    • A variable speed fan drive, operated in response to the sensed coolant temperature in an internal combustion engine for a vehicle, blows a controlled amount of air through the engine's radiator to maintain the coolant temperature in a desired narrow operating range. The air pulled in by the fan also cools the refrigerant flowing through the condenser of the vehicle's air conditioning system, the condenser being positioned in front of the coolant radiator. If insufficient condenser cooling occurs, even though the coolant may be adequately cooled, the refrigerant temperature rises and causes the compressor discharge pressure in the air conditioning system to increase. That pressure is monitored or sensed and if it exceeds a predetermined maximum allowable level the normal operation of the control system is overriden and the fan is driven at its maximum speed to maximize the air blown through the condenser and radiator, thereby decreasing the refrigerant temperature and thus the discharge pressure.
    • 响应于用于车辆的内燃机中感测到的冷却剂温度而操作的变速风扇驱动器将受控量的空气吹过发动机的散热器,以将冷却剂温度保持在期望的窄工作范围内。 由风扇牵引的空气还冷却流过车辆空调系统的冷凝器的制冷剂,冷凝器位于冷却剂散热器的前面。 如果发生冷凝器冷却不足,即使冷却剂可以被充分冷却,制冷剂温度升高,并且使空调系统中的压缩机排气压力增加。 该压力被监视或检测,如果超过预定的最大允许水平,则控制系统的正常操作被覆盖并且风扇以其最大速度被驱动以最大化吹过冷凝器和散热器的空气,从而降低制冷剂温度和 从而排出压力。

    • This invention relates to motor vehicles having passenger compartment heating devices. The temperature of the cooling water of an engine may be increased at idling speeds and low speed states by throttling the engine exhaust to increase fuel consumption. A throttle device is controlled in accordance with cooling water temperature and passenger compartment temperature, in response to activation by manual control. Manual control is overridden by an accelerator pedal actuated control when the load of the engine rises. Heat is extracted from the engine cooling water by means of a heat exchanger, through which air is driven into the passenger compartment. A brake is connected to an independently actuated device to throttle the exhaust to brake the engine. This arrangement is particularly suitable for use with diesel engines.
    • 本发明涉及具有客舱加热装置的机动车辆。 发动机的冷却水的温度可以通过节流发动机排气而在怠速和低速状态下增加以增加燃料消耗。 响应于手动控制的激活,节流装置根据冷却水温度和乘客舱室温度进行控制。 当发动机负载升高时,手动控制被加速踏板驱动控制覆盖。 通过热交换器从发动机冷却水中提取热量,通过该热交换器将空气驱动到乘客舱中。 制动器连接到独立致动的装置以节流排气以制动发动机。 这种布置特别适用于柴油发动机。
