Abstract: A method for controlling a turbocharged hydrogen engine for burning an air-hydrogen mixture having an air-hydrogen ratio ? greater than 1. The hydrogen engine is configured to assume steady operating states and transient operating states, wherein ignition timings are more retarded in the transient operating states than in the steady operating states.

Abstract: A method for operating an internal combustion engine including a combustion chamber which is connectable to a charge air supply and to a supply for fuel. An exhaust gas system receives the combusted air from the combustion chamber and supplies it at least partially to an exhaust gas turbocharger, wherein fuel can be introduced into the exhaust gas system via a metering valve. The method includes: (i) supplying fuel and charge air to the combustion chamber, wherein more oxygen is present in the combustion chamber than can react with the fuel, (ii) igniting the air/gas mixture in the combustion chamber, (iii) discharging the burned-off mixture (exhaust gas) into the exhaust gas system, (iv) supplying fuel to the exhaust gas flowing from the combustion chamber, (v) igniting the fuel in the exhaust gas, and supplying the fuel to the exhaust gas turbocharger.
