    摘要： An ignition timing control system for an engine provides a counter-measure for an abnormal condition of a signal. The ignition timing control system has a first signal generator for generating a first signal at intervals of a predetermined crank angle while an engine is rotated n times (n is an arbitrary positive number), this first signal including a marked signal designating a particular cylinder each time the engine is rotated n times; a second signal generator for generating a second signal having pulses in a number equal to that of all cylinders of the engine at intervals of substantially an equal crank angle in synchronism with the first signal, this second signal including a signal of a form which is distinguishable from other second signal and which occurs in synchronism with the marked signal; a unit for producing an ignition signal in response to the first signal; a distributor for receiving the ignition signal and distributing the ignition signal in response to the marked signal of the first signal to each cylinder in a predetermined ignition order; a unit for detecting an abnormal condition of the first signal; and a unit for distributing the ignition signal to each cylinder in a predetermined ignition order in response to the signal synchronized with the marked signal of the second signal in place of the marked signal when the abnormal condition of the first signal is detected.

    摘要： The present invention relates to an engine control device adapted to determine a basic fuel feed rate (Tp) in response to signals from a suction air flow rate sensor (20) and an air-fuel ratio sensor (20), and thereafter a fuel feed rate (Ti). According to the present invention, suction air flow rates (Q.sub.An-1, Q.sub.An-2) are calculated first on the basis of the last and the next to last fuel feed rates (Tin-1, Tin-2). The coefficients (A, B) required to correct the properties of the suction air flow rate sensor (20) are computed on the basis of these suction air flow rates. In the present invention, a fuel feed rate is determined finally on the basis of these coefficients.

    摘要： A main computer which furnishes main engine control signals to initiate a predetermined operation of an internal combustion engine, outputs a monitoring signal whose state changes between a high and a low levels at predetermined intervals. The monitoring signal is watched by a main computer monitor, which maintains its output at a high level during repetition of the change of state in the monitoring signal and, in absence of the change of state in the monitoring signal, changes the state of its output between the high and a low levels at intervals longer than that of the monitoring signal. A backup computer which furnishes auxiliary engine control signals to initiate the minimum operational condition of the engine, monitors the output of the main computer monitor to detect a malfunction or abnormal operation of the main computer. When the number of the changes of state in the output of the main computer monitor exceeds a predetermined value, the malfunction of the main computer is judged to be serious so that the backup computer provides a switching request signal. Under the condition of existence of the switching request signal and that the backup computer is properly operating, switching from the main to the backup computer takes place.

    摘要： Disclosed is an electronic ignition signal distributor for automobile engine, in which cylinders of the engine are identified using an ignition sequence counter and basing on the reference position signal and crank angle signal. The cylinder identity signal is taken AND with the distributed ignition position signal before being applied to the ignition device, thereby preventing the delivery of an active ignition signal in the event of a malfunctioning of the counter or cylinder identifying circuit, and ultimately preventing an erroneous ignition of irrelevant cylinders caused by a noise or the like.

    摘要： In order to ensures a stable reduction of noise level at all times, in the steps of switching input voltage with a switching element 10, smoothing the voltage of rectangular wave obtained by switching with a reactor L and capacitor Cf and outputting it, the voltage obtained by dividing the output voltage is compared with the sawtooth wave output from a sawtooth wave generator 14 by a comparator 12. When the switching signal in response to the result of this comparison is applied to the switching element 10, the counter 16 is actuated synchronously with the vertex of the sawtooth wave to perform opening/closing operation of the switch SW1. The time constant of the time constant circuit comprising a R0 and C is adjusted according to whether a resistor R1 is present or not, and the signals of frequencies f1 and f2 coming out of the sawtooth wave generator 14 are sequentially switched to be sent to the comparator 12. The peak of the switching noise is diffused in the frequency range by sequential selection of switching frequencies, and noise level is reduced by diffusion of noise energy.
