What is the difference between cruise control and ACC adaptive cruise control?

Here are the differences between cruise control and ACC adaptive cruise control: 1. Different performance: ACC adaptive cruise control allows the vehicle's cruise control system to adjust speed to adapt to traffic conditions, while traditional cruise control only maintains a constant speed. 2. Different methods: ACC adaptive cruise control is intelligent and can control the vehicle speed through sensors. Traditional cruise control is mechanical and requires the driver to step on the brake to control the speed. 3. Different functions: The function of cruise control is to automatically maintain the speed set by the driver without stepping on the accelerator pedal, allowing the vehicle to travel at a fixed speed. However, cruise control has an obvious disadvantage, which is that it can only provide a relatively constant driving speed compared to adaptive cruise control.

I'm used to driving with cruise control, and there's quite a difference between regular cruise control and adaptive cruise control. To put it simply, regular cruise control is just a fixed speed maintainer—set it to 120 km/h, and it'll charge ahead without caring if the truck in front slows down, leaving you to hit the brakes yourself. Adaptive cruise control, on the other hand, is like having a co-driver; the front radar keeps an eye on the vehicle ahead, automatically adjusting speed accordingly. Last time I was stuck in highway traffic, I set the adaptive cruise to the shortest following distance, and it slowed down to 30 km/h and inched forward on its own, completely freeing up my right foot. But on rainy days, you have to be careful—sensors covered in mud might malfunction.

Can BMW Run-Flat Tires Be Replaced with Regular Tires?

BMW run-flat tires can be replaced with regular tires. However, it is essential to carefully check the wheel rim specifications and other details to ensure the new tires match the original vehicle specifications, preventing any deviation in driving trajectory. When replacing with regular tires, it is advisable to replace all four tires. Mixing run-flat tires with regular tires can significantly impact handling. The size, load rating, and speed rating of the new tires must not be lower than those of the original tires. Drivers should exercise caution, perform regular inspections, and promptly remove debris or stones from the tires. Additionally, keeping a spare tire in the trunk is recommended for emergencies. Run-flat tires, also known as zero-pressure tires, are designed to function normally even when punctured. The primary difference between run-flat tires and regular tires lies in the thicker sidewalls of the former. Run-flat tires consist of an outer tire, a standard inner tube, a spare inner tube, a steel rim, and a gas generator. They are marked with special symbols after the tire sidewall specifications, which regular tires lack. The biggest advantage of run-flat tires is their ability to continue driving at speeds up to 80 km/h even after complete air pressure loss, eliminating the need for immediate tire replacement.

Can a Hybrid Car Run as a Gasoline Car After Removing the Battery?

Hybrid cars cannot operate as gasoline cars after removing the battery. A hybrid car is not simply a gasoline car with an added electric motor and battery; many of its systems are interconnected with the electric motor and power battery. If the battery is removed, numerous systems will cease to function. Additionally, unauthorized removal of the battery can pose safety hazards, so it is advised not to dismantle the battery pack of a hybrid car. Plug-in hybrid electric vehicles (PHEVs) are classified as new energy vehicles and require green license plates. These vehicles offer longer electric-only driving ranges, better fuel economy, and lower emissions compared to conventional vehicles.

Should You Use Hot or Cold Air to Defog a Car?

Both hot and cold air can be used to defog a car, but cold air works faster, though it may cause fogging to recur. Warm air defogs more slowly but eliminates the risk of recurring fogging. The rear windshield is defogged using heating wires, while the front windshield cannot accommodate these wires, so the car's air conditioning system is used for defogging. There are air vents located below the front windshield that direct airflow onto it. The air conditioning control panel also features a windshield defogging button. In winter, warm air is typically used to defog the front windshield, while in summer, cold air is generally preferred.

Should Car Maintenance Be Based on Time or Mileage?

Car maintenance can be based on either time or mileage, whichever comes first. For a new car, the first maintenance should be done within 3 to 5 months or when the mileage reaches 3,000 to 5,000 kilometers. In addition to changing the engine oil and oil filter, the first maintenance also includes a comprehensive inspection and diagnosis of the vehicle's condition and usage. The first maintenance items include: replacing the engine oil and oil filter, cleaning the air filter, checking the levels of various fluids, inspecting the generator belt and wiper blades for damage, checking tire pressure and condition, and examining the chassis and all switches in the vehicle.

What is the difference between the internal and external circulation modes of a car's air conditioning system?

The difference between the internal and external circulation modes of a car's air conditioning system lies in their working principles: Internal circulation mode closes the airflow passage between the interior and exterior of the vehicle. Without the fan running, there is no air circulation. When the fan is activated, the air drawn in comes solely from inside the vehicle, creating an internal airflow cycle. External circulation mode uses the fan to draw outside air into the cabin, maintaining an open air passage between the exterior and interior. The air blown by the fan originates from outside the vehicle, and even without the fan operating, airflow is naturally drawn into the cabin while driving. Car air conditioning, short for automotive air conditioning system, is designed to regulate and maintain optimal conditions for temperature, humidity, air cleanliness, and airflow within the passenger compartment. Its primary functions are to provide a comfortable environment for passengers, reduce travel fatigue, create favorable working conditions for the driver, and ensure driving safety.
