It is generally recommended to refuel when the tank is about one-quarter full. Below is an introduction to fuel tanks: 1. General Classification: Fuel tanks can be divided into two types: open tanks and closed tanks. Open tanks have a liquid surface that is in contact with the atmosphere, and an air filter is installed on the tank cover. Open tanks are simple in structure, easy to install and maintain, and are commonly used in hydraulic systems. Closed tanks are typically used for pressurized tanks, filled with a certain pressure of inert gas, with a charging pressure of up to 0.05MPa. 2. Classification by Shape: Fuel tanks can also be categorized into rectangular tanks and cylindrical tanks. Rectangular tanks are easier to manufacture and allow for easy placement of hydraulic components, making them widely adopted. Cylindrical tanks offer high strength, are lightweight, and easy to clean, but they are more difficult to manufacture and occupy more space, often used in large metallurgical equipment.

I usually refuel when there's about a quarter of the tank left, which is a safer approach. If you wait too long, like when the fuel warning light comes on, the fuel pump may overheat and get damaged due to lack of fuel for cooling. Those components at the bottom of the tank can stir up sediment when sucking fuel, potentially clogging the system. Once, I forgot to refuel and had trouble starting the car when it was nearly empty. The mechanic later said it might be a faulty fuel pump. Typically, refueling at 25% to 30% remaining is a good practice to prevent unexpected breakdowns in remote areas. Additionally, inaccurate fuel gauges are common, so refueling early avoids misjudgment and gives you some leeway. You can easily do it while running errands or on your way to work without wasting time. Since adopting this habit, my car has been in good condition with no fuel-related issues. Just remember this ratio, and it's easy to manage.

Why is the CarPlay in my car gray?

The gray CarPlay in your car indicates that it has not been connected yet. Use a USB cable to connect your iPhone, then open CarPlay on your phone and establish the connection with the car's CarPlay system. Here is an extended introduction: Extended introduction to CarPlay: Simply put, it maps functions such as phone calls, text messages, navigation, and music from your iPhone to the car's multimedia system, but it only supports Apple devices with a Lightning interface. The combination of CarPlay and "Hey, Siri" also enables voice control functionality in the vehicle.

What is the principle of slipstreaming?

The principle of slipstreaming is that when you get close to the car in front, the leading car blocks the wind resistance for you, reducing pressure and creating a tendency to accelerate. Here are methods to counter slipstreaming: 1. Activate Nitrous: When the distance to the trailing driver is close, simply activate nitrous to increase the gap. If nitrous is insufficient, you can use a quick drift to trigger a mini-boost, gathering nitro while shifting position to disrupt the opponent's slipstream and nitro collection. 2. Use your car to block: Alternatively, use your car to block, positioning your vehicle to obstruct the trailing car and deter any overtaking attempts.

Why Does Paint Chip Off So Easily on New Cars?

It is quite common for car paint to be chipped by small stones, which may occur when driving through sandy or dusty road sections, or when hit by stones kicked up by the vehicle in front. Below is an introduction to new car maintenance: 1. Paint Maintenance: An essential part of "automotive surface care." 2. Air Conditioning Maintenance: It is actually necessary to clean the car air conditioning periodically because the ducts accumulate a lot of fine dust particles. Over time, mold can develop, and bacteria can be blown into the car through the ducts. Drivers often sit in the car for hours, breathing in such toxic air, which can be very harmful to health.

How to Connect the Positive and Negative Terminals When Jump-Starting a Car?

Method for connecting the positive and negative terminals when jump-starting a car: Connect the positive terminals of both car batteries together, and then connect the negative terminals. Below are precautions for jump-starting a car: 1. During use: Connect the positive terminal first when jump-starting, and disconnect the negative terminal first when finished. 2. When starting: If the car fails to start, listen for sounds. If you hear a warning sound, it indicates insufficient battery power. If there is still a cranking sound from the engine, it might be another issue. 3. If unable to start: If the car still fails to start after a prolonged jump-start, check if the two car batteries have the same power capacity, and consider using a cable with better conductivity.

How many points are deducted for going straight and turning?

Turning left from a straight lane deducts 3 points and incurs a fine. According to the "Scoring Standards for Road Traffic Safety Violations," Article 3: If a motor vehicle driver commits any of the following violations, 3 points will be deducted: Point 8: Driving a motor vehicle in violation of prohibition signs or prohibition markings. Below is additional information: Vehicle driving precautions: Maintain a safe following distance. According to relevant tests, when braking suddenly at a speed of 100 km/h, even the best car requires nearly 40 meters of braking distance. Even if the speed in urban areas does not reach 100 km/h, it is still impossible to guarantee that the vehicle can come to a complete stop immediately under normal driving conditions.
