The difference between internal circulation and external circulation in a car: Internal circulation refers to the air inside the car being heated or cooled and then recirculated back into the cabin. External circulation refers to drawing air from outside the car, heating or cooling it, and then introducing it into the cabin, effectively exchanging air between the inside and outside of the vehicle. Relevant information about car air conditioning is as follows: Introduction: The car air conditioning device (air-conditioning-device), commonly referred to as car air conditioning. Function: It is used to regulate and control the temperature, humidity, air cleanliness, and airflow within the car cabin to optimal conditions, providing a comfortable environment for passengers and reducing travel fatigue; it also creates favorable working conditions for the driver and plays a crucial role in ensuring safe driving as a ventilation device.

What does avg mean on a car?

AVG on a car is the abbreviation of average, which means the average value. It can be adjusted through buttons or other parts (such as on the turn signal lever) to display various average values on the instrument panel, such as average fuel consumption per kilometer, average speed per 100 kilometers, average fuel consumption per 100 kilometers, etc. The specific display depends on the vehicle's own program. More information about AVG is as follows: 1. Calculation formula: The basic calculation method is the fuel consumption per 100 kilometers, which is the actual fuel consumption divided by the actual distance traveled. That is, fuel consumption per 100 kilometers = fuel consumption (liters) ÷ distance traveled (kilometers) * 100. 2. Speedometer: The speedometer actually consists of two meters. One is the speedometer, and the other is the odometer. For example: km/h-avg is the average speed, and L/km-avg represents the average fuel consumption per unit.

Can you turn right when there is no right turn arrow at a red light?

Right turns generally have more freedom compared to left turns. When the straight arrow is red and there is no right turn signal, you can turn right. Here is relevant information about turning right at a red light without a right turn arrow: 1. According to traffic laws, if there is no right turn signal or a dedicated right turn auxiliary lane at the traffic light. 2. If there are no specific signs indicating that right turns are prohibited at the red light at the intersection, vehicles can turn right when the traffic light is red. 3. When turning right in the right turn lane, if there is only one straight lane, you must wait for the arrow to turn green before turning right. 4. If the traffic signal has a right turn arrow, you definitely cannot turn right when the right turn arrow is red, even if the straight arrow is green. Turning right is not allowed when the right turn arrow is red.

Under what circumstances will the car ABS activate?

ABS system will activate during emergency braking, and strong braking on slippery or icy roads will also trigger the ABS system. Here is relevant information about car ABS activation: 1. ABS stands for Anti-lock Braking System. During emergency braking, the ABS system allows the wheels to maintain a rolling and sliding state. 2. ABS prevents wheel lock-up during hard braking, as locked wheels can cause the vehicle to skid and lose control. 3. If all wheels are locked, the driver cannot control the vehicle's trajectory through the steering wheel. ABS is designed to enable the driver to decelerate promptly in emergencies while maintaining control over the vehicle's path to avoid obstacles ahead. 4. Without ABS, the vehicle would quickly lose control. The ABS system prevents this by keeping the wheels in a rolling and sliding state during emergency braking, essentially performing intermittent braking on the wheels. 5. ABS can apply braking to the wheels 60 to 120 times per second.

Can Car Scratches Be Repaired by Yourself?

Yes, car scratches can be repaired by yourself as follows: Touch-up Paint Pen: If the rust is not severe, you can first use very fine sandpaper dipped in water to gently sand away the rust spots. However, avoid sanding randomly without direction; sand in straight lines in the same direction. After completely cleaning it, apply a layer of primer. For new scratches, you can clean them and directly apply the primer. Then, if the vehicle comes with a small can of original factory paint, you can wait for the primer to dry, sand it smooth with water sandpaper, and apply the original factory paint over the primer. Applying Toothpaste Can Temporarily Prevent Rust: Another method is to use ordinary toothpaste. When you find new small scratches on the car body, gently apply the toothpaste in a circular motion over the scratch. After rain or washing the car, don't forget to reapply. This can generally reduce the visibility of the scratch and also simply act as a barrier to prevent rust in the short term.
