Suspension refers to all the force-transmitting connection devices between the vehicle frame and axle. Its function is to transmit forces and torques acting between the wheels and frame, while cushioning the impacts from uneven road surfaces transmitted to the frame or body, thereby reducing resulting vibrations to ensure smooth vehicle operation. A typical suspension system consists of elastic elements, guiding mechanisms, and shock absorbers, with some structures additionally including bump stops and anti-roll bars. Elastic elements come in various forms such as leaf springs, air springs, coil springs, and torsion bars. Modern passenger cars predominantly use coil springs and torsion bars, while some premium vehicles employ air springs.

What are the methods to remove odors from cars?

There are mainly three methods to remove odors from cars. Below is a detailed introduction to these three methods: 1. Ventilation: The best way to remove formaldehyde from a new car is to frequently open the windows for ventilation. Try to keep the windows open while driving. When using the air conditioner with windows closed, switch to the external circulation mode to maintain air flow inside the car, which helps eliminate odors and formaldehyde from the car's air. 2. Bamboo charcoal bags: The bamboo charcoal in these bags has a porous structure with strong adsorption capabilities, enabling it to absorb harmful gases such as formaldehyde, benzene, and sulfur dioxide inside the car, while also releasing natural minerals. Additionally, bamboo charcoal bags are highly absorbent, providing dehumidification, deodorization, and anti-mold benefits for the car interior. 3. Car air purifiers: These devices can filter the air inside the car, effectively removing not only formaldehyde but also other air pollutants like PM2.5, TVOC, odors, bacteria, and viruses with significant results.

Can Mobil Really Last 18,000 Kilometers?

Mobil can indeed last up to 18,000 kilometers, but this depends on the condition of the vehicle and the road conditions. The same oil will perform differently in new and old vehicles. Therefore, the best oil is the one that suits your vehicle, which naturally allows for longer mileage. Below are the functions of engine oil: 1. Friction Reduction: A sufficiently thick oil film separates the surfaces of relatively sliding parts, thereby reducing wear. 2. Sealing: Engine oil can form a seal between the piston rings and the piston, reducing gas leakage and preventing external contaminants from entering. 3. Rust Prevention: Lubricating oil adheres to the surface of parts, preventing contact with water, air, acidic substances, and harmful gases. 4. Cushioning: When the pressure at the engine cylinder port rises sharply, suddenly increasing the load on the piston, piston skirt, connecting rod, and crankshaft bearings, this load is transmitted and lubricated through the bearings, cushioning the impact load. 5. Cleaning: High-quality engine oil can carry carbon deposits, sludge, and worn metal particles from engine parts back to the oil tank through circulation, washing away dirt generated on the working surfaces of the parts through the flow of the lubricating oil.

How to Make a Right Turn at an Intersection?

Three priority principles: yield to vehicles going straight, yield to vehicles coming from the right, and right-turning vehicles yield to left-turning vehicles. This includes the road driving skills test and the safe and civilized driving knowledge test, which are part of the motor vehicle driver's license assessment. These tests are collectively referred to as the road driving skills and safe and civilized driving knowledge test subjects in the motor vehicle driver's examination. The content of the road driving skills test varies depending on the type of vehicle being licensed. Below is an introduction to the content of other examination subjects: 1. Subject 1: Also known as the Subject 1 theory test or driver theory test, it is part of the motor vehicle driver's license assessment. The test content includes driving theory basics, road safety laws and regulations, local regulations, and other related knowledge. The test format is computer-based, with 100 questions, and a passing score of 90 or above. 2. Subject 2: Also known as the small road test, it is part of the motor vehicle driver's license assessment and is the abbreviation for the field driving skills test subject. For small vehicles C1 and C2, the test items include reversing into a parking space, parallel parking, stopping and starting on a slope, turning at a right angle, and driving through curves (commonly known as the S-curve), which are the five mandatory test items. 3. Subject 4: Also known as the Subject 4 theory test or driver theory test, it is part of the motor vehicle driver's license assessment. The Subject 3 test is divided into two parts: in addition to the road test, a safe and civilized driving knowledge test has been added, commonly referred to as 'Subject 4,' which assesses 'driving ethics.' The test paper consists of 50 questions, with questions presented in the form of case studies, pictures, animations, etc. The maximum score is 100, and a score of 90 is required to pass.

What does it mean when the ABS light comes on in a semi-trailer?

Semi-trailer ABS light on means that the vehicle's anti-lock braking system is faulty. During emergency braking, if the wheels lock up, the vehicle will lose control and skid, making it impossible for the driver to slow down or adjust the vehicle's trajectory, posing a significant safety hazard. The reasons for the ABS light coming on in a semi-trailer are as follows: ABS speed sensor sensing part is covered: The ABS speed sensor sensing part is covered by mud, sludge, or other contaminants, affecting the sensor's ability to detect the corresponding speed signal. This prevents the ABS computer from determining the vehicle speed and the wheel slip rate, and thus cannot issue the appropriate commands to adjust the braking. Solution: Clean the dirt on the speed sensor and adjust the gap between the speed sensor and the signal ring to restore normal operation. Poor ABS signal: Due to loose connections between system lines or poor contact of the ABS relay, the signal quality is compromised, leading to system failure. The most common issue is a loose speed sensor wire connection, which will also show as a poor speed sensor signal in the ABS computer's fault memory. Solution: Check the line connections and reconnect any loose parts.
