Abstract

The method involves feeding volatile gas containing. hydrogen emanating from the tank (14) via a filter arrangement (32) in which it is collected. The filter arrangement is subjected to a vacuum to feed the filter material via a induction system (16) of an induction process into an internal combustion engine, whereby the connection between the filter arrangement and induction system is opened and closed by a clocked switching device. A drive signal for the switching device is cross-correlated with a measurement parameter defining the state of the induction system, and a correlation coefficient is evaluated as a diagnostic signal for the tank venting system.
