  • Publication number: 20140109882
    Abstract: A method for monitoring the leak tightness of a fuel tank system is provided, the fuel tank system being provided for supplying fuel to a supercharged internal combustion engine. A pressure accumulator is filled from the supercharged intake manifold area of the internal combustion engine. The pressure from the pressure accumulator is transferred to the fuel tank system, which includes in particular the fuel tank and, if necessary, an activated carbon filter. The pressure curve in the closed fuel tank system is observed. A leak in the fuel tank system may be inferred on the basis of the pressure curve, if necessary.

  • Patent number: 8529659
    Abstract: A method is provided for diagnosing the operability of fuel vapor intermediate stores (4), in particular of activated carbon filters, in tank-venting systems with at least one tank (3) and at least one fuel vapor intermediate store (4). In this case an actual change degree of filling of the fuel vapor intermediate store (4) is determined as a consequence of absorption or desorption processes of gaseous hydrocarbons in the fuel vapor intermediate store (4). The actual change in degree of filling is compared with a desired change in degree of filling and, from the comparison, a conclusion about the operability of the fuel vapor intermediate store (4) is drawn.
