What are the methods for cleaning carbon deposits in a car?

Methods for cleaning carbon deposits in a car: 1. Remove the engine cover, take off the throttle valve, clean it with carburetor cleaner, dry it with a cotton cloth, and then reinstall it; 2. Open the oil cap, pour in the entire can of cleaner, close the oil cap, start the engine and let it idle for ten minutes before turning it off; 3. Pour the intake system cleaner into the liquid storage tank of a dedicated cleaning device, connect it to the intake system, and start the engine to use vacuum to draw the cleaner into the intake tract for cleaning. Methods to identify carbon deposits in a car: 1. Check the fuel consumption; if the increase continues to rise, it indicates that carbon deposits have formed on the engine; 2. Based on the mileage, the higher the car's mileage, the more carbon deposits will accumulate; 3. Replace with higher-grade gasoline; if there is an improvement in power, it means there is more carbon deposit in the engine.

What causes the automatic headlight washer rod to not retract?

The reasons why the automatic headlight washer rod does not retract are: 1. The headlight washer device is difficult to reset after being blocked by foreign objects. Check if there are any foreign objects stuck inside the washer device. The most common foreign objects are leaves or small stones. After cleaning, normal use can be restored; 2. In winter, when temperatures are low, if the windshield washer fluid is not properly treated for antifreeze, it can freeze directly inside the headlight washer device, preventing the headlight washer device from moving up and down. Method for using the headlight washer device: When the ignition switch is in the 'on' position, turn on the high beams, then pull the wiper control lever toward the driver and hold it for more than 1 second. The front headlight washer device and the windshield washer device will work simultaneously. Once the wiper control lever is released, the windshield washer device will stop spraying the cleaning fluid. Do not use the headlight washer device if there is no cleaning fluid to avoid overheating the motor.

Do I need to take an exam if my driver's license is deducted 11 points?

If your driver's license is deducted 11 points, you do not need to take an exam. Only when all 12 points are deducted will you be required to study and take an exam. If a motor vehicle driver accumulates 12 points within a scoring cycle, the traffic management department of the public security authority shall detain their motor vehicle driver's license. You can apply for 'study to reduce points' through the Traffic Management 12123 mobile app. After studying and passing the exam, you can reduce 1 point each time, with a maximum reduction of 6 points within a scoring cycle. In other words, your driver's license can gain 6 points at this time. The motor vehicle driver shall, within 15 days, go to the traffic management department of the public security authority at the place where the motor vehicle driver's license was issued or where the violation occurred to participate in a seven-day study of road traffic safety laws, regulations, and related knowledge. After the motor vehicle driver completes the study, the vehicle management office shall conduct an exam on road traffic safety laws, regulations, and related knowledge within 20 days.
