    • When the value of a power supply voltage (VDD) becomes a first threshold value or higher, a first start-up circuit (20) causes a band gap reference circuit (10) to start a stable operation and a first voltage value (VA) is output from the band gap reference circuit (10). When the value of the power supply voltage becomes a second threshold value or higher which is greater than the first threshold, a second start-up circuit (40) turns on a PMOS transistor (MP3) of a voltage dividing circuit (30), and a second voltage value (VB) output from the voltage dividing circuit (30) becomes a value, which is derived by dividing the value of the power supply voltage according to the resistance ratio of resistors (R31, R32). From a voltage comparison circuit (50), a reset level voltage value is output when the second voltage value (VB) is smaller than the first voltage value (VA), and a power-supply voltage level voltage value is output if the second voltage value (VB) becomes the first voltage value (VA) or higher.
    • 当电源电压(VDD)的值成为第一阈值以上时,第一启动电路(20)使带隙基准电路(10)开始稳定动作,第一电压值(VA) 从带隙参考电路(10)输出。 当电源电压值变得大于第一阈值的第二阈值以上时,第二启动电路(40)导通分压电路(30)的PMOS晶体管(MP3),并且 从分压电路(30)输出的第二电压值(VB)成为通过根据电阻器(R31,R32)的电阻比除以电源电压值而导出的值。 从电压比较电路(50),当第二电压值(VB)小于第一电压值(VA)时,输出复位电平电压值,如果第二电压值 值(VB)成为第一电压值(VA)以上。

    • Provided are a method of operating an engine and an apparatus for controlling operation of an engine, which is capable of appropriately controlling the operation of the engine after cutoff of fuel into a cylinder in which heavy knock occurs, without at once stopping the engine upon detection of occurrence of the heavy knock. The method of operating an engine which has a plurality of cylinders, and which is capable of stepwise or continuously correcting a burning state through fuel regulation including cutoff of fuel, upon occurrence of abnormal combustion, executes a stop or an output limit operation of the engine, and is characterized in that a simulated abnormal combustion obtained by calculating an abnormal combustion state of the engine in simulation is beforehand set, and in comparison of a detection signal as to a burning state of a selected cylinder which is sequentially selected among the plurality of cylinders, with the simulated abnormal combustion signal so as to determine occurrence of abnormal combustion in the selected cylinder in order to execute cutoff of fuel into the selected cylinder.
