Why does the idle speed increase when the air conditioner is turned on?
1 Answers
When the air conditioner is turned on, the engine requires additional power to drive the compressor, increasing fuel injection to supplement power, which results in a higher idle speed. Below is an introduction to car air conditioner maintenance: 1. Do not arbitrarily adjust the air outlet direction: When using the air conditioner, not paying attention to adjusting the direction of the air flow is not conducive to achieving the best effect of the air conditioner. According to the principle that cold air sinks and hot air rises, the correct approach should be to point the air outlet upward when cooling and downward when heating. 2. Regularly start the air conditioner in winter: Not using the air conditioner for a long time can cause its rubber seals to age, and the lubricating oil on the internal components will dry out. Regularly starting the air conditioner allows the components to be lubricated, maintaining good condition. Therefore, it is best to start the air conditioner once a week in winter. 3. Avoid using the air conditioner for too long each time: Keeping the air conditioner on for a long time after getting in the car can cause excessive pressure on the condenser, which can damage the cooling system. Therefore, it is advisable not to use the air conditioner for too long each time. If the temperature inside the car has reached a comfortable level, you can turn off the air conditioner and turn it on again after a while. 4. Ventilate and cool down before driving in summer, then switch to internal circulation: When you first enter the car, you should open the windows for ventilation and turn on the external circulation to expel the hot air. After the temperature inside the car drops, switch to internal circulation.
