What type of engine oil should be used for Yunnei engines?

How to Determine Vehicle Emission Standards?

There are several methods to check vehicle emission standards: 1. Vehicle environmental protection label: The simplest and most direct way is to look at the vehicle's environmental protection label, which has clear markings on the back. 2. Professional query websites: Visit professional query websites for verification. You can search for the keyword "motor vehicle environmental protection" on Baidu to find relevant websites where you can input vehicle information for checking. 3. Vehicle manufacturing certificate: For new cars, you can refer to the vehicle manufacturing certificate and look for the information inside. However, generally, the certificate is kept at the vehicle management office. Therefore, it is advisable to make a copy for your records when purchasing a new car. 4. Environmental protection window at the vehicle management office: Bring the vehicle's registration certificate to the environmental protection window at the vehicle management office or the local motor vehicle pollution management center, where staff can assist in checking the information.

How Often Should Motorcycle Oil Be Changed?

New motorcycles require an oil change every 1,000 kilometers initially, followed by every 3,000 kilometers thereafter. Below is an introduction to the functions of engine oil: The Lubrication Function of Engine Oil: There is rapid relative sliding between the piston and cylinder, as well as between the main shaft and bearing bush. To prevent excessive wear on components, an oil film must be established between the two sliding surfaces. A sufficiently thick oil film separates the surfaces of the relatively sliding parts, thereby reducing wear. The Auxiliary Cooling Function of Engine Oil: Due to its relatively low specific heat value and its location inside the engine, engine oil does not inherently have a cooling effect. However, as fuel combustion generates heat within the engine during operation, the engine oil carries this heat back to the oil tank, where it is then dissipated into the air, assisting the radiator in cooling the engine. The actual cooling effect is provided by the water outside the engine casing.

What are the differences between hybrid and range-extended electric vehicles?

The difference between hybrid and range-extended electric vehicles is that the engine in a range-extended vehicle only supplies power and does not drive the wheels. Hybrid vehicles have a transmission and are driven by the engine. Range-extended electric vehicle system: The system is equipped with an internal combustion range extender on the vehicle, which is solely responsible for generating electricity for the vehicle. The generated electricity not only directly powers the drive motor but also charges the battery. When the battery is sufficiently charged, the internal combustion engine can stop working, and the battery directly powers the motor to propel the vehicle forward. Hybrid electric vehicle system: It consists of two power systems: motor drive and engine drive. A plug-in hybrid is a hybrid vehicle that can be charged externally, serving as a "fuel-efficient version" of a gasoline-powered car to some extent, capable of both charging and refueling.

How is the route selection for Subject Three conducted?

Subject Three route selection varies depending on the situation, as driving school systems differ across regions. The specific method of selection is determined locally. Different scenarios for route selection: Some driving schools conduct the selection on the exam day. After candidates arrive at the test center, submit their exam files, and enter the waiting room, the exam route is randomly selected by a computer. The result will be displayed on the screen along with the candidate's exam information. Additionally, for some driving schools, the Subject Three exam route is selected by the instructor on the exam day, and candidates only learn the route after boarding the vehicle. The exact method depends on the local practice, and candidates can inquire with their instructors or driving schools. Important notes: If fingerprint verification fails, candidates must exit the vehicle to re-collect their fingerprints before rejoining the queue for the exam. During the exam, if a candidate's score falls below the passing threshold, the system will automatically prompt the candidate to pull over. After completing the pull-over maneuver, the system will indicate the start of the next exam attempt.

How to Tell What Year a Car Is?

Here are the methods to determine the year of a car: 1. Check the manual: If you want to know the model year of the car, the most direct method is to look at the manual provided at the time of purchase, as it will include this information. 2. Look at the vehicle's nameplate: You can also check the car's nameplate, which is usually located below the passenger-side door and can be seen when the door is opened. 3. Call customer service: There is always a dedicated customer service representative you can contact for inquiries. If you have any questions about the car, you can directly ask the customer service. 4. Check the car's VIN code: Generally, the 10th digit of the car's VIN code indicates the year. However, this year may differ slightly from the manufacturing year, usually by no more than a year, and is close to the model year, which is generally the default assumption.

What to Do When the Vehicle Battery is Low on Power?

When the vehicle battery is low on power, charge it promptly. Reasons for low battery power: Car battery failure, leaving lights or radio on for an extended period while the engine is off. When parking for a long time, it is also advisable to turn off the power of unnecessary electrical devices (such as interior and exterior lights, audio systems, navigation, etc.). Solutions for a dead battery: Use the push-start method to assist in ignition. The principle of "push-starting" the car is to manually push the vehicle, converting this kinetic energy to the cylinder pistons, forcing the compression of gases inside the cylinder and igniting them. After successful ignition, do not turn off the engine immediately; maintain idle speed for a while to charge the battery.
