What should be checked in the vehicle before a long-distance trip?

Before a long-distance trip, the following parts of the vehicle should be checked: 1. Check whether the oil level is within the normal range and whether it needs to be replaced, and whether the coolant level and quality are normal. 2. Check whether the tires are in good condition. 3. Check whether there are any faults in the electronic control system. 4. Check whether all the lights are functioning properly. 5. Check whether the onboard tools are complete.

What is the normal charging voltage and current for a car battery?

For a 12V battery, the open-circuit voltage when fully charged is generally around 13.0V. If the voltage meets this requirement, you can further test the capacity or attempt to start the engine. If it works, the battery is normal; if not, the battery may need replacement. A portable charger can be used to charge the battery, typically requiring about 20 hours for a car starting battery. After charging, perform a battery test to check if the charge was successful. Below are some relevant details about car battery charging: 1. When charging, connect the battery's positive terminal to the charger's positive terminal and the battery's negative terminal to the charger's negative terminal. 2. The initial charging process is divided into two stages: First, charge with the initial charging current until the electrolyte releases bubbles and the cell voltage rises to 2.3—2.4V. Then, reduce the current to half of the initial charging current and continue charging until the electrolyte releases vigorous bubbles, and both the characteristics and voltage remain stable for 3 hours. The total charging time is approximately 45—65 hours. The temperature should be controlled between 35—40°C. If the electrolyte specific gravity does not meet the required standard after the initial charging, adjust it using distilled water or an electrolyte with a specific gravity of 1.4. 3. During the charging process, frequently measure the electrolyte temperature. If necessary, reduce the current by half, stop charging, or cool the battery to maintain the temperature between 35~40°C. If the electrolyte specific gravity does not meet the required standard after the initial charging, adjust it using distilled water or an electrolyte with a specific gravity of 1.4. After adjustment, continue charging for 2 hours until the specific gravity meets the required standard.

How to Set the Locking Horn Sound for BYD Vehicles?

Here are the methods to set the locking horn sound for BYD vehicles: 1. Set via the in-car central control. Find the "Vehicle Settings" option in the car's system, then enter the "Control Page." Enable the "Locking Sound Alert" on the control page, and the horn will sound once when locking the car; 2. Set via the key. If the car key has a mute button, simply press the mute button towards the car to turn the locking sound alert on or off; 3. Modify ECU settings. If the car does not have a mute button and cannot be set in the car's system, you will need to visit a 4S shop to have a technician modify the ECU data.

Why does the car shake when starting?

There are several reasons why a car may shake when starting: 1. It could be due to severe carbon buildup inside the engine, making it difficult to start the vehicle and causing idle shaking. 2. There might be an issue with the vehicle's ignition system. It's necessary to check the spark plugs and high-voltage wires. If the ignition system isn't functioning properly, it can lead to idle shaking or difficulty starting. 3. Unstable fuel pressure in the vehicle's fuel system. If the fuel pump can't supply fuel to the vehicle normally, it may result in poor fuel atomization or failure to open the fuel injectors, causing cylinder misfire shaking or failure to start. 4. Insufficient engine cylinder pressure. Over time, the vehicle's engine may have exceeded its service life and can no longer function properly, leading to intermittent idle shaking. In such cases, immediate repair at a service center is necessary.

What is the plastic panel under the bumper called?

The plastic panel under the bumper is called a deflector. Function of the deflector: The deflector is usually fixed with screws or clips and can be removed by oneself. The main function of the deflector is to reduce the resistance generated during high-speed driving. The deflector is a downward-sloping connecting panel installed below the front bumper, integrated with the front skirt of the car body. This design helps to lower the air pressure under the car and reduces risks during driving, also preventing rear-wheel drift. If the deflector is missing, the difference in air pressure above and below the car at high speeds can create an upward lifting force, which not only increases fuel consumption but also affects the car's driving safety. Plastic shield above car wheels: The curved shield above the car tires is called a mudguard. Function of the mudguard: The main function of the mudguard is to prevent mud from splashing onto the car body or people, keeping them clean. It also prevents mud from splashing onto tie rods and ball joints, which could cause premature rusting. Another function is to protect the car's exterior paint from damage caused by road mud. Mudguards are typically made of high-quality rubber or engineering plastic. Plastic shield under the front chassis: The plastic shield under the front chassis protects the engine and is called a chassis guard. The chassis guard protects engine components and various pipelines, preventing damage from friction with the ground under rough road conditions. It also improves airflow under the car, reducing wind resistance and noise, thereby enhancing fuel economy and overall vibration and noise performance.
