摘要： A method of controlling ignition timing of an internal combustion engine when an abnormality develops in a system for sensing a reference crank angle position of a crankshaft of the engine, in which the timing at which an ignition coil starts and stops conducting is controlled on the basis of a first pulse signal generated once per at least two revolutions of the crankshaft at a predetermined crank angle position associated with a particular cylinder of the engine, a second pulse signal indicative of a predetermined reference crank angle position of the crankshaft for each cylinder, and a third pulse signal indicative of a predetermined angular position of the crankshaft. The method comprises the steps of sensing an abnormality in the reference crank angle position sensing system for sensing the predetermined reference crank angle position, generating a pseudo-signal pulse having a predetermined pulse width in place of the second pulse signal on the basis of the first and third pulse signals when the second pulse signal fails to be generated because of the abnormality in the reference crank angle position sensing system, starting conduction of the ignition coil at a leading edge of the pseudo-signal pulse, and stopping conduction of the ignition coil at a trailing edge of the pseudo-signal pulse.

摘要： An ignition timing control method for an internal combustion engine in which an ignition advance angle value conforming to the operating condition of the engine is set, an ignition timing is obtained by applying an angle-time conversion to a crank angle extending from a reference crank angle position to a position corresponding to the ignition advance angle value, and ignition is effected upon lapse of the ignition timing from an instant at which the reference crank angle position is sensed. Engine rotational speed value is sensed at least at two particular crank angle positions, and each sensed rotational speed is stored in memory. A ratio between the at least two rotational speed values stored in an immediately preceding ignition cycle is calculated, and the ignition timing of a present ignition cycle is corrected by using the calculated ratio.

摘要： A test system for simultaneously testing a plurality of logic circuits first sets them all to an initial state before beginning testing. The faulty logic circuits which cannot be set to the initial state can be identified, and the testing of the others can proceed, even after only one cycle of attempting to initialize all the logic circuits. If all the logic circuits are faulty, the further testing can be prevented.

摘要： An ignition timing control method for an internal combustion engine, which controls the ignition timing of a mixture to be supplied to the engine in a feedback manner responsive to the difference between the actual engine speed and the desired idling speed. When it is determined that the engine is in a predetermined idling region and the engine temperature is above a predetermined value, the ignition timing is retarded by a predetermined amount, and the ignition timing thus retarded is corrected by a correction value calculated by multiplying the difference between the actual engine speed and the desired idling speed by a predetermined coefficient, to thereby control the ignition timing to the ignition timing value thus corrected. The ignition timing feedback control is inhibited when the voltage at a predetermined input terminal of a central processing unit is at a predetermined input level.

摘要： A desired value of ignition timing and a correction value therefor are calculated at a timing corresponding to a first specific one of sensed predetermined crank angle positions of each cylinder of the engine. Data indicative of the calculated desired value of ignition timing are set in a counter to start counting based upon the set data at a second specific one of the predetermined crank angle positions, subsequent to the first specific one, so that the ignition takes place upon completion of the counting. When it is determined from the calculated desired value of ignition timing whether the ignition is to be effected after a third specific one of the predetermined crank angle positions, subsequent to the second specific one, the data set in the counter is updated to the calculated correction value, at the third specific one of the predetermined crank angle positions.

摘要： An ignition timing control method for an internal combustion engine wherein a plurality of correction values for ignition timing are stored in memory means beforehand as a function of an output voltage from a variable voltage creating means which is humanly adjustable and the rotational speed of the engine. The output voltage from the variable voltage creating means and the rotational speed of the engine are detected, and one of the correction values is read, which corresponds to the detected output voltage and the detected rotational speed of the engine. Then, the ignition timing is corrected by the use of the read one correction value. Further, a value of a parameter indicative of load on the engine is detected, and the ignition timing control is executed when the detected value of the parameter is above a predetermined value. Alternatively, in place of the correction values, address values are stored in memory means. One of the address values is read, which corresponds to the detected output voltage and converted to a numerical value in the number system with a predetermined number as the base. The figures of the numerical value correspond to respective regions of the engine rotational speed. A correction value for correcting the ignition timing is determined in accordance with one of the figures of the numerical value corresponding to the region of the engine rotational speed in which the engine is detected to be operating.
