SP is the new standard of the American Petroleum Institute, which is the grade standard for engine oil; C3 engine oil is the testing and certification standard for automotive lubricants by ACEA, the European Association of Automobile Manufacturers. The relevant information about engine oil is as follows: 1. Introduction: Engine oil, also known as engine lubricant, English name: Engine-oil. With a density of approximately 0.91×10³ (kg/m³), it can lubricate and reduce wear, assist in cooling, seal and prevent leaks, prevent rust and corrosion, and provide shock absorption for the engine. 2. Composition: Engine oil consists of two parts: base oil and additives. Base oil is the main component of lubricating oil, determining its basic properties, while additives can compensate for and improve the shortcomings of base oil performance, endowing it with new properties, making them an important part of lubricating oil.

What is the difference between the seizure and detention of a driver's license?

Here are the differences between the seizure and detention of a driver's license: 1. Difference: The detention of a motor vehicle driver's license refers to an administrative compulsory measure taken by traffic police during the execution of their duties. The temporary seizure of a motor vehicle driver's license refers to a penalty method by which the traffic management department of the public security authority lawfully suspends the motor vehicle driving qualification of a road traffic law violator for a certain period. 2. Detention of a motor vehicle driver's license: The main purpose of this administrative compulsory measure is to ascertain the facts of the road traffic violation committed by the party involved, in order to make a correct penalty decision. For example, traffic police may detain the motor vehicle driver's license of a road traffic law violator in cases such as driving under the influence of alcohol or drunk driving; driving a vehicle that is assembled or has reached the scrapping standard; or accumulating 12 points in a single scoring cycle, where it is deemed necessary to impose a penalty of temporary seizure or revocation of the motor vehicle driver's license. Before detaining the driver's license, the traffic police should verbally inform the party involved of the basic facts of the violation, the basis for the intended compulsory measure, and the rights the party is entitled to by law. After preparing the "Administrative Compulsory Measures Certificate" and delivering it to the party on the spot, the driver's license is lawfully detained. The detention period of the violator's driver's license lasts until the day the public security authority lawfully imposes an administrative penalty. 3. Temporary seizure of a motor vehicle driver's license: When imposing the penalty of temporary seizure of a motor vehicle driver's license on a driver, the driver's license should be transferred to the vehicle management office at the place of issuance within 15 days after the penalty decision is made. The driver's license should be returned according to the prescribed procedures after the temporary seizure period expires. This is equivalent to the suspension of the motor vehicle driver's license in the original "Road Traffic Management Regulations" and the original "Road Traffic Accident Handling Measures". After the public security authority implements the administrative compulsory measure of detaining the motor vehicle driver's license, it should investigate the illegal facts within the statutory time limit. If it is decided to impose the penalty of temporary seizure of the motor vehicle driver's license on the party involved, the decision should be made by the traffic management department of the public security authority at or above the county level.

How to Distinguish Between Dry and Wet Dual-Clutch Transmissions?

Methods to distinguish between dry and wet dual-clutch transmissions: The clutch plates in a dry dual-clutch transmission are not immersed in transmission oil, whereas those in a wet dual-clutch transmission are immersed in transmission oil. Dual-clutch transmissions offer fast gear shifting and high transmission efficiency. Dry dual-clutch transmissions shift quickly, but they have poor heat dissipation, average reliability and durability, and less smooth gear shifting. Wet dual-clutch transmissions, while not as fast in shifting as dry ones, provide better heat dissipation, smoother gear shifting, and superior reliability and durability compared to dry dual-clutch transmissions.

Why does the seat belt not retract?

Seat belt not retracting is due to accumulated dirt over prolonged use, which can cause the belt to stiffen and get stuck at the hook above the seat. Meaning of car seat belts: Car seat belts are the primary safety devices designed to protect adult passengers. In the event of a collision or sudden braking, they prevent the driver or passengers from secondary impacts with objects like the steering wheel or windshield, thereby reducing serious injuries. The function of seat belts: Seat belts secure the occupants to their seats, significantly reducing displacement during accidents and minimizing potential injuries.

Can an automatic transmission car start in L gear?

An automatic transmission car can start in L gear, but it is not practical in actual driving. The true purpose of the L gear is to use it when going uphill or downhill, preventing the vehicle from adjusting gears based on speed, which is a safer way to descend. When using the L gear, the vehicle's power will not be very strong. When descending a steep slope or climbing, the engine gear will be limited to L gear, and no matter how much the accelerator is pressed, the gear will not increase, making it very safe for uphill and downhill driving. However, it is not recommended to use the L gear during normal vehicle starts, as it consumes more fuel and is not suitable for regular driving.

Can Hybrid Vehicles Obtain New Energy License Plates?

Whether hybrid vehicles can obtain new energy license plates depends on the model type. Hybrid vehicles are divided into plug-in hybrids and range-extended hybrids. In China, plug-in hybrids are classified under the new energy vehicle catalog and can be issued green license plates. New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources, integrating advanced technologies in vehicle power control and driving, resulting in advanced technical principles, new technologies, and new structures. New energy vehicles include pure electric vehicles, range-extended electric vehicles, hybrid vehicles, and fuel cell electric vehicles. Special license plates for new energy vehicles are green with black characters and black borders, featuring a gradient green color, while large new energy vehicle license plates are a combination of yellow and green.
