What Causes the Abnormal Noise When Accelerating a Car?

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.

What Happens When a Car's Exhaust Pipe Leaks?

Leakage in a car's exhaust pipe can cause engine oil leakage. Here are some relevant extended details: 1. Consequences of the fault: The exhaust pipe can redirect exhaust gases from the engine back into the intake manifold, allowing these gases to enter the combustion chamber. Since exhaust gases cannot combust, their presence in the combustion chamber lowers the chamber's temperature and reduces the combustion rate. 2. General treatment: For an exhaust pipe leak, you can first try replacing the gasket, as the leak might be due to gasket aging. However, if replacing several gaskets doesn't resolve the issue, a thorough inspection is necessary. If the front section of the exhaust pipe's interface is found to be deformed with small pits or bumps, a repair method involving wrapping copper wire around the interface can be used to seal the leak and eliminate abnormal noises during engine operation.

Is It Dangerous to Keep Foam Glue in the Car?

Foam glue is a chemically reactive material, and keeping it in the car is quite dangerous. If exposed to intense sunlight, it may explode and can be very difficult to clean up. Below are some relevant details: 1. Function: Foam glue is categorized into two-component foam glue and single-component foam glue. After curing, it serves purposes such as bonding and sealing. During the curing process, it relies on moisture in the air to solidify, especially when stored, requiring proper sealing to prevent exposure to air, which would trigger curing. 2. Storage Requirements: When storing foam glue, it should be kept in a cool, ventilated place, avoiding direct sunlight. Prolonged exposure to sunlight can alter the properties of the glue. Even if it hasn't expired, its bonding and sealing effectiveness will be significantly reduced. The foam may also become uneven, with larger bubbles, greatly diminishing its waterproofing and insulating properties.
