Abstract

A method is disclosed for injecting a gaseous fuel in an internal combustion engine having a combustion chamber and an inlet valve assigned to the combustion chamber. The method includes determining a torque output of the combustion chamber, specifying a comparative value for the torque output, and determining a difference between the torque output and the comparative value. When the difference is less than a given threshold value, the method reduces a first injection quantity of the gaseous fuel depending on the determined difference, which is injected temporally before the inlet valve is closed. When the difference is greater than the given threshold value, the method increases the first injection quantity of the gaseous fuel depending on the determined difference. Also described is a device which may carry out the method.
