    • A system for controlling the amount of air taken in by an engine comprises an air duct tube bypassing a throttle valve of an intake tube for taking in air supplied to an automobile engine, a plurality of valves for regulating the amount of air passing through the air duct tube, and control device therefor. The amount of air in the bypass is controlled in accordance with the temperature and number of revolutions of the engine and the air intake pressure downstream of the throttle valve. During the idling of the engine, the air intake control system generates a signal representing the standard engine idling revolutions in accordance with the engine temperature, compares the actual engine revolutions with a reference, and regulates the amount of air flowing in the bypass by use of the results of a comparison, thus rendering the actual engine revolutions identical to the reference. During the loaded engine operation, by contrast, the amount of bypass air is so controlled that the air intake pressure downstream of the throttle valve is maintained at predetermined constant value.
    • 用于控制由发动机吸入的空气量的系统包括绕过用于吸入供应到汽车发动机的空气的进气管的节流阀的空气管道管,用于调节通过空气的空气量的多个阀 管道管及其控制装置。 旁路中的空气量根据发动机的转速和节气门下游的进气压力进行控制。 在发动机怠速期间,进气控制系统根据发动机温度产生表示标准发动机怠速转数的信号,将实际发动机转数与参考值进行比较,并且通过使用发动机温度调节在旁路中流动的空气量 比较结果,从而使实际的发动机转数与参考相同。 相反,在负载发动机运转期间,旁路空气的量受到控制,使得节流阀下游的进气压力保持在预定的恒定值。

    • The combination of a fuel supply system for an internal combustion engine, an exhaust gas oxygen concentration sensor and a feedback control system including an integration circuit connected to the fuel supply system and a correction control circuit connected to the exhaust gas oxygen concentration sensor and the integration circuit. The combination controls the air-fuel mixture to be supplied to an engine in accordance with an integration output signal, which in turn is generated from the output signal generated by the exhaust gas oxygen concentration sensor. The correction control circuit serves to disconnect the exhaust gas oxygen concentration sensor from the integration circuit when a predetermined operating condition of the engine is reached, thereby holding the output from the integration circuit constant.
    • 用于内燃机的燃料供应系统,废气氧浓度传感器和包括连接到燃料供应系统的积分电路的反馈控制系统和连接到排气氧浓度传感器的校正控制电路和积分 电路。 该组合根据积分输出信号控制供应给发动机的空气 - 燃料混合物,积分输出信号又由废气氧浓度传感器产生的输出信号产生。 校正控制电路用于在达到发动机的预定运行状态时将排气氧浓度传感器与积分电路断开,从而使积分电路的输出保持恒定。
