What type of fuel should a motorcycle use?

Generally, motorcycles use 92-octane gasoline, but 95-octane gasoline can also be used. Below is relevant information about gasoline: 1. Octane Rating: Different grades of gasoline have different octane ratings. The higher the grade, the higher the octane rating. Gasoline with a higher octane rating also has better anti-knock properties. Motorcycle engines with relatively high compression ratios generally require the use of 95-octane gasoline to prevent engine knocking. 2. Knocking Phenomenon: Knocking is an abnormal combustion phenomenon in the engine. A four-stroke gasoline engine has a compression stroke. After the compression stroke ends, the spark plug should ignite the combustible mixture, allowing it to burn and generate power to push the piston downward. Knocking occurs when the combustible mixture ignites on its own before the spark plug fires. At this point, the piston is moving upward, and the burning mixture pushes it downward, which can affect the engine's power output and even damage the engine. Severe knocking can even cause piston cracking or connecting rod deformation.

Can a car charge the battery while idling in place?

When a car is idling in place after starting, it can charge the battery. However, the electricity charged in this way is commonly referred to as "floating charge," which exists for a short period and will dissipate if the car is parked for a slightly longer time. If the battery charging indicator on the dashboard is not lit, it means the car is charging. If it stays lit, it indicates a charging fault, and the car should be taken to a repair shop for inspection. Below is an introduction to charging while idling: Operating principle of charging: Essentially, the engine drives the alternator (generator) to generate electricity, which is then rectified and stabilized to provide a certain voltage to the battery. Most of the time, this voltage is slightly higher than the battery voltage (e.g., 14V, while a normal battery is typically 12V), achieving constant voltage charging. Introduction to idling in place: Idling in place refers to a condition where the engine is running but the car is not moving, with the gear in neutral. This is often described as "working without output," consuming fuel without moving the car. The charging duration can also be affected by other factors, such as whether high-power devices are being used in the car, whether the air conditioning is on, or whether external USB power is being supplied. These factors can all increase the charging time.

Are the tires at 4S stores all original factory tires?

4S stores use original factory tires because all replacement parts at 4S stores need to be covered by warranty. Using original factory tires can to some extent enhance structural and performance guarantees. The parts used by 4S stores are directly supplied by manufacturers. If you go to an authorized 4S store for replacement, the tires will be identical to the original ones with no difference. During replacement, you can check the part number to verify if it's an original factory part. Advantages of using original factory tires: High compatibility with the vehicle: Original tires (parts) designed specifically for each vehicle model ensure the same technical condition and quality as new car parts, maintaining the vehicle's premium performance. Quality assurance: Every original tire (part) used by 4S stores is quality-certified by the automaker, ensuring reliable operation. Long warranty period: For genuine parts replaced at the customer's expense, replaced free of charge, or replaced free of charge due to recall repairs outside the vehicle warranty period (excluding vulnerable parts specified in the home vehicle three-proof certificate), the quality warranty period is 1 year or 20,000 kilometers. Whichever comes first between time and mileage applies.

What are the precautions for buying a car in full payment at a 4S store?

Precautions for buying a car in full payment at a 4S store include determining the ex-factory price, being cautious with free gifts, verifying the chassis number upon pickup, and inspecting the engine compartment. Determine the ex-factory price: When buying a car in full payment, consumers need to understand the ex-factory price. Generally, 4S stores do not force buyers to purchase insurance or other fees when paying in full, so consumers should negotiate based on the ex-factory price. Be cautious with free gifts: During price negotiations, 4S store salespeople may offer free gifts, which are usually inexpensive. If possible, consumers can request the value of the gifts to be deducted from the ex-factory price, making a price reduction more beneficial. Verify the chassis number upon pickup: When picking up the car, ensure the chassis number matches the code on the certificate of conformity. Check the production date of the car; a reasonable range is 3-6 months. Cars older than one year are not recommended for purchase. Inspect the engine compartment: Open the hood to check if the engine compartment is clean. Start the car for a few minutes, pull out the oil dipstick to check if the oil level and condition are normal, and inspect for any oil stains under the engine compartment.

Can the Car Film Provided by 4S Stores Be Used?

If it is some low-quality car film, it is better not to use it. If it is a product from a reputable brand with good quality, it can be used. Nowadays, many 4S stores offer gifts to customers after purchasing a car, such as floor mats, car films, and some car electronics. It is essential to carefully check whether the floor mats, films, and other products provided by the 4S store are high-quality and compliant. If they are inferior products, it is better not to install them in the car. Inferior films and floor mats can release toxic substances, affecting the health of passengers. Moreover, poor-quality films can significantly compromise driving safety, as their light transmittance does not meet standards, which can be hazardous during night driving. Inferior films also fail to block UV rays and provide heat insulation, accelerating the aging of the car's interior when parked under direct sunlight. It is recommended to purchase a high-quality film from a reputable brand after buying a car. Good-quality films can provide heat insulation and UV protection, safeguarding the car's interior. Additionally, premium films last longer and do not release harmful substances. High-quality car films have excellent light transmittance, ensuring safe night driving. When applying the film, it is advisable not to install it on the front windshield, as the windshield already has UV protection, and applying film there can impair driving visibility.

What kind of engine oil is usually used for the first free maintenance at a 4S dealership?

For the first free maintenance at a car 4S dealership, original equipment manufacturer (OEM) engine oil is typically used. In fact, OEM engine oil is produced by oil manufacturers according to the requirements of the car manufacturers. The first maintenance period for a new car is usually determined by either the mileage or the specified time interval, whichever comes first. Therefore, if the time interval is reached but the mileage is insufficient, the first maintenance should still be performed. Otherwise, the 4S dealership may claim that the standard has not been met, resulting in the information not being recorded in the nationwide warranty system, leading to the loss of warranty coverage. Precautions for the first car maintenance: In addition to changing the engine oil and oil filter, the first maintenance includes a comprehensive inspection and diagnosis of the vehicle's condition and usage. Typically, the first maintenance items are free of charge. If the technician recommends services not included in the first maintenance, the car owner should inquire whether there will be additional charges before deciding whether to proceed. As long as the new car undergoes its first maintenance at the 4S dealership within the specified period, it will still be eligible for the three-guarantee service even if subsequent maintenance is performed elsewhere. However, if the new car owner fails to have the first maintenance performed at the designated 4S dealership or the manufacturer's authorized service station within the specified mileage, any issues that arise with the car, even within the warranty period, may require the owner to pay certain repair costs.
