Abstract: The present invention relates to a device for generating a dielectric barrier discharge for treatment of an object to be activated with non-thermal atmospheric pressure plasma, comprising a dielectric working chamber which has a wall of a dielectric material and which encloses a working space, wherein a metallization is applied to an outer side of the wall facing away from the working space, wherein the working space is an open volume, and a high-voltage source which is configured to apply a high voltage to the metallization or to the object to be activated when the object to be activated is in the working space. According to a further aspect, the invention relates to a method of treatment of an object to be activated with a non-thermal atmospheric pressure plasma.

Abstract: A method for operating an internal combustion engine having multiple cylinders. A warm-up operation is carried out after the internal combustion engine has been started, during which a speed of the internal combustion engine is limited to a limit value. The limit value is selected during the warm-up operation at least temporarily as a function of a starting temperature of the internal combustion engine.

Abstract: The present disclosure relates to internal combustion engines. The teachings thereof may be embodied in a method for determining a torque reserve for an internal combustion engine during a change of an operating state. The method may include: operating the internal combustion engine in the first operating state; determining a rotational speed; determining a torque; determining an air mass setpoint value based on the rotational speed and the torque in the second operating state; calculating a torque setpoint value depending on the rotational speed and the air mass setpoint value in the first operating state; and determining a torque reserve for the transition from the first operating state to the second operating state using based on the torque and on the torque setpoint value.
