On which day is the driver's license point reset?

The reset time for driver's license points is the issuance date on the driver's license. The system automatically clears points on the issuance date each year. Scoring cycle and point clearance method: The cumulative scoring cycle for road traffic safety violations is 12 months, with a maximum of 12 points. It is calculated from the date of initial issuance of the motor vehicle driver's license, and so on in a continuous cycle. If the penalty points recorded during one scoring cycle do not reach 12 points, the scoring system will automatically reset the points from the previous cycle at the start of the next scoring cycle. Methods for handling points: Drivers who accumulate 12 points must attend a study session and take an exam at the vehicle management office where the license was issued or at the location where the violation occurred. Only after passing the subject one exam can the points be reset. Otherwise, the driver's license cannot be used normally. If the points do not reach 12 within one scoring cycle, driving is not affected, but the corresponding fine must be paid. After paying the fine, the system will automatically reset the points at the start of the next scoring cycle.

What are the reasons for the difficulty in starting a Chery QQ?

The reasons for the difficulty in starting a Chery QQ may include: battery damage or low charge; abnormal air-fuel mixture or unstable power supply voltage in the ignition system. Battery damage: It needs to be sent to a repair shop for testing with professional computer equipment. Another possibility is low battery charge. If the car is often driven at low speeds with headlights, air conditioning, audio, and other devices frequently turned on, the battery consumption will be higher, potentially leading to low charge. It is recommended to drive at high speeds occasionally to allow the battery to fully charge. Abnormal air-fuel mixture: In this case, the engine usually cranks normally but fails to start. This phenomenon is generally caused by a dirty throttle valve, intake valve, or idle speed control valve. If the valves are too dirty, fuel may spray onto the back and be absorbed by carbon deposits, preventing the engine from starting. Cleaning these components usually solves the problem. Unstable power supply voltage in the ignition system: In winter, the engine's starting resistance increases, including insufficient battery power, leading to inadequate voltage in the entire ignition system. Additionally, sometimes after starting, if the accelerator pedal is not continuously pressed, the car may stall immediately. This is due to a dirty combination of the throttle body and fuel injectors. Slightly increasing the throttle may help, but if the difficulty in starting persists, the car should be sent to a repair shop for a thorough cleaning.

Is it okay to use 95-octane gasoline for a BMW X5?

According to the official vehicle manual recommendation, the BMW X5 should use 95-octane gasoline, so there is no problem with using it. In addition to checking the suitable gasoline grade in the vehicle manual, you can also find it on the fuel tank cap, which will also be marked. Usually, the gasoline grade can also be determined based on the engine's compression ratio. Cars with an engine compression ratio between 8.6-9.9 should use 92-octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95-octane gasoline. However, with the use of some new technologies nowadays, the gasoline grade cannot be determined solely by the compression ratio. A high compression ratio can also be adjusted to use lower-octane gasoline because, besides the compression ratio, other factors such as ignition timing, turbocharging technology, and Atkinson cycle technology also play a role. Generally, the higher the gasoline grade, the higher the octane number and the better the anti-knock performance. 92-octane gasoline contains 92% isooctane and 8% n-heptane, while 95-octane gasoline contains 95% isooctane and 5% n-heptane. If the BMW X5 occasionally uses the wrong gasoline grade, simply switch back to the correct grade after using it up. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles recommended for lower grades, using higher-octane gasoline will not cause damage, but the increase in octane number will change the fuel's ignition point, leading to delayed combustion in the engine. This means both the engine's power output and thermal efficiency will decrease, with the actual feedback being poorer performance. For vehicles recommended for higher grades, using lower-octane gasoline can cause engine knocking. Because the octane number is too low, the gasoline's ignition point decreases, causing it to ignite prematurely during the compression stroke. If the fuel ignites before the spark plug fires during the compression stroke, resistance will occur during the upward stroke. This resistance makes the engine run very unstable. If the knocking is imperceptible, it only increases noise and does not significantly damage the engine. However, if the knocking is noticeable, it indicates severe engine conditions. The vibration not only affects driving stability but also causes abnormal wear on the pistons and cylinders, and in severe cases, can lead to cylinder scoring.

What Does Regular Maintenance of a Car Include?

Regular maintenance of a car includes: 1. Changing the engine oil and oil filter; 2. Replacing the fuel filter, air filter, and cabin air filter; 3. Adding engine coolant and brake fluid; 4. Adding distilled water to the battery electrolyte; 5. Measuring tire pressure; 6. Inspecting the engine belt; 7. Checking the spark plugs. Minor maintenance should be performed every 5,000 kilometers or every six months, while major maintenance is required every 20,000 kilometers or every two years. For new cars, the first maintenance should be done when the mileage reaches 1,500 to 2,000 kilometers, as specified in the maintenance manual provided with the vehicle.
