    • PURPOSE: To prevent engine oil from being unnecessarily exchanged and used with its excessive deterioration by providing a computing means to send out an output signal when the integrated value of the coefficient of deterioration for every deterioration factor of engine oil exceeds a set standard value.
      CONSTITUTION: A load sensor 2, a revolution sensor 3 and a temperature sensor 4 detect a physical amount closely related with the degree of deterioration of engine oil. A microcomputer 6 finds out the coefficient of deterioration for every deterioration factor of the engine oil to add up it together, and integrates each added up value with passage of time. When the above integrated value speeds even one set standard value for every deterioration factor, the microcomputer 6 sends out an output signal. An alarm lamp 8 lights op on receiving the output signal from the microcomputer 6 to warn of the time of exchanging the engine oil.

    • 目的:为了防止发动机油因发动机油的每个劣化因子的劣化系数的积分值超过设定的标准值,通过提供计算装置输出输出信号,防止发动机油被不必要地更换和使用过度劣化。 构成:载荷传感器2,旋转传感器3和温度传感器4检测与发动机油的劣化程度密切相关的物理量。 微机6发现发动机油的每个劣化因子的劣化系数相加在一起,并将每个相加值与时间的流逝相结合。 当上述积分值对每个劣化因子均匀地设定一个标准值时,微计算机6发出输出信号。 报警灯8接收到来自微型计算机6的输出信号发光,警告发动机机油的更换时间。
