摘要： To effect EGR in an internal combustion engine with the maintenance of adequate balance between the suppression of NO.sub.x formation and preservation of stable engine operation, the condition of combustion in the engine is taken as the basis of feedback control of the volume of recirculated exhaust gas so as to correct a deviation of the total amount of the recirculated exhaust gas and unexhausted combustion gas in the combustion chamber from a desired amount. The intensity of an ionic current produced upon combustion in each combustion chamber, the magnitude of mechanical vibration of the engine or the frequency of misfire in a combustion chamber is detected as an exact indication of the condition of combustion.

摘要： In a PWM control type power supply apparatus, a modulation (high frequency) signal component is eliminated from an AC output. The PWM control type power supply apparatus includes: AC-to-DC converting means coupled to an AC (alternating current) power source capable of supplying a first AC voltage having a low frequency from a pair of output terminals, for converting the first AC voltage to obtain a positive DC (direct current) voltage from a positive half cycle of the first AC voltage appearing at one output terminal and a negative DC voltage from a negative half cycle of the first AC voltage appearing at one output terminal with a common voltage appearing at the other output terminal; and, DC-to-AC inverter means including a pair of first and second switching elements, and a PWM (pulse width modulation) controller for controlling switching operations of the first and second switching elements in a PWM control mode so as to invert the positive and negative DC voltage into a second AC voltage having a modulation frequency higher than the low frequency with respect to the common voltage output terminal, whereby the second AC voltage contains no modulation frequency component.

摘要： This detective circuit detects an abnormal drop of an input voltage of a switching regulator of the flyback system. From the secondary winding of the switching regulator, a constant voltage controlled dc voltage is delivered through a diode. This circuit is provided with a peak voltage charging circuit which detects the peak value of a voltage produced in a direction opposite to the forward direction of the diode, and a voltage comparator which compares the peak value with a setting value. Since this peak value is in proportion to the input voltage, the output of the voltage comparator indicates an abnormal drop of the input voltage.

摘要： In a spark-ignited internal combustion engine having a plurality of combustion chambers, at least one combustion chamber is intentionally caused to misfire either periodically or continuously to increase the amount of unburned fuel in the exhaust gas when the temperature in the thermal reactor drops excessively during, e.g., idling of the engine. An ignition system for performing the method has a supplementary ignition primary circuit which is normally disconnected from the ignition coil primary, but causes the secondary voltage either to become zero periodically or to lower when connected with the ignition coil primary. Alternatively, the ignition timing is retarded from a normal timing in a portion of the combustion chambers to raise the exhaust gas temperature. An ignition system for the ignition timing retardation has a supplementary circuit which prevents certain times of the breaks in the primary circuit from producing sparks in the intended combustion chambers and supplies a high voltage pulse to each of these combustion chambers with a predetermined time delay from each of the breaks which are made ineffectual.
摘要翻译：在具有多个燃烧室的火花点燃内燃机中，当热反应堆中的温度过度下降时，至少一个燃烧室有意地周期性地或连续地失火以增加废气中的未燃烧燃料的量，，例如发动机空转。用于执行该方法的点火系统具有通常与点火线圈一次断开的补充点火一次回路，但是当与点火线圈原件连接时，二次电压也会周期性变为零或降低。或者，点燃正时从燃烧室的一部分的正常时刻延迟，以提高废气温度。用于点火正时延迟的点火系统具有辅助电路，其防止初级回路中的某些时间断裂在预期燃烧室中产生火花，并且以每个这些燃烧室的预定时间延迟从这些燃烧室提供高电压脉冲的休息是无效的。
