    • PROBLEM TO BE SOLVED: To inhibit the degradation of a battery during the dead soak of an engine and improve restartability at high temperatures and idle rotation stability by efficiently cooling the engine.SOLUTION: A cooling device cools an engine body 2 by circulating cooling water between an engine body 2 and a radiator 3 using an electric motor 1 and by supplying cooling wind to the radiator 3 using an electric fan 4. A control unit 30 controls the operational states of the electric motor 1 and the electric fan 4 based on a cooling water temperature THW detected by a water temperature sensor 21, an outdoor air temperature THA detected by an outdoor air temperature sensor 22 and a battery voltage GBA during the dead soak after the engine is stopped. Specifically, the control unit 30 controls the electric motor 1 and the electric fan 4 when determining that the engine is at a high temperature based on the cooling water temperature THW and the outdoor air temperature THA at the stop of the engine.
    • 要解决的问题:通过有效地冷却发动机来抑制发动机死水时电池的劣化,提高高温下的再启动能力和怠速转动的稳定性。 解决方案:冷却装置通过使用电动机1在发动机主体2和散热器3之间循环冷却水并且使用电风扇4向散热器3供给冷却风来冷却发动机主体2.控制单元30 基于由水温传感器21检测到的冷却水温度THW,室外空气温度传感器22检测到的室外温度THA和死亡时的电池电压GBA来控制电动机1和电动风扇4的运转状态 发动机停止后浸泡。 具体地说,控制单元30基于发动机停止时的冷却水温度THW和室外空气温度THA来判定发动机处于高温时,控制电动机1和电动风扇4。 版权所有(C)2012,JPO&INPIT

    • PROBLEM TO BE SOLVED: To prevent occurrence of cavitation which may occur in a cooling water pump 1, when a fuel cell is restarted immediately after being stopped, in a vehicle traveling with the energy of the fuel cell 2 serving as a drive energy generation device.SOLUTION: There is provided a fuel cell 2 for generating energy used to cause a vehicle to travel. A reserve tank inlet valve 10 is arranged in a position slightly nearer to an intake side of a cooling water pump 1 than a position of a cooling water circuit where pressure of cooling water controlled by the reserve tank inlet valve 10 adopts a middle value between discharge pressure of the cooling water pump 1 during driving and the intake pressure of the cooling water pump 1. Even when the fuel cell 2 stops generating power, when the temperature of the cooling water exceeds a predetermined temperature as in steps S62 and S63, the cooling water pump 1 is kept rotating even while the vehicle is traveling. The rotation of the cooling water pump 1 is stopped after the temperature of the cooling water has fallen at least to the predetermined temperature.
    • 要解决的问题为了防止在冷却水泵1中可能发生的气蚀的发生,当燃料电池在停止后立即重新启动时,在用作驱动能量产生装置的燃料电池2的能量行驶的车辆中 解决方案:提供了用于产生用于使车辆行驶的能量的燃料电池2。 备用油箱入口阀10布置在比冷藏水回路更靠近冷却水泵1的进气侧的位置,其中由储油罐入口阀10控制的冷却水的压力在排出口之间的中间值 驱动时的冷却水泵1的压力和冷却水泵1的吸入压力。即使当燃料电池2停止发电时,如步骤S62,S63所示,当冷却水的温度超过规定温度时, 水泵1即使在车辆行驶时也保持旋转。 在冷却水的温度至少下降到预定温度之后,停止冷却水泵1的旋转。
