Leaving the car sunroof open during rain can indeed be harmful to the vehicle. Here is the relevant information: 1. Interior moisture: This can lead to dampness inside the car, making the interior upholstery prone to mold and mildew, and damaging leather seats. 2. Significant water ingress: If a large amount of water enters, the excessive moisture can cause electrical circuit short circuits. If water enters the engine, it may render the engine unusable. When driving in the rain, ensure all doors, windows, and the sunroof are tightly sealed to prevent rainwater from entering and causing dampness inside the vehicle. 3. Rainy driving precautions: (1) If you forget to close the sunroof and rainwater enters, the first step is to dry the interior. Wipe up any standing water and ventilate the car. Replace seat and floor mats, and dry them in the sun when possible. You can also place a dehumidifier box inside the car to absorb moisture. (2) For leather items that get wet, use towels or paper towels to dry them as much as possible. However, avoid exposing leather items to direct sunlight; let them air dry naturally. Also, wipe away any water near electrical circuits to prevent prolonged exposure to moisture, which could lead to short circuits or even electric shocks. After the car has been exposed to rain, ensure good ventilation inside the vehicle once the weather clears, and check if the drainage channels on the windshield are clear.

What is the Fuel System?

The fuel system is generally composed of components such as the fuel pump, fuel filter, and fuel injector. Its function is to ensure the required fuel flow for the engine under various working conditions and states. Below is some introduction to the fuel system: 1. The fuel system handles fuel filling and transportation, ensuring that fuel smoothly reaches the engine to power it. It is also responsible for collecting fuel vapors and filtering them before releasing them into the atmosphere. 2. The principle of adsorption and desorption in its evaporation system is that fuel vapors are generated in the fuel tank due to changes in environmental temperature. When the vapor pressure exceeds the system's set pressure, the system's bidirectional valve opens, allowing the vapors to enter the charcoal canister, where they are adsorbed by activated carbon.

Why is water dripping from the exhaust pipe after the engine is turned off?

There are three main reasons for water dripping from a car's exhaust pipe: 1. Water vapor that evaporates immediately after being emitted—this usually occurs when a car is started for the first time in winter or during the rainy season. However, once the engine temperature rises, the white smoke will disappear, which is normal and requires no concern or maintenance. 2. If the exhaust pipe emits black smoke after the engine temperature rises, this indicates that the engine is burning oil. Be cautious and check the oil level before driving. If the oil turns black, it suggests low cylinder pressure or a non-functioning cylinder, which should be inspected and resolved at a repair station. 3. If the exhaust pipe emits a large amount of white water vapor while the engine is running, it indicates low cylinder pressure or a non-functioning cylinder, which should be inspected and resolved.

How to Determine When Engine Oil Needs to Be Changed?

Pull out the dipstick, then drip the oil from the dipstick onto a tissue paper to observe the color and viscosity of the oil. If the color appears quite black, it should be changed. Below are specific details about engine oil: 1. Generally, fully synthetic oil needs to be changed every eight thousand to ten thousand kilometers. 2. Engine oil is referred to as the lifeblood of the engine. Inside the engine, oil not only lubricates but also cleans, seals, buffers, prevents rust, and dissipates heat. Without oil, the engine cannot operate. During engine operation, the oil forms a thin film on the surfaces of various components inside the engine, preventing direct contact and friction between them.

Should You Look at the Front or Rear Door Handle When Reversing into a Parking Space?

When reversing into a parking space, focus on the rear door handle. While adjusting direction, keep the car in reverse gear and maintain the steering wheel at its extreme left position as you back up. The driver should observe the left rearview mirror and make directional adjustments to guide the rear of the car into the parking space. Once the car is inside the space, the driver should check the right rearview mirror. When the entire right boundary line of the parking space becomes visible, immediately straighten the steering wheel. Different items in Subject 2 of the driving test have different penalty points. The details are as follows: 1. General Penalties: Not wearing a seatbelt, not closing the car door properly, and starting the engine without the gear in neutral all result in a 100-point deduction. Failing to use turn signals, using turn signals for less than three seconds, forgetting to turn off turn signals, or using them incorrectly, as well as stalling the engine, each result in a 10-point deduction. 2. Parallel Parking: If the car body crosses the line after stopping inside the parking space or if the task takes more than 90 seconds, a 100-point deduction applies. Not using or incorrectly using turn signals when exiting the parking space also results in a 100-point deduction. Each time the car body touches the parking space line or the wheels touch the lane boundary line during movement, a 10-point deduction is applied. Stopping for more than 2 seconds during the process results in a 5-point deduction each time. 3. Reversing into a Parking Space: Exceeding 210 seconds, not following the prescribed route or sequence, failing to drive the front wheels over the control line before reversing, or not successfully parking the car all result in a 100-point deduction. Stopping for more than 2 seconds during the process results in a 5-point deduction each time. 4. Curve Driving: Driving over the edge line or stopping for more than 2 seconds results in a 100-point deduction.
