Abstract: A device and a method for controlling and/or regulating an internal combustion engine, in particular an internal combustion engine having direct injection. A regulation adjusts a combustion state variable, that characterizes the combustion state, to a setpoint value. A control and/or a regulation influences a torque variable that characterizes the torque of the internal combustion engine and/or the noise variable that characterizes the noise of the internal combustion engine, using a control variable.

Abstract: A device and a method for controlling an internal combustion engine, in which, based on a signal that characterizes the vibrations of an internal combustion engine, at least one feature is determined and used to regulate and/or control operating parameters of the internal combustion engine. In order to generate the feature the signal of a sensor is filtered. Filtering selects low-frequency components of the signal.

Abstract: A method and a device for controlling an internal combustion engine are provided, in which method and device a deviation value is determined based on the comparison of a variable characterizing the combustion process in at least one cylinder with a corresponding setpoint value for this variable. Based on the determined deviation value, a first manipulated variable of a first actuator for influencing the start of activation is adjusted. Furthermore, based on the first manipulated variable, a second manipulated variable of a second actuator for influencing the air mass is adjusted.

Abstract: An internal combustion engine has a plurality of cylinders which are arranged in two rows, two exhaust-gas turbochargers which are driven in each case by the exhaust gases from the cylinders of a cylinder row, and exhaust-gas recirculation. Two exhaust-gas discharge lines branch off, upstream of the respective exhaust-gas turbocharger, part of the exhaust gases from the cylinders of a cylinder row to be recirculated and supply this part to a common recirculation line. By way of the common recirculation line, the exhaust gases to be recirculated are supplied, downstream of the exhaust-gas turbochargers, to an air supply. At least one valve, which serves as an exhaust-gas recirculation valve and by which the quantity of recirculated exhaust gases can be set, is provided. The valve has a stop by which a communicating connection made between the two exhaust-gas discharge lines can be shut off.
