When the engine shows a yellow light, it indicates that there is a fault with the engine and it requires timely repair. The following are the reasons why the engine shows a yellow light: 1. The main reason for the engine fault light to come on: poor combustion state of the engine. 2. The internal reasons for the engine fault light to come on: unclean engine cylinder interior, with accumulated carbon deposits. Poor fuel quality. 3. Solution: Go to an auto repair shop and use a car computer diagnostic tool to check the engine system, read the fault code, and then identify the car problem. After that, carry out repairs based on the fault content. Do not attempt to repair it blindly on your own.

Should the Air Recirculation Be Turned On When Using Car Air Conditioning?

Whether to turn on the air recirculation when using car air conditioning depends on the specific conditions inside the vehicle and the driver's intention. The function of the external air circulation is to replenish fresh air. It uses a fan to draw outside air into the car, meaning the air passage between the inside and outside of the vehicle is open. The function of the internal air recirculation is to block polluted air. Below are relevant details: Function of external air circulation: When external air circulation is activated, the air intake located at the firewall is opened by the air conditioning system's computer. The car's blower then draws outside air through a micro-dust filter into the two heat exchangers (cooling and heating) inside the evaporator. The air, after passing through the heat exchangers, is blown out through the vents. When the vehicle's air conditioning system is in external air circulation mode, the air intake is open, connecting the inside and outside air. For example, if you encounter heavy traffic in the city and turn on the external air circulation, the car will be filled with exhaust fumes because the inside and outside air are connected via the external circulation. Function of internal air recirculation: In internal air circulation mode, the airflow passage between the inside and outside of the vehicle is closed. Without the blower, there is no airflow circulation. When the blower is on, the air drawn in comes only from inside the car, creating an internal airflow cycle. The internal air recirculation primarily and effectively prevents external dust and harmful gases from entering the vehicle, such as when driving through smoke, dust, areas with strong odors, or in heavy traffic, blocking harmful exhaust emissions from vehicles ahead.
