for example, electromagnetically.
- the valve has, for example, an electromagnetic coil which can exert a force on the movable valve armature when an electric current flows through the coil.
- connection region a flow of heat from the injection device through the connection region into an environment surrounding the injection device is reduced in the case of freezing or in the case of cooling of the injection device.
- a heat flow out of the injection device through the outlet region is then greater or greater than the described heat flow beyond the connection region.
- the heat insulation is designed such that the amount of thermal energy stored in the injection device is almost completely discharged through the outlet region into a connected exhaust gas treatment device and / or no significant heat flow is discharged through the connection region into the surroundings of the injection device.
- the injection device is completely encased in plastic.
- the molded plastic casing can be made with additional material, which is applied in some areas to the continuous plastic casing of the injector.
- the outlet region prefferably has at least one heat flow adjusting means designed as a heat conduction structure for the outflow of heat from the injection device into a contactable exhaust gas treatment device.
- the coolant located there can still be liquid because the coolant preferably contains substances that significantly lower the freezing point of the coolant, so that the coolant remains liquid even at very low temperatures.
- the coolant is still liquid at temperatures of less than -20 ° C, more preferably the coolant freezes only at temperatures of less than -35 ° C.
- the coolant is therefore liquid in the coolant channel in the injection device , However, it is not kept in motion in the refrigeration cycle. Nevertheless, due to temperature differences in the coolant, a flow in the coolant in the coolant channel can be induced or induced.
- the Eisscherkompensationselement In order to completely compensate for the increase in volume of the additive (inside the injection device) with as little technical effort as possible, it is advantageous for the Eisscherkompensationselement to arrange where last until liquid additive is present. Since the freezing direction in the injector described here is from the outlet side to the port side, the ice pressure compensating element should be located at the port side. The Eisscherkompensationselement is also particularly well protected from heat on the connection side, which emanates from the exhaust gas treatment device during operation.
- a displaceable fluid line connection can be designed, for example, as a plug which is attached with a displaceable O-ring to an injector or to a valve in the injection device. Even with a displacement of the fluid line connection relative to the injector, the connection between the fluid line connection and the injector through the O-ring is fluid-tight.
- a bias voltage of the fluid line connection can be achieved, for example, by holding the fluid line connection with a tensioned spring in an operating position. As soon as a force triggered by the volume increase of the additive becomes greater than the force exerted by the spring, the fluid line connection shifts from the operating position into an ice compensation position.
