What Causes the Squeaking Noise from Car Door Seals on Rough Roads?

There are several possible causes for the squeaking noise from car door seals when driving on rough roads. Door-related noise: If you are unsure whether the noise is coming from the front or rear door, find a bumpy road to ensure the noise occurs at low speeds. While wearing a seatbelt and ensuring driving safety, slowly open the driver's side door and continue driving. If the noise persists, it indicates the rear door is the source. Have a passenger in the back perform the same test to confirm which door is making the noise. Seal rubber or door lock noise: Cut newspaper into 10 cm wide strips and place them between the seal and the door contact surface. Close the door tightly and drive to test. If the noise disappears, it indicates the sound is caused by friction from the seal rubber. If the noise remains, the seal rubber can be ruled out. Generally, cars within 3 years of use experience seal rubber noise. Door lock noise: Wrap a layer of black insulating tape around the door lock striker. Close the door tightly and drive. If the noise disappears, it confirms that the noise is caused by friction between the door lock hook and the striker.

The Difference Between Motorcycle ABS and CBS

The difference between motorcycle ABS and CBS is that ABS prevents wheel lock-up, while CBS shortens braking distance; ABS has better safety performance than CBS; ABS is more expensive than CBS. ABS stands for Anti-lock Braking System. Its function is to automatically control the braking force during vehicle braking, preventing the wheels from locking up and maintaining a state of rolling and sliding, ensuring maximum adhesion between the wheels and the ground. CBS stands for Combined Braking System, which means the front and rear wheels of the motorcycle can be braked together. Braking both wheels simultaneously ensures maximum friction between the tires and the ground, allowing the motorcycle to achieve the shortest braking distance. The ABS braking system can prevent wheel lock-up, so vehicles equipped with ABS are less likely to skid or lose control during emergency braking, offering higher safety performance. The CBS system can also prevent loss of control to some extent, but its main function is to shorten the braking distance. Therefore, vehicles equipped with CBS have lower safety performance compared to those with ABS. Typically, vehicles equipped with ABS are high-end models and are more expensive, while those equipped with CBS are usually mid-to-low-end models and are slightly cheaper.

Is it dangerous to keep a fire extinguisher in the car during high summer temperatures?

Whether it is dangerous to keep a fire extinguisher in the car during high summer temperatures depends on local temperature conditions and maintenance. Generally, it will not explode. There are many types of fire extinguishers, and most vehicle-mounted fire extinguishers are dry powder extinguishers. Theoretically, dry powder extinguishers can be stored at temperatures between -20°C and 55°C, so they will not explode when kept in a car under normal conditions. Here are some items you should avoid leaving in the car during summer: Lighters: Small and easy to forget, yet highly dangerous. They contain liquid butane, and exposure to sunlight can increase internal pressure, leading to explosions. Bottled water: If left in a sun-exposed car for a certain period, it can release harmful substances. Continued consumption may not only fail to quench thirst but also affect health and cause discomfort. Glasses: Especially reading glasses, as their convex lenses can focus sunlight, potentially causing a fire. Perfume (in glass bottles): Perfume emits flammable gases when it evaporates. The critical packaging point is 49°C. Tests show that on a summer noon, without any shade, the car temperature can reach 65°C in just 15 minutes of sunlight exposure, which can easily trigger an explosion.

What Causes the Air Conditioner to Make Loud Noises When Turned On in a Car?

There are several reasons why the engine noise becomes louder when the car's air conditioner is turned on: Air conditioning pump noise: If there is an issue with either the electromagnetic clutch or the bearings inside the air conditioning pump, it can cause the pump to produce abnormal noises. Throttle valve clogging or sticking: If the throttle valve has carbon buildup or is sticking, it can lead to engine shaking and abnormal noises. Reasons for no air flow from the car's air conditioner: Blower fan malfunction: The car's blower fan is a crucial component for air flow from the air conditioner. If the air conditioning compressor fails during operation, the air conditioner will not produce air. Clogged air filter: The air filter is a significant and common reason for no air flow from the air conditioner. During operation, the car's air conditioner can accumulate many impurities from the air. Control system failure: This could be due to issues with the air vent, air conditioning computer, or control switch. Control system switches generally do not fail, and it is recommended that the owner visit a 4S shop for inspection to simplify the troubleshooting process.

What types of vehicles can a B2 license drive?

A B2 driver's license allows the holder to operate heavy-duty, medium-duty cargo trucks or large, heavy, and medium-sized specialized operation vehicles. Heavy-duty and medium-duty cargo trucks are primarily trucks. The vehicles permitted under a B2 license also include all vehicle types allowed by C1, C2, C3, C4, and M licenses, which include small and micro passenger vehicles, three-wheeled vehicles, wheeled self-propelled machinery, and light, small, and micro steering operation vehicles. With a B2 license, one is permitted to drive blue-plate minibuses with 9 seats or fewer and a vehicle length under 6 meters. Among these, heavy-duty and medium-duty cargo trucks are mainly trucks, such as the large trucks commonly seen on roads carrying construction debris, which fall under the category of heavy-duty trucks. Large, heavy, and medium-sized specialized operation vehicles refer to vehicles equipped with special devices or equipment, such as sprinkler trucks, concrete mixer trucks, fire trucks, etc. Among the heavy and medium-duty cargo trucks permitted under a B2 license, there are no restrictions on tonnage or length, but they must be trucks with the cargo compartment and storage on the same chassis. Some trucks where the cab can detach from the trailer are classified as tractors, commonly known as semi-trucks, and these types of trucks can only be driven with an A2 license.
