Can You Take Shelter in a Car During a Thunderstorm?

It is safe to stay inside a car during a thunderstorm. A car provides good protection during lightning weather, and there's no need to worry because the metal body of the car acts as a shield against lightning. Therefore, keeping the windows closed ensures safety inside the vehicle. Here is some relevant information: Electrostatic Induction Phenomenon: When an uncharged conductor is placed in an electric field, the free charges within the conductor move under the influence of the field, resulting in one end of the conductor becoming positively charged and the other end negatively charged. This is known as electrostatic induction. Related Principle: When a charged cloud approaches a car on the ground, the car's metal body induces opposite charges on its surface due to electrostatic induction. The car reaches electrostatic equilibrium, resulting in a zero electric field inside the vehicle. The potential at all points inside the car is equal, with zero potential difference, making it an equipotential body. Of course, if a car is struck by a powerful lightning bolt, it may cause some damage, such as a tire blowout, but the people inside the car will not be struck by lightning.

What Causes Both High and Low Beams to Suddenly Stop Working?

There are many possible reasons for a car's headlights to stop working, including: burnt-out bulbs, overheating wires, damaged relays or combination switches, open/short/circuit wiring, blown fuses, and poor circuit connections. The first step should be to check if the fuse is intact, as sudden headlight failure is most commonly caused by a blown bulb fuse. Here's some relevant information: Inspection method: When headlights stop working, check for cracks in the front headlight covers. While surface cracks may not immediately affect lighting performance, moisture can seep through these cracks into the lamp housing, which will inevitably reduce bulb lifespan. Important note: Many drivers prefer honking when overtaking on highways. However, at higher speeds, engine and wind noise make it difficult for preceding vehicles to hear horns, especially large trucks. Instead of honking when overtaking, it's more effective to flick the high beams several times by pulling the light stalk upward to alert the vehicle ahead.

Is it okay if it rains half an hour after waxing?

It's fine. Normally, after waxing a car for 30-60 minutes, the wax will dry and the car can be exposed to rain. The main purpose of waxing is to protect against the erosion of rainwater and acid rain, so it's best to perform the waxing in good weather conditions. Here is some relevant information: Waxing: Waxing is just the most basic protective measure in car care, so the protection doesn't last very long. Generally, after two or three weeks, the effect of waxing will mostly disappear. If you want longer-lasting protection, you can opt for glazing or even crystal coating to protect the car's paint. Glazing usually provides protection for about three to four months, while crystal coating can last for about a year. Precautions: New cars should not be waxed casually because the paint layer of a new car already has a protective wax. Waxing too early can remove the original wax on the new car's surface, causing unnecessary waste. Generally, there's no need to rush to wax a new car within five months of purchase.

Should the car cover be removed on windy days?

It is best not to use a car cover, as the friction between the cover and the car can cause more damage to the vehicle. Here is some relevant information: Car cover: Commonly known as a car garment, it is an outer cover made of canvas or other flexible and wear-resistant materials according to the car's dimensions, serving as a protective accessory for the vehicle. It provides good protection for the car's paint and windows, especially for high-end cars. Regular use of a car cover can extend the lifespan of the paint, keeping it shiny and new. Functions of a car cover: Besides cleaning and sun protection, a car cover also has excellent water-repellent properties, preventing damage from freezing in extremely cold weather; effectively protecting the car from falling objects, fireworks, and other accidental factors; and providing security against theft of the vehicle and its accessories. However, the use of a car cover should be moderate. Owners without parking spaces should definitely have one, but it should not be used every day even if available.

What kind of oil should be used for an air compressor pump?

It mainly depends on the type of air compressor. Small air pumps generally use mechanical oil, with viscosity not too high. For compressors above 0.6 cubic meters, special air compressor oil should be used. For high-pressure compressors or those with large air production in factories that operate continuously, the oil number specified in the manual should be selected, usually model 32 or 46. There are also mineral oil, semi-synthetic oil, and full synthetic oil, which should be selected based on the region and the size of the air compressor. Below is relevant information: Maintenance items: For new machines, the lubricating oil must be replaced after 5 hours of operation, and then every 500 hours of operation thereafter. Check the lubricating oil daily and open the drain valve of the air storage tank once a day to discharge oil and water. Clean or replace the air filter element every half month, which can be adjusted according to the environment. Air compressor: Air compressor generally refers to a device used to compress gas. The structure of an air compressor is similar to that of a water pump. Most air compressors are reciprocating piston type, rotary vane, or rotary screw. Centrifugal compressors are used for very large applications.
