摘要： In an electronic governor for an internal combustion engine provided with a fuel injection pump having a control rack for adjusting fuel supply, a constant speed control signal Vnd for control to maintain the deviation of the actual speed N from a designated speed No within a permissible range, and a maximum rack position control signal VLd for control to maintain the deviation of the rack position from the maximum position for the particular speed N within a permissible range, are inputted into a control mode selector, which outputs the constant speed control signal Vnd when a speed detection signal Vn is not smaller than a designated speed signal Vno, or when the speed detection signal Vn is smaller than the designated speed signal Vno and the rack is below the maximum position, and outputs the maximum rack position control signal VLd when the speed detection signal Vn is smaller than the designated speed signal Vno and rack is above the maximum position. The output of the control mode selector is used to control the rack to cause the deviation of the actual speed N from the designated speed No or the rack position from the maximum position to be within a certain range.

摘要： In an electronic governor for an internal combustion engine provided with a fuel injection pump having a control rack for adjusting fuel supply, an accelerator position signal Vs and a speed detection signal Vn are inputted into a speed deviation operation circuit for producing a speed deviation signal, which is integrated by an intergrator. The integral signal from the integrator is used for controlling the rack. The integral signal is also inputted into a droop operation circuit producing a droop factor signal Va whose magnitude is proportional to the intergral signal. The speed deviation operation circuit produces, as the speed deviation signal, a signal corresponding to Vn-(Vs+Va) or Vn-(Vs-Va).

摘要： Disclosed herein is an ignition system for an internal combustion engine including a capacitor charged by charge power source, a thyristor for discharging the capacitor through the primary of an ignition coil and a magneto AC generator including a signal generating winding for supplying a gate signal to the thyristor. The ignition system is characterized in that rate of change of the magnetic flux interlinked with the signal generating winding has at least two successive local maximum points, so that at least two successive peaks of the same polarity appears in the voltage induced in the signal generating winding by the magnetic flux variation. The waveform of the voltage induced is utilized for ignition angle advance.

摘要： This invention relates to an ignition system for an internal combustion engine in which an advance characteristic is provided by utilizing a discharge of a capacitor. The ignition system comprises an ignition coil, a semiconductor switch to control a primary current through the ignition coil, a signal coil to generate a signal of one cycle per one revolution of the internal combustion engine, an ignition position control circuit to produce a conducting signal for conducting the semiconductor switch with the signal from the signal coil used as a control signal. The ignition coil is operated by rapidly varying the primary current through the ignition coil by means of the conduction of the semiconductor switch.The ignition position control circuit includes capacitor means, a capacitor charging circuit to charge the capacitor means with one polarity by a constant current flowing from a DC power source through a unilateral element such as a diode or a transistor, a capacitor discharging circuit having a discharge control switch conducting during leading one half cycle of a signal from the signal coil to discharge the capacitor means through the discharge control switch. The ignition control circuit further includes a reference voltage generating circuit to generate a reference voltage of a value lower than the maximum value of the voltage across the capacitor means and a conducting signal generating circuit to generate a conducting signal when the voltage across the capacitor means becomes lower than the reference voltage.
