    • An engine rotational speed display device includes a rotational speed sensor and a pulse rotor. An engine rotational speed calculating unit is configured to calculate an engine rotational speed by a moving average of a detected value of a crankshaft rotational speed pulse. A display unit is configured to display the engine rotational speed on a meter by electrical processing. When the crankshaft rotational speed pulse is not detected in a detection time equal to or more than a predetermined value, the engine rotational speed calculating unit determines that the engine rotational speed is “0,” and the engine rotational speed of “0” is displayed on the meter.
    • 发动机转速显示装置包括转速传感器和脉冲转子。 发动机转速计算单元,用于通过曲轴转速脉冲的检测值的移动平均值来计算发动机转速。 显示单元被配置为通过电处理在仪表上显示发动机转速。 当在等于或大于预定值的检测时间内未检测到曲轴转速脉冲时,发动机转速计算单元确定发动机转速为“0”,并显示发动机转速“0” 在仪表上
