Abstract: An ignition timing control method for an internal combustion engine having a catalytic exhaust emission purifier for scrubbing toxic exhaust gas components from engine exhaust gases by means of a catalyst, wherein the timing at which a mixture in the engine is ignited is controlled on the basis of an ignition timing set in dependence upon operating parameters of the engine. The method comprises the steps of sensing temperature of the engine after the engine is started, sensing elapsed time from the moment the engine is started when the sensed temperature lies within a predetermined temperature range, setting a delay angle correction amount in dependence upon the sensed elapsed time, correcting the ignition timing by the set delay angle correction amount, and controlling the ignition timing in accordance with the ignition timing so corrected. Preferably, the correction of the ignition timing is effected only when a particular operating condition of the engine is sensed.

Abstract: A knock control system for an internal combustion engine has a knock discrimination level. If an output signal from a knock sensor is higher than the knock discrimination level, then the knock control system determines that the engine is subjected to knock and retards the ignition timing. If the knock sensor output signal is lower than the knock discrimination level, i.e., if no knock or detonation is detected over a prescribed period of time, then the ignition timing is advanced. At least two corrective levels are established for comparison with a knock discrimination level, and occurrences in which the maximum value of the output signal from the knock sensor exceeds the corrective levels. The knock discrimination level is automatically corrected dependent on the counts of such occurrences.

Abstract: A system and method for controlling an ignition timing of an internal combustion engine. In the system, an accumulated value of a deviation or a value corelative to the accumulated value is calculated as an error amount whenever the deviation between a crank angle value at a time when pressure in a combustion chamber has reached its maximum and a target value thereof, whether the error amount exceeds a predetermined allowable limit value is determined whether the error amount is calculated, a corrective amount of ignition timing is calculated when the error amount exceeds the predetermined allowable limit value. Consequently, the correction of ignition timing can be carried out in a quick response during the ransient driving state of engine and engine drivability can be improved.

Abstract: An ignition system for providing individual cylinder spark control includes a shaft encoder driven by the engine crankshaft which provides a primary timing pulse at the top dead center point of cylinder No. 1 as well as a large number of encoder pulses per engine revolution. With the primary timing pulse as a reference, the encoder pulses are supplied to a modulo N counter which provides output pulses at the theoretical top dead center point of each cylinder, to a cylinder address counter and to a fixed delay counter, which provides an output a fixed number of encoder pulses from the previous output pulse from the modulo N counter to set a maximum ignition advance point. A memory device has a channel programmed with information as to the variation, in terms of encoder pulses (crank angle) of each cylinder actual top dead center from the theoretical angle as defined by the modulo N counter output. The memory receives cylinder address information and the output from the fixed delay counter to cause it to unload binary information defining the delay from the maximum advance point to the variable delay counter. The variable delay counter output then sets the ignition timing for each individual cylinder.

Abstract: A control method and apparatus for combating knocking in internal combustion engines which automatically adapts itself to the internal combustion engine to be controlled and, as a result of the automatic adaptation, is capable of employment, without adjustments, on different model-lines and on the individual examples of the internal combustion engines, within these lines and falling within the permissible scatter-range. Anti-knock control is obtained by means of a technique whereby the control input signal (for example, to retard the ignition timing) is increased while knock-signals are occurring, and is reduced if knock-signals do not occur, whereby, following the occurrence of knock-signals, the threshold value for detection of knock-signals is increased, as long as either the knock-signals do not diminish, in spite of the control input signal having been increased, or whereby, if a defined period has elapsed since the last reduction of the control input signal, and knock-signals are not occurring, the threshold value is reduced, or held constant.
