    • A control system for the ignition system of an internal combustion engine for providing faster idle speed when the engine is at a low temperature by advancing the spark timing. A first temperature sensor which senses actual temperature is mounted in the engine ignition control circuit which is, in turn, mounted in proximity to the engine so as to approximate its temperature. A on/off temperature switch is mounted directly in the engine so as to sense when engine temperature is above a predetermined value. The system is operative to provide ignition control by the actual engine temperature unless the second on/off switch is turned on to indicate that the engine temperature has not returned ambient temperature after a running period. If the engine temperature switch is on, normal ignition timing is employed.
    • 一种用于内燃机点火系统的控制系统,用于通过提前火花正时在发动机处于低温时提供更快的怠速。 感测实际温度的第一温度传感器安装在发动机点火控制电路中,发动机点火控制电路依次安装在发动机附近以接近其温度。 开/关温度开关直接安装在发动机中,以便在发动机温度高于预定值时感测。 该系统可操作以通过实际的发动机温度提供点火控制,除非开启第二个开/关开关,以指示发动机温度在运行期后没有返回环境温度。 如果发动机温度开关打开,则采用正常点火正时。
