    Abstract: The invention relates to a method for knock regulation in an internal combustion engine, whereby a knock recognition is carried out on the cylinders of an internal combustion engine and, depending, upon the recognition of a knocking combustion in at least one cylinder, an ignition point is retarded by a preset amount. The system comprises at least two electronic evaluation units, each of said electronic evaluator units is attached to at least one cylinder and evaluation of the signals from the knock sensors arranged on the cylinder is performed by the corresponding electronic evaluation unit. Knock recognition and setting the ignition time are achieved by means of a regulator unit and the function of the evaluation unit is monitored. On recognition of a fault of at least one of the electronic evaluation units (30), the at least one cylinder (12, 14) assigned to said electronic evaluation unit is connected to the regulator of at least one cylinder (16, 18) with an intact electronic evaluation unit (32).

    Abstract: The invention relates to a method and a device for error detection or diagnosis, for use in a multicylinder internal combustion engine with a knock sensor. An actual reference value produced from a sensor signal is compared with predetermined upper or lower reference level thresholds for diagnosis purposes. Defective functioning is indicated when the current reference level falls below or exceeds said thresholds in a predetermined manner. The reference levels correspond to a background noise in knock-free operation, for example. The error detection or diagnosis process is only carried out for the cylinder emitting or registering the loudest noise, respectively.

    Abstract: The invention relates to a method and to a device for controlling the idle operation of a drive unit. According to the inventive method, a control unit influences the advance angle of an internal combustion engine on the basis of a deviation between an actual and a desired variable. Said control unit is characterized by at least one modifiable parameter which in operative phases in which an adjustment of the advance angle to early is not desired takes a value different from the normal operation that limits the effect of the advance angle intervention.

    Abstract: The invention relates to a method of adapting the ignition timing in an internal combustion engine to the crankshaft position depending on variations in engine r.p.m., load and overlap between the inlet and exhaust valves. The ratio between combusted and non-combusted gas in the cylinders is computed, and this ratio is utilized, in such a way that the greater the proportion of combusted gas there is, the earlier the ignition will be initiated. The invention also relates to an engine with a control unit (9) and means (11, 13, 14, 15) for computing said ratio, and controlling the ignition timing in the disclosed manner.

    Abstract: The total ignition angle ZW(z) of each cylinder z is composed of cylinder-selective values basic ignition angle GZ(z) [determined by engine speed n and load L], knock adjustment angle KNK(z), in addition to a first adaptation value AD1(z) and a second adaptation value AD2 common to all cylinders. AD1(z) is increased when KNK(z) is greater than a theshold DEC and is reduced when KNK(z) is lower than a threshold INC. AD2 is formed as a function of the average value AD1 of the adaptation values of all cylinders.
