摘要:
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.

摘要:
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.
摘要:
A method for determining cylinder-specific combustion features of an internal combustion engine, the cylinder-specific combustion features being ascertained from a variable which represents the crankshaft speed, especially being ascertained from a signal of a crankshaft sensor or camshaft sensor. The cylinder-specific combustion features include a combustion position of at least one cylinder and/or a torque of the crankshaft.
摘要:
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.
