A method for controlling an electronically actuated valve is described. An ignition signal for a combustion engine is received. The ignition signal is filtered. A control pulse for controlling an electronically actuated valve is generated based at least on the filtered ignition signal. The electronically actuated valve may control the release of compressed gas.

A fresh gas supply device for an internal combustion engine having an exhaust gas turbocharger includes a charge air inlet for taking in a compressed charge air flow from the exhaust gas turbocharger; an outlet which is connected to the charge air inlet via a valve section, said valve section being closed in a closed position by at least one flap valve which can be pivoted, preferably, about a flap rotational axis; an adjusting device which is coupled to the at least one flap valve for adjusting the same in the closing direction; and a compressed air inlet for taking in compressed air into the outlet. The compressed air inlet is arranged such that the compressed air is directed into a compressed air flow in the direction of the valve section to the at least one flap valve. A corresponding method for operating the fresh gas supply device is provided.

A method for operating an internal-combustion engine includes increasing a torque demand, controlling a throttle valve, opening an air injection valve and continuously measuring first and second gas pressures with an electronic control unit. The method also includes closing the throttle valve, measuring a first gas mass flow, retarding an ignition angle, and closing the air injection valve. In the method the throttle valve is opened with the control unit when the first gas pressure p.sub.1 equals the second gas pressure p.sub.2. The method also includes continuously controlling the fuel system with the electronic control unit to have a stoichiometric fuel/air ratio of the internal combustion engine being constantly combusting in the internal combustion engine.
