What Are the Hazards of Slamming Car Doors Too Hard?

The hazards of slamming car doors too hard are: 1. Deformation or detachment of the sealing strip; 2. Loosening of internal components leading to malfunction or abnormal noises; 3. Incomplete door closure, leaving a slight gap. Car doors provide access for drivers and passengers, isolate external disturbances, mitigate side impacts to some extent, and protect occupants. The design of car doors affects the vehicle's aesthetics, and their quality is primarily reflected in crash resistance, sealing performance, ease of opening and closing, and functional indicators. The crash resistance of car doors is particularly crucial, as the buffer distance is very short during side collisions, which can easily injure occupants.

Does gravel hitting the undercarriage affect the car?

Gravel hitting the undercarriage does affect the car. Here are the specific details: 1. Minor scratches: The impact is minimal. There is a layer of metal sheet under the car's undercarriage, which can be repaired and improved during the next maintenance or repair. 2. Severe impacts: It is necessary to stop and inspect the car, mainly checking whether the oil pan is cracked, whether the tie rod is deformed, and whether the brake lines are broken or damaged, as these directly affect driving safety. 3. Consequences: For small cars, undercarriage scrapes by stones often result in oil pan damage leading to oil leaks, while other issues are relatively less common. However, for your own safety, it is advisable to have it checked at the nearest repair shop.

What Causes the Zizzing Sound After Starting the Vehicle?

The zizzing sound after starting the vehicle is caused by an issue with the engine belt. The engine belt is the main belt in a car, connecting components such as the generator, air conditioning compressor, power steering pump, idler pulley, tensioner pulley, and crankshaft pulley. Its power source is the crankshaft pulley, which drives the other components to operate together. When small cracks appear on the contact surface between the belt and the pulley, replacement is necessary. The engine is the device that provides power to the car, acting as the heart of the vehicle and determining its power, fuel efficiency, stability, and environmental performance. Depending on the power source, car engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrid engines.

What is the difference between 72V 20Ah and 72V 32Ah?

The differences between 72V 20Ah and 72V 32Ah are as follows: 1. Current difference: Ah stands for ampere-hour. 20Ah means it can discharge at 20 amps continuously for one hour, while 32Ah means it can discharge at 32 amps continuously for one hour. In terms of current alone, 32Ah is significantly stronger than 20Ah. 2. Capacity difference: At the same voltage, the battery capacity of 20Ah is smaller than that of 32Ah. 3. Weight difference: The 20Ah battery appears larger in size compared to the 32Ah, but the 32Ah battery is heavier. 4. Range difference: With the same rated voltage, the 32Ah battery has a larger energy storage capacity, allowing it to travel a longer distance than the 20Ah battery, providing a greater riding range.
