    • The present invention relates to an apparatus (1) for deciding engine-oil replacing time for an automobile. The apparatus comprises a pulse input unit (3) into which is inputted a pulse generated during the rotation of the engine of an automobile to calculate rotational frequency of the engine on the basis of the pulse, a rotational-frequency integration unit (4) for receiving a signal of rotational frequency of the engine outputted from the pulse input unit (3) to integrate the rotational frequency of the engine, and a display unit (5) into which is inputted an integrated value from the rotational-frequency integration unit (4) and in which a degree of oil degradation on the basis of the integrated value is displayed by a display (12) such as a LED, a liquid crystal, a 7-segment or the like.
    • 本发明涉及一种用于决定汽车的机油换油时间的装置(1)。 该装置包括:脉冲输入单元(3),其输入在汽车的发动机旋转期间产生的脉冲,以基于脉冲计算发动机的转速;旋转频率积分单元(4),用于 接收从脉冲输入部(3)输出的发动机的转速信号,使发动机的转速结合起来;以及显示部(5),其从旋转频率积分部(4)输入积分值 ),并且其中通过诸如LED,液晶,7段等的显示器(12)显示基于积分值的油劣化程度。
