ACEA-C3 and C5 refer to the testing and certification standards for automotive lubricants established by the European automobile manufacturing industry, with ACEA-C5 being the highest level in this series of standards. The details are as follows: 1. The AECA-C3 standard is higher than the API standard: AECA-C3 oil is a top-tier low SAPS1 lubricant, primarily used for high-performance gasoline and light-duty diesel engines equipped with diesel particulate filters (DPF) and three-way catalysts (TWC). These engines employ advanced after-treatment systems. 2. The ACEA-C5 standard is higher than C3: However, the oil quality under both standards is stable and maintains its grade over time. ACEA-C5 oil can also be used in high-performance gasoline and light-duty diesel engines equipped with DPF and TWC. For example, Kunlun Lubricant's 0W20 model meets the ACEA-C5 standard, emphasizing better fuel economy.

How many kilometers can a Honda Vezel run on a full tank of gas?

Vezel can run 500-600 kilometers on a full tank of gas. The size of the fuel tank is directly related to the vehicle's fuel consumption, generally allowing a range of over 500 kilometers per tank. Definition of fuel tank capacity: Its capacity measures a vehicle's ability to carry fuel. A larger fuel tank can hold more fuel, providing longer endurance and greater range, reducing the frequency of refueling. With a larger tank, in areas with sparse gas stations, the vehicle can reach more distant stations when running low on fuel, avoiding the risk of running out of gas and stalling. Relationship between fuel tank and fuel consumption: The size of the fuel tank is directly related to the vehicle's fuel consumption. Generally, a full tank can cover over 500 kilometers. For example, a vehicle consuming 10 liters per 100 kilometers typically has a fuel tank capacity of around 60 liters.

What are the symptoms of a damaged hydraulic valve lifter?

Damage to the hydraulic valve lifter can result in insufficient cylinder pressure due to the hydraulic valve pushrod. Below are specific details about hydraulic lifters: 1. Replacement precautions: Hydraulic lifters are not interchangeable; when replacement is necessary, a complete set should be replaced. During assembly, the lifter surface should be coated with engine oil. After installing new hydraulic lifters, do not start the engine immediately within 30 minutes, and initial noise upon engine startup is normal. 2. Working principle: When the camshaft rotates to the working surface, the hydraulic lifter housing and support rise. At this point, the one-way valve is closed, preventing oil from escaping. Due to the incompressibility of the oil, the lifter acts as a solid unit, pushing the valve open against the spring tension. When the camshaft moves past the working surface, the pressure in the high-pressure chamber decreases, allowing the oil to push open the one-way valve again and refill the high-pressure chamber, repeating the cycle.

Can I park in a parking space with arrows on the ground?

Parking spaces with arrows on the ground can be used for parking. Drivers must not only park within the designated space and lines but also follow the direction indicated by the arrows. There are three types of parking space markings: white lines indicate paid parking spaces, yellow lines indicate reserved parking spaces, and blue lines indicate free parking spaces. Below are the details: White line parking spaces: These parking spaces are marked with white lines, indicating they are paid parking spaces. They are usually located on sidewalks or setback lines and are managed by parking fee collection companies. Yellow line parking spaces: These parking spaces are marked with yellow lines, indicating they are exclusive parking spaces. They are typically leased or set up by relevant authorities for office use or to facilitate public parking. Blue line parking spaces: These parking spaces are marked with blue lines, indicating they are free parking spaces. They are usually planned around government office areas.

Is it necessary to use a circulation machine for transmission fluid replacement?

Whether it is necessary to use a circulation machine for transmission fluid replacement depends on specific circumstances. Here is a detailed introduction to circulation machine fluid replacement: 1. Fluid replacement method: The circulation machine injects new fluid while extracting the mixed old and new fluid, resulting in a high replacement rate and more thorough fluid replacement. However, it consumes more fluid, is relatively wasteful, and incurs higher costs. 2. Reasons not to recommend using a circulation machine: It is not recommended to use a circulation machine for transmission fluid replacement, especially for automatic transmissions with high mileage, due to certain risks. While the circulation machine can remove impurities stuck in the torque converter, hydraulic valve body module oil passages, or deposited in the oil pan and transmission filter, these impurities may flow through the pipes and clog components such as the torque converter, hydraulic valve body, and transmission filter screen. This can lead to issues like poor oil flow and solenoid valve sticking. Therefore, the appropriate fluid replacement method should be chosen based on the vehicle's specific usage conditions and transmission model.

What is the reason for low tire pressure in one tire of a new car?

A new car having low tire pressure in one tire is caused by poor sealing performance of the tire. Here is a detailed introduction to adjusting car tire pressure: 1. Rough roads: On rough roads, it is appropriate to reduce the tire pressure by 0.1-0.2bar below the standard tire pressure. For long-distance high-speed driving, the tire pressure should not be too low; it is advisable to increase the tire pressure by about 0.2bar above the lower limit of the standard tire pressure. 2. New vs. old tires: For new tires, the tire pressure can be increased by about 0.2bar above the standard tire pressure. For old tires, it is appropriate to reduce the tire pressure according to the standard tire pressure, and if the wear is severe, follow the lower limit of the standard tire pressure. 3. Summer and winter: In winter, it is advisable to increase the tire pressure by about 0.2bar above the standard tire pressure. In summer, follow the lower limit of the standard tire pressure. If the car is parked outdoors in summer, the tire pressure can generally be about 0.1bar lower than the standard to avoid high-temperature blowouts.

Can a motorcycle still be registered if the QR code on the certificate of conformity cannot be scanned?

If the QR code on the motorcycle's certificate of conformity cannot be scanned, the motorcycle cannot be registered, and the certificate of conformity needs to be replaced. New motorcycle registration process: Before applying for a license plate, you should first bring the invoice, certificate of conformity, and your ID card to the National Tax Bureau to apply for the vehicle purchase tax, and then go to an insurance company to apply for compulsory third-party liability insurance for the motorcycle. After completing the above procedures, you can go to the vehicle management office of the traffic police brigade of the public security bureau to apply for the license plate. If all the documents are complete, the process can be completed in one go. When applying for registration, the owner of the motor vehicle should fill out an application form, present the motor vehicle for inspection, and submit the following documents and certificates: The identity document of the motor vehicle owner, the invoice or other proof of the origin of the motor vehicle, the certificate of conformity for the whole vehicle or the import certificate for imported motor vehicles, the tax payment or exemption certificate for vehicle purchase tax, the certificate of compulsory third-party liability insurance for motor vehicle accidents, and the tax payment or exemption certificate for vehicle and vessel tax.
