The reasons for the fault light of Baojun 510 coming on include unqualified fuel quality, oxygen sensor failure, etc. The specific details are as follows: Unqualified automobile fuel quality: If the engine fault light on the car dashboard comes on shortly after refueling, it is generally due to incorrect or poor-quality fuel that does not meet standards, resulting in insufficient combustion of the air-fuel mixture during engine operation. Oxygen sensor failure: Currently, cars are generally equipped with two oxygen sensors, one before and one after the three-way catalytic converter. Their function is to detect the air-fuel ratio under different engine operating conditions. At the same time, the front one provides signals to the ECU for adjusting the fuel injection volume and calculating the ignition timing. The rear one is used to detect the working condition of the three-way catalytic converter.

What is the difference between driving experience and vehicle age?

Driving experience refers to the number of years a person has been driving, while vehicle age refers to the number of years a vehicle has been in use. Relevant information about driving experience is as follows: 1. Definition: Driving experience is the number of years since a motor vehicle driver obtained their driving qualification, calculated from the date the driver obtained their driving qualification. If a driver obtains different driving qualifications by adding permitted vehicle types (additional driving qualifications), each qualification has its own separate driving experience, which should not be confused. 2. Calculation method: According to the relevant provisions of the "Regulations on the Application and Use of Motor Vehicle Driving Licenses" (Ministry of Public Security Order No. 123), if a driving license is revoked due to failure to renew it on time or failure to submit a medical examination certificate for no more than two years, the driver can restore their driving qualification by passing the subject one exam (road traffic safety laws, regulations, and related knowledge test). After restoring the driving qualification, the original permitted vehicle types of the driving license are retained, and the driver's original driving experience is calculated continuously. If the driving license is revoked due to failure to renew it on time or submit a medical examination certificate for more than two years, or if the driving license is revoked due to the driving license being legally revoked or the driving permit being legally canceled, the driver needs to reapply for a motor vehicle driving license from the vehicle management office of the public security traffic management department, and the driving experience is recalculated as for the first-time application.

What is compatible with 80/90-12 tires?

80/90-12 model tires can be interchanged with 80/100-12, 90/90-12, 3.0-12, 90/70-12, etc. 80/90 and 90/90 refer to the width of the tire. The number 12 indicates the tire diameter. As long as the tire diameter is the same, a slightly wider or narrower tire will not affect normal driving. Additional information: The 80/90-12 tire has a width of 80 millimeters, approximately equal to 3.15 inches, which falls between 3.00 inches and 3.25 inches. Therefore, choosing a 3.00-12 or 3.25-12 tire is more appropriate—the former is slightly narrower than the original, while the latter is slightly wider. It is recommended to use 3.25-12.

Does a Flush Machine Oil Change Require Filter Replacement?

The concept of replacing the filter applies only to engine oil changes. However, engine oil changes do not require the use of a flush machine. Only transmission fluid involves replacement via a flush machine, but transmission fluid does not have a filter at all. Additional information: Here are details on automotive transmission fluid replacement: 1. The replacement interval for automatic transmission fluid is every 2 years or 40,000 kilometers. 2. Due to the highly precise internal structure of automatic transmissions and the high cost of repairs, coupled with the fact that the commonly used gravity drain method cannot fully replace the fluid, it is crucial not to delay automatic transmission fluid changes to avoid greater losses. 3. The transmission fluid replacement points are located on the transmission housing with two bolts: the upper bolt serves as the fill port, and the lower bolt is the drain port.

According to the "Road Traffic Safety Violation Scoring Management Measures," the driver's license scoring cycle is as follows: If a driver commits a traffic violation that requires point deduction, the points will be added to the driver's license starting from 0, not deducted from 12. From the date of the first issuance of the license, the points on the driver's license are 0. When checking the driver's license point deduction records, the lower the score, the better. If 12 points are deducted from your driver's license, you will need to go to the vehicle management office to attend a 7-day study session on road traffic safety laws, regulations, and related knowledge, and also take a relevant exam. After passing, the points will be reset to zero. Traffic violation deadlines: If a vehicle violates traffic rules and is caught by traffic police on the spot, the police will issue a ticket immediately. Such tickets must be paid at a designated bank within 15 days. If the fine is not paid within 15 days, a 3% late fee will be charged daily, but the total late fee cannot exceed the total fine amount. After a traffic accident, the traffic police will determine responsibility based on the overall circumstances of the accident. The party with violations will be penalized, and this penalty must also be paid within 15 days.
