[Dennis]

Idling with the air conditioning on can consume 20% to 40% of the fuel in the car, increasing fuel consumption by 25% per 100 kilometers. Here is the relevant information: 1. Car Air Conditioning: The car air conditioning system, abbreviated as car AC, is used to regulate and control the temperature, humidity, air cleanliness, and airflow inside the car cabin to optimal conditions. It provides a comfortable environment for passengers, reduces travel fatigue, and creates good working conditions for the driver, playing an important role in ensuring safe driving. 2. Idling: Idling is an operating condition of a car where the engine runs in neutral gear. The engine speed during idling is called the idle speed. The idle speed can be adjusted by modifying the throttle size and other methods.
