Motorcycle secondary combustion cannot be blocked. Here are the relevant details: 1. Function: If the secondary air injection system is to be removed, all related tubes must be completely blocked, which is equivalent to removing this system. It is not called secondary combustion; its main function is to inject fresh air into the engine's exhaust gases, converting carbon monoxide in the exhaust into carbon dioxide to meet environmental standards. 2. Environmental Protection: This practice is still for environmental protection. Even older vehicles have the engine's vent pipe connected to the air filter to allow exhaust gases to be burned again, all aimed at environmental protection.

Can a Nail Puncture in the Tire Sidewall Be Repaired?

Tire sidewall punctures cannot be repaired. The sidewall is the weakest part of a tire, consisting of two layers of rubber and two layers of fabric cords. To enhance shock absorption, passenger car tire sidewalls do not incorporate steel belts, and the sidewall undergoes continuous deformation and recovery during rotation. Therefore, if a nail punctures the tire sidewall, the tire should be replaced. Situations requiring tire replacement include: 1. A puncture hole in the tread with a diameter exceeding 6 millimeters; 2. Deformation of the bead or tread, rubber corrosion, or tire damage due to underinflation; 3. The tire has been patched more than four times. Besides nails, stones lodged in the tread grooves can also damage tires. Some sharp stones can quickly cause tire damage through repeated rolling.

When Does the Driving License Point System Reset?

Driving license point reset time: Calculated from the date of initial issuance of the motor vehicle driving license. For example, if your license was issued on January 1st, then every year on this day, the points on your driving license will be reset, and this cycle continues accordingly. The scoring cycle for a driving license is 12 months, with a maximum of 12 points. If the accumulated penalty points during a scoring cycle do not reach 12, the point system will automatically reset the accumulated points from the previous cycle at the start of the next cycle. However, if you accumulate 12 points, you must attend a study session and pass an exam at the vehicle management office where the license was issued or where the violation occurred to have your points reset. Otherwise, your driving license cannot be used normally.
