摘要： A method for the diagnosis of an exhaust gas recirculation system in an internal combustion engine, including providing a pressure difference reading, which gives a pressure difference in an air supply section of the internal combustion engine or a pressure difference over the exhaust gas recirculation system; determining a pressure difference reference value as a function of one or more operating variables of the internal combustion engine; and detecting a fault in the exhaust gas recirculation system as a function of the pressure difference reading and of the pressure difference reference value.

摘要： A method and device for controlling an internal combustion engine in which a first variable characterizing the pressure in the combustion chamber of at least one cylinder in the internal combustion engine is detected by at least one sensor. A second variable is determined on the basis of the first variable. Features which are assigned to different partial injections are obtained by forming the difference within the second variable.

摘要： A method and device for controlling an internal combustion engine. A first variable is predefined on the basis of a signal of a combustion chamber pressure sensor or a structure-borne noise sensor. This first variable characterizes the combustion process in the combustion chamber of at least one cylinder of the engine. A second variable is read from a characteristics map; a manipulated variable for influencing the combustion process is predefinable from this second variable. The characteristics map and/or the second variable read from the characteristics map are adapted as a function of at least one feature which is determined on the basis of the first variable.

摘要： A device and a method for controlling an internal combustion engine, where a first variable characterizing the pressure in the combustion chamber of at least one cylinder of the internal combustion engine is measured by at least one sensor. A second variable characterizing the energy released during the combustion is ascertained from the first variable. When a threshold value of the second variable is exceeded, a third variable characterizing the combustion process is detected.
