The probability of a gas tank explosion is almost zero. An explosion would only occur if the tank is deliberately exposed to direct sunlight or subjected to open flame roasting, causing excessive internal gasification pressure, tank rupture, gas leakage mixing with air, and encountering open flames or sparks. However, this would result in an air explosion rather than the tank itself exploding. Specific details about automotive natural gas tanks are as follows: Automotive Liquefied Natural Gas (LNG) Storage Tanks: These refer to high-vacuum insulated containers installed in vehicles for storing liquefied natural gas. They feature a double-layer (vacuum) design. The inner tank is used to store cryogenic liquid LNG, with multiple layers of insulation material wrapped around its outer wall, providing superior thermal insulation. The jacket (the space between the two layers) is evacuated to a high vacuum, collectively forming an excellent insulation system. The outer shell and support system are designed to withstand the external forces generated during vehicle operation. Purpose: Automotive Compressed Natural Gas (CNG) cylinders are primarily used for long-term, fixed installation of compressed natural gas in vehicles. They offer advantages such as high pressure, large capacity, lightweight, and safety reliability. They are mainly used in taxis, minibuses, buses, and other vehicles in major and medium-sized cities.

Why is water coming out of a sedan's exhaust pipe?

The reasons for water coming out of a sedan's exhaust pipe are: 1. The water discharged from the car's exhaust pipe is accumulated water from high-speed engine operation; 2. The tailpipe at the rear of the vehicle is actually a main muffler, whose primary function is to reduce engine exhaust noise and minimize environmental pollution from vehicle noise. Since the main muffler is located at the rear of the car where temperatures are relatively low, its multi-chamber structure easily accumulates water; 3. During high-speed engine operation, the accumulated water is expelled by airflow, resulting in the common water spray phenomenon. Vehicles frequently driven at low speeds on congested roads, especially in winter, tend to experience slightly more severe water accumulation in the muffler.

How to Turn Off the Flashing Anti-Theft Light?

If the password verification is successful, the warning light will be off, allowing the engine to start. If the password verification fails, the warning light will flash at a frequency of once every 2 seconds; when the vehicle is in an unoccupied and locked state, the electronic anti-theft system is in sleep mode, and the warning light will flash at a frequency of once every 5 seconds; if the car engine anti-theft light flashes at a frequency of once every 1 to 2 seconds, it is normal, indicating that the vehicle's engine has entered the anti-theft state and the engine anti-theft function is activated. A lit anti-theft light generally indicates no issue, while an unlit anti-theft light suggests a malfunction in the vehicle's anti-theft system or the light itself, requiring timely repair.

Compulsory insurance can be purchased at the 4S shop. If you choose to insure the car in your hometown, you only need to send the vehicle identification number (VIN), engine number, car photos, and other materials to the insurance company. Wait until the insurance takes effect before driving back to your hometown for registration; 3. Apply for a temporary license plate for the new car, specifically an out-of-town temporary license plate. Make sure to drive the car back to your hometown within the validity period of the temporary license plate.

What to Do When a Tire Gets Scratched?

If a tire gets scratched, it must be removed from the rim and inspected by a professional tire dealer to determine if it can be repaired. The following situations indicate that the tire cannot be repaired: 1. The sidewall cannot be repaired. During driving, the sidewall flexes and deforms, which is a deformation zone. Repair materials may fall off, leading to air leakage. 2. If the puncture hole in the tread exceeds 6 mm in diameter, it cannot be repaired. 3. If there is damage or deformation to the bead, tread deformation, rubber corrosion by chemicals, or damage due to running flat. 4. Other abnormal conditions that make the tire unrepairable, such as visible signs of driving underinflated (e.g., sidewall scuff marks, air barrier bubbles, etc.), indicate that the tire structure may already be compromised and no longer usable.

What to Do When the Battery is Dead and the Car Won't Start?

When the battery is dead and the car won't start, the solutions include: push-starting the car, jump-starting with jumper cables, or using a portable emergency power bank to charge and start the car. Push-starting is a last-resort method and should not be used frequently, as it can cause some damage to the engine and clutch. This method should especially be avoided for automatic transmission vehicles. A car battery, also known as a storage battery, is a type of battery that works by converting chemical energy into electrical energy. The battery commonly referred to is a lead-acid battery, which is mainly made of lead and its oxides, with a sulfuric acid solution as the electrolyte.
