    • A system for variable engine compartment ventilation in a slim and compact unit with components used in non-related industries. The system can have at least one bank of movable louvers rotatably mounted within a louver frame for guiding a flow of air into a vehicle engine compartment; a motor to rotate the louvers with a motor gear formed on an output shaft rotatably connected in parallel to at least one helix cable by a helix cable drive gear and a louver pinion gear integral with each louver engaging the helix cable along its length; and a control unit for operating the assembly of movable louvers in response to an output signal from a vehicle communication bus. The output signal of the vehicle communication bus can be in response to input from an engine coolant temperature sensor or a vehicle speed sensor.
    • 一种用于可变发动机舱通风的系统,其体积小巧且紧凑,具有用于非相关行业的部件。 该系统可以具有可旋转地安装在百叶窗框架中的至少一个可移动百叶窗组,用于将空气流引导到车辆发动机舱中; 电动机,用于通过螺旋电缆驱动齿轮与与至少一个螺旋电缆平行旋转连接的输出轴上的马达齿轮旋转百叶窗,以及沿着其长度与每个百叶窗一体地接合螺旋缆索的百叶窗小齿轮; 以及控制单元,用于响应于来自车辆通信总线的输出信号操作可移动百叶窗的组件。 车辆通信总线的输出信号可以响应于来自发动机冷却剂温度传感器或车速传感器的输入。
