The present disclosure provides methods and systems for radiator fan operation for charge air cooler de-icing. Methods and systems are provided for reducing ice formation in a charge air cooler. In one example, a method includes operating a radiator fan of a vehicle in a first direction to cool an engine of the vehicle; and reversing a rotation direction of the radiator fan to blow the heated air toward a charge air cooler disposed near a radiator of the vehicle. Operating the radiator fan in a first direction may be based on engagement of one or more gears of a transmission of the vehicle, while operating the radiator fan in a reverse direction may be based on engine temperature conditions, one or more ambient weather conditions, and engine idle conditions.
本公开提供了“用于增压空气冷却器除冰的散热器风扇操作的方法和系统”。提供了用于减少增压空气冷却器中冰的形成的方法和系统。在一个示例中,一种方法包括:沿第一方向操作车辆的散热器风扇以冷却车辆的发动机;以及使散热器风扇的旋转方向反向以将加热后的空气吹向增压空气冷却器,所述增压空气冷却器布置在车辆的散热器附近。沿第一方向操作散热器风扇可以基于车辆的变速器的一个或多个挡位的接合,而沿反向方向操作散热器风扇可以基于发动机温度状况、一个或多个环境天气状况以及发动机怠速状况。
