    • A device for increasing an amount of fuel to be supplied to an engine includes a fuel increasing mechanism for supplying an added amount of fuel to the engine, and an electric control circuit including a low-temperature sensor for detecting a low temperature of the engine to produce a first signal capable of actuating the fuel increasing mechanism, and a neutral-gear-condition detector for detecting the neutral-gear-condition of a gear transmission associated with the engine to produce a second signal. The fuel increasing mechanism is inactivated in response to the second signal from the neutral-gear-condition sensor by overriding the low-temperature sensor to prevent the increase of fuel while the gear transmission is in neutral. A second embodiment employs additional sensors for air temperature, engine r.p.m., vehicle speed and the park-condition of an automatic transmission also for controlling the fuel increase.
    • 用于增加供给发动机的燃料量的装置包括用于向发动机供给附加量的燃料的燃料增加机构,以及包括用于检测发动机的低温的低温传感器的电气控制电路 产生能够致动燃料增加机构的第一信号,以及用于检测与发动机相关联的齿轮传动装置的空档状态以产生第二信号的空档状态检测器。 通过覆盖低温传感器来响应于来自中性齿轮传动状态传感器的第二信号而使燃料增加机构失活,以防止在齿轮传动处于空档状态时燃料的增加。 第二实施例使用用于空气温度,发动机转速,车速和用于控制燃料增加的自动变速器的驻车状态的附加传感器。

    • An idling speed control system for controlling idling rotational speed of an internal combustion engine. A vacuum-operated actuator having a diaphragm defining a vacuum chamber controls opening and closing of a throttle valve in response to first and second control pressures supplied from a change-over control valve to the vacuum chamber. An electronic control unit generates, in response to an on-off control pulse signal having a period corresponding to rotational speed of the engine, one of on-period and off-period of the on-off control pulse signal having a predetermined constant value, and supplies the change-over control valve with the control pulse signal. Preferably, a detector is connected to the electronic control unit for detecting a change in the magnitude of a load on the engine and supplying the electronic control unit with an output signal indicative of the detected change in the load magnitude. The electronic control unit is responsive to the output signal for setting the pulse duration of the on-off control pulse signal to a value different from the above predetermined constant pulse duration. A delay valve provided across a passage connecting between the vacuum chamber and the change-over control valve sets the feeding speed of the first control pressure and that of the second control pressure fed through the passage to different values from each other.
    • 一种用于控制内燃机的空转转速的怠速控制系统。 具有限定真空室的隔膜的真空操作致动器响应于从转换控制阀提供给真空室的第一和第二控制压力来控制节流阀的打开和关闭。 电子控制单元响应于具有对应于发动机的转速的周期的开 - 关控制脉冲信号,产生具有预定常数值的开 - 关控制脉冲信号的导通周期和非周期中的一个, 并向转换控制阀提供控制脉冲信号。 优选地,检测器连接到电子控制单元,用于检测发动机上的负载的大小的变化,并向电子控制单元提供指示检测到的负载大小变化的输出信号。 电子控制单元响应输出信号,将开关控制脉冲信号的脉冲持续时间设定为与上述预定恒定脉冲持续时间不同的值。 设置在连接真空室和转换控制阀之间的通道的延迟阀将第一控制压力的进给速度和通过通道供给的第二控制压力的进给速度设定为彼此不同的值。

    • Apparatus for preventing undesirable reduction in the speed of an engine after starting and including an actuator operable upon engine starting to correct throttle opening to a determined extent in increasing direction, a vacuum power system for the actuator and a switching control circuit for detecting engine starting and predetermined running states of the vehicle and engine to keep the actuator energized as long as the engine speed and the vehicle speed are both below respective preset level. Even after the preset level of vehicle speed has been exceeded, the actuator is also energized in the presence of battery load, such as air conditioning or headlights when the engine speed remains below its preset level. The actuator is de-energized when the vehicle speed exceeds its preset level in the absence of battery load as well as when the preset level of engine speed is exceeded.
    • 用于防止在启动后发动机速度不希望降低的装置,并且包括在发动机起动时可操作的致动器,以在增加的方向上确定的程度校正节气门开度;用于致动器的真空动力系统和用于检测发动机起动的开关控制电路, 只要发动机转速和车速低于相应的预设水平,车辆和发动机的预定行驶状态就保持致动器通电。 即使已经超过预设的车速水平,当发动机转速保持低于预设水平时,执行机构也会在存在电池负载(如空调或前大灯)的情况下通电。 当没有电池负载以及超过预设的发动机转速水平时,当车速超过其预设值时,执行机构断电。
