If the three-way catalytic converter is damaged, such as broken or deformed, it cannot be repaired and must be replaced directly. If it is only clogged, its performance can be restored by cleaning, but if the clogging is severe, replacement is still necessary. More relevant information is as follows: 1. The three-way catalytic converter is the most important external purification device installed in the automobile exhaust system. It converts harmful gases such as CO, HC, and NOx emitted by automobile exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction. 2. When high-temperature automobile exhaust passes through the purification device, the purifying agent in the three-way catalytic converter enhances the activity of CO, HC, and NOx, promoting certain oxidation-reduction chemical reactions. Among them, CO is oxidized at high temperatures into colorless, non-toxic carbon dioxide gas; HC compounds are oxidized into water (H2O) and carbon dioxide at high temperatures; and NOx is reduced into nitrogen and oxygen. The three harmful gases are transformed into harmless gases, thereby purifying the automobile exhaust.

How to Tighten a Loose Handbrake?

If you find that the sensitivity of the handbrake is not ideal, you can adjust the operating copper cable of the handbrake to solve the issue. There is an adjustable compensation mechanism at the bottom of the handle that can be adjusted. Use a jack to lift the rear of the car so that the two rear wheels can rotate freely. For automatic transmissions, shift to the P position. For manual transmissions, shift to 1st or 2nd gear. If it's too tight, the screw may not turn. If it's too loose, the screw may be blocked by internal parts of the handbrake and become invisible. Then, use a wrench to turn the screw clockwise for adjustment. Fully release the handbrake and check whether the rear wheels can rotate. Both rear wheels should be checked to prevent wheel lock-up.

What to Do If the Driver's License Annual Review Expires?

Driver's license annual review expiration is divided into the following three handling methods according to different expiration periods, as detailed below: If the driver's license is overdue for less than one year (not exceeding one year), you can directly apply for a replacement at the vehicle management office, but you still need to participate in the vehicle annual review on time; if the driver's license is overdue for more than one year but less than three years and is in a revocable but recoverable state, you need to take the local subject one exam, and after passing, proceed with the normal replacement procedure—if you fail, you must retake the exam until you pass; if the driver's license is overdue for more than three years, the vehicle management office will revoke the driver's license, and to regain it, you must reapply and pass exams from subject one to subject four. The following are the contents of the motor vehicle driver's license review: Road traffic violations and accident handling status; physical condition; road traffic violation points and participation in study and exams after accumulating 12 points.

The Simplest Method to Find Thirty Centimeters?

Drive the car to the starting point with the front wheels crossing the yellow line. Keep one side of the vehicle approximately 1.5-1.8 meters away from the sideline, then turn the steering wheel fully to the right and reverse. While reversing into the parking space to the right, observe the right-side rearview mirror. As the vehicle moves backward, when the right rear wheel aligns with the extended line of the parking space, turn the steering wheel fully to the right. After entering the parking space, the distance on both sides should generally be maintained at around 30 centimeters.

What to Do If You Lose the Key to Your Scooter?
