    • An engine compartment cooling fan provided in an engine compartment is controlled by a control unit, to be placed in its ON or OFF state, on the basis of an output from an engine compartment temperature sensor. The control unit continues the control of the engine compartment fan for a predetermined period of time after a key switch is turned off, with power supplied from a battery through a by-pass line. This permits the engine to be re-started without difficulty even after a short time of stop of the vehicle. Upon lapse of the predetermined time, the control unit disconnects the power supply through the by-pass line and stops its operation. Since there is no power consumption after the end of the operation of the cooling fan, unnecessary consumption of the battery can be avoided.
    • 发动机舱冷却风扇设置在发动机舱中,由控制单元控制,根据发动机舱温度传感器的输出,将其置于ON或OFF状态。 控制单元通过旁路线从电池供电,在钥匙开关关闭之后,继续对发动机舱风扇的控制一段预定的时间。 即使在车辆的停止时间短的情况下,也能够使发动机重新起动。 在经过预定时间后,控制单元通过旁路线断开电源并停止其操作。 由于在冷却风扇的运行结束后没有功率消耗,因此可以避免电池的不必要的消耗。
