There are two types of vehicle fire extinguishers: one is the fire extinguisher canister, which has a validity period of 8 years; the other is the extinguishing agent, which has a shorter validity period of about one year. Below is some information about fire extinguishers: 1. Main types: They are divided into aerosol fire extinguishers, dry powder fire extinguishers, ultra-fine dry powder fire extinguishers, carbon dioxide fire extinguishers, and water-based fire extinguishers, mainly used to prevent vehicle fires. 2. Precautions for using fire extinguishers: Purchase them from reputable fire equipment stores. Fire extinguishers should be placed in dry, well-ventilated, and easily accessible areas, away from open flames, high temperatures, and greasy areas. Regularly check if the safety seal is intact, and unauthorized installation of electrical devices is strictly prohibited.

I've been driving for almost 20 years and always prioritize car fire extinguisher safety. The so-called expiration date isn't a fixed number of years, but rather depends on regular maintenance. There's a pressure gauge on the extinguisher - when the needle is in the green zone, it's functional; if it points to red or yellow, the pressure might be insufficient and it could fail. Typically, dry powder extinguishers have a shelf life of 5 to 10 years, but I recommend checking the gauge every six months to ensure reliability after bumps or exposure to high temperatures. Many people overlook this - last year I noticed my gauge was off and immediately replaced it. A new one costs just a few dozen yuan, but it's extremely dangerous if it fails in an emergency. Remember, safety is no trivial matter - don't wait for an accident to regret. With proper maintenance, it might last over 10 years, but beyond that the powder may clump, so replacing it is safer.

What is the passing score for the driver's license test?

Here is an introduction to the passing standards for each subject of the driving test: 1. Subject 1 passing standard: The full score is 100, and a score of 90 or above is considered passing. 2. Subject 2 passing standard: The full score is 100, with evaluation criteria set for failing, deducting 20 points, deducting 10 points, and deducting 5 points. For applicants of large buses, trailers, city buses, medium buses, and large trucks, a score of 90 or above is passing; for other types of vehicles, a score of 80 or above is passing. 3. Subject 3 passing standard: The full score is 100, with evaluation criteria set for failing, deducting 20 points, deducting 10 points, and deducting 5 points. For applicants of large buses, trailers, city buses, medium buses, and large trucks, a score of 90 or above is passing; for other types of vehicles, a score of 80 or above is passing. 4. Subject 4 passing standard: The full score is 100, and a score of 90 or above is considered passing.

What is the official wading depth of the BYD Tang?

The maximum wading height of the BYD Tang is 170mm. The wading depth of the BYD Tang is determined by the height of the vehicle chassis, which is the ground clearance listed in the model's parameter configuration table. Generally, the greater the ground clearance, the higher the chassis, and the higher the safety factor when passing through waterlogged roads. Therefore, in terms of safe wading depth, the advantages of off-road vehicles and SUVs are obvious. However, for most compact and small cars with low chassis, the position of the vehicle's air intake should be used as a benchmark when passing through waterlogged roads. If the air intake of the BYD Tang is below the water level during wading, water will be sucked into the engine cylinders. Since water cannot be compressed like air, it will cause severe damage to the engine's mechanical components (such as connecting rods, pistons, crankshafts, etc.). Therefore, the wading depth should not exceed the height of the engine air intake. Alternatively, installing a snorkel can increase the height of the engine air intake, thereby improving the maximum wading depth. If wading is unavoidable, the following safe and correct operations should be performed: Before wading, always turn off the auto start-stop function to prevent the engine from automatically restarting after stalling in water, which could cause severe damage due to water ingress. Assess the underwater road conditions based on the passage of vehicles ahead and choose an appropriate entry point. Observe the path taken by other vehicles and follow their tracks at low speed, avoiding sudden acceleration or deceleration. On roads prone to water accumulation, use warning water level markers, trees, or other vehicles' wheels and doors as references to judge the water depth before deciding whether to proceed. Know your vehicle's safe wading depth. If the water depth exceeds half of the tire height or the engine air intake, do not proceed recklessly; consider taking an alternative route.

Should Flood-Damaged Cars Be Scrapped Directly?

Flood-damaged cars can be scrapped directly. Here are the relevant details: 1. Safety Hazards: If a vehicle is submerged in water, it can easily cause body parts to rust, shortening its lifespan and reducing safety performance. For example, water damage can lead to corrosion and rusting of the vehicle's wiring, causing sudden engine shutdown or spontaneous combustion due to short circuits while driving, with unimaginable consequences. 2. Lifespan: Check whether the protective coating on the bottom of the body is damaged. Replace the fuel filter and spark plugs. Inspect the multi-ribbed belt and replace it if necessary. Check if the engine timing belt is cracked or damaged and replace it if needed. Ensure the engine oil pan bolts are not loose and tighten them to the specified torque if necessary. Inspect the brake hoses for aging or damage, check the brake hard lines for damage or corrosion, and ensure there are no leaks at any connection points.

What Causes a Sudden Increase in Fuel Consumption for the Magotan?

The sudden increase in fuel consumption for the Magotan is due to engine malfunction and insufficient power. There are three methods to reduce vehicle fuel consumption: 1. Minimize vehicle weight: Keep the interior simple and avoid carrying unnecessary items, as every additional kilogram increases fuel consumption by 1%; 2. Avoid excessive modifications: Adding spoilers, protective covers, or wings can disrupt the original aerodynamic design, increasing wind resistance and consuming extra fuel. Modifying lighting systems increases electrical load, leading to unnecessary fuel consumption; 3. Develop good driving habits: Avoid sudden acceleration, driving at high speeds in low gears, prolonged idling, frequent lane changes, or braking. Aim for smooth starts, steady-speed driving, and reduced braking.

How Often Should Fully Synthetic Motorcycle Oil Be Changed?

Fully synthetic motorcycle oil should be changed every 10,000 kilometers or once a year. Fully synthetic oil not only functions to lubricate, clean, and repair but also has strong environmental adaptability. Motorcycle oil, short for motorcycle engine lubricating oil, typically includes motorcycle gear oil and motorcycle shock absorber oil. Motorcycles generally use gasoline engines, and the quality grade of motorcycle oil usually follows the American Petroleum Institute's quality classification for gasoline engine oil, known as API classification. The specifications include: SA, SB, SC, SD, SE, SF, SG, SH, SJ, SL, SM, SN.

What to Do When Abnormal Tire Pressure Occurs in a Car?

Solutions for abnormal tire pressure in a car: 1. Check if the tire pressure is too low. If so, a tire pressure reset is needed; 2. If it's not due to low tire pressure, it may be a tire pressure monitoring system fault. Generally, a faulty wheel speed sensor can cause the brake system warning light to illuminate, and it is recommended to visit a repair shop for a reset. Tire pressure refers to the air pressure inside the tire, and its level plays a crucial role in the car's performance and power. Car tires are one of the important components of a vehicle, directly in contact with the road surface, working together with the car's suspension to mitigate impacts during driving, ensuring good ride comfort and smooth driving.
