Abstract: 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 p1 equals the second gas pressure p2. 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.

Abstract: A method is provided for operating a spark ignition internal combustion engine with an ignition angle adjustment by a control unit and with an exhaust gas turbocharger with a turbine and a compressor and, wherein a throttle valve is provided in an intake air manifold between the compressor and the internal combustion engine. A compressed air device is provided for introducing compressed air into the intake air manifold, including at least one pressure tank and an air injection valve that can be opened by the control unit and is connected to provide gas to the pressure tank for introducing compressed air into the intake air manifold between the throttle valve and the internal combustion engine. A first gas pressure is measured in the intake air manifold between the compressor and the throttle butterfly and a second gas pressure is measured between the throttle valve and the internal combustion engine. The throttle valve can be controlled or regulated by the control unit.
