How does the air flow in the engine?
In order to improve the cooling capacity of the radiator, the fan is forced to ventilate behind the radiator. The former car radiator fan is driven directly by the crankshaft belt, the engine will start it to rotate, can not see the engine temperature changes, in order to regulate the cooling power of the radiator, to control the wind into the radiator with movable shutters. Now the fan electromagnetic clutch or electronic fan is widely used, when the water temperature is relatively low, the clutch and the rotating shaft are separated, the fan does not move, when the water temperature is relatively high, the temperature sensor is connected to the power supply, so that the clutch and the rotating shaft are connected and the fan rotates. Similarly, the electronic fan is driven directly by an electric motor, and the motor is operated by a temperature sensor. The operation of these two types of radiator fans is actually controlled by temperature sensors.
