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.

A hydrogen combustion device including a first plate including a plurality of through holes; a second plate approached to the first plate so as to define a chamber between the same plates; a heater of the first plate; an injection system configured to inject hydrogen into the chamber through the holes; and a generator defining a potential difference between the plates so that the hydrogen in the chamber defines an electric arc between the plates.

An engine including an exhaust bypass valve and an intake bypass valve. The exhaust bypass valve is disposed in an exhaust bypass channel connecting an outlet of an exhaust manifold and an exhaust outlet of a turbocharger to each other. The intake bypass valve is disposed in an intake bypass channel connecting an inlet of an intake manifold and an inlet of the turbocharger. An intake pressure sensor detects a pressure of the intake manifold. If an instruction value indicating an upper limit or a lower limit of the valve opening degree of the intake bypass valve is continuously output for a predetermined time or more, an engine control device determines that an abnormality occurs in at least one of the exhaust bypass valve and the intake bypass valve.
