How Many Years Before a Private Car Needs to Go Through Inspection?

The time for a motor vehicle to undergo inspection is determined based on the vehicle type. Except for passenger cars which are exempt from inspection for the first 6 years, other vehicle types must undergo inspection according to the specified schedule. Below are the specific details about vehicle annual inspection: 1. Meaning of Annual Inspection: Vehicle annual inspection refers to a mandatory test for all vehicles that have obtained official license plates and registration certificates. It is equivalent to an annual physical examination for the vehicle in accordance with the "Technical Conditions for the Safe Operation of Motor Vehicles." 2. Exemption Policy: Non-commercial small private passenger vehicles with 7 seats or fewer (including 7 seats) are exempt from on-site inspection for the first 6 years. However, the owner still needs to pass an exhaust emission test within the specified period (usually every 2 years) and then apply for an inspection compliance sticker at the vehicle management office, motor vehicle registration service station, or traffic police substation, which must be affixed to the upper right corner of the vehicle's front windshield. 3. Scope of the Exemption Policy: The 6-year exemption policy for non-commercial passenger vehicles and similar vehicles has been in trial implementation since September 1, 2014. Vehicles registered on or after September 1, 2012, are eligible for two exemptions; vehicles registered between September 1, 2010, and August 31, 2012, are eligible for one exemption; vehicles registered before August 31, 2010, must still follow the original inspection regulations for annual review procedures.

What are the two wires of a motorcycle high-voltage coil?

Motorcycle high-voltage coil has two wires: primary coil and secondary coil. Here are the related details: 1. Material: A typical high-voltage coil (ignition coil) contains two sets of coils—primary and secondary. The primary coil uses thicker enameled wire, usually around 0.5-1 mm in diameter, wound approximately 200-500 turns. The secondary coil uses thinner enameled wire, typically around 0.1 mm in diameter, wound approximately 15,000-25,000 turns. One end of the primary coil connects to the vehicle's low-voltage power supply (+), while the other end connects to the switching device (circuit breaker). One end of the secondary coil connects to the primary coil, and the other end connects to the high-voltage output terminal to deliver high-voltage electricity. 2. Ignition Coil: The ignition coil transforms the vehicle's low-voltage electricity into high voltage due to its similar structure to a conventional transformer, with the primary coil having a higher turns ratio than the secondary coil. However, the ignition coil operates differently from a conventional transformer. A conventional transformer works at a fixed frequency of 50Hz, also known as a power-frequency transformer, whereas the ignition coil operates in pulse mode, functioning as a pulse transformer. It repeatedly stores and releases energy at varying frequencies depending on the engine's speed.

Can red light cameras capture violations during rainy days?

Red light cameras can capture violations during rainy days. Regardless of weather conditions, as long as there are traffic light intersections equipped with electronic surveillance, running a red light will be recorded. Penalty points for running a red light: According to Article 2, Section 1, Clause 2 of the "Scoring Standards for Road Traffic Safety Violations," driving a motor vehicle in violation of traffic signal lights will result in a deduction of 6 points. Article 3, Section 1, Clause 8 states that driving a motor vehicle in violation of prohibition signs or markings will result in a deduction of 3 points. How to check for red light violations: Common methods include the following: You can check for red light violations through the "Traffic Management 12123" app. After opening the app, log in using your ID card, then find and click on the "Violation Handling" option. In the violation handling section, you can see the current status of your vehicle. If there are any violations, the specific details will be displayed. You can also check by visiting the service halls of local traffic police branches and using the touch-screen query terminals. Alternatively, you can log in to the external service websites of the local public security traffic management bureaus, find the "Vehicle Violation Query" section, enter your license plate number and vehicle engine number, and click "Query."

What does the wheel specification 245/55r19 mean?

245/55r19 refers to the tire specification, where 245 indicates that the tire section width is 245 millimeters; 55 is the aspect ratio, which means the ratio of the tire sidewall height to the tire section width is 55%; R indicates that the tire has a radial construction, meaning it is a radial tire; 19 refers to the rim diameter of 19 inches. The combination of numbers and letters in 245/55r19 represents the key parameter information of the tire, followed by the load index and speed rating. When selecting tires, it is essential to consider all parameters based on specific conditions. Tires are the only components of a car that come into contact with the ground, affecting the vehicle's driving stability and safety. Tires are rubber products, and prolonged use can lead to aging, so they need to be replaced regularly. Typically, tires installed on a car can last for four years. When purchasing new tires, always check the production date, as unused tires generally have a shelf life of three years. In addition to the model, tires also display the following common data: The sidewall of the tire may have an arrow or the word "OUTERSIDE," indicating the tire's rotation direction. A small umbrella symbol on the sidewall indicates that the tire is suitable for driving in rainy or slippery conditions. Some tires may also include other letters or symbols with special meanings, such as "X" for high-pressure tires, "C" for reinforced tires, "B" for bias-ply tires, and "-" for low-pressure tires. Tire cord materials: Represented by Chinese pinyin, such as M for cotton cord, R for rayon cord, N for nylon cord, G for steel cord, and ZG for steel radial cord tires. Speed rating: Indicates the maximum speed at which the tire can carry a specified load under defined conditions. Letters A to Z represent certified speed ratings ranging from 4.8 km/h to 300 km/h. Common speed ratings include: Q: 160 km/h; H: 210 km/h; V: 240 km/h; W: 270 km/h; Y: 300 km/h. Rim specification: Indicates the rim size compatible with the tire for practical use, e.g., standard rim 5.00F. During daily use of tires, pay attention to the following points: Regularly inspect the tire surface for cracks, deformations, or other defects. Due to wear from driving, the tread grooves gradually become shallower. If the tread wears out, it loses its drainage and anti-slip functions, significantly reducing the car's performance. Small cracks can also pose a risk of tire blowouts at high speeds. Additionally, promptly remove pebbles lodged in the grooves. Park on level ground whenever possible. Avoid parking on roads with thick, sharp, or pointed stones. Do not park near or in contact with petroleum products, acids, or other materials that can deteriorate rubber. After parking, avoid turning the steering wheel, as this accelerates tire wear. Do not splash water to cool tires. In hot weather or during high-speed driving, tires can overheat, and pressure may increase. In such cases, stop to allow the tires to cool naturally. Never release air to reduce pressure or splash water to cool the tires, as this can cause abnormal aging of the tread rubber. Avoid sudden braking. Try to minimize frequent or hard braking to prevent accelerated tread wear caused by dragging the tires against the road surface.
