摘要： PURPOSE:To prompt the timing of starting the use of an oxygen sensor with an accurate and quick discrimination of active state, by feeding a discrimination voltage alone until active state is discriminated while the supply of a sensor driving voltage is stopped. CONSTITUTION:When power is supplied to a constant voltage circuit 5 and a control unit 9 with the starting of an engine, a discrimination voltage Vz is fed to an oxygen sensor 1 from a discrimination voltage supply means 6. The sensor output Es varies only with changes in the resistance value r3 of a thermistor 3, namely, the sensor temperature T alone thereby enabling accurate discrimination of active state without being affected by the concentration oxygen. When judging that the oxygen sensor 1 is active, a discrimination means 21 outputs a switching signal Sz to have a reference voltage supply means 22 supplying a sensor driving voltage V1 to the oxygen sensor 1 closing the contact of a relay 23. The sensor output Es is inputted into an oxygen concentration detecting means 24 and a rich/lean signal R/L is outputted into a control unit 9.
摘要翻译：目的：通过准确，快速地识别有源状态来提示开始使用氧传感器的时间，通过单独馈送鉴别电压直到当传感器驱动电压的供应停止时识别为有效状态为止。构成：当通过发动机起动向恒压电路5和控制单元9供电时，判别电压Vz从识别电压供给装置6供给到氧传感器1.传感器输出Es仅根据热敏电阻3的电阻值r3的变化，即传感器温度T单独，从而能够精确地区分活性状态而不受浓度氧的影响。当判断为氧传感器1有效时，鉴别装置21将切换信号Sz输出给具有传感器驱动电压V1的基准电压供给装置22，该氧传感器1关闭继电器23的触点。传感器输出Es 被输入到氧浓度检测装置24中，并且浓/稀信号R / L被输出到控制单元9中。

摘要： PURPOSE:To achieve proper air-fuel ratio by executing the weighting operation if an external load is coupled when transferring to the decelerating condition. CONSTITUTION:Correction signal producing means (e) will produce correction signals untill deceleration is stopped if an external load is coupled when the engine has transferred to specific decelerating condition. Upon provision of correction signal, output correction means (f) will correct the output from intake condition detecting means (a) to correspond with current condition of intake air on the basis of the intake air condition predetermined time before. Consequently, proper air-fuel ratio of mixture gas can be achieved.
摘要翻译：目的：通过执行加速操作来实现适当的空燃比，如果在转向减速状态时外部负载耦合。构成：修正信号产生装置（e）将产生校正信号，直到当发动机转移到特定的减速条件时外部负载被耦合时，减速停止。在提供校正信号时，输出校正装置（f）将根据预先确定的时间之前的进气条件将进气条件检测装置（a）的输出校正为与进气的当前状态相对应。因此，可以实现混合气体的合适的空燃比。
