What does 98W on a tire represent?

98 is the load index of the tire, indicating a maximum load capacity of 750KG per tire. W represents the speed rating, which denotes the maximum speed the tire can sustain under specified conditions with a given load. The W speed rating corresponds to a maximum speed of 270 kilometers per hour. Tires are one of the most critical components of a vehicle, serving several key functions: 1. Supporting the entire weight of the vehicle, bearing the load, and transmitting forces and moments in other directions; 2. Transmitting traction and braking torque to ensure good adhesion between the wheel and the road surface, thereby improving the vehicle's power, braking, and off-road performance; working in conjunction with the suspension system to absorb shocks during driving and dampen resulting vibrations; 3. Protecting vehicle components from severe vibrations and premature wear, adapting to high-speed performance while reducing driving noise, and ensuring safety, handling stability, comfort, and fuel efficiency.

What is the correct method for one-button start in a manual transmission car?

Manual transmission car one-button start steps are as follows: 1. After the driver sits in the driver's seat, press the start button once, at which point the ACC light will illuminate. Then press it once more, and the vehicle will perform a self-check. 2. Depress the brake pedal and press the one-button start key to ignite and start the engine. 3. Release the foot brake, and you may choose to warm up the car in place; the duration can be determined based on the environment. 4. Depress the foot brake again, shift to D gear, and release the handbrake (for electronic handbrakes, simply press the button briefly). 5. Slowly release the foot brake, apply the accelerator, and the start-up is complete. Manual transmission cars use manual MT, also known as manual gear, which requires manually moving the gear lever to change the gear meshing device inside the transmission, altering the gear ratio to achieve the purpose of shifting gears.

Does Engine Oil Have a Shelf Life?

Engine oil does have a shelf life. Unopened engine oil typically lasts 3-5 years, while opened engine oil has a shelf life of about 6 months. The following are the functions of engine oil: 1. Cleaning: The cleaning process is achieved through the circulation of oil within the engine; 2. Sealing: Oil forms a film in the gaps between components, which acts as a seal to ensure the tightness of the cylinders; 3. Cooling: During engine operation, a large amount of heat is generated. Most of this heat is dissipated through the engine's cooling system, while some is absorbed by the oil from surfaces like the cylinders and pistons, then carried to the oil pan for dissipation; 4. Anti-rust: Engine oil contains multi-functional additives like rust inhibitors, which form a dense, well-arranged protective layer on metal surfaces, effectively preventing the intrusion of corrosive substances. 5. Cushioning: During engine startup, acceleration, or significant load changes, components such as piston pins, connecting rod ends, and crankshaft bearings experience intense vibrations. Oil with appropriate viscosity can absorb some of the impact energy, providing a cushioning effect.

Can a 400cc Motorcycle Be Licensed?

Motorcycles are classified as motor vehicles and must be licensed. Below are the relevant regulations: 1. Article 13: Motor vehicle license plates must be displayed at designated positions on the front and rear of the vehicle, kept clear and intact. Heavy and medium-duty trucks and their trailers, as well as tractors and their trailers, must have enlarged license plate numbers painted on the rear of the body or carriage, with characters upright and clearly visible. The motor vehicle inspection compliance mark and insurance mark must be affixed to the upper right corner of the front window. Any painting, labeling, or body advertising on the motor vehicle must not affect safe driving. 2. Article 39: When driving at night under good street lighting or in poor visibility due to dim weather, motor vehicles must turn on anti-glare low beams, width indicators, and taillights; when driving at night without street lighting or with poor street lighting, low beams must be switched to high beams, but following vehicles in the same direction must not use high beams; fog lights must be turned on in foggy weather.

When will China VI emission standards be implemented?

China VI standards are divided into two phases, a and b. Starting from July 1, 2019 at the earliest, all light-duty vehicles sold and registered must comply with China VIa requirements; by July 1, 2023 at the latest, all light-duty vehicles sold and registered must meet China VIb limit requirements. This means that China VIa can only be considered a transitional phase, while China VIb represents the true China VI stage. More relevant information is as follows: 1. Currently, some regions have implemented China VI emission standards ahead of schedule. For example, Guangzhou implemented China VI emission standards for light-duty gasoline and diesel vehicles starting from March 1, 2019; Shenzhen required light-duty diesel vehicles to comply with China VI standards from July 1, 2018, and light-duty gasoline vehicles to meet China VI standards from July 1, 2019. 2. After the announcement of China VI standards, their extremely strict limit values earned them the title of "the most stringent standards in history." Compared to the current China V standards, China VI standards reduce carbon monoxide emissions by 50%, total hydrocarbon and non-methane hydrocarbon emission limits by 50%, and nitrogen oxide emissions by 42%. All indicators not only fully meet the current EU standards but even exceed them in some cases.

What Causes Car Tail Lights to Stay On?

Car tail lights staying on is due to a short circuit in the brake light switch, which requires replacement. If the issue is not with the brake light switch, it may be a fault in the car's electrical system. Owners should not attempt to fix this themselves and should instead seek professional help at a 4S store or a specialized repair shop. Brake lights are typically installed at the rear of the vehicle to enhance the penetration of the light source, making it easier for following vehicles to detect braking even in low visibility conditions, thereby helping to prevent rear-end collisions. Brake lights illuminate when the vehicle brakes and are usually red, effectively preventing rear-end collisions and reducing traffic accidents. They are bright and highly visible, primarily serving to alert following vehicles. Incorrect use or malfunction of brake lights can easily lead to rear-end collisions. Additionally, when replacing brake light bulbs, note that vehicle tail lights often serve dual purposes—each bulb contains two filaments: a weaker one for the parking light and a stronger one for the brake light. Some manufacturers design these as high-low pin plug-ins for convenience, but care must be taken during replacement to avoid incorrect installation.
