摘要： Devices and methods for knock detection and knock control are described, in which, in addition to the customary component parts, the knock-detection circuit has a filter with switchable filter characteristic. The switchover of the filter characteristic, i.e. the shift, for example, of the mid-frequency of the filter, is carried out taking into consideration specifiable quantities or parameters, for instance, as a function of rotational speed. During the switchover of the filter characteristic, i.e. the shift of the mid-frequency, problems could occur in the knock detection; that is why measures are proposed which carry out the knock detection according to a special knock-detection algorithm during a switchover phase lasting a specifiable time.

摘要： Method of knock control in multicylinder internal combustion engines, with one knock sensor being provided for a group of cylinders, and with a control unit determining and outputting the control quantities for the ignition of the individual cylinders on a selective basis for the cylinders. At least one cylinder, preferably the cylinder(s) sensed best by the knock sensor, is/are selected as the lead cylinder. A knocking event in a lead cylinder causes a retard in the firing for all cylinders of the group, while a knocking event in one of the other cylinders causes a retard in only this one cylinder.

摘要： The method for closed-loop knock control of a internal combustion engine, includes retarding the ignition angle when at least one cylinder knocks and then resetting the ignition angle at a later time. For internal combustion engines with a turbocharger, the method also includes reducing the boost pressure when an ignition-angle limiting value dependent on an exhaust gas temperature is reached, and then increasing the boost pressure again as soon as the ignition-angle limiting value is again crossed due to resetting of the ignition angle. The ignition angle and boost pressure values established are stored as a function of the respective operating condition of the internal combustion engine for adaptive process control and used as starting values when the same engine operating conditions are again reached.

摘要： A method for recognizing a power stroke of each cylinder in a four-stroke engine calls for sensing a parameter of a cylinder in the engine for producing a signal of the parameter, the parameter being selected from the group consisting of pressure and knocking, and comparing the signal with a threshold value for determining whether the signal exceeds the threshold value and thereby is indicative of the cylinder being in a corresponding combustion stroke. In addition to sensing the pressure and knocking of the cylinder, sensing of sound signals from the cylinder is also employed in order to determine power and intake strokes of the cylinders.

摘要： A process for controlling knocking of an internal combustion engine comprises the steps of retarding an ignition angle when a cylinder knocks, resetting the ignition angle by adjusting in the direction of "advance", storing prevailing ignition angle retardation values in an adaptation characteristic diagram which, depending on a size of operating parameters of the internal combustion engine, has subdivided ranges, with one value of an ignition angle retardation determined during operation in an appropriate range and particularly on leaving this range, always being stored, setting the value of the ignition angle retardation as stored for a particular range on changing into this range, and on changing the range, resetting the ignition angle with increased advance adjustment speed until knocking occurs in this range or until a predetermined value of the ignition angle is reached.

摘要： Proposed is a method for adjusting an adaptive characteristics map of an adaptive engine-knock control system and a method for adaptively controlling engine knock, the adaptive characteristics map being defined by at least one operating parameter, the adaptive characteristics map for each operating-parameter range being made up of a precontrol component that characterizes the ambient conditions, and a residual component that results from the engine-knock control, the value of the adaptive characteristics map for each operating-parameter range being given by the sum of the precontrol component corresponding to the specific operating-parameter range, and the residual component corresponding to the specific operating-parameter range. In this context, the adjustment of the adaptive characteristics map is carried out by initially determining if ambient conditions have changed, and by subsequently ascertaining a new precontrol component as a function of the changed ambient conditions for each operating-parameter range, if the ambient conditions have changed, or by holding the precontrol component constant for each operating-parameter range, if the ambient conditions have not changed.

摘要： A knock sensor for indirect or direct fixing to an internal combustion engine has a housing (10) with a pressure sleeve (11) on the outer side of which a piezoceramic disk, a seismic mass (16), the contact disks (14), and the insulating disks (13) are arranged. The insulating disks (13) or the piezoelectrical disk (15) are or is made slightly electrically conductive so that the voltage spikes which occur due to the pyroelectrical effect can be easily eliminated. In this way, faulty measuring and interference can be avoided in the electrical circuit connected to the knock sensor.

摘要： For eliminating acceleration knocking in spark ignition engines, the ignition is retarded when the engine is in dynamic operation by an amount which is optimized for the ambient conditions present at the start of each dynamic operation. The occurrence of knocking of the engine during acceleration is detected, and the amount of change of an engine operation parameter for a next acceleration is adjusted depending on whether or not the knocking during acceleration is occurring.
