A method for operating an H2 internal combustion engine (), wherein at least one catalytic converter () for converting an exhaust gas of the H2 internal combustion engine () is arranged in an exhaust gas system () downstream of the H2 internal combustion e...

The method involves computed a filling from an induction pipe pressure in an induction pipe model. A deviation of a detected lambda value from an anticipated value for the injected fuel mass and predicted filling and a difference between the predicted fill...
