Why Is It Safe to Stay in a Car During a Thunderstorm?

Because a car is a metal object, its enclosed structure makes it act as a "Faraday cage." Even if the vehicle is struck by lightning, the current can pass through the car's outer shell and tires to the ground, without causing harm to the people inside. Detailed explanations of the Faraday cage are as follows: 1. Explanation One: A Faraday cage is a cage formed by metal or a good conductor, named after the surname of Michael Faraday, the founder of electromagnetism and a British physicist. It is a device used to demonstrate equipotentiality, electrostatic shielding, and the principles of high-voltage live working. 2. Explanation Two: It consists of a cage body, a high-voltage power supply, a voltage display, and a control unit. The cage body is connected to the ground, and the high-voltage power supply delivers 100,000 volts of DC high voltage to the discharge rod through a current-limiting resistor. When the tip of the discharge rod is 10 cm away from the cage body, a discharge spark occurs. According to the conditions of electrostatic equilibrium in grounded conductors, the cage body is an equipotential body with zero internal potential difference and zero electric field, with charges distributed on the outer surface near the discharge rod.

Is Toyota CVT using a steel belt or chain?

Honda's CVT uses a steel belt. Firstly, most current CVT transmissions adopt steel belt drive systems. This transmission method can alter gear ratios by adjusting pulley sizes and can handle greater torque. Honda's CVT steel belts are primarily developed in-house, with their key feature being specialized compatibility with corresponding Honda models. Durability comparison: CVT chains are generally less durable than steel belts. Primarily, CVT chains exert less impact on the cone pulleys, whereas steel belts have significantly lower strength compared to chains. Therefore, CVT transmissions using steel belts cannot withstand high torque. For instance, Nissan's CVT transmissions employ steel belts for power transmission and exhibit relatively higher failure rates. Although steel belts may generate more noise, they can endure greater torque and demonstrate superior durability.

What is the relationship between Changan NIO and NIO?

The relationship between Changan NIO and NIO: Changan NIO is a joint venture resulting from the cooperation between Changan and NIO. According to the cooperation agreement signed by Changan and NIO, Changan holds a 45% stake, NIO holds a 45% stake, and the remaining 10% is reserved for executive shareholding. The main areas of cooperation do not involve the production of complete vehicles, so Changan NIO is also referred to as a co-creation company. However, Changan NIO has officially been renamed as Avatar Technology and will operate completely independently in the market. Below is an introduction to Changan's new car: 1. Powertrain: Equipped with a 2.0T four-cylinder turbocharged engine. 2. Features: Includes front and rear parking radar, electric seat adjustment, 360° HD imaging, three-zone independent air conditioning, electric trunk, etc.

Where to Buy Flood-Damaged Cars?

Flood-damaged cars can be purchased at used car markets or repair shops. When buying a used car, it is crucial to pay attention to the vehicle's flood damage history and subsequent repairs. Overview: A flood-damaged car refers to a vehicle that has been submerged in water, typically affecting the engine and transmission. These vehicles have water levels exceeding the wheels and seats, with prolonged contact between the chassis components and water. Such cars pose significant risks, as the electrical systems are prone to short circuits and potential fire hazards. Additional Information: While flood-damaged cars can be repaired to some extent, they still carry serious hidden dangers even after repairs. The longer the immersion period, the higher the likelihood of malfunctions, and they can never be fully restored to their original condition.

Will Insurance Cover Water-Damaged Cars?

Whether an insurance company will compensate for a water-damaged car depends on whether the owner has purchased vehicle damage insurance. If vehicle damage insurance is not purchased, there will be no compensation. If it is purchased, compensation is possible. Below are the compensation scenarios for water-damaged cars under different circumstances: Car submerged while parked: If the car is submerged while parked and the owner previously purchased vehicle damage insurance, the insurance will cover the damage. If the car is damaged by falling objects or utility poles during heavy rain or while floating, these are also covered under vehicle damage insurance. Car submerged while driving with a secondary start: If the car stalls due to water while driving through flooded areas and the driver attempts a secondary start, regardless of whether the old version of water damage insurance purchased before the insurance reform on September 19, 2020, or the new version of vehicle damage insurance is in place, the insurance company has the right to deny compensation for resulting engine damage.

How to Turn Off the Frost Warning Light?

Methods to turn off the frost warning light: 1. Press the brake pedal; 2. Press the one-touch start button; 3. Run the engine until the water temperature rises to the normal level; 4. Press the one-touch start button again to turn off the engine and the vehicle's power supply; 5. Press the front hood release switch to open the front hood; 6. Disconnect the negative terminal of the battery for 10 minutes, then reconnect it to reset the frost warning light. The frost warning light is located at the bottom right corner of the tachometer and features a snowflake-like symbol. When the frost warning light illuminates, it indicates that the outside temperature has dropped significantly. A yellow light appears when the temperature is below 4 degrees Celsius, and a red light appears when it drops below 0 degrees Celsius. Due to the temperature drop, the vehicle activates its antifreeze function.

Why can't the Volkswagen brake be pressed down and the car won't start?

The reasons why the Volkswagen brake can't be pressed down and the car won't start are as follows: 1. The car steering wheel is locked: After inserting the key, turn it in the normal ignition direction, but not all the way. Gently turn it to the battery switch position. Once the car is powered on, gently move the steering wheel left and right. If the steering wheel can move, then press the brake and start the car. Remember to straighten the steering wheel when parking in the future to avoid the same problem recurring. 2. Low car battery power: In this case, after inserting the key, turn it to the battery switch position and observe whether the dashboard display behind the steering wheel is powered on. If you can't determine, turn on the headlights to confirm again. If the headlights don't light up, it confirms that the battery is dead.
