What Causes the Hissing Sound When a Car Goes Over Speed Bumps?

When a car goes over speed bumps and makes a hissing sound, it is the sound produced by the car's shock absorbers. Here is a detailed introduction to car shock absorbers: 1. Introduction: The most common type of shock absorber in household cars is the twin-tube shock absorber. What you see from the outside is the outer tube of the shock absorber, which contains an internal structure of pistons and piston tubes. The piston has valves, and the space between the piston and the piston tube, as well as between the piston and the outer tube, is filled with shock absorber oil. When the shock absorber is compressed, the piston squeezes the shock absorber oil, causing some of the oil to flow through the valves into the upper part of the piston, while another portion flows into the outer tube of the shock absorber. 2. Reason for the Sound: When the shock absorber rebounds, the piston moves upward, and the shock absorber oil in the outer tube flows back into the piston tube. At the same time, the oil in the upper part of the piston moves downward. The damping force is generated by the resistance of the shock absorber oil, which dissipates the impact force. Therefore, when the shock absorber is compressed or rebounds, the internal shock absorber oil flows rapidly, producing a 'puff' sound.

How to Remove Adhesive from Car Body?

Methods for removing adhesive from car body are as follows: 1. Hand Cream: Apply hand cream to the adhesive area, you can directly use your fingers to rub in a circular motion to avoid damaging the car paint. Wait until the adhesive shows obvious signs of loosening, then gently wipe with a damp cloth. 2. Alcohol: Alcohol has strong cleaning properties, and medical alcohol itself can be used to clean the skin. Dip a soft cloth into alcohol and gently wipe the adhesive area, the adhesive will easily soften and come off. Generally, alcohol does not cause any damage to plastic parts or the car paint surface. 3. Hair Dryer: For stickers or decals stuck on the car, the best way to remove them is to heat them first. Use a hot towel or a hair dryer to heat the sticker, then it can be easily peeled off. If there is residual adhesive, you can use products like essential balm or alcohol to wipe it off. Note that if the car window glass has a film, it is best not to use a hair dryer to heat it, as the film may bubble or peel off. 4. Adhesive Tape: Use high-quality transparent tape to stick on the residual adhesive. This method is generally effective for fresh adhesive stains, but for long-standing adhesive stains that have strongly bonded with the car body, the effect may not be very noticeable.

Is it necessary to rotate the front and rear tires of a sedan?

It is necessary to rotate the front and rear tires of a car. To achieve optimal tire wear, tire rotation is essential. The reasons for rotation are as follows: 1. Rotating the front and rear tires helps prevent uneven wear over time, extending the overall lifespan of the tires and ensuring driving safety. 2. This is particularly relevant for models with less precise chassis data. For vehicles with highly accurate chassis alignment data, rotating the front and rear tires can have drawbacks, primarily affecting the chassis data and causing the vehicle to pull to one side.

What is the fuel tank capacity of the 2020 Magotan?

The fuel tank capacity of the 2020 Magotan is 66 liters, which is the officially announced data. Owners who have purchased the 2020 Magotan can also check this information on the vehicle's configuration sheet. The recommended fuel grade for the 2020 Magotan is 95 octane, with a fuel consumption of 7.2-9.1L per 100 kilometers. A full tank of fuel can cover a distance of 725-916 kilometers. During daily driving, it is necessary to pay attention to the remaining fuel level in the tank at all times. Generally, the fuel level is observed through the fuel gauge inside the vehicle. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge typically has 5 to 6 segments, and it is advisable to refuel when there are only 2 segments left to avoid running out of fuel midway. During actual refueling, the amount of fuel may exceed the marked capacity. This is because the fuel tank capacity marked by the manufacturer is the volume from the bottom of the tank to the safe limit, and there is still some space from the safe limit to the tank opening. This space is reserved to allow for fuel expansion when the temperature rises, preventing overflow from the tank. If fuel is filled up to the tank opening during refueling, the actual refueling amount may exceed the marked fuel tank capacity.

What does a white line parking space mean?

White parking space: Indicates that this parking space is a paid parking space. In areas with white markings, roadside signs should be checked to determine whether parking is actually allowed here, as not all white lines on the roadside indicate parking spaces. Even in paid parking zones, parking is not allowed at all times; it must be done according to the instructions on roadside signs. Below are related explanations: 1. Blue parking space: Indicates that this parking space is a free parking space. However, it should be noted that there are two situations where penalties may apply: first, parking for more than one day or longer, as blue parking spaces prohibit malicious long-term occupation by motor vehicles; second, some blue dashed parking spaces may have time-limited parking indicated, and exceeding the time limit should be avoided. Additionally, some blue line parking spaces may have arrows indicating the parking direction, which should also be noted. 2. Yellow parking space: Indicates that this parking space is an exclusive parking space. Exclusive parking spaces are generally reserved for special vehicles, such as fire trucks. If the yellow line is a solid line, it means "no parking," and parking is not allowed in areas marked with a single solid yellow line or yellow curb. If the yellow line is dashed, it indicates that temporary parking is allowed, but long-term parking is not permitted.

How to Compensate for Low-End Torque Loss Due to Exhaust?

Currently, the popular valve exhaust system is a straightforward solution. It involves installing an adjustable valve in the exhaust pipe to control exhaust backpressure by opening or closing the valve, thereby compensating for low-end torque loss. Additional Information: 1. Passive Valve: A passive valve does not require an additional power source to operate and is typically installed inside the muffler or on the connecting pipe between the mid and rear sections. It mainly consists of a spring and a flap. When the engine speed is low, the exhaust flow is insufficient to overcome the spring tension and lift the flap, causing the exhaust pipe to be blocked by the flap, thereby increasing backpressure. At high engine speeds, the exhaust flow is strong enough to lift the flap, fully opening the exhaust pipe and reducing backpressure, ensuring optimal engine power output. 2. Active Valve: An active valve requires an additional power source to operate and is usually installed on the tailpipe. Depending on the driving mechanism, it can be categorized as either an electric valve or a pneumatic valve. The electric valve is driven by a motor, while the pneumatic valve is driven by a vacuum pump. Similar to the passive valve, the active valve closes at low engine speeds to increase backpressure and opens at high speeds to reduce backpressure. Compared to passive valves, active valves provide lower backpressure at high speeds because the energy to open the valve is supplied by the battery, avoiding engine power loss. In contrast, passive valves require a small amount of engine power to overcome the spring tension, though this energy consumption is negligible.
