What Causes the Engine Noise to Increase When Turning on the Air Conditioning?
1 Answers
The reason why the engine noise increases when turning on the air conditioning is that after activating the cooling function of the air conditioning, the engine needs to drive the compressor to operate. At this time, the engine's idle speed will increase, leading to louder engine noise, which is a normal phenomenon. The function of the car air conditioning is to adjust and control the temperature, humidity, air cleanliness, and air flow inside the car compartment to an optimal state according to the set temperature, providing a comfortable riding environment for passengers and reducing travel fatigue. The method of using the air conditioning is: 1. After starting the vehicle, turn the air conditioning knob to the cooling or heating area; 2. Press the AC button when cooling is needed.
