    • In a cooling water circuit system, cooling water pumped by a mechanically-driven first water pump circulates in a cooling water circuit, and flows through a radiator and a heater core in parallel in the cooling water circuit. An electrically-driven second water pump is disposed in the cooling water circuit at a position where cooling water to be supplied to the radiator from the first water pump and cooling water to be supplied to the heater core from the first water pump flow together. A check valve is provided in the cooling water circuit in parallel with the second water pump so that cooling water flows in one way from a water suction side of the second water pump toward a discharge side thereof. Thus, when the second water pump is operated, a total amount of cooling water pumped by the first water pump and the second water pump can flow through the radiator and the heater core. As a result, the cooling water circuit system can improve engine-cooling effect in the summer, while improving heating effect of a passenger compartment in the summer.
    • 在冷却水回路系统中,由机械驱动的第一水泵泵送的冷却水在冷却水回路中循环,并且在冷却水回路中流过散热器和加热器芯。 电驱动的第二水泵设置在冷却水回路中,从第一水泵向散热器供给的冷却水和从第一水泵供给到加热器芯的冷却水一起流动。 在与第二水泵并联的冷却水回路中设置止回阀,使得冷却水从第二水泵的吸水侧向排出侧单向流动。 因此,当第二水泵操作时,由第一水泵和第二水泵泵送的冷却水的总量可以流过散热器和加热器芯。 结果,冷却水回路系统可以在夏季提高发动机冷却效果,同时提高夏季乘客车厢的加热效果。

    • A viscous fluid heat generator includes: a shear chamber in which viscous fluid is contained and heat is generated by shearing the viscous fluid with a rotor rotating therein; and a space receiving viscous fluid drained from the shear chamber. The heat generator is rotated always as far as an engine rotates because it is driven by the engine without a clutch. The viscous fluid in the shear chamber is drained into the receiving space disposed underneath the shear chamber when the rotor halts or the heat generator is not in operation. The drained viscous fluid is pushed up again into the shear chamber when the rotor is re-started or the heat generator becomes in operation again. The heat generator is re-started easily with a very small starting torque because there is almost no viscous fluid left in the shear chamber and accordingly power to shear the viscous fluid with the rotor is not required. Only a minimal power is consumed by the heat generator when heat is not required to be generated even though the rotor is continuously rotated because the viscous fluid in the shear chamber is drained in this situation.
    • 粘性流体热发生器包括:剪切室,其中容纳粘性流体并通过在其中旋转的转子剪切粘性流体而产生热量; 以及接收从剪切室排出的粘性流体的空间。 发动机始终旋转直到发动机转动,因为它是由没有离合器的发动机驱动的。 当转子停止或发电机不工作时,剪切室中的粘性流体被排放到设置在剪切室下方的容纳空间中。 当转子重新启动或者发电机再次起作用时,排出的粘性流体再次被推入剪切室。 由于在剪切室中几乎没有粘性流体,所以不需要用转子剪切粘性流体的功率就能以很小的启动扭矩重新启动发热体。 在这种情况下,即使转子连续旋转,因为不需要产生热量,所以只有最小的功率消耗在热量发生器中。

    • A viscous heater for heating cooling water for cooling a water cooled engine is provided in a cooling water circuit between the engine and a front heater core. Even if a viscous switch is turned on by a viscous ECU to heat a passenger compartment using the viscous heater, a viscous clutch is not immediately turned on when the engine is idling. That is, after a delay control time elapses after increasing an idling rotational speed of the engine to a target rotational speed, the viscous heater is turned on. The target rotational speed which is higher than a normal idling rotational speed is set in such a manner that the higher the cooling water temperature is, the lower the target rotational speed becomes. Thus, even if a large load is applied to the engine by operating the viscous heater when the engine is idling, it can improve fuel economy and prevent an engine stall.
    • 用于加热用于冷却水冷发动机的冷却水的粘性加热器设置在发动机和前加热器芯之间的冷却水回路中。 即使粘性开关由粘性ECU接通以使用粘性加热器加热客舱,当发动机空转时,粘性离合器也不会马上开启。 也就是说,在将发动机的空转转速提高到目标转速之后经过延迟控制时间之后,粘性加热器接通。 高于正常怠速转速的目标转速设定为冷却水温度越高,目标转速越低。 因此,即使在发动机怠速时通过操作粘性加热器对发动机施加较大的负荷,也能够提高燃油经济性,防止发动机熄火。
