Is it a problem if the wheel rim gets scratched on the curb?

If the wheel rim gets scratched on the curb, it can be a problem if the damage is severe, and you should go to a repair shop for restoration. The maintenance methods for wheel rims are: 1. When the vehicle is in a humid area, the wheel rims should be cleaned frequently to prevent salt from corroding the aluminum surface; 2. If necessary, after cleaning, you can apply wax to the wheel rims for maintenance to keep them shiny; 3. When the wheel rim temperature is high, let it cool naturally before cleaning. Do not use cold water to clean it, as this can damage the aluminum wheel rim, cause the brake disc to deform and affect braking performance. Using a cleaning agent to clean the wheel rim can cause a chemical reaction on the surface, leading to loss of shine. The wheel rim is the rotating part of the tire's inner contour connected by pillars to the wheel core, supporting the metal component at the center of the tire mounted on the axle.

How many times can you take the C1 license subject one test?

The C1 subject one test can be taken twice. According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," candidates can take the C1 subject one test twice on the same day. If the first attempt is unsuccessful, a second free retake is allowed. If the second attempt also fails, the subject one test is terminated, and the candidate must wait ten days before scheduling another test. Subject one, also known as the theoretical driving test or driver theory test, is part of the motor vehicle driving license assessment. The test covers foundational driving theory, road safety laws and regulations, local regulations, and related knowledge. The test is computer-based with a time limit of 45 minutes. A passing score for subject one is 90 out of 100, with 100 questions consisting of single-choice and true/false questions, each worth 1 point. If a candidate answers 11 questions incorrectly, the system will automatically submit the test and end the session. Subject one test content includes: driving license and motor vehicle management regulations; road traffic conditions and rules; road traffic safety violations and penalties; road traffic accident handling regulations; basic motor vehicle knowledge; local regulations; knowledge of braking systems and safety devices for large and medium-sized passenger and freight vehicles; specialized knowledge for wheeled self-propelled machinery, trams, and trolleybuses. Subject one test precautions: Candidates should dress appropriately—no slippers are allowed. Electronic devices and bags are prohibited in the examination room. Bring your ID card and queue to enter the waiting hall. Observe the instructions and procedures displayed on the screen, and store personal belongings in lockers before entering the examination room. Upon entering, verify your identity at the assigned station and begin the test. Ensure the camera is aligned with you and follow exam discipline. If you fail the first attempt, a same-day retake is allowed. If you fail again, you must pay to reschedule. After the test, queue to collect your score report and sign it—unsigned reports are considered invalid. There is no limit to the number of times you can schedule the subject one test. Each subject allows one test attempt, with one retake if the first attempt fails. If the retake is also unsuccessful, the test is terminated, and the applicant must reschedule. In contrast, subject two and subject three allow only five test attempts each, with rescheduling permitted ten days later. If the subject three safe driving knowledge test is failed, the previously passed road driving skills test scores remain valid. The driving test consists of three subjects: subject one, subject two, and subject three. Subject one covers road traffic safety laws, regulations, and related knowledge. Subject two assesses field driving skills. Subject three is divided into two parts: road driving skills and safe driving knowledge. The safe driving knowledge test is conducted after subject three, often referred to as subject four, though this term is not officially recognized in the Ministry of Public Security's Order No. 123.

What are the symptoms of engine knocking?

Engine knocking can manifest as irregular metallic knocking sounds like "clunk," "click," or "clang" inside the engine, engine vibration, excessively high engine temperature, incomplete fuel combustion resulting in black smoke in the exhaust, reduced engine power, increased fuel consumption, and sudden changes in RPM during normal driving. Below is more information about knocking: 1. Causes of knocking: When the air-fuel mixture combusts in the combustion chamber, the flame spreads outward from the ignition point in a "wave" pattern, so it takes a brief period from ignition to complete combustion of the fuel-air mixture. 2. Knock sensor: The fastest and most effective way to suppress knocking is to retard the ignition timing, thereby reducing combustion pressure. The working principle of the knock sensor is that when engine knocking is detected, it delays the ignition timing to a point where knocking does not occur. Once the engine stops knocking, the ignition timing is gradually restored to its original setting. More advanced knock sensors can even identify which specific cylinder is knocking and individually adjust the ignition timing for that cylinder. 3. Basic concept: Detonation, also known as knocking, is a chemical reaction transmission process accompanied by a significant release of energy. The leading edge of the reaction zone is a shock wave moving at supersonic speed, known as a detonation wave. After the detonation wave passes, the medium becomes a high-temperature, high-pressure detonation product. Systems capable of detonation can be gaseous, liquid, solid, or mixed-phase systems such as gas-liquid, gas-solid, and liquid-solid. Typically, liquid and solid detonation systems are referred to as explosives.
