- SHED test sealed housing for evaporative determination
- an HC adsorber in the form of a container filled with activated charcoal is integrated into the tank ventilation system.
- the filter Since the filter has only a limited working capacity, it must be regenerated before reaching saturation.
- the regeneration is carried out by the administration of a scavenging air mass flow from the environment through the filter, wherein the air is enriched via the desorption with HC molecules, to then fed controlled the engine combustion.
- DE 10 2007 048 953 A1 describes a method and a device for detecting the loading of an activated carbon filter with hydrocarbons.
- An acoustic input signal from a sound source is fed to the activated carbon filter in such a way that an interaction of the input signal with the activated carbon of the activated carbon is achieved
- Activated carbon filter occurs.
- a result of the interaction is recorded as an acoustic response signal by a sound receiver acoustically coupled to the activated carbon and the loading of the activated carbon filter is determined from an acoustic property of the activated carbon, which is reflected in the acoustic response signal.
- the internal combustion engine with tank ventilation system has an adsorption filter, which has a filter bed and a signal line connected to a central control unit of the internal combustion engine adjustable ultrasonic transmitter in a
- Adsorptionsfiltergebliuse includes, and the adsorption filter is by means of a

- the regeneration valve for releasing the purge line and the adjustable ultrasonic transmitter for emitting sound by means of the central control unit are controlled by processing information about the operating point of the internal combustion engine.
- the sound emitted by the adjustable ultrasonic transmitter can be variably adjusted in terms of amplitude and / or frequency as a function of a loading state of the adsorption filter.
- US 2017/0370306 A1 describes a method and a device for regenerating an adsorption filter.
- the frequency of an ultrasonic excitation can be changed during a flushing process.
- the design of the adsorption filter requires a virtually continuous regeneration in order to meet the legal requirements even under extreme conditions.
- Fog, water passages and condensate can lead to a water entry into the adsorption filter, which leads to a reduction in working capacity.
- the reduction of the capacity of the adsorption filter can be accepted to a certain extent, a reduction beyond that can at the appropriate
- a remaining working capacity of the adsorption filter can be given by the formula:
- V volume of the adsorption filter
- dXWr change of the regeneration density by water (reversible)
- dXKr change of the regeneration density by volatile parts of
- the invention is achieved both by means of a method according to claim 1 and by a device according to claim 8.
- the adsorption filter is subjected to a first ultrasonic excitation over a period of time, wherein the energy input of the first
- Ultrasonic excitation is chosen such that it is sufficient on the one hand to increase the desorption of gaseous hydrocarbon constituents and on the other hand not to significant evaporation of liquid, volatile hydrocarbon ingredients and / or water is sufficient.
- the adsorption filter over a period of time with a second
- Ultrasound excitation applied wherein the energy input of the second ultrasonic excitation is selected such that it is for the evaporation of liquid, volatile
- Hydrocarbon constituents and / or water is sufficient.
- the accumulated deviations give the mass of the liquid volatile hydrocarbon components and on the other hand the difference of the second load minus the load in the new condition of the adsorption filter gives the value of the mass of the irreversible components.
- Hydrocarbon components the value of the mass of water.
- both the gaseous hydrocarbon components and the liquid hydrocarbon volatile components and water can be removed.
- the method according to the invention offers the possibility of determining the value of the mass of the liquid, readily volatile hydrocarbon components, the value of the mass of the irreversible inclusions and the value of the mass of the water in the adsorption filter.
- the method according to the invention can be carried out during regular engine operation (during a journey).
- the value of the mass of the liquid, volatile hydrocarbon components is stored, compared with a threshold value and generates an error message if the threshold value is exceeded.
- Liquid, volatile hydrocarbon constituents should generally not occur. If a retention valve in the tank is defective, sloshing of the fuel can lead to an entry of liquid fuel into the adsorption filter.
- the value of the mass of the irreversible constituents is stored, compared with a threshold value and generates an error message if the threshold value is exceeded.
- the threshold value can be determined experimentally and results from the difference between the working capacity in the new state and the minimum working capacity of the adsorption filter, at which the legal requirements, for example the SHED test, are still met.
- the subject of the error message may be an exchange of the adsorption filter.
- the value of the mass of the water is stored, compared with a threshold value and generates an error message if the threshold value is exceeded.
- the threshold can also be determined experimentally.

- Adsorption filter allows it.
- the energy input of the first ultrasonic excitation is selected such that it is sufficient on the one hand to increase the desorption of the stored gaseous hydrocarbon constituents and on the other hand is not sufficient for a significant evaporation of liquid, volatile hydrocarbon components and / or water.
- Lambda probe observed, i. it checks for measurable
- Hydrocarbon constituents in the regeneration gas above the lambda probe are detectable. The observation can also be used to adapt the degree of loading of the scavenging air.
- step 2 a query is made regarding a change in the mixture reaction during the first ultrasonic excitation.
- step 1 If there is a change in the mixture reaction during the first ultrasound excitation, it is possible either to return to step 1 (see dashed arrow in the figure) to perform a renewed first ultrasound excitation or to go to step 3, in which a message can be generated in that gaseous hydrocarbons are also incorporated in the adsorption filter.
- step 4 a first loading of the adsorption filter is determined.
- step 5 a query is made whether the value of the first load with the value of
- step 6 a message can be generated that the adsorption filter has been completely regenerated and no adsorption of liquid, volatile hydrocarbon components and / or water and / or irreversible components in the adsorption filter present, which can be removed by means of an ultrasonic excitation.
- step 7 the adsorption filter is acted upon by a second ultrasonic excitation over a period of time.
- step 8 a query is made regarding a change in the mixture reaction during the second ultrasonic excitation. If, after the second ultrasound excitation, there is no change in the mixture reaction, a message can be generated in step 9 that no liquid, slightly volatile hydrocarbon constituents are stored in the adsorption filter, which can be removed by means of ultrasonic excitation.
- a second loading of the adsorption filter is determined in step 10.
- step 11 a query is made as to whether the value of the second load coincides with the value of the first load.
- step 12 first, the value of the mass of the liquid, volatile
- Hydrocarbon constituents from the deviations accumulated in step 7 and the value of the mass of the irreversible constituents are determined from the difference of the value of the second load minus the value of the load when new.
- step 7 If the value of the second load does not agree with the value of the first load, then either return to step 7 (see dotted arrow in the figure) to perform a second ultrasonic re-energization, or go to step 13, in which Value of the mass of the water is determined from the difference of the value of the second load minus the value of the first load minus the value of the liquid volatile hydrocarbon components.
